The effect of assisted reproductive technology on postpartum bleeding: hormonal cycle frozen embryo transfer might increase blood loss. J Anesth 2024; 38:19-28. [PMID: 37945905 DOI: 10.1007/s00540-023-03268-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 09/29/2023] [Indexed: 11/12/2023]
Abstract
BACKGROUND Among assisted reproductive technologies, frozen thawed embryo transfer (FET) is associated with increased blood loss at delivery. Anesthesiologists need to be aware of new factors that affect postpartum blood loss. This study investigated whether FET cycles with or without hormonal support affect the amount of postpartum bleeding. METHODS We conducted a retrospective cohort study of patients admitted for delivery at a single university hospital between January 2015 and December 2018. Patients were divided into no-assisted reproductive technology (No-ART), hormonal cycle FET (HC-FET) and natural cycle FET (NC-FET) group. The primary outcome was the amount of blood loss after delivery (median [interquartile range]), which was compared among the three groups. Multiple regression analysis was performed to investigate the factors affecting blood loss. RESULTS Between 2015 and 2018, 3187 women delivered neonates. In vaginal delivery, postpartum blood loss in the HC-FET group (1060 [830] g) was significantly greater than in the NC-FET group (650 [485] g, P = 0.001) and in the No-ART group (590 [420] g P < 0.001). Multiple linear regression analysis showed that HC-FET (P < 0.001) was one of the independent factors for the amount of bleeding. In cesarean delivery, the HC-FET group had more blood loss than the No-ART group (910 [676] g vs. 784 [524] g, P = 0.039). However, HC-FET was not an independent factor for postpartum blood loss. CONCLUSIONS The HC-FET group had more blood loss than the No-ART group for both vaginal and cesarean deliveries. Furthermore, HC-FET was an independent factor that increased postpartum blood loss in vaginal deliveries.

[PMID: 37987953 PMCID: PMC10894784 DOI: 10.1007/s10815-023-02982-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 10/23/2023] [Indexed: 11/22/2023] Open
Abstract
PURPOSE The discontinuation of fertility treatment could decrease the chances of achieving parenthood for infertile patients and often leads to economic loss and medical resource waste. However, the evidence on the factors associated with discontinuation is unclear and inconsistent in the context of fertility treatment. This scoping review aimed to summarize the evidence on factors associated with discontinuation in fertility treatment, identify the current knowledge gap, and generate recommendations for future research. METHODS We searched PubMed, Embase, The Cochrane Library, Web of Science, CINAHL, American Psychological Association, and http://clinicaltrials.gov from inception to June 2023 without language or time restrictions. We also searched the grey literature in Open Grey and Google Scholar and hand-searched the reference lists of relevant studies to identify potentially eligible studies. Publications that studied factors associated with discontinuation in fertility treatment were included. The identified factors were mapped to the World Health Organization's treatment adherence model. RESULTS Thirty-seven articles involving 41,973 infertile patients from 13 countries were included in this scoping review. All studies identified the factors from the perspective of patients, except for one that described the factors from the healthcare providers' perspective. A total of 42 factors were identified, with most of them belonging to the patient-related dimension, followed by socio-economic-related, treatment-related, condition-related, and healthcare system-related dimensions. Female education level, social support, and insurance coverage decreased the likelihood of treatment discontinuation, whereas multiparous women, male infertility, depression, higher infertility duration, and treatment duration increased the likelihood of treatment discontinuation. Age, education level, and ethnicity are the commonly nonmodifiable factors for treatment discontinuation, while insurance coverage, depression, and anxiety symptoms are among some of the more commonly reported modifiable factors. CONCLUSION This is the first scoping review examining and synthesizing evidence on the factors influencing of discontinuation in fertility treatment. This review could inform researchers, clinicians, and policymakers to address modifiable barriers and facilitators to develop personalized and multicomponent interventions that could improve the discontinuation in fertility treatment.

Medicine in the marketplace: clinician and patient views on commercial influences on assisted reproductive technology. Reprod Biomed Online 2024; 48:103850. [PMID: 38582042 DOI: 10.1016/j.rbmo.2024.103850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 01/15/2024] [Accepted: 01/20/2024] [Indexed: 04/08/2024]
Abstract
RESEARCH QUESTION What are the views and experiences of patient and expert stakeholders on the positive and negative impacts of commercial influences on the provision of assisted reproductive technology (ART) services, and what are their suggestions for governance reforms? DESIGN Semi-structured interviews were conducted with 31 ART industry experts from across Australia and New Zealand and 25 patients undergoing ART from metropolitan and regional Australia, between September 2020 and September 2021. Data were analysed using thematic analysis. RESULTS Expert and patient participants considered that commercial forces influence the provision of ART in a number of positive ways - increasing sustainability, ensuring consistency in standards and providing patients with greater choice. Participants also considered commercial forces to have a number of negative impacts, including increased costs to government and patients; the excessive use of interventions that lack sufficient evidence to be considered part of standard care; inadequately informed consent (particularly with regard to financial information); and threats to patient-provider relationships and patient-centred care. Participants varied in whether they believed that professional self-regulation is sufficient. While recognizing the benefits of commercial investment in healthcare, many considered that regulatory reforms, as well as organizational cultural initiatives, are needed as means to ensure the primacy of patient well-being. CONCLUSIONS The views expressed in this study should be systematically and critically examined to derive insights into how best to govern ART. These insights may also inform the design and delivery of other types of healthcare that are provided in the private sector.

Abstract
BACKGROUND Heterotopic pregnancies are increasing in incidence with the advent of rising prevalence of in vitro fertilization and embryo transfer (IVF-ET) globally. Although rare, this condition is a serious potentially life-threatening gynaecological complication. CASE PRESENTATION We present the case of a 36-year-old Ghanaian woman who conceived following IVF and presented two weeks after confirmation of intrauterine gestation with sudden onset lower abdominal pain. A diagnosis of ruptured heterotopic pregnancy was made, laparotomy and salpingectomy was done followed with further management of the intrauterine gestation. CONCLUSION To the best of our knowledge, this is the first reported case of heterotopic pregnancy in Ghana. A high index of suspicion for heterotopic pregnancy is required even in the presence of a confirmed intrauterine gestation following IVF-ET.

Abstract
BACKGROUND Access to fertility treatments is considered a reproductive right, but because of the quarantine due to the coronavirus pandemic most infertility treatments were suspended, which might affect the psychological and emotional health of infertile patients. Therefore, this study was conducted to review the mental health of infertile patients facing treatment suspension due to the coronavirus pandemic. METHODS This study was conducted based on the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guideline. The Web of Science, PubMed, Embase, Scopus, and Cochrane library databases were searched by two independent researchers, without time limitation until 31 December 2022. All observational studies regarding the mental health of infertile patients facing treatment suspension including anxiety, depression, and stress were included in the study. Qualitative studies, editorials, brief communications, commentaries, conference papers, guidelines, and studies with no full text were excluded. Quality assessment was carried out using Newcastle-Ottawa Scale by two researchers, independently. The random effects model was used to estimate the pooled prevalence of mental health problems. Meta-regression and subgroup analysis were used to confirm the sources of heterogeneity. RESULTS Out of 681 studies, 21 studies with 5901 infertile patients were systematically reviewed, from which 16 studies were included in the meta-analysis. The results of all pooled studies showed that the prevalence of anxiety, depression, and stress in female patients was 48.4% (95% CI 34.8-62.3), 42% (95% CI 26.7-59.4), and 55% (95% CI 45.4-65), respectively. Additionally, 64.4% (95% CI 50.7-76.1) of patients wished to resume their treatments despite the coronavirus pandemic. CONCLUSION Treatment suspension due to the coronavirus pandemic negatively affected the mental health of infertile patients. It is important to maintain the continuity of fertility care, with special attention paid to mental health of infertile patients, through all the possible measures even during a public health crisis.

Abstract
BACKGROUND Polycystic ovarian syndrome (PCOS) is recognized as the most prevalent endocrine disorder among women of reproductive age. While the utilization of assisted reproductive technology (ART) has resulted in favorable outcomes for infertility treatment in PCOS patients, the inherent pathophysiological features of the condition give rise to complications and consequences during pregnancy and delivery for both the mother and offspring. This study was to assess the correlation between maternal PCOS and various pregnancy complications and neonatal outcomes undergone ART. METHODS A systematic search was conducted on PubMed, EmBase, and the Cochrane Library to identify observational studies that investigated the association between PCOS and the risk of various pregnancy complications and neonatal outcomes, including gestational diabetes mellitus (GDM), hypertension in pregnancy (PIH), preeclampsia (PE), preterm birth, abortion, congenital malformations (CA), small for gestational age (SGA), large for gestational age (LGA), low birth weight (LBW), macrosomia, neonatal intensive care unit (NICU) admission and birth weight. Eligible studies were selected based on predetermined inclusion and exclusion criteria. The meta-analysis was conducted using Review Manager and Stata software, with odds ratios (ORs) or mean difference (MD), confidence intervals (CIs), and heterogeneity (I2) being calculated. The search was conducted up to March 2023. RESULTS A total of 33 studies with a combined sample size of 92,810 participants were identified. The findings indicate that PCOS is significantly associated with an increased risk of GDM (OR 1.51, 95% CI:1.17-1.94), PIH (OR 1.72, 95% CI:1.25-2.39), PE (OR 2.12, 95% CI:1.49-3.02), preterm birth (OR 1.29, 95% CI:1.21-1.39), and LBW (OR 1.29, 95% CI:1.14-1.47). In subgroup analyses, the risks of GDM (OR 1.80, 95% CI:1.23-2.62) and abortion (OR 1.41, 95% CI:1.08-1.84) were elevated in fresh embryo transferred (ET) subgroup, whereas elevated risk of PE (OR 1.82, 95% CI:1.17-2.83) and preterm birth (OR 1.31, 95% CI:1.21-1.42) was identified in frozen ET subgroup. Whatever with or without hyperandrogenism, patients with PCOS had a higher risk in preterm birth (OR 1.69, 95% CI: 1.31-2.18; OR 1.24, 95% CI:1.02-1.50) and abortion (OR 1.38, 95% CI:1.12-1.71; OR 1.23, 95% CI:1.06-1.43). CONCLUSION Our findings suggest that individuals with PCOS undergone ART are at a notably elevated risk for experiencing pregnancy complications and unfavorable neonatal outcomes. Nevertheless, to establish a definitive association between PCOS and pregnancy-related outcomes, it is necessary to conduct extensive prospective, blinded cohort studies and effectively control for confounding variables.

Abstract
Embryo quality is a critical determinant of clinical outcomes in assisted reproductive technology (ART). A recent clinical trial investigating preimplantation DNA methylation screening (PIMS) revealed that whole genome DNA methylation level is a novel biomarker for assessing ART embryo quality. Here, we reinforced and estimated the clinical efficacy of PIMS. We introduce PIMS-AI, an innovative artificial intelligence (AI) based model, to predict the probability of an embryo producing live birth and subsequently assist ART embryo selection. Our model demonstrated robust performance, achieving an area under the curve (AUC) of 0.90 in cross-validation and 0.80 in independent testing. In simulated embryo selection, PIMS-AI attained an accuracy of 81% in identifying viable embryos for patients. Notably, PIMS-AI offers significant advantages over conventional preimplantation genetic testing for aneuploidy (PGT-A), including enhanced embryo discriminability and the potential to benefit a broader patient population. In conclusion, our approach holds substantial promise for clinical application and has the potential to significantly improve the ART success rate.

Abstract
OBJECTIVES To explore the association between assisted reproductive technology (ART) and birth weight discordance in twins (BWDT). METHODS A retrospective analysis was conducted on twin infants born between January 2011 and December 2020 at the Third Affiliated Hospital of Guangzhou Medical University, with complete basic birth data. The impact of ART on the occurrence of BWDT was identified by the multivariate logistic regression analysis. RESULTS A total of 3 974 pairs of twins were included, with 1 431 conceived naturally and 2 543 through ART. Neonates in the ART group had higher birth weights than those in the naturally conceived group (P<0.001). The incidence of BWDT was lower in the ART group compared to the naturally conceived group (16.17% vs 21.09%, P<0.001). The multivariate logistic regression analysis, adjusting for confounding factors such as maternal age, parity, pre-pregnancy body mass index, gestational diabetes, hypothyroidism, gestational age, and chorionic properties, showed no significant difference in the risk of BWDT between the ART and naturally conceived groups (P>0.05). CONCLUSIONS ART is not associated with the risk of BWDT.

Abstract
BACKGROUND Humans are exposed to various chemicals, including organophosphate esters (OPEs), phthalates (PAEs), and phenols. The effects on early reproductive outcomes of in vitro fertilization (IVF) remain unclear. METHODS We recruited 192 women and 157 men who underwent IVF treatment. A total of forty-nine urinary chemicals were detected, including six OPEs, fifteen PAEs, six parabens, two chlorophenols, nine bisphenols, five benzophenones, and six synthetic phenolic antioxidants. We examined the individual and joint effects of parental chemical exposure on early reproductive outcomes. RESULTS We found that certain chemicals were associated with early reproductive outcomes in Poisson regression models. For example, urinary diphenyl phosphate was negatively associated with high-quality embryos in both female (β: -0.12, 95%CI: -0.17, -0.07) and male partners (β: -0.09, 95%CI: -0.15, -0.03). A negative association was found between mixed chemicals and high-quality embryos in Bayesian kernel machine regression, weighted quantile sum regression (β: -0.34, 95%CI: -0.60, -0.07), and quantile-based g-computation model (β: -0.69, 95%CI: -1.34, -0.05) among female partners. Paternal mixture exposure was not associated with early reproductive outcomes. CONCLUSIONS Our results indicated that increased exposure to environmental chemicals was associated with adverse early reproductive outcomes of IVF, especially female partners.

Abstract
BACKGROUND Assisted reproduction technology (ART) has advanced significantly, raising concerns regarding its impact on the secondary sex ratio (SSR), which is the sex ratio at birth in offspring. This study aimed to explore factors affecting SSR in singletons, singletons from twin gestation, and twins from twin gestation within the context of ART. METHODS A retrospective analysis was conducted on data from 8335 births involving 6,223 couples undergoing ART. Binary logistic regression assessed relationships between parental and embryonic factors and SSR in singletons and singletons from twin gestation. Multinomial logistic regression models were utilized to identify factors influencing SSR in twins from twin gestation. RESULTS Secondary infertility (OR = 1.164, 95% CI: 1.009-1.342), advanced paternal age (OR = 1.261, 95% CI: 1.038-1.534), and blastocyst embryo transfer (OR = 1.339, 95% CI: 1.030-1.742) were associated with an increased SSR, while frozen embryo transfer (FET) showed a negative association with SSR (OR = 0.738, 95% CI: 0.597-0.912) in singletons. A longer duration of gonadotropin (Gn) usage reduced SSR in singletons (OR = 0.961, 95% CI: 0.932-0.990) and singletons from twin gestation (OR = 0.906, 95% CI: 0.838-0.980). In singletons from twin gestation, male-induced infertility (OR = 2.208, 95% CI: 1.120-4.348) and higher Gn dosage (OR = 1.250, 95% CI: 1.010-1.548) were significantly associated with an increased SSR. Women aged > 35 years and intracytoplasmic sperm injection (ICSI) were associated with lower SSR (OR = 0.539, 95% CI: 0.293-0.990 and OR = 0.331, 95% CI: 0.158-0.690, respectively). In twins from twin gestation, paternal age exceeded maternal age (OR = 0.682, 95% CI: 0.492-0.945) and higher Gn dosage (OR = 0.837, 95% CI: 0.715-0.980) were associated with a higher proportion of male twins. Cleavage stage transfer (OR = 1.754, 95% CI: 1.133-2.716) resulted in a higher percentage of boy-girl twins compared to blastocyst transfer. CONCLUSION This study demonstrates the complex interplay of various factors in determining the SSR in ART, highlighting the importance of considering infertility type, paternal age, fertilization method, embryo transfer stage, and Gn use duration when assessing SSR. Nevertheless, further research with a large sample size is necessary to confirm and expand upon the findings of this study.

Abstract
BACKGROUND As a novel prognostic and inflammatory marker, the systemic immune-inflammation index (SII) has come to the foreground in recent years. SII may be used as an indicator reflecting the progressive inflammatory process in patients with polycystic ovary syndrome (PCOS). This study aimed to evaluate the correlation between SII and assisted reproductive outcomes in PCOS patients. RESULTS A total of 966 women undergoing in vitro fertilization (IVF) procedure with PCOS were included in the study. The SII was calculated as platelet count (/L) × neutrophil count (/L)/lymphocyte count (/L). Participants were divided into four groups according to SII quartiles calculated at baseline, and the differences of clinical and laboratory outcomes between these four groups were compared. Moreover, a univariate linear regression model was used to evaluate the associations between SII and the outcomes. Patients in the highest SII quartile (Q4) had lower antral follicle count (AFC), estradiol (E2), and progesterone (P) levels on the day of human chorionic gonadotropin (HCG) start compared with the lower three SII quartiles (Q1-Q3). Moreover, our analysis demonstrated that women in the lower SII quartiles had a higher rate of available embryos and blastocyst formation compared with those in the highest SII quartile. Logarithm of SII correlated negatively with available embryo rate, but not with number of available embryos. Additionally, the results of our multivariate logistic regression analyses indicated that the highest SII quartile was negatively associated with biochemical pregnancy rate (BPR), clinical pregnancy rate (CPR), live birth rate (LBR), and implantation rate (IR). A non-linear relationship between the SII and number of available embryos, with a negative relationship seen to the right of the inflection point was also found. CONCLUSIONS The interplay among thrombocytosis, inflammation, and immunity could influence assisted reproductive outcomes in PCOS patients. In this regard, SII may serve as a valuable marker for exploring potential correlations.

Abstract
RESEARCH QUESTION Does fertility treatment, specifically assisted reproductive technology (ART), affect head circumference in term singletons? DESIGN A total of 32,651 women who delivered at term at 12 maternity hospitals in Japan between 2010 and 2018 were included in the analysis; of these, 1941 (5.9%) and 2984 (9.1%) women conceived through ART and non-ART fertility treatments (timed intercourse, ovulation induction or artificial insemination), respectively. The study evaluated the adjusted odds ratios of head circumference ≥90th percentile stratified by infant sex and type of ART procedure after adjusting for covariates, with natural conception as the reference group. RESULTS ART significantly increased the risk of head circumference ≥90th percentile (adjusted odds ratio 1.56 [95% confidence interval 1.25-1.96]), whereas non-ART fertility treatment did not increase the risk (1.14 [0.92-1.42]). This increased risk of head circumference ≥90th percentile was observed exclusively in male neonates (1.73 [1.33-2.26]) and not in female neonates (1.18 [0.76-1.85]) in the ART group. Frozen embryo transfer (FET), FET in a hormone replacement cycle (HRC-FET) and blastocyst-stage embryo transfer were significantly associated with head circumference ≥90th percentile (1.60 [1.26-2.02], 1.70 [1.30-2.22] and 1.72 [1.33-2.24], respectively). CONCLUSIONS The use of ART, particularly FET, HRC-FET or blastocyst-stage embryo transfer, was linked with a heightened risk of head circumference ≥90th percentile compared with non-ART fertility treatment or natural conception. The increased risk was observed only in male neonates.

Abstract
Polycystic ovary syndrome (PCOS) is recognized as one of the most prevalent endocrinopathy in women at reproductive age. As affected women tend to have poorer assisted reproductive technology (ART) outcomes, PCOS has been suggested to endanger oocyte quality and competence development. The aim of this systematic review was to summarize the available evidence on how the follicular fluid (FF) profile of women with PCOS undergoing in vitro fertilization (IVF) treatment differs from the FF of normo-ovulatory women. For that, an electronic search in PubMed and Web of Science databases was conducted (up to December 2021). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA guidelines were followed, and the Newcastle-Ottawa Scale was used to assess the risk of bias in the included studies. Data retrieved from papers included (n=42), revealed that the FF composition of women with PCOS compared to those without PCOS predominantly diverged at the following molecular classes: oxidative stress, inflammatory biomarkers, growth factors and hormones. Among those biomarkers, some were proposed as being closely related to pathophysiological processes, strengthening the hypothesis that low-grade inflammation and oxidative stress play a critical role in the pathogenesis of PCOS. Notwithstanding, it should be noticed that the available data on PCOS FF fingerprints derives from a limited number of studies conducted in a relatively small number of subjects. Furthermore, phenotypic heterogeneity of PCOS hampers wider comparisons and weakens putative conclusions. Therefore, future studies should be focused at comparing well characterized patient subgroups according to phenotypes.

Abstract
BACKGROUND In 2021, France authorized ART with sperm donor for female couples and single women. OBJECTIVES We summarize here the possibilities of ART among LGBT people in France to date, pointing out the main restrictions for LGBT reproductive rights, requiring future legislative changes. RESULTS Despite the latest modification of the French bioethics laws which notably opens ART to female couples, French legislation still excludes most LGBT people from parenthood through ART, especially gay men and transgender people in most cases. Surrogacy, ROPA, co-parenting and directed sperm donation are banned. CONCLUSIONS Legalize ROPA and overcome gender issues for trans people are necessary. A French model of surrogacy is to be considered.

Abstract
Male factor infertility plays a role in approximately 30% of infertility cases. Various causes of male factor infertility exist including congenital, acquired, idiopathic, or environmental factors. Identifying the underlying etiology of male factor infertility is a key step toward providing appropriate counseling, effective treatment options, and improving outcomes for couples with infertility. Although the recent advances and developments in assisted reproductive technology have undoubtedly improved fertility outcomes, clinicians must understand the scope of reproductive urologists in the evaluation and treatment of male infertility to provide comprehensive counseling, appropriate referral, comprehensive evaluation, and correct surgical sperm retrieval techniques when needed.

Abstract
The purpose of this study was to analyse the obstetric outcome after frozen embryo transfer depending on the protocol used. The endometrial preparation during frozen embryo transfer (FET) was performed in the natural cycle (NC) with timing based on monitoring of the naturally occurring luteinizing hormone (LH) peak or in human chorionic gonadotropin (hCG)-triggered modified natural cycles (MNC), artificial cycle (AC) with hormone replacement therapy cycle and cycle with ovulation induction (OI). A retrospective cohort study was conducted between 2018 and 2020. Pregnancy, perinatal complications and neonatal outcomes were compared among patients treated during AC or MNC or OI protocols. After adjusting for the effect of gravidity, parity, pre-pregnancy body mass index (BMI) and number of miscarriages, the AC group had higher but not significantly different rates of gestational hypertension, preeclampsia and intrahepatic cholestasis of pregnancy (ICP) than women in OI and MNC groups. Significant differences were observed in the rates of placental adherence (15.30% in AC vs. 9.24% in MNC, p = 0.004) and postpartum haemorrhage (PPH) (24.33% in AC vs. 13.07% in OI, p = 0.003, 24.33% in AC vs. 16.24% in MNC, p = 0.002) among the three groups. In singletons, significant differences were observed in the rates of placental adherence (14.09% in AC vs. 8.57% in MNC, p = 0.002), AC and MNC groups had higher risk of PPH compared with OI group (18.36% in AC vs. 12.38% in MNC, p = 0.042 and 7.69% in OI vs. 18.36% in AC, p = 0.013). Neonatal outcomes were similar among the three groups except risk of small for date infants (0.35% in AC vs. 1.44% in MNC, p = 0.008). These findings are important in view of increasing use of frozen cycles and new policy of freeze-all cycles in in vitro fertilization (IVF). The results suggest a link between the absence of corpus luteum and adverse obstetric outcomes.

Abstract
There is an increased risk of becoming pregnant through fertility treatments using assisted reproductive technology (ART) during the COVID-19 pandemic. The aim of this review is to gather comprehensive data from the existing literature on the potential risks of fertility management during the pandemic period, and outline strategies to mitigate them, with a focus on the hormonal and surgical procedures of ART. A comprehensive search of the scientific literature on COVID-19 in relation to fertility was conducted in the PubMed database using the keywords "coronavirus," "COVID-19," "SARS-CoV-2" and "pregnancy," "fertility," "urogenital system," "vertical transmission," "assisted human reproduction," "controlled ovarian stimulation," "oocyte retrieval," "in vitro fertilization," "hormones," "surgical procedures," "embryos," "oocytes," "sperm," "semen," "ovary," "testis," "ACE-2 receptor," "immunology," "cytokine storm," and "coagulation," from January 2020-July 2022. Published data on pregnancy and COVID-19, and the interaction of the urogenital system and SARS-CoV-2 is reported. The immunologic and prothrombotic profiles of patients with COVID-19, and their increased risks from controlled ovarian stimulation (COS) and ART surgeries, and how these procedures could facilitate COVID-19 and/or contribute to the severity of the disease by enhancing the cytokine storm are summarized. Strategies to prevent complications during COS that could increase the risks of the disease in pre-symptomatic patients are considered. The impact of SARS-CoV-2 on pre-symptomatic infertile patients presents a challenge to find ways to avoid the increased hormonal, immunologic, and prothrombotic risks presented by the use of COS in ART protocols during the COVID-19 outbreak. Safe ART procedures and recommendations are highlighted.

Abstract
Triptorelin is a first-line drug for assisted reproductive technology (ART), but the low bioavailability and frequent subcutaneous injection of triptorelin impair the quality of life of women preparing to become pregnant. We report silk fibroin (SF)-based microneedles (MNs) for transdermal delivery of triptorelin-loaded nanoparticles (NPs) to improve bioavailability and achieve safe and efficacious self-administration of triptorelin. Triptorelin was mixed into an aqueous solution of SF with shear force to prepare NPs to control the release and avoid the degradation of triptorelin by enzymes in the skin. Two-step pouring and centrifugation were employed to prepare nanoparticles-encapsulated polymeric microneedles (NPs-MNs). An increased β-sheet content in the conformation ensured that NPs-MNs had good mechanical properties to pierce the stratum corneum. Transdermal release of triptorelin from NPs-MNs was increased to ∼65%. The NPs-MNs exhibited a prolonged drug half-life and increased relative bioavailability after administration to rats. Surging levels of luteinizing hormone and estradiol in plasma and their subsequent prolonged downregulation indicate the potential therapeutic role of NPs-MNs in ART regimens. The triptorelin-loaded NPs-MNs developed in this study may reduce the physical and psychological burden of pregnant women using ART regimens.

Abstract
OBJECTIVE Infertility can result from a diminished ovarian reserve, but a potential remedy exists in the form of platelet-rich plasma (PRP) administration. This treatment involves both biological factors and tissue trauma mechanisms, which stimulate folliculogenesis, making it a promising and effective strategy. We assessed the impact of direct PRP injections into the ovaries on the fertility outcomes of women classified as poor responders. METHODS A quasi-experimental study was conducted from April 2021 to December 2022, focusing on patients classified as POSEIDON grade 3 or 4. PRP injections were administered into both ovaries. After 3 months, data were collected on anti-Müllerian hormone (AMH) level, follicle-stimulating hormone (FSH) level, and the numbers of oocytes, mature oocytes, and good-quality embryos following ovarian stimulation. We then compared the data from before and after PRP injection. RESULTS This study included 50 women, with a mean of 39 years (interquartile range [IQR], 35 to 43) and 4 years (IQR, 2 to 6) for age and infertility duration, respectively. FSH levels decreased after treatment, while AMH levels and the numbers of oocytes, metaphase II oocytes, and high-quality embryos increased. However, only the increase in high-quality embryos was significant. The pregnancy and spontaneous pregnancy rates were 20% and 14%, respectively. Notably, women with secondary infertility exhibited a significantly higher pregnancy rate than those with primary infertility. CONCLUSION Ample evidence suggests that PRP can enhance ovarian function. However, further studies are needed to identify the appropriate candidates for this procedure, establish the optimal PRP preparation method, and standardize the procedure for its adjuvant use in assisted reproductive technology cycles.

Abstract
To explore the association between serum-related indicators (levels of inflammatory cytokines and essential trace elements) and miscarriage risk among infertile women undergoing assisted reproductive techniques (ART) on the 14th day after embryo transfer, and to develop and establish a multivariable algorithm model that might predict pregnancy outcome. According to a nested case-control study design, a total of 100 miscarriage cases and 100 live birth controls were included in this study, and women in both groups were infertile and have underwent in vitro fertilization (IVF). Pregnancy tests were performed and serum levels of five essential trace elements (vanadium (V), copper (Cu), zinc (Zn), selenium (Se) and molybdenum (Mo)) and five inflammatory cytokines (interleukin-1β (IL-1β), IL-6, IL-8, IL-10 and tumor necrosis factor-α (TNF-α)) of the participants were measured on the 14th day after embryo transfer. The serum levels of five inflammatory cytokines were determined by multiple magnetic bead enzyme immunity analyzer; and the serum concentrations of five elements were determined simultaneously by inductively coupled plasma‒mass spectrometry (ICP ‒ MS). The logistic regression was used to evaluate the relationship between these serum indices and miscarriage risk among women undergoing ART, and a predictive model of pregnancy outcome based on these indices was established. The levels of IL-10, IL-1β and TNF-α of infertile women in the live birth group were significantly higher than those in the miscarriage group (p = 0.009, p < 0.001, p = 0.006), and the levels of V, Cu, Zn and Se of infertile women in the live birth group were also significantly higher than those in the miscarriage group (all p < 0.001). Through logistic regression analyses, we found that serum levels of IL-1β, TNF-α, V, Cu, Zn and Se were significantly and negatively associated with miscarriage risk. Different combination prediction models were generated according to the results of logistic regression analyses, and the combination of IL-1β, Cu and Zn had the best prediction performance. The area under the curve (AUC) was 0.776, the sensitivity of the model was 60% and the specificity was 84%. In conclusion, the serum-related indicators of women undergoing ART on the 14th day after embryo transfer, including the inflammatory cytokines such as IL-1β and TNF-α and the essential trace metal elements such as V, Cu, Zn and Se, were negatively correlated with miscarriage risk. A multivariate algorithm model to predict pregnancy outcome among women undergoing ART was established, which showed that IL-1β, Cu and Zn might synergistically predict pregnancy outcome.

Abstract
OBJECTIVE To explore whether pregnancy-induced hypertension (PIH) mediates the association between pre-pregnancy body mass index (BMI) and adverse neonatal outcomes in women undergoing assisted reproductive technology (ART) for singleton pregnancies. METHODS This cohort study collected 79437 maternal data from the National Vital Statistics System (NVSS) between 2020 and 2021. Univariable and multivariable logistic regression models were applied to estimate the association between pre-pregnancy BMI and PIH in women receiving ART as well as the associations between pre-pregnancy BMI and PIH and adverse neonatal outcomes. The mediation effect of PIH on the association between pre-pregnancy BMI and adverse neonatal outcomes was estimated according to the total effect, natural direct effect, natural indirect effect, and percentage of mediation. RESULTS There were 25769 participants had adverse neonatal outcomes at the end of the follow-up. After adjusting for confounding factors, an increased risk of PIH in women receiving ART was identified in those with pre-pregnancy BMI ≥25 kg/m2 [odds ratio (OR)=1.92, 95% confidence interval (CI):1.84-2.01]. Pre-pregnancy BMI ≥25 kg/m2 was associated with an increased risk of adverse neonatal outcomes (OR = 1.26, 95%CI:1.22-1.30). Women with PIH had an increased risk of adverse neonatal outcomes (OR = 1.79, 95%CI:1.71-1.87). The percentage mediated by PIH in the association between pre-pregnancy BMI and adverse neonatal outcomes was 21.30%. CONCLUSION PIH partially mediated the association between pre-pregnancy BMI and adverse neonatal outcomes in women receiving ART, which recommends that women control weight before receiving ART.

Abstract
Cryopreservation of embryos is a crucial component of current assisted reproductive technologies (ART). While the ART outcomes for many species have been greatly improved by the introduction of minimum volume vitrification devices, these devices can be difficult to handle and load. To reduce this problem, we recently developed a vitrification carrier which has a highly absorbent surface so that it simply and rapidly removes excess free vitrification solution from the specimen before the cooling step. This Kitasato Vitrification System (KVS) gives excellent results for human and mouse embryo vitrification. This study aimed to determine whether the KVS would also be effective for bovine blastocyst vitrification by comparing outcomes for the control device that was the KVS without excess vitrification solution absorber. The effect of varying the length of time spent in the first equilibration solution (0-10 min) was also evaluated. Vitrification with the KVS resulted in significantly higher survival and hatching rates than with the control device loaded with the same volume of vitrification solution (survival: 98.6% vs 87.6%, hatching at 72 h post warming: 87.3% vs 66.7%, respectively). The best outcomes were obtained with a 10 min equilibration step prior to exposure to the vitrification solution for 30 s. We also evaluated the effect of embryo quality on blastocyst viability when using the KVS. Survival rates of high- and low-quality embryos were comparable but low quality embryos had significantly lower hatching rates. Overall, the results indicate that the KVS vitrification device is effective for bovine blastocyst vitrification.

Abstract
The objective of this study was to investigate the optimal controlled ovarian hyperstimulation (COH) protocol for patients aged 35 and above with poor ovarian response (POR), utilizing real-world data. This retrospective cohort study examined clinical information from a total of 4256 patients between January 2017 and November 2022. The patients were categorized into three groups: modified GnRH agonist protocol (2116 patients), GnRH antagonist protocol (1628 patients), and Mild stimulation protocol (512 patients). Comparative analysis was conducted on clinical variables and pregnancy outcomes across the three groups. The GnRH agonist protocol was associated with a higher number of oocyte number (4.02 ± 2.25 vs. 3.15 ± 1.52 vs. 2.40 ± 1.26, p < 0.001), higher number of transferable embryos (1.73 ± 1.02 vs. 1.35 ± 1.22 vs. 1.10 ± 0.86, p = 0.016), higher cumulative live birth rate 28.50(603/2116) vs. 24.94(406/1628) vs. 20.51(105/512), p < 0.001) than GnRH antagonist protocol and Mild stimulation protocol, the Mild stimulation protocol was associated with a higher miscarriage rates 16.27(62/381) vs. 16.61(48/289) vs. 32.22(29/90), p = 0.001) than the other two groups. Therefore, it can be concluded that all three protocols can be used in patients over 35 years old with poor ovarian response. However, if patients require more frozen-thawed embryo transfers to achieve better cumulative live birth rates, the modified GnRH agonist protocol may be the preferable option.

Abstract
INTRODUCTION Successful frozen-thawed embryo transfer (FTET) depends on multiple factors among which the woman's vaginal microbiota has recently been considered important. Using probiotic products, such as Lactovag in infertile women, the vaginal microbiome can become close to the healthy status. OBJECTIVES The aim of this study was to evaluate the effect of Lactovag on normalizing vaginal microbiome, as well as its role in improving pregnancy outcomes in FTET cycles. PATIENTS AND METHODS This randomized blinded clinical trial was conducted on 103 patients undergoing Assisted Reproductive Technology (ART) treatment at a tertiary university-based hospital between January and August of 2019. In the experiment group, the vaginal suppository Lactavag was prescribed, whereas in the control group, patients did not receive any microbiome supplements. Then, the pregnancy rate was compared in the two groups. RESULTS There were no significant differences in baseline characteristics between the two study groups (p > 0.05). Positive B hCG was present in 28% (n = 26) of women, clinical pregnancy was achieved in 23.4% (n = 22) of them and fetal heart rate was detected in 21.3% (n = 20). These proportions were higher in the Lactovag group, although these differences were not significant (p > 0.05). Results showed that although transferring fetuses with grade A increased the odds of pregnancy with 1.53 (p = 0.001) folds, this ratio would be improved using Lactovag;1.68 (P value = 0.008). CONCLUSIONS It seems that the vaginal microbiota critically interplays with women's health and reproduction. A probiotic agent such as Lactovag can be useful in normalizing this environment and improving pregnancy outcomes in infertile women.

Abstract
BACKGROUND In Indian context, infertility is often a silent struggle. Despite the high prevalence of infertility in the country, the majority of couples do not share their struggles with family or friends due to social stigma, thus increasing their psychological vulnerability. Heartfulness meditation has shown to decrease stress, anxiety, loneliness and improve sleep along with quality of life. OBJECTIVES The current retrospective series evaluated the effectiveness of Heartfulness-based integrative therapy on infertility outcomes. METHODS The program consisted of a 5- day onsite lifestyle modification workshop and online follow up meditation sessions. RESULTS 54 couples with infertility participated in the program with a mean age of 30.74 years (SD 5.04) for females and 34.03 years (SD 4.54) for males. 15 couples presented with male infertility, 16 couples presented with female infertility and in 5 couples both partners had infertility problems. Further, 18 couples had unexplained infertility. 24 couples conceived with 18 natural conceptions, five via assisted reproductive technology and one spontaneous abortion. CONCLUSION The program was beneficial in the cohort who utilized it as prescribed resulting in conception of 24 out of 54 couples. Future research investigating the causal relationship of Heartfulness meditation on fertility outcomes in a randomized control study could solidify this treatment method to be used independently or as an adjuvant therapy with assisted reproductive technologies.

Abstract
BACKGROUND Declining oocyte quality in women with advanced age has been a major impediment to assisted reproductive treatments' (ART) success rate. However, aging is often accompanied by a diminished ovarian reserve (DOR). Cumulus cells (CCs) are known to play an important role in the development and maturation of oocytes, and the quality of CCs actually reflects the quality of the oocyte. In this study, CCs were used to investigate the real reasons for the decline in oocyte quality in older women. METHODS Ninety-nine CC samples were subdivided into 4 different groups according to the different age and ovarian reserve status. Other than clinical ART results, transcriptional expression profiles were performed in CCs to detect the differences. RESULTS The results were that DOR, no matter in young or advanced age group, was found to be significantly associated with adverse ART outcomes. Of note, there were no statistically significant changes in ART outcomes in the group at advanced age with normal ovarian reserve (NOR), compared to the young with NOR. DOR induced a series of transcriptional variations in CCs commonly enriched in oxygen metabolism. CONCLUSION Our results revealed that the ART outcomes in advanced patients were attributable to the DOR. The oxygen metabolic changes may interfere with CCs' function of supporting oocytes. This study can provide guidance for ART practice that not age but ovarian reserve status is the main predictor for ART outcomes, and ovarian reserve status should be timely assessed when the clinical manifestations are still mild in elderly women.

Longitudinal changes of oxidative stress and PON1 lactonase activity and status in older pregnant women undergoing assisted reproductive technology: a prospective nested case-control study. Reprod Biol Endocrinol 2023; 21:97. [PMID: 37885002 PMCID: PMC10601164 DOI: 10.1186/s12958-023-01139-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 09/12/2023] [Indexed: 10/28/2023] Open
Abstract
BACKGROUND Childbearing in women with advanced maternal age (AMA) has increased the need for artificial reproductive technology (ART). ART and oxidative stress are associated with many pregnancy complications. Paraoxonase (PON) 1 is one of the key components responsible for antioxidative activity in high-density lipoprotein (HDL). This study aimed to investigate the longitudinal changes of oxidative stress and PON1 lactonase activity and status in older women undergoing ART. METHODS This prospective nested case-control study included 129 control and 64 ART women. Blood samples were obtained respectively at different stages of pregnancy. PON1 level and lactonase activity were assessed using 7-O-diethylphosphoryl-3-cyano-4-methyl-7-hydroxycoumarin (DEPCyMC) and 5-thiobutyl butyrolactone (TBBL) as a substrate, respectively. A normalized lactonase activity (NLA) was estimated based on the ratio of TBBLase to DEPCyMCase activity. Serum total oxidant status (TOS), total antioxidant capacity (TAC), malondialdehyde (MDA), homocysteine (HCY), PON1 C-108T and Q192R genetic polymorphisms, and metabolic parameters were analyzed. RESULTS Lactonase activity and level of PON1 gradually decreased with pregnancy progression, while glycolipid metabolism parameters and TAC levels increased with pregnancy progression or significantly raised during the 2nd and 3rd trimesters, and NLA of PON1, TOS, OSI, MDA, and HCY significantly increased before delivery in the ART and control groups. Compared with the control women, the ART women had substantially higher or relatively high lactonase activity and NLA of PON1 and TAC during pregnancy; higher triglyceride (TG), total cholesterol, low-density lipoprotein cholesterol, atherogenic index, apolipoprotein (apo) B, and apoB/apoA1 ratio in the 1st trimester; and higher fasting glucose, fasting insulin, homeostatic model assessment of insulin resistance, and TG levels before delivery. No significant differences were found in the frequencies of PON1 C-108T and Q192R genotypes and alleles between the ART and control groups. CONCLUSIONS Women with AMA undergoing ART had higher TAC, PON1 lactonase activity, and PON1 NLA than control women, suggesting increased compensatory antioxidant capacity in ART women, thus showing higher sensitivity to oxidative stress-related injury and diseases.

Singleton pregnancy using in vitro fertilization or intracytoplasmic sperm injection does not increase risk of bleeding in cesarean delivery: a retrospective cohort study. J Anesth 2023; 37:769-774. [PMID: 37612435 DOI: 10.1007/s00540-023-03234-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 07/22/2023] [Indexed: 08/25/2023]
Abstract
PURPOSE Several studies indicate that assisted reproductive technology (ART) including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies carries increased risk of complications including postpartum hemorrhage (PPH). However, the association between IVF/ICSI and the bleeding risk particularly in cesarean delivery has not been systematically assessed. The aim of this study was to evaluate bleeding risk during and after cesarean delivery in parturients who conceived using IVF or ICSI. METHODS This is a retrospective observational study analyzing data from 310 parturients who underwent cesarean delivery: 155 who had conceived using IVF or ICSI (IVF/ICSI group) and 155 age and year of delivery matched controls who had conceived spontaneously (control group). The primary outcome measure was the amount of blood lost during and within 24 h after cesarean delivery. Secondary outcome measure was the incidence of severe PPH. With 132 parturients in each group, we had 90% power to detect a 200 mL difference in the bleeding amount, at a 0.05 two-sided significance level. RESULTS The amount of bleeding in the IVF/ICSI group was 1234 ± 669 mL, which was 124 mL (11.2%) greater than that in the control group (95% CI - 34 to 282; p = 0.12). The incidence of severe PPH in the IVF/ICSI group and in the control group was 23.9% and 16.8%, respectively (p = 0.16), and the unadjusted odds ratio was 1.6 (95% CI, 0.9-2.7; p = 0.12). No significant independent effect of IVF/ICSI on the bleeding amount and the incidence of severe PPH was observed in multivariable regression analyses (p = 0.22, p = 0.16). CONCLUSION In this study, IVF and ICSI were not associated with increasing risk of bleeding in cesarean delivery.

Abstract
Ovarian stimulation for assisted reproductive technology is traditionally started in the early follicular phase. The essential rationale is to allow timely follicle growth and oocyte retrieval to ensure synchronization of the in-vitro cultured embryos with the receptive period of the endometrium in a fresh transfer cycle. In addition, conventional thought suggested that follicle recruitment happened only once, around menstruation. A deeper understanding of folliculogenesis, advances in cryobiology and an increasing proportion of freeze-all cycles provide a unique opportunity here. Experience from oncofertility patients as well as infertile women and oocyte donors who underwent ovarian stimulation in different phases of the menstrual cycle, dubbed 'random start' cycles, suggests that the number of oocytes collected and their reproductive potential do not depend on the time of starting ovarian stimulation, although the duration of stimulation and gonadotrophin consumption can vary slightly. It may be time to free both patients and clinics from the obsession with starting ovarian stimulation in the early follicular phase in planned freeze-all cycles. The flexibility provided by random start cycles is one aspect of individualizing treatment to patients' needs.

Abstract
RESEARCH QUESTION Is patient satisfaction higher with telemedicine visits or in-person visits for an initial consultation in the ambulatory fertility setting? DESIGN A survey study of fertility patients who had an initial consultation visit between January 2018 and September 2022 was conducted using a nationally distributed survey. Patient satisfaction and other outcomes pertaining to patient experience were compared between telemedicine and in-person visits. RESULTS In total, 682 participants completed the survey nationwide; of these, 425 respondents had an in-person visit and 257 respondents had a telemedicine visit. Age, geographic region, race, education level, employment status, income level and marital status did not differ between the groups. Overall, 69.6% of participants were satisfied with telemedicine visits, with improvement in partner participation. More patients were satisfied with in-person visits compared with telemedicine visits (82.6% versus 69.6%, P<0.001), and more patients preferred in-person visits to telemedicine visits regardless of the type of appointment they had for their initial visit. In a subgroup analysis of patients seen during the coronavirus disease 2019 pandemic, patients who had telemedicine visits were younger, more likely to be White, more educated and had a higher income compared with patients who had in-person visits. CONCLUSIONS Previously, the impact of telemedicine in the fertility setting was largely unknown. This study demonstrated that the majority of patients were satisfied with health care through telemedicine visits. However, patients were more satisfied with in-person visits, and preferred in-person visits to telemedicine visits. Further studies are needed to help clarify the differences in patient satisfaction with visit type, and to assess the role of telemedicine in future fertility care.

Abstract
Background The efficiency of in vitro fertilization is improved by growth hormone (GH) during ovarian stimulation. Additionally, patients with diabetes experience impaired insulin resistance and compromised glucose tolerance, which further exacerbate their condition. Due to these side effects, in this study, the duration of GH treatment was compared in IVF/ICSI cycles among poor ovarian responders. Methods In this study, POSEIDON criteria were used to choose patients. Subcutaneous administration of gonadotropin-releasing hormone (GnRH) antagonist was done beginning on the sixth day of the cycle and continuing through the day of human chorionic gonadotropin (hCG) injection. In one group, GH was administered 4 units/day from the 2nd day of the cycle until hCG injection, and in another group, the first dose was administered on the 6th day of the cycle. Following the administration of hCG, which lasted from 24 to 36 hr, oocytes were retrieved with the support of B-mode sonography. Results In our analysis, no significant differences were observed between the two groups in terms of the number of retrieved oocytes, metaphase II oocytes, and quality of grade A and B embryos. The results show that the treatment or conditions did not have a significant impact on the outcomes among the studied groups. Conclusion Our findings indicate that a shorter duration of GH administration can yield similar outcomes compared to a longer duration in IVF/ICSI cycles involving poor ovarian responders. This result holds the potential for a more cost-effective and patient-friendly approach in managing assisted reproductive technology procedures. It may lead to reduced side effects and improved adherence to medication regimens in patients.

Does Testicular Sperm Improve Intracytoplasmic Sperm Injection Outcomes for Nonazoospermic Infertile Men with Elevated Sperm DNA Fragmentation? A Systematic Review and Meta-analysis. Eur Urol Focus 2023:S2405-4569(23)00191-8. [PMID: 37709593 DOI: 10.1016/j.euf.2023.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 08/17/2023] [Accepted: 08/31/2023] [Indexed: 09/16/2023]
Abstract
CONTEXT For nonazoospermic infertile men with elevated sperm DNA fragmentation (SDF), it is unclear whether the use of testicular sperm for intracytoplasmic sperm injection (ICSI) may offer advantages over ejaculated sperm. OBJECTIVE To determine whether ICSI outcomes (fertilisation rate, pregnancy rate, miscarriage rate, and live birth rate) are better with testicular sperm than with ejaculated sperm for men with elevated SDF. EVIDENCE ACQUISITION We searched the Cochrane Central, EMBASE, MEDLINE, Web of Science, and Scopus databases (1946-2023) in February 2023 for relevant human comparative studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. EVIDENCE SYNTHESIS Out of 2032 records, nine studies (more than 536 participants, mean age range 33-40.5 yr for males and 30.1-37.9 yr for females) were included in the systematic review and meta-analysis. Pooled estimates demonstrated that the pregnancy rate was significantly higher with testicular than with ejaculated sperm according to a sperm chromatin structure assay (SCSA)/sperm chromatin integrity test (SCIT) (odds ratio [OR] 2.51; p = 0.001) and terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) assays (OR 3.65; p = 0.005). The live birth rate was significantly higher according to SCSA/SCIT (OR 2.59; p = 0.005). There were no significant differences in the fertilisation rate or miscarriage rate. CONCLUSIONS Although significant improvements in pregnancy and live birth rates were observed with testicular sperm, the strength of findings is limited by availability and quality of evidence, both of which undermine recommendations for clinical practice. Standardised randomised controlled trials are needed to definitively determine whether the use of testicular sperm improves ISCI outcomes for men with high SDF. Until such evidence exists, ICSI after testicular sperm extraction or aspiration should not be routinely performed. PATIENT SUMMARY Our review showed that for infertile men with a high level of DNA damage in their sperm, use of sperm extracted from the testicles may give better results than ejaculated sperm for a particular IVF (in vitro fertilisation) technique. However, there is a lack of high-quality data.

Abstract
OBJECTIVE Abdominal trachelectomy (AT) is a fertility-preservation surgery for patients with early-stage cervical cancer. Few studies have reported the outcomes of assisted reproductive technology (ART) in patients after AT. The aim of this study was to evaluate the outcomes of ART after AT. STUDY DESIGN In this retrospective study, we compared the ART outcomes of 13 patients who underwent AT at another hospital prior to undergoing ART at our clinic (T group) and 52 control patients (non-T group) who did not undergo AT prior to ART, selected on the basis of age, time of treatment onset, and serum anti-Müllerian hormone concentrations, matched 1:4, respectively. RESULTS Cumulative live birth rates were 62% (8/13) and 65% (34/52) in the T and non-T groups, respectively (p = 0.795). The total number of oocyte retrieval cycles was 34 in the T group and 95 in the non-T group. In all oocyte retrieval cycles, no significant differences were noted in the number of oocyte retrievals, rate of fertilization, and presence of good-quality blastocysts (Gardner classification ≥ BB). The total number of embryo transfer (ET) cycles was 55 in the T group and 109 in the non-T group. The pregnancy and live birth rates per ET were lower in the T group than those in the non-T group (pregnancy rate, 20% vs. 39%, p = 0.017; live birth rate, 15% vs. 30%, p = 0.028; respectively). Endometrial thickness before ET was lower in the T group vs. the non-T group: median (range): 7.4 (3.5-14.3) mm vs. 9.0 (5.5-14.9) mm, respectively; p < 0.0001. Multivariate logistic regression models showed that age at oocyte retrieval (adjusted odds ratio [OR], 0.76; 95% confidence interval [CI], 0.66-0.87), use of good-quality blastocysts (adjusted OR, 3.23; 95% CI, 1.20-8.67), and history of AT (adjusted OR, 0.28; 95% CI, 0.11-0.72) were associated with the pregnancy rate per ET. CONCLUSION The pregnancy rate per ET was lower in patients with vs. without a history of AT. Clinicians should be aware of the longer time to pregnancy in patients who undergo ART after AT.

Abstract
PURPOSE Multiple morphological abnormalities of the sperm flagella (MMAF) are a severe form of sperm defect causing male infertility. Previous studies identified the variants in the CFAP69 gene as a MMAF-associated factor, but few cases have been reported. This study was performed to identify additional variants in CFAP69 and describe the semen characteristics and outcomes of assisted reproductive technology (ART) in CFAP69-affected couples. METHODS Genetic testing with next-generation sequencing (NGS) panel of 22 MMAF-associated genes and Sanger sequencing was performed in a cohort of 35 infertile males with MMAF to identify pathogenic variants. Morphological, ultrastructural, and immunostaining analyses were performed to investigate the characteristics of probands' spermatozoa. ART with intracytoplasmic sperm injection (ICSI) was carried out for the affected couples to get their own progenies. RESULTS We identified a novel frameshift variant in CFAP69 (c.2061dup, p. Pro688Thrfs*5) from a MMAF-affected infertile male with low sperm motility and malformed morphology of sperm. Furthermore, transmission electron microscopy and immunofluorescence staining revealed that the variant induced the aberrant ultrastructure and reduction of CFAP69 expression in the proband's spermatozoa. Moreover, the partner of the proband birthed a healthy girl through ICSI. CONCLUSIONS This study expanded the variant spectrum of CFAP69 and described the good outcome of ART treatment with ICSI, which is beneficial to the molecular diagnosis, genetic counseling, and treatment of infertile males with MMAF in the future.

Abstract
Glutathione is an important antioxidant found in all mammalian cells. Sperm motility is positively correlated with seminal reduced glutathione (GSH) levels, and infertile men are known to have lower GSH levels. Studies on GSH supplementation in improving sperm functions in infertility patients are limited. Here, we re-investigate the effect of exogenous GSH supplementation on human sperm motility and kinematic parameters. Residual semen samples from 71 infertility patients who came for routine semen analysis for infertility assessment were studied. Liquefied raw semen was supplemented with GSH (0-10 mM) for 1 h. The untreated sample was the blank control. Only a 5 mM concentration was tested in all 71 samples. After two washes, the sperm was incubated and then analyzed for sperm motility and kinematic parameters by computer-assisted semen analysis (CASA), followed by adenosine triphosphate (ATP), reactive oxygen species (ROS) levels, free thiols, and DNA damage analyses. At 2 hrs post-treatment, GSH supplementation significantly altered many of the kinematics, compared to the control. Straight line velocity (VSL) (p = 0.0459), curvilinear velocity (VCL) (p < 0.0001), average path velocity (VAP) (p < 0.0001), and lateral head amplitude (ALH) (p < 0.0001) were decreased, whereas straightness (STR) (p = 0.0003), linearity (LIN) (p = 0.0008), and beat cross frequency (BCF) (p = 0.0291) were increased in 5 mM group. Wobble (WOB) (p = 0.4917), motility (MOT) (p = 0.9574), and progressive motility (PROG) (p = 0.5657) were unchanged. ATP level was significantly increased in the 5 mM group (p < 0.05). It is concluded that exogenous GSH supplementation does alter sperm kinematics in humans. These altered kinematic parameters together with increased energy (ATP) may have a positive role in influencing the success rates of ART procedures.

Abstract
PURPOSE OF REVIEW We summarized recent available data to assess the association between assisted reproductive technology (ART) and risk for preeclampsia. RECENT FINDINGS The majority of clinical studies supporting the association of preeclampsia and ART are retrospective. Published data from both clinical and pre-clinical studies suggest specific ART procedures may contribute to the increased risk, including in vitro embryo handling and development, hormone stimulation, transfer cycle types, and use of donor oocytes/embryos. Potential mechanisms include epigenetic aberrations leading to abnormal placentation, absence of factors secreted by the corpus luteum, and immunologic responses to allogenic gametes. There is an increased risk of preeclampsia following ART. Treatment plans that favor reduced preeclampsia risk should be considered for ART pregnancies. To make ART pregnancies safer, additional clinical and animal model studies are needed to elucidate the underpinnings of this risk association.

Abstract
OBJECTIVE The COVID-19 pandemic has been the most serious public health emergency encountered in modern assisted reproductive technology (ART) development. In order to identify lessons learned, this study reviews the effect of the pandemic on ART institutions and human sperm banks in China, and summarizes the experiences and reflections of Chinese scholars post-pandemic era. METHODS This review is based on multiple consensus statements on the COVID-19 pandemic issued by Chinese experts as well as current national regulations and principles in ART institutions and human sperm banks to document the current situation of ART services in China, describe the impact of the pandemic on these services, and offer Chinese reflections on worrying issues in the post-pandemic era. RESULTS China reached one million ART cycles in 2016, and there are currently 540 ART medical institutions and 27 human sperm banks, with 540 licensed for AIH, 91 for AID, 415 for conventional IVF and ICSI and 85 for PGT. Of these, only 4 institutions carry out 10,000 cycles or more annually, and the proportion of institutions with less than 1,000 cycles has reached 66%, which means that a considerable number of ART institutions are still not saturated. As a consequence of the COVID-19 pandemic, 63.6% of ART providers and 95.5% of human sperm banks suspended operations. By the end of May 2020, China, as an early country affected by the pandemic achieved a national resumption rate of ART medical services of 99.2% and that of human sperm banks of 100.0%. Reports from the first and largest human sperm bank in China showed that qualification, semen concentration and sperm viability rates measured at primary screening have significantly decreased post-pandemic. Much like in other countries, Chinese experts developed a consensus on prevention and control measures during the pandemic. In principle, all ART activities should be suspended during acute phases of infection spread. Chinese scholars highlight that attention should be paid to young patients with fertility requirements during and after COVID-19, and emphasize the importance of fertility evaluation and clinical intervention. In addition, couples should be reminded that during ART treatment, disinfectants should not be used excessively to minimize risks of damaging the reproductive system, gametes and zygotes. At the same time, timely and reasonable guidance for tackling negative emotions from stress response is needed to provide reassurance and to avoid irrational fear and excessive stress. Seminal parameters should be re-examined 2 months after SARS-CoV-2 vaccination, and ART treatments recommenced if no abnormalities are detected. CONCLUSIONS Given the growing frequency of outbreaks of global infectious diseases in recent years, ART institutions and human sperm banks should pay attention to improving their prevention and control capabilities. To a certain extent, decisions and measures adopted in China during COVID-19 pandemic are worthy of recognition and acceptance. Chinese scholars have discussed, proactively responded to and understand the key issues surrounding ART development during the pandemic with the aim of contributing to the substantial progress and healthy development of ART services in the world.

Abstract
Rapid advances in assisted reproductive technology have revolutionized fertility treatments for couples worldwide seeking a pregnancy. Although this is promising, concerns are emerging over the overuse of unnecessary assisted conception treatments, particularly among couples with anovulatory subfertility. Some experts are calling for the cessation of ovulation induction as the primary treatment of anovulatory subfertility in favour of more sophisticated assisted conception treatments. In the absence of other causes of subfertility, ovulation induction in patients with type 1 and type 2 anovulation disorders can achieve an up to 80% ovulation rate with a 40% cumulative pregnancy rate and few adverse effects. Considering the various risks and high costs associated with assisted reproductive technology treatments, it is hard to argue for their cost-effectiveness when simpler, safer and cheaper pharmacological ovulation induction could achieve comparable pregnancy rates. We argue here for the safe, effective and ethical use of ovulation induction in this population, supplemented by a judicious use of assisted conception treatments. We emphasize the essential role of ovulation induction as a first-line intervention for couples with anovulatory subfertility delivered within a patient-centred multidisciplinary care model and with a clear escalation pathway to use assisted reproductive technology treatments based on the person's response, characteristics and treatment preference.

Abstract
OBJECTIVE This study aimed to compare the effects of two brands of commercial vitrification carriers on pregnancy outcomes in freeze-thaw cycles. METHODS We included 4871 patients who underwent a "freeze all" strategy using the commercial carriers J.Y. straw and OYASHIPS straw in the Reproductive Center of the First Hospital of Jilin University. The pregnancy outcomes of cleavage-stage embryos and blastocysts were studied separately. Detailed data and the safety of children born from mothers with the two types of carriers were also compared. RESULTS Patients who used J.Y. straw had similar clinical pregnancy and live birth rates with one and two cleavage-stage embryo transplantation to those who used OYASHIPS straw. In patients who had blastocyst transplantation, the clinical pregnancy rate of one blastocyst transplanted in those who used OYASHIPS straw was significantly higher than that in those who used J.Y. straw (57.85% vs 47.09%). Among children born from mothers who used J.Y. straw, the congenital disability rate was significantly higher than that in those with OYASHIPS straw. CONCLUSION The OYASHIPS straw carrier is cheap and can achieve clinical pregnancy and live birth outcomes comparable to those of J.Y. straw. Therefore, OYASHIPS straw is a good alternative option.

Abstract
RESEARCH QUESTION What is the current availability of treatment with assisted reproductive technology (ART) in the public sector in Africa, and what are the facilitators and barriers towards its provision? DESIGN Cross-sectional quantitative and qualitative data were collected in two phases from February 2020 to October 2021. Key informants were identified from countries known to provide ART in Africa based on data from the African Network and Registry for Assisted Reproductive Technology and the 2019 Surveillance from the International Federation of Fertility Societies. Quantitative data were collected via a structured questionnaire (Phase 1); public centre-specific quantitative and qualitative data were then collected via a semi-structured questionnaire followed by a virtual interview (Phase 2). Data were analysed descriptively. RESULTS Informants from 18 countries reported the existence of 185 ART centres in 16 countries. Twenty-four centres (13.0%) in 10 of 16 countries (62.5%) were public. The majority of public centres (20/22 [90.9%]) reporting on ART performed <500 ART cycles per annum. Although public institutions covered most of the cost for ART, copayments from patients were universally required. The number of ART cycles per annum was inversely correlated to the copayment. Lack of policy and legislation, high costs and bureaucratic obstacles were identified by participants as the leading challenges in the delivery of public service ART. CONCLUSION Lack of public ART services leads to chronic and profound health inequities. Enablers of public service ART in the region are the same known to support ART services in general, namely policy and legislation, appropriate funding and good health service infrastructure. Addressing these requires the collated efforts of many stakeholders.

Abstract
BACKGROUND The desire for fertility is the manifestation of yearning for immortality. Infertility and assisted reproductive technology (ART) expose couples to great affective, anxiety, stress, and financial burden. Increasing evidence emphasize the impact of lifestyle on infertility. One of the most crucial factors affecting the fertility process is the nutrition patterns, the amount and quality of physical activities, emotional problems management; modulate stressors, relief from anxiety, and the living conditions of couples. Most ART treatment interventions in Iran are not integrated into lifestyle programs. Therefore, this research will investigate the impact of mixed fertility health-promoting programs in couples who use ARTs. METHODOLOGY/DESIGN This study entails three steps. The first step includes the systematic review of literature on a health-promoting lifestyle in infertile couples undergoing ARTs, a systematic review of observational studies and interventions in couple's lifestyle, then, a systematic review of qualitative studies on infertility in couples and their lifestyle, and in the final step couple's life style literature systematically will evaluate in Iran. In case of failure to obtain the required results from systematic reviews, cross-sectional studies will be carried out to determine the lifestyle of infertile couples receiving ARTs. In the second stage, by holding a panel of experts, an intervention is planned based on the results of the previous stages in order to improve the lifestyle of couples. In the final step, the designed intervention will be administered as a random clinical trial-on ART candidates, in intervention or control groups in one of Iran University of Medical Sciences hospitals. Afterward, the data's will be evaluated by using standard questionnaires, that include health-promoting lifestyle questionnaire (HPLII), Beck's depression inventory (BDI), international physical activity questionnaire-short form (IPAQ-SF), and food frequency questionnaire (FFQ). The statistical analysis will be carried out in SPSS software. During the study, subjects meeting the inclusion criteria were randomly selected and randomized into the intervention and control groups. The health-promoting lifestyle training program will be executed for the intervention group while the standard care program is administered to the control group. The content of this program will be obtained from the consensus opinions of the expert panel. The program includes diet recommendations, physical activity, and stress management. Appropriate time, frequency, duration and number of activities will be considered. Communication with subjects will be possible through private meeting special comfort room. Support to the participants will also be through clinical visits social media, SMS and phone calls. Nutritional changes, physical activity amount, anxiety and stress level, abdominal circumference (AC), and body mass index (BMI) will be measured after the completion of the specified time interval. The initial outcome includes examining chemical pregnancy (2 weeks after the transmission) and clinical pregnancy by ultrasound (6 weeks after). The secondary outcome will be live birth rate. Retrieved oocyte and embryo numbers will also be reported. DISCUSSION Health-promoting lifestyle programs are essential in assisted reproductive technologies to improve pregnancy results and live birth. These programs in association with in-vitro fertilization (IVF) influence the outcome of fertilization. In addition, enhancing parental health leads to healthy pregnancy outcome. Despite the frequency of lifestyle risk factors, employing proper methods helps reduce anxiety and stress, modify dietary patterns, and perform qualitatively and quantitatively balanced physical activities. In addition, having coping skills and mental health management methods, in nowadays modern world challenges seems crucial and effective in solving fertility problems and reducing them before pregnancy.

Abstract
BACKGROUND Assisted reproductive technology (ART) has brought good news to infertile patients, but how to improve the pregnancy outcome of poor ovarian response (POR) patients is still a serious challenge and the scientific evidence of some adjuvant therapies remains controversial. AIM Based on previous evidence, the purpose of this systematic review and network meta-analysis was to evaluate the effects of DHEA, CoQ10, GH and TEAS on pregnancy outcomes in POR patients undergoing in vitro fertilization and embryo transplantation (IVF-ET). In addition, we aimed to determine the current optimal adjuvant treatment strategies for POR. METHODS PubMed, Embase, The Cochrane Library and four databases in China (CNKI, Wanfang, VIP, SinoMed) were systematically searched up to July 30, 2022, with no restrictions on language. We included randomized controlled trials (RCTs) of adjuvant treatment strategies (DHEA, CoQ10, GH and TEAS) before IVF-ET to improve pregnancy outcomes in POR patients, while the control group received a controlled ovarian stimulation (COS) regimen only. This study was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The surface under the cumulative ranking curve (SUCRA) was used to provide a pooled measure of cumulative ranking for each outcome. RESULTS Sixteen RCTs (2323 women) with POR defined using the Bologna criteria were included in the network meta-analysis. Compared with the control group, CoQ10 (OR 2.22, 95% CI: 1.05 to 4.71) and DHEA (OR 1.92, 95% CI: 1.16 to 3.16) had obvious advantages in improving the clinical pregnancy rate. CoQ10 was the best in improving the live birth rate (OR 2.36, 95% CI: 1.07 to 5.38). DHEA increased the embryo implantation rate (OR 2.80, 95%CI: 1.41 to 5.57) and the high-quality embryo rate (OR 2.01, 95% CI: 1.07 to 3.78) and number of oocytes retrieved (WMD 1.63, 95% CI: 0.34 to 2.92) showed a greater advantage, with GH in second place. Several adjuvant treatment strategies had no significant effect on reducing the cycle canceling rate compared with the control group. TEAS was the least effective of the four adjuvant treatments in most pooled results, but the overall effect appeared to be better than that of the control group. CONCLUSION Compared with COS regimen, the adjuvant use of CoQ10, DHEA and GH before IVF may have a better clinical effect on the pregnancy outcome of POR patients. TEAS needs careful consideration in improving the clinical pregnancy rate. Future large-scale RCTs with direct comparisons are needed to validate or update this conclusion.

Abstract
BACKGROUND Korea is encountering major challenges related to its declining birth rate and aging population. Various policies have been introduced to prevent further population decrease and boost the birth rate, but their effectiveness has not been verified. Therefore, this study examined the effects of assisted reproductive technology (ART) insurance coverage on marriage, pregnancy, and childbirth in women of childbearing age. METHODS All information on marriage, pregnancy, childbirth of women of childbearing age was obtained from Statistics Korea and Korean National Health Insurance Service database. During a total follow-up period of 54 months (July 2015 to December 2019), an average of 12,524,214 women of childbearing age per month, and 29,701 live births per month were included in the analysis. An interrupted time series with segmented regression was performed to analyze the time trend and changes in outcomes. RESULTS The implementation of ART coverage policies had no significant impact on marriage or pregnancy rates. However, it did affect multiple pregnancy and multiple birth rates, which increased by 1.0% (Exp(β3) = 1.010, P-value = 0.0001) and 1.4% (Exp(β3) = 1.014, P-value = < 0.0001), respectively, compared to the pre-intervention period. Although the effect of covering ART treatment on total birth rates were not confirmed, a slightly slower decline was observed after the intervention (Exp(β1) = 0.993, P-value = < 0.0001, Exp(β1 + β3) = 0.996 P-value = 0.012). CONCLUSION This study identified the effects of ART health insurance coverage policy on the rates of multiple pregnancies and births. After the policy implementation, the downward trend in the total birth rate reduced slightly. Our findings suggest that interventions to support infertile couples should be expanded to solve the problem of low fertility rates. To address the intricate problems related to low birth rates, the Korean government introduced a policy that provides financial support and health insurance coverage for assisted reproductive technology (ART) treatment for infertile couples. As a result of evaluating the effectiveness of the ART coverage policy, it led to higher rates of pregnancies and births. In addition, although the total birth rate has been continuously decreasing over time, the decline may have been slowed down slightly by this policy.

Abstract
Telomeres are repetitive DNA sequences at eukaryotic chromosome ends and function in maintaining genome integrity and stability. These unique structures undergo shortening due to various factors including biological aging, consecutive DNA replication, oxidative stress, and genotoxic agents. Shortened telomeres can be lengthened by the enzyme telomerase and alternative lengthening of telomeres in germ cells, early embryos, stem cells, and activated lymphocytes. If telomeres reach to critical length, it may lead to genomic instability, chromosome segregation defects, aneuploidy, and apoptosis. These phenotypes also occur in the oocytes and early embryos, produced using assisted reproductive technologies (ARTs). Thus, a number of studies have examined the potential effects of ART applications such as ovarian stimulation, culture conditions, and cryopreservation procedures on telomeres. Herein, we comprehensively reviewed impacts of these applications on telomere length and telomerase activity in ART-derived oocytes and embryos. Further, we discussed use of these parameters in ART centers as a biomarker in determining oocyte and embryo quality.

Abstract
RESEARCH QUESTION To explore whether prolonged hCG-ovum pickup interval improves assisted reproductive technology outcomes. DESIGN CENTRAL, CNKI, Cochrane Systematic Reviews, EMBASE, MEDLINE, PUBMED, and Web of Science up to May 13 2023 were searched for studies reporting associations between hCG-ovum pickup intervals and assisted reproductive technology outcomes. Intervention types included short (≤ 36 h) and long (> 36 h) hCG-ovum pickup intervals in assisted reproductive technology cycles. All outcomes were based upon only fresh embryo transfers. Primary outcome is defined as the clinical pregnancy rate. Data were pooled using random-effects models. Heterogeneity was assessed using the I 2 statistics. RESULTS Twelve studies were included in the meta-analysis, including five retrospective cohort studies, one prospective cohort study, and six randomized or quasi-randomized controlled trials. The short and long interval groups had similar oocyte maturation rates, fertilization rate and high-quality embryo rate (OR, 0.69; 95% CI, 0.45-1.06; I 2 = 91.1%, OR, 0.88; 95% CI, 0.77-1.0; I 2 = 44.4% and OR, 1.05; 95% CI, 0.95-1.17; I 2 = 8.6%, respectively). The clinical pregnancy rates in the long retrieval group were significantly higher than in the short retrieval group (OR, 0.66; 95% CI, 0.45-0.95; I 2 = 35.4%). The groups had similar miscarriage and live birth rates (OR, 1.92; 95% CI, 0.66-5.60; I 2 = 0.0% and OR, 0.50; 95% CI, 0.24-1.04; I 2 = 0.0%, respectively). CONCLUSIONS The clinical pregnancy rates can be increased by prolonging the hCG-ovum pickup interval, which would help us develop more reasonable time schedules for fertility centers and patients.

Abstract
Assisted reproductive technology (ART) has become common amongst couples with infertility issues. ART is known to be successful, but epidemiological data indicates that ART is associated with placental disorders. Additionally, reports show increased risks of short- and long-term complications in children born to mothers undergoing ART. However, the mechanisms responsible for these events are obscure. The placenta is considered as a key organ for programming of diseases and ART procedures are suggested to alter the placental function and intrauterine growth trajectories. Epigenetic changes in maternal and foetal tissues are suggested to be the underlying mechanisms for these outcomes. Epigenetic regulation is known to evolve following fertilisation and before implantation and subsequently across gestation. During these critical periods of epigenetic 'programming', DNA methylation and chromatin remodelling influence the placental structure and function by regulating the expression of various genes. ART treatment coinciding with epigenetic 'programming' events during gametogenesis and early embryo development may alter the programming phases leading to long-term consequences. Thus, disruptions in placental development observed in ART pregnancies could be associated with altered epigenetic regulation of vital genes in the placenta. The review summarises available literature on the influence of ART procedures on epigenetic changes in the placenta.

Abstract
Male infertility is a disease that deserves greater clinical attention and research. A universally accepted definition that emphasizes the modulatory impact of age, lifestyle and environmental factors and includes comprehensive diagnostic and treatment guidelines is needed to ensure accurate evaluation and effective care. Accordingly, male infertility should be defined as a disease of the male reproductive system, caused primarily by congenital and genetic conditions, anatomical, endocrine, functional or immunological abnormalities of the reproductive system, genital tract infections, cancer and its related treatments, and sexual disorders incompatible with intercourse. Inadequate lifestyle, exposure to toxicants and advanced paternal age are critical factors acting alone or exacerbating the impact of known causative factors. The focus on male infertility must be balanced with that on female infertility to ensure the best possible outcome for the couple. Fertility clinics are encouraged to prioritize collaboration with reproductive urologists and andrologists to provide the best possible care for male infertility patients.

Abstract
Infertility is a global health problem that carries a high social and economic burden. Assisted reproductive technology (ART) has been developed in mainland China for over 30 years. We aimed to evaluate the accessibility and equity of distribution of ART facilities in mainland China from 2006 to 2018 and quantify the population with reduced geographic access to ART services. A retrospective study was conducted to describe the trend and analyse the equity of distribution of ART clinics in 2006, 2012, and 2018. The accessibility of ART clinics in mainland China increased significantly in the 12 years to 2018 (p ˂ 0.05). Eastern China had the most extensive coverage, followed by the central region, while the western region had the least coverage (p ˂ 0.05). The Gini coefficient for the distribution of ART clinics in 2018 was 0.213, indicating that the equity of distribution of ART clinics was relatively balanced over the country. However, at the end of 2018, there were still 354.9 million people (25.4% of the population) living in 148 cities without access to any ART clinics, which has spurred more targeted policies and cost-effective measures to improve the accessibility and availability of ART services in such areas.

Abstract
The present study aimed to determine the clinical predictive significance of HIF-1α in follicular development and assisted reproductive technology (ART). We collected follicular fluid (FF) and granulosa cells (GCs) from PCOS (polycystic ovary syndrome) patients (experimental group) and other patients who were infertile due to tubal factors or male factors (control group) with IVF/ICSI-ET. The localization and expression of HIF-1α in GCs were determined by immunofluorescence staining. HIF-1α protein and mRNA expression were detected by enzyme-linked immunosorbent assay and quantitative real-time PCR, respectively. To clarify the regulation of HIF-1α by TGF-β1, we added the HIF-1α-specific blocker YC-1 to GCs. The serum AMH, LH, LH/FSH, testosterone, BMI and the number of oocytes retrieved in the PCOS group were significantly higher, while the cleavage rate was significantly lower, than those in the control group. HIF-1α protein was expressed in the cytoplasm of GCs. The expression of HIF-1α protein in the FF of the PCOS group was significantly lower than that in the control group. However, the expression of HIF-1α protein in GCs between the two groups was not significantly different. HIF-1α protein was highly expressed in large FF (follicular diameter ≥ 14 mm). Compared with the control group, the expression of HIF-1α mRNA in GCs of the PCOS group was significantly lower. The results showed a significant positive correlation between HIF-1α and TGF-β1 expression. We found that both HIF-1α and TGF-β1 were involved in the development of PCOS follicular development. The mutual regulation of HIF-1α and TGF-β1 may be one of the important mechanisms of the occurrence and development of PCOS.

Abstract
Background While elective single-embryo transfer (eSET) has been advocated in select countries, the global acceptance of the eSET policy has been undermined due to various issues. It is imperative to understand the couples' perspectives regarding the number of embryos transferred. Aims We planned a study to evaluate the knowledge and attitude of infertile couples undergoing assisted reproductive technology towards eSET in self-funded treatment cycles in a low-resource setting. Settings and Design We conducted a cross-sectional study at a tertiary-level referral facility between February 2020 and September 2022. Materials and Methods This was an interviewer-administered questionnaire-based survey in two stages. The first stage involved the assessment of the knowledge of the participants. Following this, participants were given an information pamphlet and the second stage of the interview was conducted to assess the attitude and change in preference for embryo transfer number. Statistical Analysis Used The Chi-square and Fisher's exact test were applied to find an association between categorical variables. Logistic regression was used to assess the association between factors and outcomes. Results eSET was the preferred choice for only 5.8% of the participants. Following our educational intervention using an information leaflet, there was a statistically significant increase in the preference for eSET (P = 0.01). Univariate logistic regression analysis revealed that participants with a monthly income of ≤50,000 INR had a significantly higher preference for eSET. Conclusion Continued emphasis on the risks of double-embryo transfer coupled with individualised selection criteria for eSET may help to achieve reasonable congruency between the clinician and couples' decision.
