Implications of Progestin-Primed Ovarian Stimulation (PPOS) in a Patient With Diminished Ovarian Reserve (DOR) and Its In Vitro Fertilization (IVF) Outcome. Cureus 2024; 16:e54743. [PMID: 38523966 PMCID: PMC10960963 DOI: 10.7759/cureus.54743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 02/23/2024] [Indexed: 03/26/2024] Open
Abstract
In this case study, a 39-year-old woman pursuing treatment for secondary infertility at our infertility clinic was visited by her 42-year-old husband. The couple had a history of failed attempts, including two intrauterine insemination (IUI), two intracytoplasmic sperm injection (ICSI) cycles, and two miscarriages. Diminished ovarian reserve (DOR) was noted in the patient's medical profile. A gonadotropin-releasing hormone (GnRH) antagonist, cetrorelix acetate, was given to the patient at a daily dosage of 0.25 mg to treat their condition once the maturing follicle had grown to a diameter of 10 mm. Following the administration of the GnRH antagonist, the first oocyte pick-up (OPU) procedure was conducted. During this process, two oocytes were successfully retrieved. Subsequently, ICSI was performed to facilitate fertilization. However, during the fertilization check, it was observed that no pronuclear fertilization (PN) formations occurred, leading to a cessation of development. Following the initial failure, an ovarian stimulation strategy based on progestin priming was implemented. Progestin is administered using this technique to ready the endometrium for the implantation of the embryo. After the modified ovarian stimulation protocol, an additional beta-human chorionic gonadotropin (β-hCG) test was verified as a successful clinical pregnancy outcome.

Shen HH, Zhang XY, Liu N, Zhang YY, Wu HH, Xie F, Wang WJ, Li MQ. Chitosan alleviates ovarian aging by enhancing macrophage phagocyte-mediated tissue homeostasis. Immun Ageing 2024; 21:10. [PMID: 38279177 PMCID: PMC10821576 DOI: 10.1186/s12979-024-00412-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 01/08/2024] [Indexed: 01/28/2024]
Abstract
BACKGROUND Age-related changes in the ovarian microenvironment are linked to impaired fertility in women. Macrophages play important roles in ovarian tissue homeostasis and immune surveillance. However, the impact of aging on ovarian macrophage function and ovarian homeostasis remains poorly understood. METHODS Senescence-associated beta-galactosidase staining, immunohistochemistry, and TUNEL staining were used to assess senescence and apoptosis, respectively. Flow cytometry was employed to evaluate mitochondrial membrane potential (MMP) and apoptosis in granulosa cells lines (KGN), and macrophages phagocytosis. After a 2-month treatment with low molecular weight Chitosan (LMWC), ovarian tissues from mice were collected for comprehensive analysis. RESULTS Compared with the liver and uterus, the ovary displayed accelerated aging in an age-dependent manner, which was accompanied by elevated levels of inflammatory factors and apoptotic cells, and impaired macrophage phagocytic activity. The aged KGN cells exhibited elevated reactive oxygen species (ROS) and apoptotic levels alongside decreased MMP. H2O2-induced aging macrophages showed reduced phagocytosis function. Moreover, there were excessive aging macrophages with impaired phagocytosis in the follicular fluid of patients with diminished ovarian reserve (DOR). Notably, LMWC administration alleviated ovarian aging by enhancing macrophage phagocytosis and promoting tissue homeostasis. CONCLUSIONS Aging ovarian is characterized by an accumulation of aging and apoptotic granulosa cells, an inflammatory response and macrophage phagocytosis dysfunction. In turn, impaired phagocytosis of macrophage contributes to insufficient clearance of aging and apoptotic granulosa cells and the increased risk of DOR. Additionally, LMWC emerges as a potential therapeutic strategy for age-related ovarian dysfunction.

Abstract
OBJECTIVE This study explores the possible pathogenesis of recurrent spontaneous abortion (RSA) caused by vitamin D (VD), provides evidence-based bases for prevention and treatment of RSA, improves female reproductive health. METHODS This study randomly selected 305 patients without spontaneous abortion (SA0), 216 patients with a spontaneous abortion (SA1) and 200 patients with RSA from 1421 women of childbearing age who visited the RSA specialty clinic of Hangzhou First People's Hospital from January 2021 to June 2023 to conduct a prospective clinical study. Then, we collected the data of clinical diagnosis and treatment, conducted intervention and follow-up, and finally executed statistical analysis. RESULTS (1) RSA patients were significantly older than the other two groups. (2) The rates of VD deficiency in SA1 and RSA patients were significantly higher than those in SA0. (3) When BMI < 20 or > 24 kg/m2 , there were abnormal increase in VD and increased number of spontaneous abortions. (4) The bilateral S/D of the VD-sufficient, VD-insufficient and VD-deficient groups gradually increased with statistical significance (p ≤ .018). (5) Among the 65 cases undergoing embryo chromosome examinations, chromosomal abnormalities accounted for 55.38% and 69.05% in RSA patients. (6) Among 186 patients with abnormal ACA, there was a certain negative correlation between ACA and VD, which was stronger among RSA patients. Moreover, ACA significantly decreased (p < .001) after effectively supplementing VD, and the miscarriage rate of re-pregnancy also decreased. CONCLUSION The rate of VD deficiency is higher in RSA patients. VD deficiency may be related to the age of women of childbearing age and too low or high BMI, and may cause abnormal plasma antiphospholipid antibodies, increased uterine artery resistance and abnormal chromosomal division during fertilization, leading to spontaneous abortion and even RSA. The improvement of VD deficiency may reduce the risk of RSA occurrence.

Abstract
Background To determine whether progestin-primed ovarian stimulation (PPOS) is more effective for women with diminished ovarian reserve (DOR) than clomiphene citrate (CC)/letrozole (LE) plus gonadotropin in IVF or ICSI treatment. Methods Nine databases were searched until May 24, 2023, to identify relevant studies. Forest plots were used to present the results of this meta-analysis. Begg's and Egger's tests were applied to estimate publication bias. Subgroup and sensitivity analysis were performed to check the potential sources of heterogeneity and verify the robustness of the pooled results, respectively. Results A total of 14 studies with 4182 participants were included for meta-analysis. There was evidence of a statistically notable increase in clinical pregnancy rate (OR = 1.39, 95%CI [1.01, 1.91], p = 0.05), optimal embryos rate (OR = 1.50, 95%CI [1.20, 1.88], p = 0.0004), and cumulative pregnancy rate (OR = 1.73, 95%CI [1.14, 2.60], p = 0.009), the duration and the amount of gonadotropin required (MD = 1.56, 95%CI [0.47, 2.66], p = 0.005; SMD = 1.51, 95%CI [0.90, 2.12], p < 0.00001), along with decrease cycle cancellation rate (OR = 0.78, 95%CI [0.64, 0.95], p = 0.02), luteinizing hormone (LH) level on the day of hCG (SMD = -0.81, 95%CI [-1.10, -0.53], p < 0.00001), and premature LH surge rate (OR = 0.10, 95%CI [0.07, 0.15], p < 0.00001) when PPOS was used. No evidence for publication bias within results was revealed. Conclusions Based on evidence-based results, PPOS protocol seems to improve IVF/ICSI outcomes for women with DOR. More research with larger sample sizes and rigorous designs are required to further explore the value of PPOS among women diagnosed with DOR.

Abstract
Background Spontaneous abortion is one of the prevalent adverse reproductive outcomes, which seriously threatens maternal health around the world. Objective The current study is aimed to evaluate the association between maternal age and risk for spontaneous abortion among pregnant women in China. Methods This was a case-control study based on the China Birth Cohort, we compared 338 cases ending in spontaneous abortion with 1,352 controls resulting in normal live births. The main exposure indicator and outcome indicator were maternal age and spontaneous abortion, respectively. We used both a generalized additive model and a two-piece-wise linear model to determine the association. We further performed stratified analyses to test the robustness of the association between maternal age and spontaneous abortion in different subgroups. Results We observed a J-shaped relationship between maternal age and spontaneous abortion risk, after adjusting for multiple covariates. Further, we found that the optimal threshold age was 29.68 years old. The adjusted odds ratio (95% confidence interval) of spontaneous abortion per 1 year increase in maternal age were 0.97 (0.90–1.06) on the left side of the turning point and 1.25 (1.28–1.31) on the right side. Additionally, none of the covariates studied modified the association between maternal age and spontaneous abortion (P > 0.05). Conclusions Advanced maternal age (>30 years old) was significantly associated with increased prevalence of spontaneous abortion, supporting a J-shaped association between maternal age and spontaneous abortion.

[PMID: 35366830 PMCID: PMC8976292 DOI: 10.1186/s12884-022-04591-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 03/18/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Anti-Müllerian hormone (AMH) is used as a biomarker to estimate ovarian reserve. The relationship between AMH and early miscarriage of in vitro fertilization (IVF) is still inconclusive. This study aimed to explore whether serum AMH levels are associated with early miscarriage rates after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) with fresh embryo transfer (ET).
Methods
This retrospective cohort study included 2246 patients undergoing their first oocyte retrievals for IVF/ICSI with fresh embryos transferred to Tianjin Central Hospital of Gynecology Obstetrics between May 2018 and March 2020. The serum AMH levels of the patients were measured within 12 months before the IVF/ICSI cycles. All women were divided into a low-AMH group, medium-AMH group and high-AMH group. Binary logistic regression was applied to confirm whether the serum AMH level was associated with the risk of early miscarriage independent of potential confounders, such as age, body mass index (BMI), duration of infertility, main diagnosis, history of internal medicine diseases, number of oocytes retrieved and high-quality embryo rate.
Results
The early miscarriage rate was significantly lower in the medium-AMH group than in either the low-AMH or high-AMH group among young (< 35 years) women (P = 0.015). In women above 35 years of age, the early miscarriage rates in the three AMH groups were not significantly different. Young women with high serum AMH levels had a significantly higher risk of early miscarriage regardless of age or other potential confounders (adjusted odds ratio (OR) 2.382, 95% confidence interval (CI) 1.246 to 4.553, P = 0.009). The results remained similar after restricting the analysis to women without polycystic ovary syndrome (PCOS).
Conclusions
With a high AMH level, young women had a higher risk of early miscarriage than women with a medium AMH level in their first IVF/ICSI treatment. In young women, serum AMH levels were independently associated with the risk of early miscarriage after IVF-ET treatment. Serum AMH levels might be a valuable marker to estimate the risk of early miscarriage. It is worth noting to the clinical value of AMH.

Abstract
INTRODUCTION Women with diminished ovarian reserve (DOR) have a lower pregnancy rate and higher cancellation rate compared to those without DOR when seeking assisted reproductive technology. However, which factors are associated with reproductive outcomes and whether AMH is a predictor of clinical pregnancy remain unclear. OBJECTIVE This retrospective study was designed to find factors associated with reproductive outcomes in DOR patients and then discuss the role of AMH in predicting cycle results among this population. METHOD A total of 900 women were included in the study. They were diagnosed with DOR with the following criteria: (i) FSH > 10 IU/L; (ii)AMH < 1.1 ng/ml; and (iii) AFC <7. They were divided into different groups: firstly, based on whether they were clinically pregnant or not, pregnant group vs. non-pregnant group (comparison 1); secondly, if patients had transferrable embryos (TE) or not, TE vs. no TE group (comparison 2); thirdly, patients undergoing embryo transfer (ET) cycles were divided into pregnant I and non-pregnant I group (comparison 3). The baseline and ovarian stimulation characteristics of these women in their first IVF/ICSI cycles were analyzed. Logistic regression was performed to find factors associated with clinical pregnancy. RESULTS Of the 900 DOR patients, 138 women got pregnant in their first IVF/ICSI cycles while the rest did not. AMH was an independent predictor of TE after adjusting for confounding factors (adjusted OR:11.848, 95% CI: 6.21-22.62, P< 0.001). Further ROC (receiver operating characteristic) analysis was performed and the corresponding AUC (the area under the curve) was 0.679 (95% CI: 0.639-0.72, P< 0.001). Notably, an AMH level of 0.355 had a sensitivity of 62.6% and specificity of 65.6%. However, there was no statistical difference in AMH level in comparison 3, and multivariate logistic regression showed female age was associated with clinical pregnancy in ET cycles and women who were under 35 years old were more likely to be pregnant compared to those older than 40 years old (adjusted OR:4.755, 95% CI: 2.81-8.04, P< 0.001). CONCLUSION AMH is highly related to oocyte collection rate and TE rate,and 0.355 ng/ml was a cutoff value for the prediction of TE. For DOR patients who had an embryo transferred, AMH is not associated with clinical pregnancy while female age is an independent risk factor for it.

Abstract
Fraser syndrome is a rare autosomal recessive malformation disorder. It is characterized by cryptophthalmos, syndactyly, urinary tract abnormalities and ambiguous genitalia. This condition is due to homozygous or heterozygous mutations in the FRAS1, FREM1, FREM2, and GRIP1 genes. In the present study, we recruited a Chinese family with Fraser syndrome. Two novel mutations c.7542_7543insG and c.2689C>T in the FREM2 gene were detected in this Fraser syndrome family by PCR-based sequencing. The next-generation sequencing-based single nucleotide polymorphism haplotyping method was applied to exclude these two mutations in 9 blastocysts obtained from the patient. After obtaining consent and informing the risk, the patient received in vitro fertilization and embryo transfer treatment with an embryo carrying a heterozygous mutation. Finally, she delivered a healthy baby without any complications on March 17, 2019. In conclusion, we first reported two novel mutations in the FREM2 gene associated with the risk of Fraser syndrome. Moreover, we described a next-generation sequencing-based single nucleotide polymorphism haplotyping method to select the ‘right’ embryos from patients with Fraser syndrome for in vitro fertilization and embryo transfer treatment.
