A Successful Pregnancy Following Intracytoplasmic Sperm Injection in a Breast Cancer Survivor: A Case Report

This report documents the case of a 36-year-old female diagnosed with stage I invasive ductal carcinoma of the left breast who, alongside her 39-year-old husband, sought fertility assistance at our center due to primary infertility. Having survived cancer twice in the span of their seven-year marriage, the couple faced the challenge of overcoming both the repercussions of cancer treatment and difficulties in conceiving. Initial attempts through three intrauterine insemination (IUI) cycles proved unsuccessful, leading the couple to opt for in vitro fertilization (IVF). The fertility assessment of the husband revealed the presence of several pus cells and a high sperm DNA fragmentation index (DFI). To address this, a medication regimen was administered to improve sperm quality. Concurrently, the female underwent controlled ovarian stimulation (COS) with the anti-estrogen agent letrozole to mitigate the risk of estrogen surges that could compromise her health. Subsequently, oocytes were retrieved from the female, and intracytoplasmic sperm injection (ICSI) was used to facilitate fertilization with her husband's sperm. Following successful embryo development, the patient underwent embryo transfer (ET), resulting in a positive beta-human chorionic gonadotropin (beta-hCG) result, signifying a successful conception. This case report highlights the intricate challenges faced by individuals with a history of breast cancer, emphasizing the delicate balance required in managing infertility in such circumstances. The described approach, involving personalized treatments and meticulous care, underscores the possibility of achieving successful conception for females struggling with fertility issues post-cancer survival. The documented journey serves as a testament to the resilience of individuals facing the dual challenges of cancer survival and infertility, offering insights into the complexities of their reproductive healthcare.

A Comprehensive Approach to Polycystic Ovarian Syndrome: A Case Report of Successful Intracytoplasmic Sperm Injection Treatment Utilizing the Short Antagonist Protocol and Hatching

The 29-year-old participant in the case study has been grappling with infertility for the last six years. Following an assessment of her symptoms, hormone profile, and ultrasound results, she received a diagnosis of polycystic ovarian syndrome (PCOS). PCOS is a multifaceted endocrine and metabolic disorder characterized by symptoms such as obesity, insulin resistance, anovulation, and polycystic ovaries. Various factors, including heredity, intestinal dysbiosis, obesity, environmental pollutants, lifestyle choices, and neuroendocrine abnormalities, contribute to the susceptibility of women to PCOS. In planning polycystic ovarian stimulation, it is crucial to consider parameters such as antral follicle count (AFC), luteinizing hormone (LH), and anti-Müllerian hormone (AMH). Careful planning of the gonadotrophin dose is essential to achieve an optimal response during a gonadotropin-releasing hormone antagonist (GnRH-ant) cycle. In our case, the brief antagonist protocol was used, resulting in a favorable outcome with minimal risk of ovarian hyperstimulation syndrome (OHSS). Despite multiple unsuccessful attempts at natural conception, the patient successfully conceived with the help of intracytoplasmic sperm injection (ICSI), leading to a positive pregnancy outcome. In addition to incorporating mechanical hatching to promote implantation, we diligently selected the most beneficial medications for the patient.

25 years after Dolly: Update on long-term effects of embryo biotechnologies

Since the announcement of the birth of Dolly, the world's first mammal produced by cloning, it was demonstrated for the first time that somatic cells could be reprogrammed to produce a whole individual. This represented a considerable change in paradigm in the field of embryo technologies both in humans and animals which led to an intense burst of research on nuclear transfer but also on the establishment of pluripotency and the directed edition of the genome. As such, induced pluripotent cells and gene editing tools, the best known being CRISPR-Cas9, are now available to the scientific community. Nevertheless, cloning was associated with important developmental abnormalities in a variable proportion of pregnancies, raising concern about the long-term effects of embryo technologies at a time when the concept of the developmental origins of health and disease had emerged, together with a better understanding of the underlying epigenetic modifications. The focus of this article is to review current knowledge on long-term effects of artificial reproduction technologies in mammals, leading to globally reassuring information although differences are present and caution remains necessary taking the current increasing number of in vitro-produced ruminant and equine embryos into account and their potential intergenerational consequences.

Short Ejaculatory Abstinence in Normozoospermic Men is Associated with Higher Clinical Pregnancy Rates in Sub-fertile Couples Undergoing Intra-Cytoplasmic Sperm Injection in Assisted Reproductive Technology: A Retrospective Analysis of 1691 Cycles

BACKGROUND

The current WHO abstinence recommendations are ideal only for clinical diagnosis, as in recent years a negative correlation of abstinence duration with good embryo development and clinical pregnancy rate has been seen.

AIM

The aim of the study was to evaluate the impact of variation in abstinence period on fertilization, embryo development potential, pregnancy, and miscarriage rate in sub-fertile couples undergoing assisted reproductive technology (ART) treatment.

SETTING AND DESIGN

A prospective analysis was conducted at a tertiary (level 3) infertility care clinic.

MATERIALS AND METHODS

The study included analysis of 1691 cycles for the patient undergoing ART procedures between September 2017 and August 2019. The influence of ejaculatory abstinence (EA) was investigated based on variation in abstinence length with four groups: Group I - 1 day; Group II - 2-5 days; Group III - 6-7 days; and Group IV - EA length of ≥8 days.

STATISTICAL ANALYSIS

Analysis of variance and Chi-square test were used to calculate P value.

RESULTS

In our primary outcome, we have seen a strong positive correlation of abstinence duration with semen volume, total sperm count, total motile count, and difference between each group was significant. Secondary outcomes showed a significantly higher implantation rate, biochemical pregnancy rate was observed in Group I (1 day) per embryo transfer as compared to longer abstinence groups. This resulted in significantly higher clinical pregnancy rates in Group I 30.0% vs. 25.4% in comparison to longer abstinence groups.

CONCLUSIONS

Our study has shown duration of abstinence is negatively correlated with positive β-human chorionic gonadotropin rate, clinical pregnancy rate, and implantation rate. Lower miscarriage rate was also observed with shorter abstinence duration.

Association between TSH Level and Pregnancy Outcomes in Euthyroid Women Undergoing IVF/ICSI: A Retrospective Study and Meta-analysis

The aim of this study was to determine the association between thyroid-stimulating hormone (TSH) level and pregnancy outcomes in euthyroid women undergoing in vitro fertilization (IVF)/intra-cytoplasmic sperm injection (ICSI). A total of 1185 women were enrolled in the retrospective study, and 12 studies with a total of 6624 women were included in the meta-analysis (including the data of the present retrospective study). Participants in the retrospective study were divided into two groups in terms of their serum TSH levels: TSH ≤2.5 mIU/L group (n=830) and TSH >2.5 mIU/L group (n=355). They were monitored for the status of clinical pregnancy or miscarriage. In the TSH ≤2.5 mIU/L group, 441 (53.1%) women achieved clinical pregnancy, while 48 (5.8%) had early pregnancy loss and 12 (1.4%) had ectopic pregnancy. In the TSH >2.5 mIU/L group, 175 (49.3%) women achieved clinical pregnancy, while 21 (5.9%) had early pregnancy loss and 3 (0.8%) had ectopic pregnancy. No significant differences were observed between the two groups in pregnancy outcomes (P=0.126, P=0.512, P=0.297). The meta-analysis also revealed no significant difference in the clinical pregnancy rate and the miscarriage rate between women with serum TSH ≤2.5 mIU/L and those with serum TSH >2.5 mIU/L. In conclusion, high TSH levels (TSH level >2.5 mIU/L) did not affect clinical pregnancy rate or increase miscarriage rate in euthyroid women undergoing IVF/ICSI.

The influence of obesity, smoking, and serum follicular stimulating hormone in azoospermic patients on testicular sperm extraction-intra cytoplasmic sperm injection outcomes: A retrospective cohort study

To examine the effect of serum follicle-stimulating hormone (sFSH) level, body-mass index (BMI) and smoking on Testicular Sperm Extraction-Intracytoplasmic Sperm Injection (TESE-ICSI), and pregnancy outcomes.In this retrospective study, data were extracted from files of 52 azoospermic men who underwent TESE and in-vitro fertilization (IVF)-ICSI in our IVF unit. Demographic information, treatment cycle follow-up and pregnancy outcomes were collected.Fifty-two patients underwent 79 TESE due to azoospermia in 143 IVF cycles. Smoking was found to significantly affect sperm motility in TESE specimens before freezing (45.5% vs 14.8%; P <.001); however, this finding did not influence the pregnancy rate. Male FSH was inversely correlated with testicle volume (r = -0.595, P <.0001). Body weight did not affect semen parameters after TESE or ICSI outcomes.Among azoospermic patients with extremely poor sperm quality, male BMI, male FSH or smoking did not have an adverse effect sperm parameters or pregnancy and delivery rates.

Social stigma and familial attitudes related to infertility

Objective:

To determine the perceived social stigma and familial attitides and perception of sexuality in infertile couples attending infertility clinics.

Materials and Methods:

Infertile couples attending infertility clinics between the years of 2014 and 2015 were requested to complete detailed evaluation forms including questions related to the social stigma on their infertility, their familial attitudes, and perception of sexuality. Any partner of the infertile couple accepting to enroll in the study was given the evaluation forms. Their scores related to answers and demographics, and parameters related to infertility were analyzed.

Results:

A total 598 partners of infertile couples enrolled in the study, 58% represented 177 couples. Their infertility was primary in 98.3% and the duration of marriage and infertility was 9.81±5.58 and 9.76±5.53 years, respectively. The perception of social exclusion was present in 38% (p<0.001) of infertile couple, which was more significantly pronounced in female partners (p=0.013). Fifteen percent of the infertile couples thought themselves as isolated in public and losing value in public (p<0.001). However, sixty percent of infertile couples thought that they would achieve a notable place in community after having a baby (p<0.001). Infertility was accepted as a reason of divorce in only 13% of infertile couples (p<0.001). The majority of perticipnats, irrespective of sex, rejected that infertile women or men lost sexual appeal (86%; p<0.001).

Conclusions:

There is significant effect of infertility on familial attitudes and perception of sexuality of infertile couples. Unfortunately, there is significant negative social stigma on infertile couples.

Sperm recovery and ICSI outcomes in Klinefelter syndrome: a systematic review and meta-analysis

BACKGROUND

Specific factors underlying successful surgical sperm retrieval rates (SRR) or pregnancy rates (PR) after testicular sperm extraction (TESE) in adult patients with Klinefelter syndrome (KS) have not been completely clarified.

OBJECTIVE AND RATIONALE

The aim of this review was to meta-analyse the currently available data from subjects with KS regarding SRRs as the primary outcome. In addition, when available, PRs and live birth rates (LBRs) after the ICSI technique were also investigated as secondary outcomes.

SEARCH METHODS

An extensive Medline, Embase and Cochrane search was performed. All trials reporting SRR for conventional-TESE (cTESE) or micro-TESE (mTESE) and its specific determinants without any arbitrary restriction were included.

OUTCOMES

Out of 139 studies, 37 trials were included in the study, enrolling a total of 1248 patients with a mean age of 30.9 ± 5.6 years. The majority of the studies (n = 18) applied mTESE, 13 applied cTESE and in one case testicular sperm aspiration (TESA) was used. Additionally, four studies used a mixed approach and in one study, the method applied for sperm retrieval was not specified. Overall, a SRR per TESE cycle of 44[39;48]% was detected. Similar results were observed when mTESE was compared to cTESE (SRR 43[35;50]% vs 45[38;52]% for cTESE vs micro-TESE, respectively; Q = 0.20, P = 0.65). Meta-regression analysis showed that none of the parameters tested, including age, testis volume and FSH, LH and testosterone (T) levels at enrollment, affected the final SRR. Similarly, no difference was observed when a bilateral procedure was compared to a unilateral approach. No sufficient data were available to evaluate the effect of previous T treatment on SRR. Information on fertility outcome after ICSI was available for 29 studies. Overall a total of 218 biochemical pregnancies after 410 ICSI cycles were observed (PR = 43[36;50]%). Similar results were observed when LBR was analyzed (LBR = 43[34;53]%). Similar to what was observed for SRR, no influence of KS age, mean testis volume, LH, FSH or total T levels on either PR and LBR was observed. No sufficient data were available to test the effect of the women's age or other female fertility problems on PR and LBR. Finally, no difference in PR or LBR was observed when the use of fresh sperm was compared to the utilization of cryopreserved sperm.

WIDER IMPLICATIONS

The present data suggest that performing TESE/micro-TESE in subjects with KS results in SRRs of close to 50%, and then PRs and LBRs of close to 50%, with the results being independent of any clinical or biochemical parameters tested.

Can AMH levels predict the need for increased medication during IVF/ICSI in PCOS women?

PURPOSE

To investigate the ability of anti-Mullerian hormone (AMH) to predict the step up of human menopausal gonadotropins (HMG) dose in women with polycystic ovarian syndrome (PCOS) undergoing IVF/ICSI cycles.

METHODS

AMH was drawn before ovulation induction in 976 PCOS women scheduled for IVF/ICSI. After all cycles ended, a receiver operating characteristic (ROC) curve analysis was done to investigate the ability of AMH to predict step up of the HMG.

RESULTS

The area under the curve (AUC) was 0.820 95%CI (0.792-0.848), and a cutoff value of 4.6 ng/ml (sensitivity 74%, specificity 82%) for AMH was taken (p < 0.01). Cases were divided into two groups retrospectively; group (A) (AMH ≤4.6 ng/ml), and group (B) (AMH >4.6 ng/ml). No difference in the mean age (p = 0.147); BMI (p = 0.411), basal FSH (p = 0.221), and starting dose (p = 0.195); however, the dose at which the first response occurred was higher in group (B) (p < 0.01). The total dose and number of days were higher in group (B) (both p < 0.01) irrespective of the PCOS subtype or androgen levels. Severe OHSS was also higher in group (B) (p = 0.026).

CONCLUSIONS

PCOS with AMH >4.6 ng/ml are resistant to HMG stimulation, require dose step up during ART cycles, and are at higher risk for severe OHSS.

An update on the prevention of ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome is a potentially life-threatening, but preventable iatrogenic complication of in vitro fertilisation treatment. In recent years, new strategies have been developed to minimise the risk of ovarian hyperstimulation syndrome after in vitro fertilisation, including better at-risk patient identification prior to starting treatment, the use of a lower human chorionic gonadotrophin dose or alternative medication instead of human chorionic gonadotrophin to induce final oocyte maturation such as gonadotrophin-releasing hormone agonist and kisspeptin in antagonist cycles, cryopreservation of all embryos and delayed embryo transfer, and the use of oral dopamine agonists after oocyte retrieval. In this article, the advantages and limitations of those new developments are discussed and future directions towards establishment of an ovarian hyperstimulation syndrome-free in vitro fertilisation clinic are explored.

Testicular versus ejaculated spermatozoa in ICSI cycles of normozoospermic men with high sperm DNA fragmentation and previous ART failures

As a part of male assessment, conventional sperm parameters including morphologic features have been dedicated as major factors influencing fertilisation and pregnancy rates in assisted reproductive technology (ART). Genomic integrity of spermatozoa has also been found to influence fertility prognosis, and hence, sperm DNA fragmentation index (DFI) has been adopted by many centres to document this entity. Despite several suggested approaches, there is lack of universal consensus on optimising fertility outcomes in males with high sperm DFI. In this context, the results from cycles using testicular spermatozoa (TESA) obtained by aspiration were compared with those of ejaculated spermatozoa (EJ) in normozoospermic subjects with high sperm DFI and previous ART failures. Clinical (41.9% versus 20%) and ongoing pregnancy rates (38.7% versus 15%) were significantly better and miscarriages were lower in TESA group when compared to EJ group. Sperm DFI should be a part of male partner's evaluation following unsuccessful ART attempts. When high DFI is detected (>30%), ICSI using testicular spermatozoa obtained by TESA seems an effective option particularly for those with repeated ART failures in terms of clinical, ongoing pregnancies and miscarriages even though conventional sperm parameters are within normal range.

A comparative study between cleavage stage embryo transfer at day 3 and blastocyst stage transfer at day 5 in in-vitro fertilization/intra-cytoplasmic sperm injection on clinical pregnancy rates

OBJECTIVE

To evaluate the efficacy of blastocyst transfer in comparison with cleavage stage transfer.

STUDY DESIGN

A randomized, prospective study was conducted in Infertility clinic, Department of Obstetrics and Gynecology, Mahatma Gandhi Hospital, Jaipur on 300 patients aged 25-40 years undergoing in-vitro fertilization (IVF)/intra-cytoplasmic sperm injection (ICSI) cycle from May 2010-April 2011. When three or more Grade-I embryos were observed on day 2 of culture, patients were divided randomly into two study groups, cleavage stage transfer and blastocyst transfer group having 150 patients each. Primary outcomes evaluated were, Clinical pregnancy rate and Implantation rate. The results were analyzed using proportions, standard deviation and Chi-square test.

RESULTS

Both the groups were similar for age, indication and number of embryos transferred. Clinical pregnancies after blastocyst transfer were significantly higher 66 (44.0%) compared to cleavage stage embryo transfer 44 (29.33%) (P < 0.01). Implantation rate for blastocyst transfer group was also significantly higher (P < 0.001).

CONCLUSION

Blastocyst transfer having higher implantation rate and clinical pregnancy rate lead to reduction in multiple pregnancies.

Total fertilization failure in intra-cytoplasmic sperm injection cycles--classification and management

In this retrospective cohort study we intended to propose a classification and preliminary management strategy for couples exhibiting total fertilization failure (TFF) in intra-cytoplasmic sperm injection (ICSI) cycles. Sixteen couples with a total of 27 cycles exhibiting TFF, age <40 and/or more than four M2 oocytes aspirated were enrolled. While TFF occurred in 4.3% of all 3723 ICSI cycles, in women younger than 40 with at least 5 M2 oocytes the TFF rate was 0.7%. Indications for ICSI were severe male factor and unexplained infertility. Of the 16 couples with TFF, 4 demonstrated a single episode of TFF, with either subsequent or former normal fertilizations, thus implying possible sporadic faulty laboratory conditions. Ten couples demonstrated repeated total or very low fertilization rates, hinting at a gamete defect not overcome by ICSI. Two couples experienced TFF in the first and only cycle performed at our unit. We conclude that initial and repeated TFF hints at severe gamete defects for which only donor gametes may prove successful while sporadic TFF events could simply imply a technical modifiable condition.
