High anti-Mullerian hormone level is adversely associated with cumulative live birth rates of two embryo transfers after the first initiated cycle in patients with polycystic ovary syndrome

High anti-Müllerian hormone level as a predictor of poor pregnancy outcomes in women with polycystic ovary syndrome undergoing in vitro fertilization/intracytoplasmic sperm injection: a retrospective cohort study

OBJECTIVE

To study the correlation between anti-Müllerian hormone levels and pregnancy outcomes after in vitro fertilization/intracytoplasmic sperm injection in women with polycystic ovary syndrome, which remains controversial.

METHODS

This retrospective cohort study recruited 4,719 women with infertility and polycystic ovary syndrome aged 20-40 years who underwent treatment at the Reproductive Center of Peking University Third Hospital between February 2017 and June 2023. We divided the participants into three groups according to the 25th and 75th percentile cutoffs of serum anti-Müllerian hormone: low (≤ 4.98 ng/mL, n = 1,198), average (4.98 - 10.65 ng/mL, n = 2,346), and high (≥ 10.65 ng/mL, n = 1,175). Pregnancy outcomes included live birth rate, miscarriage rate, clinical pregnancy rate, and cumulative live birth rate.

RESULTS

The live birth rate for fresh embryo transfer was 39.8%, 35.9%, and 30.4% in the low, average, and high anti-Müllerian hormone groups, respectively. The miscarriage rate was 11.3%, 17.1%, and 21.8% in the low, average, and high anti-Müllerian hormone groups, respectively. Significant intergroup differences were observed in the live birth rate (P = 0.017) and miscarriage rate (P = 0.018). No significant intergroup difference was observed in the clinical pregnancy rate (P = 0.204) or cumulative live birth rate (P = 0.423). After adjusting the confounders by multivariable logistic regression analysis, anti-Müllerian hormone was associated with decreased live birth rate in the high anti-Müllerian hormone group compared with that in the low anti-Müllerian hormone group (odds ratio: 0.629, 95% confidence interval: 0.460-0.860). Anti-Müllerian hormone was associated with increased miscarriage rate in the average and high anti-Müllerian hormone groups compared with that in the low anti-Müllerian hormone group (average vs. low: odds ratio: 1.592, 95% confidence interval: 1.017-2.490); high vs. low: odds ratio: 2.045, 95% confidence interval: 1.152-3.633).

CONCLUSION

High anti-Müllerian hormone is a prognostic factor for reduced live birth rate after fresh embryo transfer in women with polycystic ovary syndrome aged 20-40 years undergoing in vitro fertilization/intracytoplasmic sperm injection, and is associated with increased miscarriage rate in these patients.

Total Fertilization Failure: A Single Center Analysis

Our main objective was to identify the male and female parameters associated with total fertilization failure (TFF) in IVF with nonmasculine indications. The present work, IRB equivalent INS 63209, is a case-control study that evaluated all cases with TFF after conventional IVF at the Center for Human Reproduction from January 2010 to December 2019 (n = 154). As a control group, we analyzed all patients who did not experience fertilization failure after conventional IVF in the same period (n = 475). We evaluated various parameters, both male and female, assessed during infertility treatment, and only cases without masculine etiology (normal seminal parameters) were included. Ages (female and male) were not different between the groups. Moreover, AMH (anti-Müllerian hormone), semen volume, preprocessing concentration and preprocessing motility were not significantly different (P > 0.05). However, the number of collected oocytes (study versus control groups, median [25-75 interquartile]: 2 [1-5] and 5 [3-8]); MII (2 [1-4] and 5 [2-7]); and postprocessing motility (85 [70-90] and 90 [80-95]) were significantly different between both groups (P < 0.05). Furthermore, a logistic regression analysis including all significant data demonstrated that the number of collected oocytes was significantly related to IVF failure. Patients with fewer than 5 oocytes had an OR of - 1.37 (- 0.938 to - 1.827) for TFF after conventional IVF. Our results showed that a lower follicular response to controlled ovarian stimulation, evidenced by a decreased number of collected oocytes, was the most important parameter associated with IVF failure in nonmasculine infertility.

Higher Cumulative Live Birth Rate but Also Higher Late Miscarriage Risk in Non-Obese Women with Polycystic Ovary Syndrome Undergoing the First IVF/ICSI Cycle

Purpose

To determine the impact of polycystic ovary syndrome on in vitro fertilization/intracytoplasmic sperm injection and embryo transfer outcomes while analyzing the influencing factors.

Patients and Methods

A retrospective cohort study comprised 4839 patients who underwent their first cycle of IVF/ICSI treatment from January 2016 to December 2021. Cumulative pregnancy rates, cumulative live birth rates, and late miscarriage rates compared between the PCOS group and control group. Subgroup analysis and binary regression were used to analyze the influence of BMI on clinical outcomes among individuals diagnosed with PCOS.

Results

Non-obese PCOS patients exhibited higher cumulative pregnancy rates, cumulative live birth rates, and late miscarriage rates compared to the control group with the normal BMI population (84.7% vs71.2%, P < 0.001; 74.1% vs 61.6%, P < 0.001; 4.1% vs 2.0%, P = 0.002), but there was no significant difference in early miscarriage rates between the two groups.

Conclusion

Non-obese PCOS patients demonstrated a notably higher cumulative live birth rate but also a higher risk of late miscarriage compared to non-PCOS females with a normal BMI.

Anti-Mullerian Hormone and Fertility Treatment Decisions in Polycystic Ovary Syndrome: A Literature Review

Anti-Mullerian hormone is a robust marker of ovarian reserve and ovarian response in in vitro fertilisation (IVF). However, its role extends beyond improving the safety of IVF by aiding in choosing appropriate protocols and dosing. This review looks at the value of pre-treatment anti-Mullerian hormone (AMH) value in choosing the appropriate modality of treatment and its predictive ability for the outcomes of such treatment. It briefly addresses the factors that may modulate AMH levels and make clinical decision-making challenging.
