Correlation of serum Anti-Müllerian hormone concentrations on day 3 of the in vitro fertilization stimulation cycle with assisted reproduction outcome in polycystic ovary syndrome patients

Optimal antimüllerian hormone levels in oocyte donors: a national database analysis

OBJECTIVE

To study the relationship between high antimüllerian hormone (AMH) levels in oocyte donors and embryo development and pregnancy outcomes among donor oocyte recipients.

DESIGN

Retrospective cohort study.

SETTING

Donor Egg Bank Database.

PATIENTS

Patients undergoing in vitro fertilization using vitrified donor oocytes from 35 in vitro fertilization centers in the United States between 2013 and 2021. For each recipient, the first oocyte lot that was received with a planned insemination and embryo transfer (ET) was included.

INTERVENTION

Oocyte donor-recipient cycles.

MAIN OUTCOME MEASURES

Ongoing pregnancy rate (OPR) per ET.

RESULTS

A total of 3,871 donor oocyte-recipient thaw cycles were analyzed. On the basis of donor AMH serum concentration, cycles were stratified into the high AMH group (AMH ≥5 ng/mL; n = 1,821) and the referent group (AMH <5 ng/mL; n = 2,050). Generalized estimating equation models were used to account for donors that contributed more than one lot of oocytes. The number of usable embryos per lot (median [interquartile range]) was significantly increased in the high AMH group (2 [2-4]) compared with the referent group (2 [1-3]) (relative risk [RR] 1.06; confidence interval [CI] 1.01-1.12). Among recipients with a planned ET, there was no difference in OPR between the high AMH group (45.4%) and the referent group (43.5%) (RR 1.04; 95% CI 0.94-1.15). Among preimplantation genetic testing for aneuploidy cycles, the embryo euploidy rate per biopsy was similar at 66.7% (50%-100%) in both groups (RR 1.04; CI 0.92-1.17). The OPR per euploid ET among patients who used preimplantation genetic testing for aneuploidy was also comparable, at 52% in the high AMH group and 54.1% in the referent group (RR 0.95; CI 0.74-1.23).

CONCLUSION

This large national database study observed that there was no association between a high level of AMH (≥5 ng/mL) in oocyte donors and an OPR in the recipient after the first ET. On the basis of these findings, recipients and physicians can be reassured that oocyte donors with a high AMH level can be expected to produce outcomes that are at least as good as donors with an AMH level (<5 ng/mL).

Elevated Anti-Müllerian Hormone as a Prognostic Factor for Poor Outcomes of In Vitro Fertilization in Women with Polycystic Ovary Syndrome

Women with polycystic ovary syndrome (PCOS) tend to have elevated anti-Müllerian hormone (AMH) levels, which appear to correlate with disease severity and pregnancy outcomes. This was a retrospective observational study designed to assess the relationship between circulating AMH levels and in vitro fertilization (IVF) outcomes. The study involved 150 women with PCOS who underwent IVF treatments. The women's IVF cycles were allocated into three subgroups according to AMH levels: 'low' (AMH < 3.7 ng/mL; n = 49), 'middle' (AMH 3.7-7.4 ng/mL; n = 94), and 'high' (AMH > 7.4 ng/mL; n = 56). All pregnancy-related outcomes (positive beta human chorionic gonadotropin (βHCG), clinical pregnancy rate, live birth rate, and cumulative live birth rate) were greater in women's IVF cycles with 'low' AMH when compared to those with 'middle' or 'high' AMH (p < 0.05). AMH levels below 3.7 ng/mL were found to be associated with lower oocyte immaturity rate and better pregnancy outcomes, although baseline AMH was not shown to have any significant predictive power for live birth and cumulative live birth in the multivariable logistic regression analysis after adjusting for possible confounders nor in the ROC analyses. In summary, the current study lays the groundwork to validate high AMH levels as a poor prognostic factor for pregnancy outcomes after IVF in women with PCOS.

Association between serum AMH levels and IVF/ICSI outcomes in patients with polycystic ovary syndrome: a systematic review and meta-analysis

CONTEXT

Anti-Müllerian hormone (AMH) levels are increased in polycystic ovary syndrome (PCOS) patients and are associated with PCOS severity.

OBJECTIVE

To evaluate the associations between serum AMH levels and in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) outcomes in patients with PCOS.

DATA SOURCES

PubMed, Embase, and the Cochrane Library were searched on 11 July 2022.

STUDY SELECTION

Studies reporting the association between serum AMH levels and IVF/ICSI outcomes in PCOS patients were considered for inclusion. The primary outcomes were clinical pregnancy, live birth, and ovarian hyperstimulation syndrome.

DATA EXTRACTION

Data were extracted using a standardized data extraction form. Study quality was assessed independently by two groups of researchers.

DATA SYNTHESIS

Nineteen studies were included in this review. Meta-analyses demonstrated that PCOS patients with a serum AMH level within the 75-100th percentile had a decreased odds of clinical pregnancy (OR: 0.77, 95% CI: 0.63-0.93) and livebirth (OR: 0.71; 95% CI: 0.58-0.87) compared to those within the 0-25th percentile. An increased AMH level was also correlated with an increased number of oocytes retrieved (SMD: 0.90, 95% CI: 0.30-1.51) and a lower odds of fertilization (OR: 0.92, 95% CI: 0.87-0.98). There was no significant difference in the number of MII oocytes (SMD: 1.85, 95% CI: -1.07-4.78), E2 on the day of hCG (SMD: 0.12; 95% CI: -0.98-1.23), or implantation (OR: 0.82, 95% CI: 0.28-2.39) between the two groups. In addition, we found significant dose-response associations between serum AMH level and clinical pregnancy, live birth, number of oocytes retrieved, and fertilization in PCOS patients.

CONCLUSION

AMH may have clinical utility in counseling regarding IVF/ICSI outcomes among women with PCOS who wish to undergo fertility treatment. More large-scale, high-quality cohort studies are needed to confirm these findings.

Serum levels of anti-Müllerian hormone influence pregnancy outcomes associated with gonadotropin-releasing hormone antagonist treatment: a retrospective cohort study

As a specific predictor of ovarian reserve, serum anti-Müllerian hormone (AMH) has become an area of intense research interest in the field of assisted reproductive technology. We assessed the relationship between AMH levels and pregnancy outcomes in Chinese patients and investigate the influencing factors of cumulative live birth in patients with high AMH levels. A total of 1379 patients starting their IVF/ICSI cycle were divided into normal (Group A, 1.1-4.0 ng/ml, n = 639) and high (Group B, > 4.0 ng/ml, n = 740) groups by serum AMH levels. Live birth rate (LBR), cumulative live birth rate (CLBR) and cumulative clinical pregnancy rate (CCPR) were also investigated. Compared with Group A, Group B had a significantly higher CLBR (65.80% vs. 43.95%) and CCPR (76.77% vs. 57.14%), respectively. Binomial logistic regression analysis showed that age over 40 years, LH/FSH > 2.5, total Gn dose and Gn duration, and greater than 4000 ng/ml serum E2 levels on HCG day were significantly associated with CLBR in Group B. The AUC value of CLBR averaged 0.664 (ranging from 0.621 to 0.706) (p < 0.001). The patients with high AMH levels had higher CPR, higher LBR, and lower MR with no statistically significant differences, although there were significant improvements in CLBR. Advanced age (> 40 years) still impacted CLBR, even in women with good ovarian reserves. Consequently, it is still recommended that patients over 40 years old with high AMH levels actively receive IVF treatment if they seek to become pregnant. PCOS diagnoses did not influence the CLBR. In summary, this study showed that serum AMH levels could positively predict patient ovarian responses and further affect pregnancy outcomes.

Analysis of cumulative outcomes and influencing factors of patients with discrepancies between age and AMH levels in the early follicular phase prolonged protocol

OBJECTIVE

To explore the cumulative outcomes and influencing factors of patients with discrepancies between age and Anti-Müllerian hormone (AMH) levels in the early follicular phase prolonged protocol.

METHODS

A total of 1282 cycles of in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) assisted pregnancy with the early follicular phase prolonged protocol in the Reproductive Medicine Center of the Third Affiliated Hospital of Zhengzhou University from September 2015 to December 2020 were retrospectively analyzed. They were divided into the young low-AMH group (n=1076) and the older high-AMH group (n=206). The primary outcomes included cumulative clinical pregnancy rate (CCPR) and cumulative live birth rate (CLBR). Secondary outcomes included the number of oocytes retrieved, number of available embryos, clinical pregnancy rate (CPR), live birth rate (LBR), miscarriage rate (MR), pregnancy complications, and neonatal outcomes.

RESULTS

The CPR (68.7% vs. 59.4%) and the LBR (60.7% vs. 43.1%) in the young low-AMH group were higher than those in the older high-AMH group. In contrast, the number of oocytes retrieved (11 vs. 17), number of available embryos (5 vs. 8), and MR (10.6% vs. 18.3%) in the young low-AMH group were lower. There was no significant difference between the two groups in the CCPR, CLBR, pregnancy complications, and neonatal outcomes. Logistic regression analysis showed that infertility duration, basal follicle-stimulating hormone (FSH), and antral follicle count (AFC) correlated with CCPR, while maternal age, type of infertility, basal FSH, AFC, and infertility duration correlated with CLBR. The area under the receiver operating characteristic curves (ROC) curve for the combined model of infertility duration, AFC, and basal FSH to predict cumulative pregnancy was 0.629 (95%CI:0.592-0.666), while the combined model of maternal age, AFC, basal FSH, infertility duration, and type of infertility to predict cumulative live birth was 0.649 (95%CI:0.615-0.682).

CONCLUSION

Although AMH levels are low by contrast, young patients have a favorable outcome after IVF/ICSI. In patients with discrepancies between age and AMH levels in the early follicular phase prolonged protocol, maternal age correlates better with cumulative live birth. The model that combines maternal age and other factors can help predict cumulative live birth, but its value is limited.

The Impact of High Circulating Anti-Müllerian Hormone on Endometrial Thickness and Outcome of Assisted Reproductive Technology in Women with Polycystic Ovarian Syndrome: A Cohort Study

Background

Elevated circulating anti-Müllerian hormone (AMH) in women with the polycystic ovarian syndrome (PCOS) has been found to have a detrimental effect on endometrial function. This may adversely affect the outcome of in vitro fertilisation (IVF) in PCOS women.

Aims

To investigate the impact of high serum AMH concentrations on endometrial thickness (ET) and the outcome of IVF in women with PCOS.

Settings and Design

This retrospective cohort study included all PCOS women who underwent fresh IVF\intracytoplasmic sperm injection cycles between January 2016 and December 2021 in one major IVF centre.

Materials and Methods

PCOS diagnosis was based on Rotterdam criteria, and participants were identified from centre database. All women received antagonist protocol. Primary outcomes were trigger-day ET and live birth rate (LBR). Circulating AMH was correlated with ET and ovarian response.

Statistical Analysis Used

AMH levels were compared between women with and without live birth. ET and LBRs were compared between women with AMH <7.0 ng/ml versus those with AMH ≥7.0 ng/ml.

Results

The study included 102 PCOS women, of which six were excluded due to poor response (n = 4), hyperresponse (n = 1) or fertilisation failure (n = 1). Of the remaining 96 women, 42 (43.8%) achieved a live birth. There was no statistically significant (P > 0.05) correlation between AMH and ET. Mean ± standard deviation AMH concentration was not significantly (P > 0.05) different between women with live birth (6.5 ± 3.4 ng/ml) and those without (6.5 ± 2.4 ng/ml). High AMH positively correlated with the number of oocytes retrieved, metaphase II oocytes and embryos (P = 0.003, 0.006 and 0.006, respectively). There was no statistically significant (P > 0.05) difference in ET or LBR between women with AMH <7.0 ng/ml (n = 72; ET, 10.7 ± 1.8 mm; LBR, 45.8% [33/72] versus those with AMH ≥7.0 ng/ml (n = 24; ET, 10.8 ± 1.7 mm; LBR, 37.5% [9/24]).

Conclusions

High circulating AMH in PCOS women does not seem to negatively affect ET or LBRs during assisted reproductive technology.

Impact of increasing antimüllerian hormone level on in vitro fertilization fresh transfer and live birth rate

Objective

The objective of our study was to assess the association between AMH and live birth among women with elevated AMH undergoing first fresh IVF. Serum antimüllerian hormone (AMH) correlates with oocyte yield during in vitro fertilization (IVF). However, there are limited data regarding IVF outcomes in women with elevated AMH levels.

Design

Retrospective cohort study using the Society for Assisted Reproductive Technology Clinical Outcomes Reporting System database from 2012-2014.

Setting

Fertility clinics reporting to Society for Assisted Reproductive Technology.

Patients

First, fresh, autologous IVF cycles with elevated AMH levels (≥5.0 ng/mL). Subanalyses were performed to examine patients with or without polycystic ovary syndrome (PCOS).

Interventions

None.

Main Outcome Measures

Odds of live birth.

Results

Our cohort included 10,615 patients with elevated an AMH level, including 2,707 patients with PCOS only. The adjusted odds of live birth per initiated cycle were significantly lower per each unit increase in the AMH level (odds ratio, 0.97; 95% confidence interval, 0.96-0.98). Increasing AMH level was associated with increased cancellation of fresh transfer (odds ratio, 1.12; 95% confidence interval, 1.10-1.15) up to an AMH level of 12 ng/mL. The decrease in the live birth rate appears to be caused by the increasing incidence of cancellation of fresh transfer because the live birth rate per completed transfer was maintained. Similar trends were observed in the PCOS and non-PCOS subanalyses.

Conclusions

Among patients with AMH levels of ≥5 ng/mL undergoing fresh, autologous IVF, each unit increase in AMH level is associated with a 3% decrease in odds of live birth because of the increased incidence of fresh embryo transfer cancellation.

Cumulative live birth rate after ovarian stimulation with freeze-all in women with polycystic ovaries: does the polycystic ovary syndrome phenotype have an impact?

RESEARCH QUESTION

Do cumulative live birth rates (CLBR) differ between polycystic ovary syndrome (PCOS) phenotypes when a freeze-all strategy is used to prevent OHSS after ovarian stimulation?

DESIGN

A single-centre, retrospective cohort study of 422 women with PCOS or polycystic ovarian morphology (PCOM), in whom a freeze-all strategy was applied after GnRH agonist triggering because of hyper-response in their first or second IVF/ICSI. Primary outcome was CLBR; multivariate logistic regression analysis was used.

RESULTS

Phenotype A (hyperandrogenism + ovulation disorder + PCOM [HOP]) (n = 91/422 [21.6%]); phenotype C (hyperandrogenism + PCOM [HP]) (33/422 [7.8%]; phenotype D (ovulation disorder + PCOM [OP]) (n = 161/422 [38.2%]); and PCOM (n = 137/422 [32.5%]. Unadjusted CLBR was similar among the groups (69.2%, 69.7%, 79.5% and 67.9%, respectively; P = 0.11). According to multivariate logistic regression analysis, the phenotype did not affect CLBR (OR 0.72, CI 0.24 to 2.14 [phenotype C]; OR 1.55, CI 0.71 to 3.36 [phenotype D]; OR 0.84, CI 0.39 to 1.83 [PCOM]; P = 0.2, with phenotype A as reference).

CONCLUSIONS

In women with PCOS, hyper-response after ovarian stimulation confers CLBR of around 70%, irrespective of phenotype, when a freeze-all strategy is used. This contrasts with unfavourable clinical outcomes in women with hyperandrogenism and women with PCOS who underwent mild ovarian stimulation targeting normal ovarian response and fresh embryo transfer. The results should be interpreted with caution because the study is retrospective and cannot be generalized to all cycles as they pertain to those in which hyper-response is observed.

AMH Highly Correlates With Cumulative Live Birth Rate in Women with Diminished Ovarian Reserve Independent of Age

CONTEXT

Antimüllerian hormone (AMH) level is strongly associated with ovarian response in assisted reproductive technology (ART) cycles but is a poor predictor of live birth. It is unknown whether AMH is associated with cumulative live birth rates (CLBRs) in women with diminished ovarian reserve (DOR).

OBJECTIVE

To examine the association between serum AMH and CLBR among women with DOR undergoing ART.

METHODS

Retrospective analysis of Society for Assisted Reproductive Technology Clinic Outcome Reporting System database 2014-16. A total of 34 540 index retrieval cycles of women with AMH <1 ng/mL. The main outcome measure was cumulative live birth.

RESULTS

A total of 34 540 (25.9%) cycles with AMH <1 ng/mL out of 133 442 autologous index retrieval cycles were analyzed. Cycles with preimplantation genetic testing or egg/embryo banking were excluded. Data were stratified according to AMH and, age and regression analysis of AMH and CLBR was performed for each age stratum. Multiple logistic regression demonstrated that AMH is an independent predictor of CLBR (odds ratio [OR] 1.39, 95% CI 1.18-1.64). Serum AMH was strongly associated with number of oocytes retrieved, embryos cryopreserved, mean number of cumulative embryos transferred, and percentage of cycles that had an embryo transfer. Linear regression analysis demonstrated that AMH highly correlated with CLBR in each age stratum.

CONCLUSION

Serum AMH is highly correlated with CLBR in women with DOR independent of age. The addition of AMH to current age-based prognostication counseling particularly in women with DOR would provide more informative and personalized CLBR prediction prior to ART.

High Serum Anti-Müllerian Hormone Concentrations Are Associated With Poor Pregnancy Outcome in Fresh IVF/ICSI Cycle but Not Cumulative Live Birth Rate in PCOS Patients

OBJECTIVE

To investigate the association between baseline serum Anti-Müllerian hormone (AMH) levels and IVF/ICSI outcomes in women with polycystic ovary syndrome (PCOS).

DESIGN

Retrospective study.

SETTING

Reproductive medicine center in a hospital.

POPULATION

2436 PCOS patients (Rotterdam criteria) who underwent their first fresh IVF/ICSI cycles were divided into three groups on the basis of the <25th (Group 1, n=611), 25 to 75th (Group 2, n=1216), or >75th (Group 3, n=609) percentile of baseline serum AMH level.

INTERVENTIONS

Baseline serum AMH levels measured on the 2-3 days of spontaneous menstrual cycle before IVF/ICSI treatment.

MAIN OUTCOME MEASURES

Live birth rate (LBR), cumulative live birth rate (CLBR), clinical pregnancy rate (CPR), and normal fertilization rate (FR).

RESULTS

The LBR, CPR, and FR were significantly increased in Group 1 than Group 2 and Group 3, however, CLBR was similar between the three groups. The LBR were 46.6%, 40.5%, and 39.4% in Group 1, Group 2, and Group 3 respectively. The CPR were 53.0%, 47.0%, and 45.5%, respectively. The FR was highest in Group 1 (61.7%, P<0.05), but there was no uniform reverse trend with the AMH level. CLBR were 68.7%, 70.4%, and 71.3%, respectively. Although women in Group 1 were older (p < 0.05) and had higher body mass index (BMI) (p < 0.05), binomial logistic regression analysis used age, BMI, FSH, and AMH as independent variables indicated that only AMH was significantly associated with LBR and CPR. Nevertheless, binomial logistic regression analysis used age, BMI, FSH, AMH, and the number of retrieved oocytes as independent variables indicated that only the number of retrieved oocytes was significantly correlated with CLBR. After stratifying by age, the negative relationship between baseline AMH level and LBR and CPR remained only in the patients <30 years old.

CONCLUSIONS

Higher baseline AMH level in PCOS women resulted in lower LBR, CPR, and FR but did not influence CLBR.

Rescue In Vitro Maturation in Polycystic Ovarian Syndrome Patients Undergoing In Vitro Fertilization Treatment who Overrespond or Underrespond to Ovarian Stimulation: Is It A Viable Option? A Case Series Study

Background

This study intends to present the role of rescue in vitro maturation (IVM) in polycystic ovarian syn- drome (PCOS) patients undergoing in vitro fertilization (IVF) treatment who have inappropriate responses to ovarian stimulation.

Materials and Methods

This was a retrospective case series study of five PCOS patients undergoing IVF treatment considered for cycle cancellation due to increased risk of ovarian hyperstimulation syndrome (OHSS) as group A or poor response to ovarian stimulation as group B. Patients in group A had high oestradiol levels and recruitment of high numbers of small/intermediate sized follicles that did not meet the criteria for human chorionic gonadotropin (hCG) triggering. Patients in group B responded inadequately to hormonal stimulation despite high gonadotropin dosage. Treatment was changed to rescue IVM cycles after the patients provided consent.

Results

In group A, three IVF patients deemed to have high chances of developing OHSS as evidenced by high oestradiol levels were converted to IVM. A total of the 58/68 oocytes retrieved were mature or matured in vitro. There were 26 cleaving embryos obtained. Two patients had live births and one patient suffered a miscarriage. In group B, rescue IVM was implemented in two patients due to poor ovarian response (POR). A total of 22/26 oocytes retrieved were mature or matured in vitro. There were 13 cleaving embryos obtained. One patient had a live birth, whilst the other suffered a miscarriage.

Conclusion

Rescue IVM could be a viable option in PCOS patients undergoing IVF treatment who are unable to safely meet the criteria for hCG triggering due to overresponse to ovarian stimulation or ovarian resistance to high doses of stimulation. Conversion to IVM can still result in reasonable oocyte retrieval and lead to clinical pregnancy and live births without the risks of OHSS.

Lower antimüllerian hormone is associated with lower oocyte yield but not live-birth rate among women with obesity

BACKGROUND

Antimüllerian hormone is produced by small antral follicles and reflects ovarian reserve. Obesity is associated with lower serum antimüllerian hormone, but it is unclear whether lower levels of antimüllerian hormone in women with obesity reflect lower ovarian reserve.

OBJECTIVE

To determine whether lower antimüllerian hormone in women with obesity undergoing in vitro fertilization is associated with oocyte yield and live-birth rate.

MATERIALS AND METHODS

Retrospective cohort from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System database of 13,316 women with obesity and 16,579 women with normal body mass index undergoing their first autologous in vitro fertilization with fresh transfers between 2012 and 2014. Normal body mass index was defined as body mass index 18.5-24.9 kg/m², and obesity was defined as body mass index ≥30 kg/m². Subjects with obesity were stratified as those with class 1 obesity (body mass index, 30.0-34.9 kg/m²), class 2 obesity (body mass index, 35.0-39.9 kg/m²), and class 3 obesity (body mass index, ≥40 kg/m²) based on the World Health Organization body mass index guidelines. Antimüllerian hormone levels were stratified as normal (>1.1 ng/mL), low (0.16-1-1 ng/mL), and undetectable (≤0.16 ng/mL). Multivariable modeling was used to assess oocyte yield using linear regression with a logarithmic transformation and odds of live birth using logistic regression.

RESULTS

Women with obesity were older (36.0 ± 4.8 vs 35.5 ± 4.8, P < .001), had lower antimüllerian hormone (1.8 ± 2.0 ng/mL vs 2.1 ± 2.0 ng/mL, P < .001), and had fewer oocytes retrieved (11.9 ± 7.3 vs 12.8 ± 7.7, P < .001) than women with normal body mass index. Lower oocyte yield was observed among women with obesity and normal antimüllerian hormone levels compared to women with normal body mass index and normal antimüllerian hormone levels (13.6 ± 7.3 vs 15.8 ± 8.1, P < .001). No difference in oocyte yield was observed among women with obesity and low antimüllerian hormone levels (P = .58) and undetectabl antimüllerian hormone (P = .11) compared to women with normal BMI and similar antimüllerian hormone levels. Among women with a body mass index ≥30 kg/m², antimüllerian hormone levels were associated with the number of oocytes retrieved (β = 0.069; standard error, 0.005; P < .001) but not live-birth rate (odds ratio, 0.98; 95% confidence interval, 0.93-1.04, P = .57).

CONCLUSION

Lower antimüllerian hormone in infertile women with obesity appears to reflect lower ovarian reserve, as antimüllerian hormone is associated with lower oocyte yield. Despite lower oocyte yield, lower antimüllerian hormone was not associated with lower live-birth rate among women with obesity.

High serum Antimullerian hormone levels are associated with lower live birth rates in women with polycystic ovarian syndrome undergoing assisted reproductive technology

INTRODUCTION

Antimullerian hormone (AMH) strongly correlates with ovarian reserve and response to controlled ovarian stimulation. Emerging data suggests that serum AMH level may also predict ART outcomes. However, AMH is characteristically elevated in PCOS women and it is unknown whether it may predict live birth outcomes in this population.

METHODS

This was a retrospective cohort study of 184 PCOS women (Rotterdam criteria) who underwent their first fresh IVF/ICSI cycle. Women were divided into 3 groups according to the <25th (low), 25 to 75th (average), or > 75th (high) percentile of serum AMH concentration. Cycle stimulation parameters and reproductive outcomes were compared between groups.

RESULTS

Women in the low serum AMH group were older than those in the average or high AMH (p < 0.05), and required greater gonadotropin dose for stimulation compared to the high AMH group (p < 0.05). Women with high AMH had greater testosterone level compared to women in the low or average AMH groups. No differences were noted between groups in terms of maximal E2, oocytes retrieved and fertilization rate. However, low serum AMH women had significantly greater live birth rates (p < 0.05) and showed a trend towards greater clinical pregnancy rates compared to women in the average and high AMH groups (p = 0.09). The significant association of AMH with live birth rate remained after adjusting for age, BMI, day of transfer and number of embryos transferred.

CONCLUSIONS

In PCOS women, elevated AMH concentrations are associated with hyperandrogenism and lower live birth rates.

Cumulative live birth rates after IVF in patients with polycystic ovaries: phenotype matters

RESEARCH QUESTION

Do cumulative live birth rates (CLBR) vary among women with different polycystic ovary syndrome (PCOS) phenotypes who undergo IVF/intracytoplasmic sperm injection (ICSI) treatment?

DESIGN

In this retrospective cohort study, data from 567 patients undergoing an assisted reproductive technology (ART) cycle between January 2010 and December 2015 were collected. Demographical traits, cycle characteristics and clinical and laboratory data were analysed.

RESULTS

After conventional ovarian stimulation using a gonadotrophin-releasing hormone antagonist protocol, the median number of oocytes retrieved ranged between 11 and 13.5 and did not differ significantly among the studied groups. Live birth rate (LBR) after fresh embryo transfer and CLBR after transfer of all fresh and vitrified embryos were significantly lower in women with hyperandrogenic PCOS phenotypes A (LBR 16.7%, CLBR 25.8%) and C (LBR 18.5%, CLBR 27.8%) compared with women with normoandrogenic PCOS phenotype D (LBR 33.7%, CLBR 48%) (P-value for LBR 0.01 and 0.03, respectively; P-value for CLBR 0.002 and 0.01, respectively) and controls with a polycystic ovarian morphology (LBR 37.1%, CLBR 53.3%) (P-value for LBR 0.002 and 0.01, respectively; P-value for CLBR <0.001 and 0.001, respectively). Multivariate regression analysis indicated that after adjustment for relevant confounders, PCOS phenotype was an independent predictor for CLBR.

CONCLUSIONS

Hyperandrogenic PCOS phenotypes confer significantly lower CLBR compared with their normoandrogenic counterparts. These findings may imply the need for adapted counselling and tailored approaches when treating PCOS patients with hyperandrogenism who require ART.

The role of AMH in the pathophysiology of polycystic ovarian syndrome

Polycystic ovarian syndrome (PCOS) affects 5 - 10% of reproductive age women, but its pathogenesis is still poorly understood. The aim of this review is to collate evidence and summarize our current knowledge of the role of anti-Müllerian hormone (AMH) in PCOS pathogenesis. AMH is increased and correlated with the various reproductive and metabolic/endocrine alterations in PCOS. AMH plays an inhibitory role in follicular development and recruitment, contributing to follicular arrest. AMH inhibitory action on FSH-induced aromatase production likely contributes to hyperandrogenism in PCOS, which further enhances insulin resistance in these women. Elevated serum AMH concentrations are predictive of poor response to various treatments of PCOS including weight loss, ovulation induction and laparoscopic ovarian drilling, while improvement in various clinical parameters following treatment is associated with serum AMH decline, further supporting an important role for AMH in the pathophysiology of this syndrome. This review emphasizes the need for understanding the exact mechanism of action of AMH in the pathophysiology of PCOS. This may lead to the development of new treatment modalities targeting AMH to treat PCOS, as well as help clinicians in prognostication and better tailoring existing treatments for this disease.

Circulating anti-mullerian hormone as predictor of ovarian response to clomiphene citrate in women with polycystic ovary syndrome

BACKGROUND

To investigate the impact of high circulating AMH on the outcome of CC ovulation induction in women with PCOS.

METHODS

This prospective cohort observational study included 81 anovulatory women with PCOS who underwent 213 cycles of CC ovarian stimulation. Serum AMH concentrations were measured on cycle day 3 before the commencement of CC in the first cycle, which were compared between responders and CC-resistant anovulation (CRA). Logistic regression analysis was applied to study the value of serum AMH for the prediction of ovarian responsiveness to CC stimulation. The receiver-operating characteristic (ROC) curve was used to evaluate the prognostic value of circulating AMH.

MAIN OUTCOME MEASURES

Serum AMH levels.

RESULTS

Women who ovulated after CC therapy had a significantly lower AMH compared with the CRA (5.34 ± 1.97 vs.7.81 ± 3.49, P < 0.001). There was a significant gradient increase of serum AMH levels with the increasing dose of CC required to achieve ovulation (P < 0.05). In multivariate logistic regression analysis, AMH was an independent predictor of ovulation induction by CC in PCOS patients. ROC curve analysis showed AMH to be a useful predictor of ovulation induction by CC in PCOS patients, having 92 % specificity and 65 % sensitivity when the threshold AMH concentration was 7.77 ng/ml.

CONCLUSION

Serum AMH may be clinically useful to predict which PCOS women are more likely to respond to CC treatment and thus to direct the selection of protocols of ovulation induction.

The role of serum AMH and FF AMH in predicting pregnancy outcome in the fresh cycle of IVF/ICSI: a meta-analysis

PURPOSE

This meta-analysis tries to find and confirm the true prognostic value of serum AMH and the follicle fluid AMH (FF AMH) on the outcome of ART.

METHOD

We identified all studies published by March 2014 with data related to in vitro fertilization", "intracytoplasmic sperm injection", "assisted reproductive technology" and "antimullerian hormone" in Pubmed database. Studies were included if 2 × 2 tables for outcomes of pregnancy in IVF patients in relation to AMH could be constructed or studies which used T-tests to compare clinical indexes including AMH in pregnant and non-pregnant women. And all the patients were less than 46 years old.

RESULTS

A total of 26 studies could be used for this meta-analysis. Of these articles 22 studies could be constructed 2 × 2 tables, with 15 for predicting pregnancy and 7 for non-pregnancy. 11 studies used the analysis of T-test, with 7 articles were duplicated. And of the 11 articles, 8 were for the analysis of serum AMH in prediction of pregnancy, 3 were for FF AMH. Because of heterogeneity among studies, calculation of a summary point estimate for sensitivity and specificity was not possible. For the analysis of serum AMH on non-pregnancy, the heterogeneity was moderate (I-squared of 65.9%), the curves indicated positive find (the AUROC is 0.73, 95% CI is 0.69-0.77.). In the T-test group of serum AMH, the DOR for women with pregnancy outcome was 0.232 (95% confidence interval (CI): 0.034-0.43), with less heterogeneity (I-squared of 45.1%). Unfortunately, the predictive value of FF AMH on pregnancy is still unclear because of large heterogeneity (I-squared of 90.5%).

CONCLUSION

Serum AMH, as an independent parameter, can predict pregnancy outcome after assisted conception and the positive correlation with serum AMH and non-pregnancy should not be ignored either. The predictive value of FF AMH on pregnancy is still unclear.

Antimüllerian hormone as predictor of implantation and clinical pregnancy after assisted conception: a systematic review and meta-analysis

OBJECTIVE

To assess whether antimüllerian hormone (AMH) is a predictor of implantation and/or clinical pregnancy in women undergoing assisted reproductive technology.

DESIGN

Systematic review and meta-analysis.

SETTING

Not applicable.

PATIENT(S)

Women undergoing IVF/intracytoplasmic sperm injection in nondonor cycles.

INTERVENTION(S)

Measurement of serum AMH level.

MAIN OUTCOME MEASURE(S)

Diagnostic odds ratio (OR) and summary receiver operating characteristic curve (AUC) for AMH as a predictor of implantation and/or clinical pregnancy.

RESULT(S)

A total of 525 observational studies were identified, of which 19 were selected (comprising 5,373 women). Studies reporting clinical pregnancy rates in women with unspecified ovarian reserve (n = 11), diminished ovarian reserve (DOR) (n = 4), and polycystic ovary syndrome (n = 4) were included, together with studies reporting implantation rates (n = 4). The OR for AMH as a predictor of implantation in women with unspecified ovarian reserve (n = 1,591) was 1.83 (95% confidence interval [CI] 1.49-2.25), whereas the AUC was 0.591 (95% CI 0.563-0.618). The OR for AMH as a predictor of clinical pregnancy in these women (n = 4,324) was 2.10 (95% CI 1.82-2.41), whereas the AUC was 0.634 (95% CI 0.618-0.650). The predictive ability of AMH for pregnancy was greatest in women with DOR (n = 615), with OR and AUC of 3.96 (95% CI 2.57-6.10) and 0.696 (95% CI 0.641-0.751), respectively. In contrast, AMH had no significant predictive ability in women with PCOS (n = 414), with OR and AUC of 1.18 (95% CI 0.53-2.62) and 0.600 (95% CI 0.547-0.653), respectively.

CONCLUSION(S)

Antimüllerian hormone has weak association with implantation and clinical pregnancy rates in assisted reproductive technology but may still have some clinical utility in counseling women undergoing fertility treatment regarding pregnancy rates, particularly those with DOR.

Characterization of women with elevated antimüllerian hormone levels (AMH): correlation of AMH with polycystic ovarian syndrome phenotypes and assisted reproductive technology outcomes

OBJECTIVE

Serum Antimüllerian hormone (AMH) levels are elevated in polycystic ovarian syndrome and have been shown to be useful in its diagnosis. However, the clinical significance of extremely high AMH levels is understudied. We aimed to characterize a population of women with elevated AMH (>5 ng/mL).

STUDY DESIGN

This was a retrospective cohort study of 134 women presenting to our fertility clinic for infertility evaluation and treatment who were found to have random serum AMH over 5 ng/mL. Women were divided into 3 groups according to AMH: 5-10 ng/mL, >10-14 ng/mL, and >14 ng/mL. Endocrine characteristics, polycystic ovarian syndrome (PCOS) phenotypes, fertilization rate, implantation rate, clinical pregnancy, and multiple pregnancy rates were compared between groups.

RESULTS

AMH ranged between 5 to 48 ng/mL. Greater than 97% of women with ultrahigh AMH (>10 ng/mL) had PCOS. In addition, women with AMH >10 ng/mL had greater prevalence of polycystic ovarian morphology and oligoamenorrhea than women with AMH 5-10 ng/mL. Moreover, serum AMH correlated positively with luteinizing hormone, total testosterone, and dehydroepiandrosterone sulfate. Furthermore, AMH showed strong predictive ability for the presence of amenorrhea (area under the curve, 0.87; 95% confidence interval, 0.80-0.92; P < .0001). Despite similar age and mean number of transferred embryos, women with AMH >10 ng/mL showed higher rates of ovarian hyperstimulation syndrome and clinical pregnancy rates compared with women with AMH 5-10 ng/mL.

CONCLUSION

These data characterize a population of women with elevated AMH levels, demonstrating that the vast majority of women with AMH >10 ng/mL have PCOS. Increased AMH levels correlated with PCOS severity and are associated with greater ovarian stimulation and higher clinical pregnancy rates following assisted reproductive technology.

Relation of antimullerian hormone with the clinical signs of hyperandrogenism and polycystic ovary morphology

The relation of antimullerian hormone (AMH) levels with the clinical and biochemical markers of polycystic ovary syndrome (PCOS) could be different. A total of 463 PCOS patients were evaluated in this cross-sectional study. Groups were constructed according to polycystic ovarian morphology (PCOM) and menstrual cycle-length. The relation of serum AMH with androgenic hormones, menstrual cycle-length and clinical signs of PCOS were investigated. A powerful positive relation was found between the PCOM and AMH levels (odds ratio = 2.49). There was a negative correlation between age and AMH level (p < 0.001, r[correlation coefficent] = -0.155). Positive correlations were found between luteinizing hormone (LH) and AMH (p < 0.001, r = 0.25) and also between cycle length and AMH (p < 0.01, r = 0.27). We found a negative week correlation between AMH and follicle-stimulating hormone (FSH) (p = 0.01, r = -0.19). After controlling main androgenic hormones, AMH was found to be correlated with the Ferriman-Gallway score (p = 0.03, r = 0.18). There was a positive relationship between hirsutism and AMH (odds ratio = 1.43), but no correlation between AMH and other parameters of clinical hyperandrogenism like hair-loss, acne and seborrhea were identified. The strongest relation was presented between the AMH levels and PCOM. Also, cycle-length correlated well with the AMH levels. The relationship between hirsutism and AMH is found to be independent from androgenic hormones.

The influence of circulating anti-Müllerian hormone on ovarian responsiveness to ovulation induction with gonadotrophins in women with polycystic ovarian syndrome: a pilot study

BACKGROUND

Women with polycystic ovarian syndrome (PCOS) are known to have elevated circulating Anti-Müllerian hormone (AMH), which has been found to desensitize ovarian follicles to follicle stimulating hormone (FSH). The purpose of this study was to investigate the impact of high circulating AMH on ovarian responsiveness to ovulation induction with gonadotrophins in PCOS women.

METHODS

This prospective observational pilot study was conducted in two collaborating Fertility Centres in the UK and Egypt. The study included 20 consecutive anovulatory women with PCOS who underwent 34 cycles of human menopausal gonadotrophin (hMG) ovarian stimulation using chronic low-dose step up protocol. Blood samples were collected for the measurement of serum AMH concentrations in the early follicular (day 2-3) phase in all cycles of hMG treatment. The serum levels of AMH were compared between cycles with good vs. poor response. The good response rates and the total dose and duration of hMG treatment were compared between cycles with high vs. low serum AMH concentrations.

RESULTS

Cycles with poor response (no or delayed ovulation requiring >20 days of hMG treatment) had significantly (p = .007) higher median{range} serum AMH concentration (6.5{3.2-13.4}ng/ml) compared to that (4.0{2.2-10.2}ng/ml) of cycles with good response (ovulation within 20 days of hMG treatment). ROC curve showed AMH to be a useful predictor of poor response to hMG stimulation (AUC, 0.772; P = 0.007). Using a cut-off level of 4.7 ng/ml, AMH had a sensitivity of 100% and specificity of 58% in predicting poor response. The good response rate was significantly (p < .001) greater in cycles with lower AMH (<4.7 ng/ml) compared to that in those with AMH > = 4.7 ng/ml (100% vs. 35%, respectively). All cycles with markedly raised serum AMH levels (> 10.2 ng/ml) were associated with poor response. Cycles with high AMH (> = 4.7 ng/ml) required significantly (p < .001) greater amounts (median {range}, 1087{450-1650}IU) and longer duration (20 {12-30}days) of hMG stimulation than cycles with lower AMH (525 {225-900}IU and 8{6-14}days).

CONCLUSIONS

PCOS women with markedly raised circulating AMH seem to be resistant to hMG ovulation induction and may require a higher starting dose.

Anti-Müllerian hormone and polycystic ovary syndrome: assessment of the clinical pregnancy rates in in vitro fertilization patients

OBJECTIVE

The purpose of this study is to investigate the role of serum anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH) and antral follicle count (AFC) for the prediction of clinical pregnancy rates (CPR) in women with polycystic ovary syndrome (PCOS) undergoing IVF treatment.

DESIGN

Prospective cohort study.

SETTING

University hospital.

PATIENTS

One hundred and fifty consecutive women with PCOS.

INTERVENTIONS

All women underwent controlled ovarian stimulation with long agonist protocol followed by IVF procedure. Outcomes of pregnant and non-pregnant groups were compared.

MAIN OUTCOME MEASURE

CPR; AMH, FSH and AFC means and percentiles.

RESULTS

Fifty-one (34%) clinical pregnancies were observed in 150 women. Mean AMH was 6.7 ± 2.8 and 7.1 ± 4.3 ng/mL in pregnant and non-pregnant women, respectively (p = 0.594). The CPR were 27.8%, 35.0% and 37.8% in <25%, 25%-75% and >75% AMH percentiles, respectively (p = 0.656). There were also no significant difference in mean FSH and AFC between pregnant and non-pregnant women (p = 0.484 and p = 0.165, respectively).

CONCLUSION

AMH, FSH and AFC are not predictive for CPR in women with PCOS undergoing IVF treatment. Mean AMH values were not significantly different between pregnant and non-pregnant women. Although CRP increased in parallel with the raise in AMH percentiles, this remained insignificant.
