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

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.

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.

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.

Predicting the outcome of different protocols of in vitro fertilization with anti-Muüllerian hormone levels in patients with polycystic ovary syndrome

Objective

This study evaluated associations of basal serum and follicular fluid (FF) anti-Muüllerian hormone (AMH) levels with in vitro fertilization (IVF) outcomes in polycystic ovary syndrome (PCOS) patients.

Methods

This prospective study included 179 consecutive women undergoing IVF, including 59 with PCOS and non-PCOS controls. Thirty PCOS cases had long gona-dotrophin-releasing hormone agonist (GnRH-a) and 29 had antagonist (GnRH-ant) protocols. Controls underwent conventional GnRH-a. Associations of basal serum and FF AMH levels with IVF outcomes were assessed.

Results

Median serum and FF AMH levels, antral follicle count (AFC), oestradiol human chorionic gonadotropin injection day (peak E2), and retrieved oocyte numbers were higher in PCOS patients than in controls (all P < 0.01). Oocyte maturation and high-quality embryo rates were lower in PCOS patients than in controls (P < 0.01), but both groups had similar fertilization, implantation, clinical pregnancy, and newborn rates. Peak E2 was higher in GnRH-ant than in GnRH-a protocols (16.5 nmol/L vs. 12.1 nmol/L, P < 0.05). AMH levels were correlated with AFC in PCOS patients (P < 0.01). Peak E2 and FF AMH levels were independent predictors of oocyte number. Peak E2 predicted the fertilization rate.

Conclusion

Serum basal AMH levels are predictive of oocyte quantity, but not oocyte quality or IVF outcomes. Serum AMH, FF AMH, and outcomes are similar among protocols.

The role of ovarian reserve markers in prediction of clinical pregnancy

To evaluate the role of ovarian reserve markers in the prediction of clinical pregnancy and embryo transfer accomplishment among poor responder IVF applicants. 304 female poor responder IVF applicants were included in this prospective cohort study conducted at the IVF-unit. Antral follicle count, FSH, LH, E2, AMH and IVF outcomes were compared in pregnant and non-pregnant groups as well as in ET vs. non-ET groups. The number of retrieved oocytes was significantly correlated positively with AMH and AFC, and negatively with FSH and age. Quartiles of FSH and AFC were similar to the rate of pregnancy. Quartiles of AMH (<25%/25-75% and <25%/>75%) were statistically significant. Mean serum levels for AMH were significantly lower in the non-ET group. Our findings seem to indicate that day 3 AMH values can predict ET accomplishment with a sensitivity of 96% and a specificity of 35%. Quartiles of AMH <25% (< 0.21 ng/mL) can predict the IVF results among poor responder IVF applicants. Impact statement Various cut-off values have been determined for day 3 serum AMH values. These values help to determine the groups that are expected to give normal, high or low response to stimulation and decide the treatment options. In contrast to other groups of patients, poor responders cannot reach the embryo transfer stage for several reasons. These are; absence of a mature oocyte after oocyte pick-up, fertilisation failure without male factor or poor embryo quality. In the present study; a cut-off value of 0.33 ng/mL for the prediction of ET accomplishment in poor responder patients was determined with a sensitivity of 96%. Additionally, clinical pregnancy could not be achieved under the value of 0.21 ng/mL day 3 AMH values. It is important to clarify the embryo transfer success of poor responder patients prior to expected treatment success. Pre-treatment counselling for these patients would lessen the disappointment that may develop after treatment. The cost-effectiveness of treatments below these AMH values can be determined by further studies.

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.

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.

Anti-müllerian hormone levels as a predictor of the pregnancy rate in women of advanced reproductive age

PURPOSE

To investigate whether serum anti-müllerian hormone (AMH), follicle stimulating hormone (FSH), or antral follicle count (AFC) are predictive for clinical pregnancy in women who underwent IVF cycles at the age of 35 and older

METHODS

A total of 240 consecutive women who underwent IVF cycles at the age of 35 and older were enrolled in this crsoss- sectional study. Pregnant and nonpregnant women were compared.

RESULTS

The median AMH level of pregnant women was higher than non-pregnant women [3.20 (0.63-9.60) vs 1.15 (0.01-14.90) ng/ml, p < 0.001]. On logistic regression analysis, AMH was an independent predictor of clinical pregnancy rate (CPR) (OR 1.353; 95 % CI 1.141-1.605; P < 0.001). After controlling for the other independent variables (the number of retrieved oocytes, AFC and age), the significant association between AMH and clinical pregnancy rate remained strong (OR 1.677; 95 % CI 1.216-2.311; p = 0.002) on multivariate logistic regression analysis.

CONCLUSIONS

AMH is an effective measure of quantitative ovarian reserve and it can predict ovarian response to controlled stimulation for advanced age women. The CPR tends to increase as AMH increases.

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.

Diagnosis of Polycystic Ovary Syndrome: AMH in combination with clinical symptoms

PURPOSE

We assessed the utility of using anti-Müllerian hormone (AMH) and clinical features of polycystic ovary syndrome (PCOS), polycystic ovarian morphology (PCOM), oligo/amenorrhea (OA), and hyperandrogenism (HA) for diagnosing PCOS, and compared their diagnostic accuracy with those of classical diagnostic systems.

METHODS

A total of 606 females were admitted to a university hospital with menstrual irregularities or symptoms of hyperandrogenism were enrolled in this cross-sectional study. Fasting blood samples were collected. Pelvic and/or abdominal ultrasonography and clinical examination were performed. Patients were evaluated for the presence of PCOS according to conventional diagnostic criteria. The diagnostic performance of using serum AMH levels alone and in various combinations with the clinical features of PCOM, OA, and HA were investigated.

RESULTS

For the diagnosis of PCOS, the combination of OA and/or HA with AMH showed 83% sensitivity and 100% specificity according to the Rotterdam criteria; 83% sensitivity and 89% specificity according to the National Institutes of Health (NIH) criteria; and 82% sensitivity and 93.5% specificity according to the Androgen Excess Society (AES) criteria.

CONCLUSIONS

The serum AMH level is a useful diagnostic marker for PCOS and is correlated with conventional diagnostic criteria. The combination of AMH level with OA and/or HA markedly increased the clinical scope for PCOS diagnosis and can be introduced as a possible objective criterion for the diagnosis of this disease.
