High anti-Müllerian hormone levels might not reflect the likelihood of clinical pregnancy rate in IVF/ICSI treatment.

OBJECTIVE: To investigate if high anti-Müllerian hormone (AMH) concentration is a useful tool to predict the outcome of assisted reproductive treatment. METHODS: Retrospective cohort study involving 520 patients who underwent IVF/ICSI procedures in a university hospital. We measured the serum AMH level on day 3 of the menstrual cycle. Based on AMH levels, we divided the patients into three groups as follows: low (<25th percentile) AMH group, average (25th to 75th percentile) AMH group and high (>75th percentile) AMH group. We recorded the fertilization rate (FR), the number of oocytes retrieved, the number of good quality embryos (GQEs) and the clinical pregnancy rate (CPR). RESULTS: There was no difference between the three AMH groups in terms of maternal age, body mass index (BMI), follicle-stimulating hormone (FSH), estradiol (E2), luteinizing hormone (LH) and testosterone (T) in the IVF/ICSI cycles. The women in the high serum AMH group had a higher number of retrieved oocytes than those in the low or average AMH groups (p < 0.01) in the IVF/ICSI cycles. Compared with the low or average AMH groups, the women with high AMH levels had a higher number of good quality embryos (GQEs) in the IVF/ICSI cycles (p < 0.01). However, high AMH women had no significantly higher clinical pregnancy rate (CPR) compared to the women in the low or average AMH groups. In addition, for the prediction of CPR, the AMH levels alone were not an independent predictor of CPR for IVF and ICSI cycles in the ROC curve analysis. CONCLUSIONS: High anti-Müllerian hormone levels are an independent predictor of the number of retrieved oocytes and good quality embryos (GQEs), but might not reflect the likelihood of higher clinical pregnancy rates (CPR) in IVF/ICSI treatment.

Prediction of metaphase II oocytes according to different serum Anti-Müllerian hormone (AMH) levels in antagonist ICSI cycles.

OBJECTIVE: This paper aims to assess a qualitative aspect of ovarian response in terms of metaphase II oocytes according to different serum Anti-Müllerian hormone levels in antagonist ICSI cycles. A prediction index might contribute to the individualization of care. METHODS: This observational study looked into 287 antagonist ICSI cycles carried out with patients treated in a single center between January of 2012 and January of 2016. Serum AMH and subgroup analyses were performed based on five AMH ranges (≤ 0.3 ng/mL;> 0.3 and ≤ 0.7 ng/mL; > 0.7 and ≤ 1.0 ng/mL; > 1.0 and < 3.0 ng/mL; ≥ 3.0 ng/mL). The variables analyzed included patient age; serum FSH and antral follicle count at the start of the cycle; number of stimulation days and number follicles ≥ 15 mm on hCG day; number of oocytes retrieved and number of metaphase II oocytes. RESULTS: AMH is a better predictor of ovarian response to controlled ovarian stimulation than AFC or serum FSH, while age is an independent marker. AMH levels ≤0.70 (patients with poor prognosis) were observed in 140 patients (48.7%). Patients within this AMH level range accounted for 92% of the 24 failed cycles (cancelled cycles, no oocytes or immature oocytes retrieved). CONCLUSION: AMH predicts the quality of ovarian response to stimulation, regardless of patient age. Women with AMH levels ≥1.0 and ≤3.0 ng/mL are probably normal responders with good prognosis. Clinical application relies on the examination of the data from each individual center and on the establishment of correlations between AMH levels and ovarian response in the form of metaphase II oocytes.
