ObjectiveThis 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.MethodsThis 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.ResultsAMH 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).ConclusionAMH 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.
