In this retrospective study, a total of 122 infertile women were divided into two groups: group A, <35 years (n=71); group B, ≥35 years (n=51). AMH and FSH were determined on 2-5 d of the early menstrual cycle. AFC was tested on the second day of the menstrual cycle before the start of stimulation.
Group B had higher FSH levels compared with group A (8.2±3.5 IU/L vs 6.8±2.4 IU/L, P<0.05). However, levels of AMH and AFC in group B were lower than those of group A (AMH: 4.2±3.5 μg/L vs 2.7±2.7 μg/L; AFC: 9.0±3.9 vs 5.4±3.3, P<0.05). The number of oocyte retrieved in the two groups was not significantly different (11.5±6.8 vs 9.6±6.9, P>0.05). The level of AMH was more strongly correlated with the number of oocytes retrieved than that of AFC or FSH level. The strengths of the correlation degrees were AMH level, AFC, and FSH level in turn (r=0.600, 0.511, −0.369).
AMH would be a useful predictor for ovarian response.
