OBJECTIVE: The aim of this pilot study was to determine whether the low anti-müllerian hormone (AMH) serum level, due to severe endometriosis, was associated with diminished oocyte yield, poor oocyte/embryo quality and reduced in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) clinical outcomes in young patients (<37 years old).
PATIENTS AND METHODS: A total of 50 IVF cycles of patients younger than 37 with severe endometriosis were retrospectively analyzed in a single center between November 2016 and July 2018. The clinical outcome was then compared to a control group of 84 patients with no story of endometriosis and normal AMH value. AMH value was evaluated within three months before the stimulation. In these two groups, number and maturation of retrieved oocytes, embryo quality, and pregnancy outcomes were evaluated and compared using Student's t-test and Fisher's test.
RESULTS: The number of oocytes retrieved per cycle and the percentage of mature oocytes (MII) were significantly lower (p < 0.001) in IVF patients with severe endometriosis and AMH value ≤ 1.1 ng/ml (Group A; 3.8±2.6 retrieved oocytes, 70% MII) compared to patients without endometriosis and AMH levels > 1.1 ng/ml (Group B; 6.9±4.6 retrieved oocytes, 83% MII). On the other hand, embryo morphology, implantation rate (31% vs. 33%; p = 0.833) and pregnancy rate (50% vs. 49%; p = 1) were comparable in the two groups.
CONCLUSIONS: This study shows that younger patients with an impairment of the ovarian reserve due to severe endometriosis, displayed a diminished oocyte yield but not a reduction in embryo quality and pregnancy outcomes. These results suggest that serum AMH levels should not be adopted as a criterion for discouraging these patients from undergoing IVF/ICSI treatments.
