Severe endometriosis: low value of AMH did not affect oocyte quality and pregnancy outcome in IVF patients.

OBJECTIVE The aim of this pilot study was to determine whether the low anti-mullerian 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 ( 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.
