The influence of ovarian hyperstimulation drugs on morphometry and morphology of human oocytes in ICSI program.

Objective: To compare the influences of controlled ovarian hyperstimulation (COH) drugs using recombinant follicular stimulating hormone (rFSH) versus human menopausal gonadotropins (hMG) on morphometry and morphology of MII oocytes in ICSI cycles.

Materials And Methods: In this prospective study, 363 MII oocytes from 50 ICSI cycles with male factor infertility were evaluated. The patients were divided into two groups according to the protocols of COH: I- rFSH and II- hMG.
