Intervention: Collection of discarded blood samples and cumulus cells at the time of baseline infertility evaluation and transvaginal oocyte retrieval, respectively.

We investigated the effect of GnRH given after gonadotropin stimulation on follicle growth and oocyte quality in young calves in a transvaginal oocyte recovery program.

Methods: We studied 57 ASA I-II women patients undergoing elective termination of pregnancy and 55 control patients undergoing transvaginal oocyte puncture for in vitro fertilization.
