Effects of different methods of ovarian stimulation in adult rats

Abstract

The in vitro fecundation programs normally use different ovarian stimulation agents.The purpose of the present study was to compare the effects of some of these agents on indices of ovulation and serum levels of estradiol, progesterone, and FSH.Treatments studied consisted of clomiphene citrate, PMSG alone and in combination with clomiphene citrate, pure human FSH and epimestrol.The data obtained show PMSG alone and PMSG plus clomiphene citrate to be the most effective treatments, in terms of number of oocytes harvested.No differences were noted between serum levels of oestradiol, progesterone and FSH.
