Inhibitors for Ovulation Induction This year's meeting also included studies on the use of aromatase inhibitors for ovulation induction Mood swings are common but seldom severe; but if so please talk to us Some prefer to use it as a second line agent in women who fail to respond to clomifene citrate Apart from letrozole or CC, options for ovulation induction in polycystic ovarian syndrome (PCOS) patients are limited and thus leaving the use of gonadotropin injections as the only option of ovulation induction in these patients Ovulation induction medications can lead to multiple follicles developing and maturing in one menstrual cycle - meaning more than one egg may be released when you ovulate METHODS: This intervention is a clinical trial study carried out on 100 infertile women with
