The first phase of an assisted reproduction treatment consists of controlled ovarian stimulation with the aim of achieving an adequate number of follicles for in vitro fertilization.
There are different stimulation protocols depending on the drugs and the days of treatment. During a short cycle, the hormonal medication starts to be administered after menstruation.
Specifically, first the gonadotropins, which are involved in follicular growth, are started and then a GnRH antagonist such as Orgalutran is injected to prevent spontaneous ovulation. Finally, it will be necessary to inject an ovulation inducer to do the follicular puncture 36 hours later and obtain the mature eggs.
