Arms Assigned Interventions
Experimental: degarelix group
group of patients treated with long acting GnRH antagonist
Drug: degarelix (long acting GnRH antagonist)
20 mg of degarelix the first day of menstrual cycle before starting with gonadotrophins administration
Other Name: Firmagon
Active Comparator: Cetrorelix 0.25mg
patients treated with gonadotropin and Cetrorelix ina flexible GnRH antagonist protocol
Drug: cetrorelix 0.25mg
0.25mg of cetrorelix during treatment with gonadotrophins when estradiol levels were >300pg/ml
Other Name: cetrotide

Detailed Description:
Women with PCOS are at risk to develop OHSS when stimulated with gonadotrophins for IVF. For this reason in this study the degarelix was tested in order to minimize the risk of OHSS as well as to improve the pregnancy rate in these patients. The use of long acting GnRH antagonist promotes a deep suppression of LH and consequently the activity of theca cells, which secrete androgens (the precursors of estradiol), and consequently the levels of estradiol remains low. Comparing the long acting GnRH antagonist at the first day of cycle with a flexible GnRH antagonist protocol in a group of patients with PCOS will be useful in order to establish the best way to perform controlled hyperstimulation in IVF cycles and minimize the risk of OHSS.
