Assessment

Primary outcomes

To establish a new controlled ovarian stimulation (COS) protocol for polycystic ovary syndrome (PCOS) that does not cause ovarian hyper stimulation syndrome (OHSS) while maintaining egg quality.

Interventions/Control_1

From the third (or fifth) day of the period, 5mg (or 2.5mg) of Letrozole and 150iu of HMG were administered every day until the day of trigger administration. When the leading follicle reached 18mm in diameter, the injection of 0.25mg of GnRH antagonist started and continued until the day of the trigger shot. After confirmation that the largest follicle was 22-24 mm in diameter and E2 level was about 500-700pg/ml, 5000iu of HCG was administered as trigger and oocyte collection was performed 37 hours later under general anesthesia with Propofol. All embryos were cryopreserved after IVF or ICSI. 2.5mg of Letrozole, 0.5mg of Cabergoline and 0.25mg of GnRH antagonist were administered just after the oocyte retrieval for five days consecutively.
