GNRH1 and ovarian hyperstimulation syndrome: Given the physiologic plausibility of the dual trigger (GnRH agonist + 1000 IU hCG) rescuing a small number of corpora lutea, we hypothesize that it would improve pregnancy rates, while decreasing the risk of OHSS, compared to administration of adjuvant low dose hCG of 1500 IU at the time of oocyte retrieval.
