Abstract Background The concept of using a gonadotropin-releasing hormone agonist (GnRH-a) instead of human chorionic gonadotropin for triggering ovulation in patients treated with an antagonist protocol for in vitro fertilization (IVF) has become a routine clinical practice. It may promote oocyte nuclear maturation, resumption of meiosis and cumulus expansion. It seems that this attempt could be beneficial in an in vitro maturation (IVM) oocyte cycle performed for polycystic ovarian syndrome as well as for other indications such as urgent fertility preservation in patients with malignancies or unusual indications. Case presentation We present the case of a Caucasian patient who needed fertility preservation when routine natural IVF treatment did not yield oocyte retrieval, followed by three IVM cycles, priming ovulation with a GnRH-a. In total, 12 oocytes were obtained, all matured 4.5 hours after incubation in maturation media. The fertilization rate after intracytoplasmic sperm injection was 83%. Six good-quality embryos were vitrified. Conclusions It seems that triggering with a GnRH-a in selected cases may replace human chorionic gonadotropin in IVM of oocytes and could be highly beneficial in terms of obtaining high-grade embryos and possible pregnancy.
