The patient was a 33-year old primary infertile woman due to male’s factors and underwent her second in vitro fertilization (IVF) cycle using GnRH agonist protocol, and no oocytes harvested on ovum picked-up (OPU) day. The start of gonadotropin usage was on day 8th of her period, and the P level increased rapidly and strangely high from day 8th after gonadotropin usage. The E2 level and follicles grew normally but finally no oocytes harvested. She was diagnosed as late ovarian hyper-stimulation syndrome (OHSS) 7 days after OPU. 20 days after OPU, no menstruation come and a positive urine test of hCG were reported. And the patient was diagnosed as EP by laparoscopy. In conclusion, rapidly increased P level, no oocyte retrieval and late onset of OHSS should be very important clues to diagnose this misdiagnosed EP.展开更多

Progestin-primed ovarian stimulation (PPOS) protocol, which used oral progestin to prevent premature luteinizing hormone (LH) surges in ovarian stimulation, has been proved to be effective and safe in patients with PCOS. The aim of the present study was to compare the efficacy of PPOS protocol with that of the traditional gonadotropin-releasing hormone (GnRH) antagonist protocol in patients with PCOS. A total of 157 patients undergoing in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) were recruited into this study. The patients were divided into two groups by the stimulation protocols: the GnRH antagonist protocol group and the PPOS protocol group. There was no significant difference in the clinical characteristics between the two groups. Dose and duration of gonadotropin were higher in the PPOS protocol group. Estradiol levels on the day of human chorionic gonadotropin (hCG) administration were significantly lower in the PPOS protocol group. Fertilization rates and the number of good quality embryos were similar between the two groups. Remarkably, we found 6 patients with moderate ovarian hyperstimulation syndrome (OHSS) in the GnRH antagonist protocol group but 0 in the PPOS protocol group. A total of 127 women completed their frozen embryo transfer (FET) cycles. There were no significant differences between the two groups in terms of clinical pregnancy rate per transfer, implantation rate, first-trimester miscarriage rate and on-going pregnancy rate per transfer. To conclude, PPOS protocol decreased the incidence of OHSS without adversely affecting clinical outcomes in patients with PCOS.展开更多
