Brief Summary
Gonadotropin releasing hormone (GnRH) agonist is sufficient for triggering final oocyte maturation in GnRH antagonist protocol and can significantly reduce incidence of ovarian hyperstimulation syndrome (OHSS) in high-risk patients. However, lower oocyte yield was reported in patients with lower luteinizing hormone (LH) level post trigger with single injection of GnRH agonist, which might be related to the shorter duration and lower amount of LH induced by GnRH agonist. Our aim is to study repeated injection of GnRH agonist for preventing OHSS and maintaining clinical outcome in high risk patients who receive controlled ovarian stimulation in GnRH antagonist protocol.

Outcome Measures
Primary Outcomes (4)
clinical pregnancy rate per transfer cycle
1month post embryo transfer
numbers of patients having OHSS
2 weeks post trigger with repeated GnRHa
oocyte yield
Oocyte yield was defined as the ratio of the total number of collected oocytes to the number of follicles measuring ≥10 mm on the day of oocyte retrieval.
oocyte retrieval day (34 to 38 hours post the first trigger with GnRHa)
Oocyte maturity
Oocyte maturity was defined as the ratio of metaphase II (MII) oocytes to the number of collected oocytes in the patients undergoing with ICSI.
24 hours post oocyte retrieval day
Secondary Outcomes (4)
serum luteinizing hormone level 12 hours post first trigger
12 hours post trigger with the first injection of GnRHa
serum luteinizing hormone level 24 hours post first trigger
24 hours post the first injection of GnRHa
fertilization rate
48 hours post IVF/ICSI
implantation rate
1 month post embryo transfer
Study Arms (1)
Repeated GnRHa
EXPERIMENTALPatients were triggered with repeated GnRHa
Interventions
0.2 mg, ih, at night and 0.2 mg, ih, 12 hours later when at least one of the following criteria was reached: (i) serum E2 ≥3500 pg/ml, (ii) ≥18 follicles measuring ≥11 mm.
