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 dual trigger with GnRH agonist and human chorionic gonadotropin (hCG) for preventing OHSS and maintaining clinical outcome in high risk patients who receive controlled ovarian stimulation in GnRH antagonist protocol.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Oocyte maturity | 24 hours post oocyte retrieval day | Oocyte maturity was defined as the ratio of metaphase II (MII) oocytes to the number of collected oocytes in the patients undergoing with intracytoplasmic sperm injection (ICSI). |
| clinical pregnancy rate per transfer cycle | 1month post embryo transfer | — |
| numbers of patients having OHSS | 2 weeks post trigger with dual GnRHa | — |
| oocyte yield | oocyte retrieval day (34 to 38 hours post trigger with GnRHa and hCG) | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| serum luteinizing hormone level 12 hours post trigger | 12 hours post trigger | — |
| serum hCG level 12 hours post trigger | 12 hours post trigger | — |
| fertilization rate | 48 hours post IVF/ICSI | Fertilization rate was defined as the ratio of normal fertilized oocytes (2PNs) to the number of oocytes used for fertilization (i.e. the denominator in IVF in calculating fertilization rate is all oocytes recovered, but in ICSI it is calculated using only the number of MII oocytes). |
| implantation rate | 1 month post embryo transfer | — |
