This is a multicenter retrospective study in good prognosis Chinese patients. Data will be collected from infertile women who underwent first in vitro fertilization (IVF)/intra cytoplasmic sperm injection (ICSI) using a Gonadotropin releasing hormone (GnRH) antagonist (Cetrotide) protocol at about 4 IVF centers to investigate the factors associated with clinical pregnancy rate. The definition of the good prognosis subjects is, age not more than 35 years old, Baseline serum Follicle-stimulating hormone (FSH) level no more than 10 milliinternational units (mIU)/milliliter (ml), Body mass index (BMI) not more than 30 kilogram per meter square (kg/m^2), previously underwent no more than 3 IVF/ICSI cycles, and the total dose of Gonadotropin used no more than 2500 IU in current cycle. No intervention(s) will be administered on the subjects. Data required to investigate the factors associated with the pregnancy outcome of GnRH antagonist IVF cycle will be collected from the subjects' medical records into database through electronic data capture system and analyzed.

| Measure | Description | Time Frame |
|---|---|---|
| Clinical Pregnancy Rate | Number of clinical pregnancies expressed per 100 initiated cycles, aspiration cycles, and embryo transfer cycles. Initiated cycle: an assisted reproductive technology (ART) cycle in which the woman receives specific medication for ovarian stimulation, or monitoring in the case of natural cycles, with the intention to treat, irrespective of whether or not follicular aspiration is attempted. Aspiration cycle Initiated ART cycle in which one or more follicles are punctured and aspirated irrespective of whether or not oocytes are retrieved. Embryo transfer cycle: an ART cycle in which one or more embryos are transferred into the uterus or fallopian tube. | 5 months |
| Implantation Rate | Implantation rate = (The number of gestational sacs observed divided by the number of embryos transferred)*100 | 5 months |
| Ongoing Pregnancy Rate | Ongoing pregnancy rate per embryo transfer cycles = (Number of Ongoing pregnancy/Number of embryo transfer cycles)*100 and ongoing pregnancy rate per initiated cycles = (Number of Ongoing pregnancy/Number of initiated cycles) *100 | 5 months |
| Incidence and Severity of Ovarian Hyperstimulation Syndrome (OHSS) | 5 months | |
| Cycle Cancelled Rate | Cycle cancelled rate = (Number of subjects with terminated in vitro fertilization (IVF) or intra cytoplasmic sperm injection (ICSI) treatment/Number of initiated cycles)*100 | 5 months |
| Early Miscarriage Rate | (Number of Early miscarriages/Number of clinical pregnancies)*100 |
