Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Total Number of Embryos on Day 3/Blastocysts on Day 5
Time Frame: Day 3 and Day 5
Age
Time Frame: Baseline
Duration of Infertility
Time Frame: Baseline
Number of Embryos/Blastocysts Transferred on Day 3 or Day 5
Time Frame: Day 3, Day 5

Time Frame: up to 5 months
Type of Infertility
Time Frame: Baseline
Clinical Pregnancy Rate
Time Frame: 5 months
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.
Live Birth Rate
Time Frame: 5 months
Number of live births expressed per 100 initiated cycles, aspiration cycles or embryo transfer cycles. When delivery rates are given, the denominator (initiated, aspirated, or embryo transfer cycles) will be specified
