Registration Number

Lead Sponsor
Merck KGaA, Darmstadt, Germany
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.

Primary Outcome Measures

Total Number of Embryos on Day 3/Blastocysts on Day 5Day 3 and Day 5
AgeBaseline
Duration of InfertilityBaseline
Type of InfertilityBaseline
Number of Embryos/Blastocysts Transferred on Day 3 or Day 5Day 3, Day 5
Number of Good Quality Embryos/Blastocysts Transferredup to 5 months
Clinical Pregnancy Rate5 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 Rate5 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
