Brief summary

The primary purpose of this study is to assess that ganirelix is safe and well-tolerated in Chinese women and that a controlled ovarian stimulation (COS) protocol combining recombinant follicle stimulating hormone (recFSH) with ganirelix is efficient in Chinese women undergoing COS for in vitro fertilization (IVF) or intra cytoplasmatic sperm injection (ICSI).

Interventions

DRUGganirelix

On day 6 of recFSH treatment, Org 37462 treatment will start by daily SC administration (0.25 mg) up to and including the day of hCG administration.

DRUGtriptorelin

a daily dose of 0.05 mg SC is to be injected. Triptorelin treatment will start in the luteal phase at day 21-24 of the menstrual cycle. Treatment with recFSH will start 14 days later if treatment with triptorelin has resulted in downregulation, i.e. serum E2 \<= 50 pg/ml (\<= 200pmol/l). In case the hypogonadotropic state is not reached after 14 days of pretreatment, the dose of triptorelin will be increased to 0.1 mg. If downregulation is not reached within 28 days of pre-treatment with triptorelin, the subject will be discontinued from further hormonal treatment. The daily dose of triptorelin is sustained up to and including the day of hCG.

Outcome results

Primary

The Amount of International Units (IU) of Recombinant Follicle Stimulating Hormone (recFSH) Needed in a Controlled Ovarian Stimulation (COS) Cycle up to the First Day the Human Chorionic Gonadotropin (hCG) Criterion is Met.

The hCG criterion is met the first day that 3 follicles \>= 17 mm are observed.

Time frame: At completion of ovarian stimulation; maximally after 18 days of recFSH administration.

Population: The number of participants for this analysis included only those participants in the intent-to-treat (ITT) group who received hCG and for whom data was available.
