1ST ESTABLISHED PREGNANCY AND BIRTH AFTER OVARIAN STIMULATION WITH RECOMBINANT HUMAN FOLLICLE-STIMULATING-HORMONE (ORG-32489)

This case report describes the first established pregnancy and birth a fter ovarian stimulation with Org 32489, pure recombinant human follic le stimulating hormone (recFSH, Organon International). A patient with tubal infertility participated in an open efficacy study of recFSH ev aluating the efficacy of combined gonadotrophin-releasing hormone (GnR H)-agonist/recFSH treatment in women undergoing in-vitro fertilization (IVF) and embryo transfer. Ovarian stimulation was induced by recFSH in association with buserelin (Suprecur(R), 4 x 150 mug/day) using a s hort protocol. After 9 days of recFSH treatment (75 IU/day), six pre-o vulatory follicles ( greater-than-or-equal-to 15 mm) were observed and 10 000 IU human chorionic gonadotrophin were administered. Nine matur e oocytes were retrieved by oocyte puncture and after IVF, three embry os were replaced in the uterus. A viable singleton intra-uterine pregn ancy was revealed at a gestational age of 7 weeks. The pregnancy progr essed normally and ended with a vaginal delivery at a gestational age of 39.5 weeks. A healthy girl was born and paediatric examination did not demonstrate any abnormality.
