| Measure | Time frame |
|---|---|
| Main Objective: To investigate whether ovarian hyperstimulation syndrome (OHSS) can be avoided with the delayed start of r-hFSH in ovarian stimulation for IVF treatment in subjects at increased risk of OHSS.;Secondary Objective: To study the ability to achieve a reasonable number of ongoing pregnancies with the planned study medication in this trial. ;Primary end point(s): The proportion of subjects without moderate or severe OHSS (defined by classification adapted from RCOG Green-Top Guideline no 5, 2006) (1). - Clinical pregnancy rate - Defined by positive pregnancy test (human chorionic gonadotropin (hCG), determined from urinary or serum sample) 14 days after embryo transfer and by presence of a gestational sac assessed by transvaginal ultrasound examination 5 weeks (± 1 week) after embryo transfer. - Number of cycle cancellations (defined as withholding of hCG injection) - Number of subjects with transferable embryos. - Number of subjects having frozen embryos - Severity of OHSS (none, mild, moderate, severe) - Adverse events - Pregnancy outcome up to 12 pregnancy weeks (Oocyte retrieval day = end of the second pregnancy week) | — |
