Abstract
AIM
A prospective, non-comparative study was conducted to evaluate the efficacy and efficiency of a starting dose of 100 IU recombinant follicle stimulating hormone (rhFSH, Puregon) in women undergoing ovarian stimulation prior to in vitro fertilization (IVF).
METHODS
A total of 40 women were down-regulated with gonadotropin releasing hormone agonist (long protocol), then treated with a fixed dose of 100 IU rhFSH for the first 4 days, and the dose of gonadotropin administration was adjusted according to patient's response thereafter. A maximum number of 3 embryos were transferred in 32 patients.
RESULTS
Nine patients were treated with intracytoplasmic sperm injection, and 24 with conventional IVF. The duration of stimulation was 10.8 +/- 1.8 days, serum estradiol concentration on human chorionic gonadotropin day was 1693.0 +/- 1651.2 pg/mL, and 1480 +/- 450 IU rhFSH was used. A mean number of 8.4 +/- 5.7 oocytes were retrieved, 4.9 +/- 4.3 embryos obtained, 2.4 +/- 0.9 embryos transferred, and 3.5 +/- 3.2 embryos cryopreserved. The proportion of mature oocytes was 71.6%, and the fertilization rate was 86.4%. Clinical pregnancy was achieved in 8 patients (25.0%), and all of these pregnancies are ongoing or delivered. There were 3 cases of twin gestations (37.5%). The implantation rate was 13.1% (11/84). There was one case of moderate ovarian hyperstimulation syndrome, however, the patient recovered within 7 days without any complications.
CONCLUSION
The starting dose of 100 IU rhFSH has a good safety profile, and is adequate in controlled ovarian hyperstimulation for IVF with a small amount of gonadotropin administered.
