All cycles of IVF with pituitary down-regulation (n = 57) done at the Damansara Fertility Centre in the year 2000 were studied. All the 57 patients had controlled ovarian hyperstimulation, either using Metrodin HP (n = 27) or Gonal-F (n = 30). Of these, 53 patients reached oocyte pick-up, 26 patients in Metrodin HP group and 27 patients in Gonal-F group. Gonal-F resulted in a higher clinical pregnancy rate of 66.6% compared to Metrodin HP 38.5% (p < 0.05). The live birth rate tends to be higher in Gonal-F group (40.7%) compared to Metrodin HP (30.8%), (p > 0.05).
