The effort to minimize risks of ovulation induction with gonadotropins The aim of this study was to evaluate three different starting doses of follitropin beta based on patients' response to clomiphene citrate treatment to assess the lowest effective dose for follicular development. In fact the determination of the appropriate gonadotropins' starting dose to achieve only mono-follicular development is the most important issue in ovulation induction. This is the main goal to minimize cycle's cancellation due to low or high ovarian response and to prevent multiple pregnancies or ovarian hyperstimulation syndrome. The objective of the trial was to determine the effect of different follitropin beta dose (50, 75 and 100 IU daily) on follicular development, thickness of the endometrium, total consumption of gonadotropins per cycle etc. We evaluated 90 cycles with ovarian stimulation for 90 patients with unexplained infertility, mild male factor or anovulatory disorder. We prospectively divided patients into 50, 75 and 100 IU groups based on patients' response to clomiphene citrate treatment. We performed 85 intrauterine inseminations. We cancelled 5 cycles (1 cycle due to high ovarian response (1.1 %), 3 cycles due to low ovarian response, 1 cycle the other reason). We achieved 15 clinical pregnancies,...
