High-dose follicle-stimulating hormone stimulation at the onset of the menstrual cycle does not improve the in vitro fertilization outcome in low-responder patients.
In an attempt to improve their outcome with in vitro fertilization (IVF), 34 low-responder patients were stimulated with six ampules of follicle-stimulating hormone (FSH) daily starting on day 1 (n = 17) or day 2 (n = 17) of their menstrual cycles. The stimulated cycles showed a mean peak estradiol of 443 +/- 173 pg/mL, mean days of human chorionic gonadotropin of 7.6 +/- 1.4, 2.67 +/- 1.5 preovulatory oocytes per retrieval, and 2.56 +/- 1.3 oocytes per transfer. Three clinical pregnancies resulted after 25 embryo transfer cycles (12%). With paired analysis, we compared 8 patient cycles with prior six ampules of FSH stimulation starting on day 3; all parameters examined showed no significant differences. In a comparison of 22 patient cycles with prior 4 ampules of FSH stimulation on cycle day 3, no significant differences in any parameters were observed except in the higher number of ampules used in the present study. We conclude that high-dose FSH stimulation at the onset of the menstrual cycle does not improve the IVF outcome in low-responder patients.
