title: Follicle-stimulating hormone as a prognostic indicator in clomiphene citrate/human menopausal gonadotrophin-stimulated cycles for in-vitro fertilization.
abstract: Follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestradiol and prolactin levels were studied in a sequential clomiphene citrate/human menopausal gonadotrophin (CC/HMG) regimen for in-vitro fertilization. At completion of CC administration, the median FSH level in 44 cancelled cycles was elevated compared to a control group of 65 completed cycles, 29 IU/l versus 15 IU/l, P less than 0.01. Also the median FSH/LH ratio was higher in the cancelled cycles than in the control group, 1.08 versus 0.71, P less than 0.05. Conversely, the median oestradiol level was lower in the cancelled cycles than in the completed cycles, 0.27 nmol/l versus 0.59 nmol/l, P less than 0.01. No difference was seen in the median LH and prolactin levels. An FSH value above the 95% confidence limit was found in 24 of the cancelled cycles, but in only two of the completed cycles. Based on this study, an elevated FSH value following CC administration predicts a poor response to further stimulation with an accuracy of 92.3% and should result in cancellation of the cycle.
