Abstract

OBJECTIVES: To determine pregnancy and livebirth rates for women age 40 and older undergoing ovulation induction and to assess the impact of basal follicle-stimulating hormone (FSH) on outcome in these patients. DESIGN: Prospective, observational. SETTING: Fertility service of university medical center. PATIENTS: Infertile couples in whom the female partner was age 40 or older referred for ovulation induction therapy. INTERVENTION: Assessment of basal hormonal status; ovulation induction. MAIN OUTCOME MEASURES: Clinical pregnancy rate (PR), livebirth rate. RESULTS: Analysis of 402 cycles in 85 women age 40 and older demonstrated a clinical PR of 3.5% per cycle (95% confidence interval [CI] 1.7% to 5.3%). The livebirth rate was 1.2% per cycle (95% CI 0.1% to 2.3%). Women with a basal FSH < 25 IU/L and age or = 25 IU/L or age was > or = 44 (P < 0.005). The prognostic importance of basal FSH and chronological age was confirmed by multivariate logistic regression analysis. The predictive value of the resulting regression equation was high (R2 = 0.94; P < 0.01). CONCLUSIONS: Pregnancy and livebirth rates are generally low during ovulation induction in women age 40 and older. In combination, basal FSH and chronological age are accurate predictors of PR, in these couples and can define a subset of patients with a more favorable prognosis. The spontaneous abortion rate in women who do conceive is high, substantially lowering the livebirth rate.
