OBJECTIVE: To provide evidence of efficacy and safety for use of lutropin alfa in inducing follicular development and pregnancy in hypogonadotrophic hypogonadal women with profound gonadotrophin deficiency. DESIGN: An open-label, noncomparative extension of a randomized, double-blind, placebo-controlled study PATIENTS: A total of 31 hypogonadotrophic hypogonadal women with profound gonadotrophin deficiency in 23 medical centres in four countries were studied. INTERVENTIONS:Lutropin alfa 75 IU and follitropin alfa (75-225 IU), individually based on each patient's response as is consistent with usual medical practice. MEASUREMENTS: Follicular development as defined by (i) at least one follicle >or= 17 mm; (ii) preovulatory serum oestradiol level >or= 109 pg/ml on the day of hCG administration; and (iii) midluteal phase P(4) level >or= 7.9 ng/ml. Pregnancy and over-response leading to cycle cancellation were considered treatment successes. Pregnancy rates were assessed. RESULTS: In a total of 54 cycles, 27 of 31 (87.1%) profoundly gonadotrophin-deficient patients achieved follicular development within three cycles. Twenty of 27 patients (74.1%) who achieved follicular development and received hCG became pregnant; 16 (59.3%) continued to clinical pregnancy. One patient was hospitalized for severe ovarian hyperstimulation syndrome. Lutropin alfa was well tolerated. CONCLUSIONS: Coadministration of lutropin alfa 75 IU and follitropin alfa is safe and effective in inducing follicular development and pregnancy in hypogonadotrophic hypogonadal women with profound gonadotrophin deficiency in a setting consistent with established medical practice.
