Evaluation of semen and pituitary gonadotropin function in men with untreated Hodgkin's disease.

The reproductive capacities of 35 patients with Hodgkin's disease were assessed before treatment by semen evaluation and determination of basal hypothalamic-hypophyseal function and after stimulation with gonadotropin-releasing hormone (GnRH). Sixty-five percent of the patients had asthenozoospermia, 46% had teratozoospermia, and 28% had oligozoospermia. Normal semen was more frequently seen in asymptomatic patients (7 of 18) than in symptomatic patients (2 of 15). All the patients had normal basal follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels and significantly low testosterone (T) levels (P less than 0.01). The FSH response to 100 micrograms of GnRH was normal, but the LH responses were all significantly low, both as delta % (28.4% +/- 18.7% versus 52.4% +/- 25.3%, P less than 0.005) and as peak values (36.7 +/- 20.7 mIU/ml versus 59.4 +/- 26.4 mIU/ml, P less than 0.01). It is believed that abnormal semen is a specific symptom of Hodgkin's disease, secondary to functional insufficiency of the hypothalamic-hypophyseal axis, with a relative decrease in T production.
