Steroid treatment of male subfertility caused by antisperm antibodies.
47 subfertile men with significant titres of antisperm antibodies were treated with one of two steroid regimens. The results were assessed by changes in sperm-counts and in serum antibody titres and by subsequent pregnancies. 15 oligozoospermic men were treated with prednisone 5 mg three times a day for 3--12 months. Sperm-counts became normal in 10 men and 4 of their wives became pregnant. 14 men with normal sperm-counts received the same treatment: antibody titres fell slightly and 3 of their wives became pregnant. 18 other men with normal sperm-counts were given one or more courses of methylprednisolone 96 mg/day for 7 days. There was a more pronounced fall in antibody titres in these men, and 7 of their wives became pregnant. Testicular biopsies in 3 men with high titres of antibodies and very low sperm-counts which became normal with prednisone showed adequate spermatogenesis; however, focal round-cell infiltration of seminiferous tubules was observed in 1 case. It is suggested that a steroid-responsive immune orchitis can occur spontaneously in man, and may contribute to the infertility of men with antisperm antibodies.
