Abstract
The authors treated 135 men who underwent varicocelectomy, but had sustained Leydig cell dysfunction disclosed by LHRH test with human chorionic gonadotropin (hCG). hCG was administered for 10 weeks: 50,000 units were given in 10 divided doses intramuscularly. Semen analysis and measurement of serum hormone level were obtained 8 weeks after the completion of treatment, and every 3 months after that. All patients were followed up for 2 years to confirm pregnancy. Fifty-five percent of patients achieved pregnancy and they showed significant increase in sperm density, percentage of sperm motility, normal form sperm, and serum testosterone level. It is recommended that hCG be administered to patients who undergo varicocelectomy but have persistent subtle Leydig cell dysftinction disclosed by LHRH test to stimulate the intratesticular testosterone production.
