ABSTRACT
In an attempt to induce or to augment pubertal development and to achieve spermatogenesis, 10 gonadotropin-deficient thalassemic patients 15 to 23 years of age (mean 18.9 years) were treated with exogenous gonadotropins for 1 to 4 years (mean 2.1 years). Seven patients produced sperm during human chorionic gonadotropin (hCG) treatment given for 6 to 14 months. However, full spermatogenesis was achieved only when human menopausal gonadotropin was added to hCG regimen. In one patient, despite cessation of gonadotropin treatment, sexual potency, libido, and spermatogenetic capacity were maintained during the past 2 1/2 years. Our study indicates that it is possible to induce or to restore spermatogenesis in the majority of thalassemic patients and that gonadotrope cells may not be irreversibly damaged by iron deposition.
