Aims of the study: To evaluate the histological and histochemical changes induced by human chorionic gonadotropin (hCG) on the adult prostate and to correlate the changes with the levels of testosterone. Materials and Methods: eighty adult male albino rats were divided into 4 groups; 3 treated and 1 control. The treated groups were received 10, 50 or 100 IU/kg BW of hCG, while the controls received normal saline. The doses were given twice weekly for 3 months via subcutaneous injections. Subsequently, on day 1, 30, 60 and 90 post therapy, blood samples and the prostate glands were obtained for evaluation. Results: All the doses of hCG caused accumulation of secretory products within the prostate, which resulted in dilatation of the acinar lumens, reduction of the mucosal folds, and non dose dependent diminution in height of the lining epithelial cells. Moreover, foci of hyperplasic cells were observed in the prostate. The therapy increased the collagen fibers of the gland. The general distribution of the Periodic Acid-Sciff (PAS) +ve material was not altered. Most of these changes were reversible within 3 months. Conclusions: Treatment with hCG causes accumulation of secretory products within the prostate and in turn affects the structure of the prostate.

Aims of the study: To evaluate the histopathological changes induced by human chorionic gonadotropin (hCG) on the adult testis and to correlate the changes with the levels of testosterone, LH and FSH, as well as to assess their reversibility. Methods: 80 adult male albino rats were divided into 4 groups; 3 treated and 1 control. The treated groups were received 10, 50 or 100 IU/kg BW of hCG, while the controls received normal saline. The doses were given twice weekly for 3 months via S.C. injections. Subsequently, on day 1, 30, 60 and 90 post therapy, blood samples and the testes were obtained for evaluation. Results: Low dose of hCG caused increase in number of germ and Sertoli cells. Contrary, higher doses decreased their population, and resulted in exfoliation of the germ cells. Furthermore, reduction in the thickness of the tubular basement membrane, congestion of the inter-tubular blood vessels and interstitial bleeding were observed in the higher dose groups. All the doses caused interstitial oedema, hyperplasia and hypertrophy of Leydig cells, as well as diminution in the collagen fibers. All these changes were reversible within 3 months. Conclusions: Only the low doses of hCG stimulate the spermatogenesis, whereas higher doses suppress sperm production.
