Response to luteinizing releasing hormone, thyrotrophic releasing hormone, and human chorionic gonadotropin administration in healthy men at different risks for prostatic cancer and in prostatic cancer patients.

A comparative study of the pituitary and testicular response to luteinizing releasing hormone (LHRH), thyrotrophic releasing hormone (TRH), and human chorionic gonadotrophin ( HCG) administration was carried out in (a) low-risk young South African black men and high-risk North American black men for prostatic cancer and (b) healthy elderly South African men and South African black men with prostatic cancer. A comparable HCG response occurred in young South African and North American black men, while a greater release of prolactin, but a lesser release of luteinizing hormone in response to LHRH:TRH occurred in South African black men. The response to HCG was comparable in elderly and young South African black men, although the prolactin release in response to TRH was greater in elderly men. A more prolonged release of luteinizing hormone was evident in men with prostatic cancer. Higher estradiol and estrone but lower androstenedione levels occurred in men with prostatic cancer. Data suggest that, in the elderly South African black men with prostatic cancer, estrogen metabolism is modified and that either the estrogen level or the higher estrogen:androgen levels modify the pituitary response to LHRH:TRH. A Western diet enhanced the changes in hormone profiles evident in black South African men with prostatic cancer.[1]
