Summary. The present study was designed to determine the response of human epididymis, seminal vesicles and prostate function after a 5‐day course of clomiphene citrate in men attending an infertility service. In 45 men, the secretions of the epididymis, seminal vesicles and prostate were assessed by measurements of seminal α‐glucosidase, fructose and acid phosphatase, respectively. Subjects were classified as normal or abnormal: abnormal men were defined as those who either had history of a sexually transmitted disease (STD), leukocytosper‐mia, hypoandrogenism, or a low response of Leydig cells to clomiphene stimulation; and normal subjects were those who did not have these conditions. Mean serum testosterone luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels were significantly increased after the short course with clomiphene citrate. After clomiphene citrate stimulation, the men in the normal group showed significantly increased marker levels of the seminal vesicles ( P <0.02) and prostate ( P <0.05), but not of the epididymis ( P : NS). Men classified as abnormal showed no response according to the markers of the seminal vesicles and epididymis. Men with history of STD and abnormal basal values of acid phosphatase did not respond to the treatment. Men with history of STD but normal basal values of seminal acid phosphatase increased significantly in their levels of seminal acid phosphatase after clomiphene stimulation ( P <0.02). Multivariate analysis showed that the basal serum testosterone level was the only variable in predicting the probability of response to the clomiphene in terms of true‐corrected seminal fructose, seminal acid phosphatase and seminal α‐glucosidase levels. In fact, a high response of the seminal vesicles was observed in men with the highest basal serum testosterone levels (0.45 *** 0.17; coefficient of regression *** standard error; P <0.018). However, a high response in terms of seminal acid phosphatase ( P <0.004) or α‐glucosidase ( P <0.037) was observed in men with low basal serum testosterone levels. In conclusion, in the normal men, true‐corrected fructose and acid phosphatase but not α‐glucosidase in semen increased after duplicate androgen stimulation. An absence of response was observed in cases with history of STD/leukocytospermia or hypoandrogenism.
