Testicular function in sexually mature rats was studied following ligation of the vas deferens, corpus epididymis, and vasa efferentia. Ligation of the corpus epididymis and vasa efferentia significantly (p less than .01) reduced testicular weight, but did not markedly affect the weights of the ventral prostate and seminal vesicle, nor did it markedly alter plasma testosterone levels. The weight of the epididymis head was significantly (p less than .01) increased in the corpus epididymis ligated group, as was the weight of the epididymal tail in vasoligated animals. The data suggest that ligation at the 3 sites does not affect the endocrine function of the testis. The influence of sperm stasis on testicular function is discussed.
