Abstract
Prostate sampled from three nutria males was processed for histological examination. It was found that, unlike terrestrial mammals, the capsula and conjunctive trabeculae not contain smooth muscle cells, so they do not participate in the evacuation of the content from gland during ejaculation. Glandular tubes from prostate of nutria present own-developed muscularis, similar to the arteries media, which allows an evacuation of secretions from each tube in part, so that evacuation of the contents of nutria prostate during ejaculation is made under a greater pressure than in terrestrial mammals. This particular mode of evacuation of prostate secretions appears to be a functional adaptation due to the fact that the nutria male performs the sexual act also in water, where conditions are totally different from those on land.
