Sécrétions apocrines dans le tractus génital mâle: Roles potentiels dans la maturation des gamètes

Apocrine secretory vesicles have been observed in the lumen of several ducts of the male genital tract, namely the epididymis and vas deferens. Initially considered to be tissue-fixation artefacts, they are now recognized as genuine elements, which might play physiological roles in terms of sperm maturation. The aim of this review is to present these vesicles observed in various mammalian species and to describe their respective organization, content and putative roles.
