[Morphofunctional characteristics of interstitial endocrine cells (Leydig cells) from testis and prostate of Orenburg goats in ontogenesis and under conditions of seasonal changes in their reproductive activity].
Dynamics of structural reorganizations of goat testicular Leydig cells and prostate was monitored in different periods of ontogenesis using light and electron microscopy. Morphological equivalents of endocrinocyte functional activity elevations were noted within the period from d 60 to 70 of embryogenesis, at puberty and in mature animals before the onset of mating period in mature animals. Endocrinocyte foetal population destruction occurs by the 1st postnatal month. Leydig cell maximum activity peak precedes structural and functional differentiation in prostate both at stages of ontogenesis and in periods of seasonal oscillations of reproductive activity.
