[Histoenzymatic study of postnatal development of the rat ovary, follicular atresia and interstitial gland].

In our experiment, we investigated histoenzymatic activity od postnatal development of rat ovary, specially the main metabolic process--steroidogenesis. We noticed, that during early folliculogenesis great amount of follicles are eliminated by atresia. Atresia also plays very important role in forming of interstitial gland. Interstitial gland which is found in ovary of 14 days old rat ovaries, morphologically and enzymatically differs from the structure observed on older animals. We concluded, that ovary of 14 days old rat is not developed but ovary of 21 days old rat seems to be morphologically and histochemically well developed.
