Morphology of sustentocytes (Sertoli cells) with premature aging caused by light desynchronosis

The effect of 30-day dark deprivation (light-dark cycle 24/0 h, artificial illumination 300 Lux) on the morphofunctional state testes was studied using morphological and morphometric analysis histological preparations white mongrel male rats 4 months age. level follicle-stimulating hormone in blood serum assessed by enzyme immunoassay. It found that increases serum. Morphological changes were characterized a decrease area Sertoli cells their nuclei, thickness spermatogenic epithelium. hormonal background corrected administration exogenous melatonin for 14 days.
