title: [Effects of prolonged low-dose gamma irradiation on testes of rats].
abstract: Dose-dependent characteristics of rat testicular cytosol androgen reception at varied terms after prolonged whole-body gamma-irradiation (0.1, 0.25 and 0.5 Gy at dose rate of 5.83 x 10(-7) Gy/s) coupled with an electron microscopy morphological characteristics of Sertoli cells. Leydig's cells and other populations of testicular cells, were examined. Analysis of the data obtained suggests the existence of gamma-sensor in brain of mammals, that involved on hypothalamic-pituitary-testicular levels in realisation of radiation stress suppression of Sertoli cell functions at a relatively "low" (0.1-0.5 Gy) doses by means of hypothalamic releasing factors and, therefore pituitary gonadotropins hypersecretion.
