[The reproductive function of male rats in the late periods after x-ray irradiation]. / Reproduktivnaia funktsiia samtsov krys v otdalennye sroki posle rentgenovskogo oblucheniia.

ABSTRACT

Reproductive function in male rats was studied in 1, 3 and 6 months after X-ray irradiation of doses of 2 and 3 Gy. It has been established that long-term effects of irradiation at a dose of 3 Gy are manifested through decrease in spermatozoa content in the epididymis and reduction of nucleic acid and protein content in the testes. Fertility of male rats under study significantly lowered shortly after irradiation and full recovery of fecundating ability was observed 6 months later. The effect of irradiation with a dose of 2 Gy was less pronounced.
