In researches on 402 rats Wistar, more than 1300 fruits and 1900 young rats posterities of the first generation are investigated reproductive function of the animals, subjected to unitary total gamma irradiation 60Со in not sterilizing doze 1 Gy (capacity of a doze 0,003sGy/s) for 10 day of their intra-uterine development (the period of a bookmark of reproductive system) or in various terms (1, 4-11 and 30-40 day) after radiating influence on sexual maturity females. Posterity females, irradiated antenatal, or posterity sexual maturity animals, pregnancy at which came in the first 11 day after an irradiation, defectively, and this inferiority is more expressed in postnatal ontogenesis at posterity on a parent line antenatal the irradiated animals.

Key words
Rats Wistar; irradiation of antenatal and sexual maturity ovaries; reproductive function; posterity.
