RADIOSENSITIVITY OF OOGONIA AND OOCYTES IN THE FOETAL RAT

Journal Article · · Inter. J. Radiation Biol.
Pregnant rats were exposed to doses of 25 to 2 x 100 r of x rays at varying times between the 13th and the 2Oth days after insemination. Female offspring were killed at 25 days post partum, and the number of oocytes was estimated from serial sections of the ovaries. The population of oocytes in the irradiated ovaries was found to depend both on the dose of x rays administered and on the fetal age at the time of exposure. The period of maximum radiosensitivity, which occurred on the l5th day of gestation, was found to coincide with a high rate of mitotic division of oogonia. (auth)
