We analyzed the effect of X-rays on the number of recoverable germ cells in female rat fetuses irradiated at three different times of gestation: 14 days (oogonia), 16 days (leptotene) and 18 days (zygotene). Our results show that irradiation significantly decreases the number of germ cells, and increases the incidence of synaptonemal complex fragmentation. The different sensitivity of the germ cells to irradiation could depend on the meiotic stage at the time of irradiation.
