title: [The gametotoxic effect of antenatal exposure to thiotepa in mice].
abstract: ThioTEPA was injected intraperitoneally into female 101/H and CBA mice on day 12 of pregnancy at a dose of 2.5 mg/kg body weight. As a result, the number of prospermatogonia in 19-day-old male fetuses decreased to 78.8% in 101/H mice and to 63.7% in CBA mice. The gametotoxic effect on the male offspring (F1) in 101/H mice treated with thioTEPH included the significant decrease in the number of spermatogonia A, spermatocytes I at preleptotene and pachytene, as well as of spermatids at the stage 7 of development. Interstrain differences are described in the intensity of spermatogenesis in the mature intact animals and in regeneration capacity of gonads after prenatal thioTEPA administration.
