Pregnant CBA mice were injected i.p. with 20 .mu.Ci of 35S on day 10.5 of gestation and allowed to go to term. No mortality was observed in treated animals. However, a slight reduction in the number of fertile matings was noted in 35S group. But the reduction was statistically insignificant. A significant decrease in litter size was noted in 35S-treated group. While the litter size was 7.5/.female. in the control, it was 5.9/.female. in 35-group. The reduced litter size may be due to 35S-induced prenatal mortality. A further reduction in litter size was noted at weaning. This reduction was due to a significant increase in the neo- and postnatal mortality of F1 progeny in the treated group. There was no effect of 35S on the sex ratio and body weight of F1 progeny.
