Because in the mouse some structurally abnormal spermatozoa can penetrate oocytes, we decided to determine whether mouse oocytes fertilized by spermatozoa with grossly misshapen heads are able to develop normally. We injected such spermatozoa from BA

The selective toxic effects of cadmium on the testes of eutherian mammals have been well documented. A single subcutaneous or intraperitoneal injection of cadmium (as CdCl/sub 2/) results in testicular necrosis in most eutherian species. Some compara

A predictably high incidence of true hermaphroditism (3%) among fetal BALB/cWt mice provided the opportunity for studying the cause of inherited hermaphroditism. G-banded liver metaphase chromosomes were analyzed from 20 fetal hermaphrodites and from

SUMMARY When female mice were caged in groups of thirty, regular oestrous cycles did not occur in the majority of animals. The vaginal smears of these mice were mucified and some remained so for 40 days. Cycles promptly returned when the mice were ca

SUMMARY 1. The action of progesterone on the development of the mouse ovum from the eight-celled stage to the blastula has been studied in vitro. 2. Concentrations of progesterone below 2 μg/ml. produced no observable effect, whereas some toxicity w
