Abstract
The sexual dimorphism of the submaxillary glands of more than 550 male and female mice was studied in relation to (a) differences in weight, tubule diameter and histology of the normal adult glands, (b) the time and manner of the onset of sex differences in relation to growth and reproductive maturity, and (c) the effects of various sex hormones on the glands. It was found in adult mice that significant differences existed between the sexes in weight, tubule diam. and histology. These differences arose in rough parallelism to reproductive maturity and responded strongly to the presence or absence of male hormone and weakly to the presence or absence of female hormone.
