A wild common shrew (Sorex araneus) with an XXY sex chromosome constitution

J B Searle. J Reprod Fertil. 1984 Jan.

Abstract

An adult male common shrew with an XXY sex chromosome constitution was found in a natural population. The external appearance of the animal and size of the accessory glands were normal but the testes were as small as those of immature shrews. Histological preparations of the testis revealed seminiferous tubules containing only one type of cell, probably Sertoli cells, and interstitial cell hyperplasia.
