Experimentally induced true hermaphroditism in genetically female fowl

Summary

Two types of hermaphroditism were experimentally induced in genetically female fowls by grafting of embryonic testes in embryos. Of the 27 hermaphrodites observed during the 8 months after hatching, 20 possessed a right testis and a left ovary and 7 a right testis and a left ovotestis. The testes and ovotestes contained seminiferous tubules with a more or less developed germ cell complement, attaining in many cases the early spermatid stage. The interstitial tissue was poorly functional, as shown by the absence of male secondary sex characters. The ovary or ovarian part of the ovotestes possessed numerous small ovarian follicles. The female arrangement of the plumage and the absence of spurs demonstrated the secretion of oestrogens. A mechanism is proposed for explaining this partial masculinization of genetically female gonads, a phenomenon which occurs during the period of embryonic sex differentiation, and is responsible for this experimental true hermaphroditism.
