SPONTANEOUS INTERSEXUALITY IN THE RAT

Abstract
Within a period of 2 yrs., 8 inter-sex rats of a peculiar type have appeared spontaneously in our rat colony. Externally they possess [female] characteristics exclusively, internally small testes are present but no other sex organs whatever. Histologically, the testes show a distinct condensation of interstitial tissue surrounding the tubules, in 1 animal structures resembling corpora lutea were imbedded in the testes; adrenals and hypophyses were apparently normal.
