THE REGULATION OF THE HYPOPHYSIS BY THE TESTICLE, AND SOME PROBLEMS OF SEXUAL DYNAMICS

Abstract
Parabiosis of an infantile [female] rat with an infantile castrated rat induced precocious sexual maturity in the former within a few days after junction. Testicular implantations (adult or infantile) into the castrate partner prevented precocious maturity in the [female] partner when the castrate was a [male], but were ineffective when the castrate was a [female].
