Advancement of Sexual Maturation in Male Rats by Pituitary Transplants

Abstract

Male rats are born with a fused balano-preputial skinfold. The cleavage of this skinfold is dependent on androgens and normally occurs about Day 40-45 of life. In the present study the relationship between skinfold cleavage and androgen was reexamined with particular attention to the possible use of this cleavage as an easy and nontraumatic index of sexual maturation.
