| Abstract: | Male rats castrated on the first day of life were sexually excited by posturings of the same sex following androgen substitution in adults. In other words, genetic males exposed to a temporary androgen deficiency during sexual differentiation and maturation of the brain, but normal androgen levels in adulthood, had homosexual behaviour. The higher the androgen level during a critical differentiation phase, the stronger was the male and the weaker the female sexual behaviour during the post pubertal functional phase, irrespective of the genetic sex. |
