| Answer» B. Eugen Steinach | |
|
Explanation: Eugen Steinach discovered the sex hormones in 1921. He conducted experiments in the transplantation of a male guinea pig's testes into a female and the castration of the male. The testes secretion, now known as testosterone, resulted in the female guinea pig developing male sexual behavior such as mounting the partner. This led Steinach to theorize that the gland's secretions were responsible for sexuality. |
