Abstract/Description
Twenty-six 75-day-old, ovariectomized Long-Evans female rats were randomly divided into two groups of ten and one group of six animals. The ten Group I Ss received, in consecutive treatment periods, 2 mg progesterone (P-2) daily, 2 mg testosterone propiorate (TP-2) daily, TP-2 daily plus P-2 every fourth day, and P-2 every fourth day. The ten Group II Ss received, in consecutive treatment periods, P-2 every fourth day, and 4 mg dihydrotestosterone (DHT-4) daily plus P-2 every fourth day. Both...

The ten Group I Ss received, in consecutive treatment periods, 2 mg progesterone (P-2) daily, 2 mg testosterone propiorate (TP-2) daily, TP-2 daily plus P-2 every fourth day, and P-2 every fourth day. The ten Group II Ss received, in consecutive treatment periods, P-2 every fourth day, and 4 mg dihydrotestosterone (DHT-4) daily plus P-2 every fourth day. Both Groups I and II were tested for female sexual behavior. A significant increase in the lordosis response was observed only in Group I Ss after receiving TP-2 plus P-2 every fourth day. Group III Ss were tested for male sexual behavior after receiving DHT-4 daily. Male sexual behavior increased significantly after DHT-4 treatments. It was concluded that progesterone exerts a facilitatory effect on female sexual behavior only when the Ss have been previously primed with an aromatizable androgen and that dihydrotestosterone is capable of inducing male sexual behavior in female rats.
