Abstract
Abstract The sexual behavior of 10 adult long-term castrated rhesus monkeys before and after treatment with 19-hydroxytestosterone (19-OH-T) was compared. Only the rate at which males contacted females increased significantly after treatment. The sexual behavior of these castrates was also compared with that of 8 untreated intact controls. Levels of estradiol-17β (E2) and luteinizing hormone (LH) in peripheral plasma were determined by radioimmunoassay both before and after 19-OH-T treatment. After treatment, there was a significant increase in E2 levels and a significant decrease in LH levels. Only the 5 males that had showed the ejaculatory response before treatment displayed it while undergoing treatment. These males had the lowest E2 level during treatment whereas the 5 males that had failed to achieve intromission and ejaculation had the highest levels of E2. The mounting rate correlated negatively with the level of E2 in the blood.
