Age-Related Changes in Penile Erections and Circulating Testosterone in Middle-Aged Male Rats
This symposium has documented a variety of neural and endocrine changes associated with the process of aging. The present chapter focuses on a specific behavioral consequence of these neuroendocrine changes. The behavior is penile erection. It has long been recognized that the erection response in human males declines with increasing age although this was first described systematically by Kinsey, Pomeroy and Martin (1948). Yet, the factors which account for the decline are poorly understood. One possible factor is testicular dysfunction, and innumerable sages, alchemists, and doctors have attempted to restore potency in aging men by administering testicular products, with varying degrees of success.
