Most of the age-related changes to the male reproductive system cannot be prevented or reversed. Men can, however, boost their sexual health by eating healthy meals, exercising regularly and having sex regularly during their middle-age years.
Some of the common age-related changes in the male reproductive system include reduced sperm production, erectile function and changes within the testicular tissue. Unlike women, who experience rapid changes during the course of several months (particularly during menopause), the age-related changes in men happen gradually in a longer period in a process sometimes described as andropause. The bulk of the changes occur within the male testes. Primarily, men experience a decrease in tissue mass and slightly lowered levels of testosterone. The tubes responsible for carrying sperm may stiffen, causing a decrease in sperm production. The male prostate gland also enlarges with age, and this may lead to benign prostatic hypertrophy, a condition that causes problems with male urination and ejaculation. Men also experience an increased risk of prostate cancer or prostatitis with age, according to Medline Plus. A decrease in sexual drive and a longer refractory period is common with some men. However, most men can still enjoy a healthy sexual relationship and have children well into their 80s despite the changes in their male reproductive systems.
