title: The aging male reproductive system.
abstract: The frequency of sexual activity declines dramatically with age, but this cannot be attributed, with any degree of certainty, to the rather modest hormonal and spermatogenic changes observed with advancing age. Despite the development of intrinsic age-related defects at all levels of the hypothalamic-pituitary-testicular axis, reproductive capacity is maintained in most healthy elderly men.
