[Aging and sexuality--seen by andrologists (author's transl]

As the sexuality of the aged man is concerned it can be said, that the potentia generandi may be maintained up to a very advanced age if there is no restriction because of illness or injury and that, on the other hand, the potentia coeundi will constantly decrease mainly after the age of 60. However, it is possible that in the case of regular sexual activity during the middle life and of a adequate partnership the ability of practicising a satisfaying coitus for able partners may exist during the 7th and 8th decade of life.
