Sexual impotence in the male.

One of the earliest serious medical studies of the subject from the anatomical, physiological, emotional, and psychological points of view. In the second edition (1887) retitled Sexual impotence in the male and female, the author added almost 50 pages on women's issues covering anatomical, physiological, and psychological reasons for absence of sexual desire in women.
