The greater predominance of the sexual system in women on the psychic side is clearly brought out in insane conditions. It is well known that, while satyriasis is rare, nymphomania is comparatively common. These conditions are probably often forms of mania, and in mania, while sexual symptoms are common in men, they are often stated to be the rule in women (see, e.g., Krafft-Ebing, _Psychopathia Sexualis_, tenth edition, English translation, p. 465). Bouchereau, in noting this difference in the prevalence of sexual manifestations during insanity, remarks that it is partly due to the naturally greater dependence of women on the organs of generation, and partly to the more active, independent, and laborious lives of men; in his opinion, satyriasis is specially apt to develop in men who lead lives resembling those of women. (Bouchereau, art. "Satyriasis," _Dictionnaire Encyclopédique des Sciences Médicales_.) Again, postconnubial insanity is very much commoner in women than in men, a fact which may indicate the more predominant part played by the sexual sphere in women. (Savage, art. "Marriage and Insanity," _Dictionary of Psychological Medicine_.) Insanity tends to remove the artificial inhibitory influences that rule in ordinary life, and there is therefore significance in such a fact as that the sexual appetite is often increased in general paralysis and to a notable extent in women. (Pactet and Colin, _Les Aliénés devant la Justice_, 1902, p. 122.) Näcke, from his experiences among the insane, makes an interesting and possibly sound distinction regarding the character of the sexual manifestations in the two sexes. Among men he finds these manifestations to be more of a reflex and purely spinal nature and chiefly manifested in masturbation; in women he finds them to be of a more cerebral character, and chiefly manifested in erotic gestures, lascivious conversation, etc. The sexual impulse would thus tend to involve to a greater extent the higher psychic region in women than in men.
