Not only is the tone of the voice often different, but there is reason to suppose that this rests on a basis, of anatomical modification.  At Moll’s suggestion, Flatau examined the larynx in a large number of inverted women, and found in several a very decidedly masculine type of larynx, or an approach to it, especially in cases of distinctly congenital origin.  Hirschfeld has confirmed Flatau’s observations on this point.  It may be added that inverted women are very often good whistlers; Hirschfeld even knows two who are public performers in whistling.  It is scarcely necessary to remark that while the old proverb associates whistling in a woman with crowing in a hen, whistling in a woman is no evidence of any general physical or psychic inversion.

As regards the sexual organs it seems possible, so far as my observations go, to speak more definitely of inverted women than of inverted men.  In all three of the cases concerning whom I have precise information, among those whose histories are recorded in the present chapter, there is more or less arrested development and infantilism.  In one a somewhat small vagina and prominent nymphae, with local sensitiveness, are associated with oligotrichosis.  In another the sexual parts are in some respects rather small, while there is no trace of ovary on one side.  In the third case, together with hypertrichosis, the nates are small, the nymphae large, the clitoris deeply hooded, the hymen thick, and the vagina probably small.  These observations, though few, are significant, and they accord with those of other observers.[170] Krafft-Ebing well described a case which I should be inclined to regard as typical of many:  sexual organs feminine in character, but remaining at the infantile stage of a girl of 10; small clitoris, prominent cockscomb-like nymphae, small vagina scarcely permitting normal intercourse and very sensitive.  Hirschfeld agrees in finding common an approach to the type described by Krafft-Ebing; atrophic anomalies he regards as more common than hypertrophic, and he refers to thickness of hymen and a tendency to notably small uterus and ovaries.  The clitoris is more usually small than large; women with a large clitoris (as Parent-Duchatelet long since remarked) seem rarely to be of masculine type.

Notwithstanding these tendencies, however, sexual inversion in a woman is, as a rule, not more obvious than in a man.  At the same time, the inverted woman is not usually attractive to men.  She herself generally feels the greatest indifference to men, and often, cannot understand why a woman should love a man, though she easily understands why a man should love a woman.  She shows, therefore, nothing of that sexual shyness and engaging air of weakness and dependence which are an invitation to men.  The man who is passionately attracted to an inverted woman is usually of rather a feminine type.  For instance, in one case present to my mind he was of somewhat neurotic heredity, of slight physical development, not sexually attractive to women, and very domesticated in his manner of living; in short, a man who might easily have been passionately attracted to his own sex.
