In the analysis of the problem these cases cannot be regarded as wholly insignificant. The details show that the subjects were clearly morbid. Therefore they have their value for the building up of a theory of sexual inversion upon the basis of inherited and active disease.

Their reproductive organs are perfectly differentiated on the masculine type; but they desire men instinctively, and are inclined to express their bias by assuming characters of femininity.
