This excitement from congenital or accidental dispositions, may affect the ovaries; to prove this we have only to consider that their development exactly follows that of the venereal sense: that at forty-five years they begin to diminish in size, and finally they disappear: their removal or destruction too is always attended with the extinction of venereal desires. The respective size of the veins and arteries of the ovaries has been mentioned by some authors as a cause of salacity: the amorous ardor of animals, say they, is much greater, when the veins of the ovaries are smaller and fewer than the arteries. Haller found that the last-named vessels were very much developed in a female whose temperament was extremely amorous. Different alterations in the ovaries have been found in those affected with nymphomania. Bosset, Blancard, Vesalius, Riolan, Mangel, Dimmerbroede, Riviere, Lieutaud &c. have observed cases of this. De Blegnay states that one of the girls confined at the Salpetrière, and who had been affected several times with furor uterinus, was once seized so violently that it was necessary to tie her. This unfortunate girl perished by suffocation, while struggling to extricate herself. On opening the dead body the left ovary and Fallopian tube were found much diseased. The removal of the ovaries has been performed successfully to appease excessive uterine ardor; a swineherd, irritated by the conduct of his daughter, extirpated these organs and thus extinguished her passions. The ovaries however have been extirpated several times on account of disease. The operation has been performed on several women and with success by Dr. Sacchi of Italy, and Dr. D. L. Rogers of New York. The usual effects in those who are fortunate enough to survive, are a wasting of the mammæ and a perfect indifference to the act of venery (_Bulletin therapeutique_, vol. iv., p. 313.)
