The sexual impulse may be present in cases in which the ovaries are entirely wanting. Thus, _Hauff_ reports the case of a young girl who had no ovaries, but was nevertheless excessively addicted to masturbation. _Gläveke_ speaks of a puella publica in whom the uterus and the ovaries were entirely absent, but who asserted that she experienced during coitus active sexual sensation. Both _Kussmaul_ and _Puech_ report similar experiences in cases of absence or arrested development of the uterus. As regards the effect on the sexual impulse of the operation of oöphorectomy, most authors state that no change occurs; still, there remain many who express the opposite opinion. From the collective summary of cases bearing on this question made by _Gläveke_, it appears that after extirpation of the ovaries the sexual impulse remains unchanged in the great majority of cases, or at most is but slightly diminished in intensity. _Hegar_ states that he has often witnessed a diminution of the sexual impulse after oöphorectomy, but that this decline is by no means constant, indeed he states that one of his patients assured him that in her case no decline in the intensity of the sexual impulse had followed the operation. Similarly variable reports were the experience of _Schmalfuss_. In one case he found there was but little sexual inclination; in one case, disinclination; in one case disinclination at first, followed by a return of inclination. _Bruntzel_ reports that in four patients subjected to oöphorectomy, in two cases the sexual impulse persisted, but in the remaining two it was extinguished. _Köberle_ is of opinion that sexual inclination diminishes as a result of this operation. _Peaslee_, on the contrary, asserts that the patients remain striking examples of womanhood, in whom all the qualities peculiar to their sex are preserved. _Péan_ observed as a rule no difference in the sexual impulse to result from this operation, but he considers that the patients are apt to describe in exaggerated terms the amount of sexual feeling that remains to them. In one case, _Spencer Wells_ observed after oöphorectomy an increase in sexual excitability; _Tissier_ had the same experience, and this author believes that in these cases the sexual impulse is generally preserved. On the other hand, _Bailly_ observed a case, in which both ovaries were removed on account of new growths, where the sexual impulse at first became excessive, and then completely disappeared. _Anger_ and _Goodell_ speak in the same sense.
