More on Cervical Orgasm
Posted on 09/20/2016
"The orgasm itself has been misunderstood. In 1973, Masters observed: "Many women certainly describe cervical pressure as a trigger mechanism for coital responsivity. These women can be and occasionally are handicapped sexually when such a trigger mechanism is removed surgically." Such orgasm has often mistakenly been referred to as "vaginal," and its existence has been challenged on the basis that the vaginal walls do not contain nerve endings. It has been supposed, however, that women who experience great satisfaction when sex involves deep vaginal penetrations, depend on some mechanism that lies outside of the vaginal walls themselves.
In fact, this internal orgasm is essentially a cervical orgasm caused by stimulation of nerve endings that intimately surround the cervix and attach to the upper vagina. In 1966, Masters and Johnson observed from their laboratory research that during internal (or vaginal) orgasm the muscle contractions in the outer third of the vagina are accompanied by rhythmic contractions of the uterus. Clark and Singer pointed out that the internally induced orgasm occurs when the penis presses hard and repetitively against the cervix, causing movements of the uterus and its broad supporting ligaments which stimulates the surrounding peritoneal membrane, which has pleasurable sensitivity.
Thus, for some women, the quality and intensity of orgasm (triggered by deep vaginal penetration) is related to the movement of the cervix and uterus. We propose that the loss of the cervix and uterus in addition to a major portion of the nerve bundles may have an adverse effect on sexual arousal and orgasm in women who previously experienced internal orgasm. For other women, however, orgasm is achieved mainly by the stimulation of the labia and clitoris alone (clitoral orgasm).
Therefore, the loss of the cervix and uterus may not cause any dysfunction. Evidence that women experience one or both types of orgasm, sometimes blended, have been reported; however, the percentage of women for whom the cervix and uterus are sexually important is unknown. Furthermore, none of the investigators in these studies have learned whether the cervix and uterus were important to the sexual response of the women being questioned.
Studies conflict on whether hysterectomy leads to sexual dysfunction. One study compared a regular hysterectomy with one where the cervix is left in place (supracervical surgery), finding that when the cervix is removed, there is a significant decline in sexual function while supracervical surgery did not cause significant changes. In contrast, a recent paper in the Journal of the American Medical Association concluded that the frequency of sexual activity increased and problems with sexual dysfunction decreased after hysterectomy.6 The impact of hysterectomy on sensation may be due to possible damage of the uterovaginal nerves by surgery to the pelvic floor and, to a greater extent, by total hysterectomy."
