Overview
The pathophysiology of dyspareunia can be described based on the underlying cause. For example, estrogen deficiency causes atrophic vaginitis or ectopic uterine tissues in endometriosis causes dyspareunia. Physocholoigacal problems can cause dyspareunia.
Pathophysiology
Vaginismus: This is the result of a conditioned reflex of the pubococcygeus muscle, which is sometimes referred to as the 'PC muscle'. The reflex causes the muscles in the vagina to tense suddenly, which makes any kind of vaginal penetration -- including sexual penetration -- either painful or impossible.
Endometriosis:The exact pathogenesis of endometriosis is not clear; several theories have been set forth. The Sampson theory of retrograde menstruation, the coelomic metaplasia theory, and the lymphatic and vascular dissemination theory explain the implantation and invasion of the endometrial tissue outside the uterine cavity. Immunologic factors and genetic factors are also thought to play a role in the pathogenesis of endometriosis.
