Course and Duration.—This is an affection of indefinite duration; unless relieved it may continue through years of discomfort and misery. Cases are reported as lasting twenty-five or thirty years. There is a mild form sometimes occurring among the recently married which will either disappear of itself or yield to simple treatment. More generally, the discomfort and pain continue unless successfully treated, and in well-marked cases attempts at intercourse increase the suffering; there is nervous exhaustion, the health breaks down in consequence and from what has been called "the disappointment of nature under an unfulfilled function."
PATHOLOGY.—In certain morbid conditions the nerves distributed about the outlet of the vagina may possess such a high degree of irritability that a foreign substance coming in contact with them will cause contraction and spasm of the tissue in which they are distributed and connecting muscles.
Sinéty13 is of the opinion that "in milder forms of the disorder the constrictor vaginal muscles alone may be the seat of the spasm; but more generally all of the muscles forming the floor of the perineum, the constrictors of the vulva and vagina, muscles of the anus and of the urethra, superficial and deep," in truth, "all the muscles of the region," can "simultaneously be the seat of spasm." Emmet14 considers vaginismus as kindred to neuralgia, for the reason that it more frequently occurs among anæmic and excessively nervous women, and those who have in some manner overtaxed their nervous systems, the locality being determined as it were by accident, and that only in exceptional instances can there be any local exciting cause. Thomas15 says that it is curious to perceive how, from different standpoints regarding the pathology, "both parties were led to the same surgical resource."

The author's own observation will not permit of his ascribing the majority of cases wholly to morbid constitutional conditions, to the exclusion of local lesions. The reason of his belief is that the greater number of cases he has observed have been treated and cured by surgical measures, having in view the relief of morbid conditions of some pelvic structures.
DIAGNOSIS.—The diagnosis is attended with no difficulty, as there is no other affection presenting similarities.
PROGNOSIS.—Sims remarks that he knows of "no serious trouble that can be so easily, so safely, and so certainly cured." Scanzoni, Tilt, and others, who hold different views as to the pathology and means of cure, express themselves as favorably regarding prognosis. Thomas has never met with a case that he could not relieve or cure. Nearly all gynecologists are of the opinion that a favorable prognosis is warrantable in the majority of cases.
TREATMENT.—In cases where it seems quite difficult to ascertain the etiology and pathology a palliative course may at first be pursued, such as vaginal injections of acetate of lead or borax in warm water (drachm j ad pint j), to which may be added carbolic acid or laudanum or the wearing of the vaginal rest or dilator, and total abstinence from any attempts at coition. If the chief cause seems to be in some constitutional trouble, then as complete physiological rest as possible should be enjoined. With this in view, all attempts at sexual intercourse must be discontinued, as it will keep up nervous suffering and local pain and discomfort. The vaginal dilator of Sims secures a rest by keeping the walls apart; it also dilates and benumbs the parts, thus rendering them more tolerant of a foreign body. With every mode of treatment or in cases occurring from any cause the vaginal dilator is required; this is to be worn for two or more hours at intervals of six to twelve hours, according to the degree of tolerance with which it is borne. It should be smeared previous to insertion with some soothing lubricant, as iodide of lead and glycerin (drachm j ad ounce j) or atropia and vaseline (gr. ij ad ounce j) or stramonium ointment. Vaginal suppositories containing morphia, extract of opium, belladonna, hyoscyamus, or stramonium will usually prove of great benefit as local sedatives. In some instances suppositories containing five to ten grains of iodoform may be of service. Copious vaginal injections of warm or hot water alone are beneficial in the majority of cases, as they wash away irritating discharges that aggravate the disease, and by lessening the congestion frequently do away with the necessity of surgical operations.
