Definition of Vaginismus:

Vaginismus is an involuntary spasm of the muscles surrounding the vagina. The spasms close the vagina.

Causes, incidence, and risk factors:

Vaginismus is considered a disorder of sexual dysfunction. It has several possible causes, including past sexual trauma or abuse, psychological factors, or a history of discomfort with sexual intercourse. Sometimes no cause can be found.

Vaginismus is an uncommon condition. The exact number of women who have this problem is unknown.

Women with varying degrees of vaginismus often develop anxiety regarding sexual intercourse. The condition causes penetration to be difficult and painful, or even impossible. However, this does not mean the woman cannot become sexually aroused. Many women may have orgasms when the clitoris is stimulated.
