vaginismus

vaginismus, involuntary muscle spasm that closes the opening to the vagina in the female reproductive tract. The spasm may be so intense that the vagina seems pathologically obstructed. Vaginismus is a sexual dysfunction resulting from physiological factors, such as sexual trauma, sexual abuse, or anxiety experienced at the prospect of sexual intercourse. Vaginismus can totally prevent coitus or make it extremely painful, a condition known as dyspareunia. Treatment includes counseling and exercises to improve voluntary control of the vaginal muscles.
