Penis captivus

Penis Captivus

Penis captivus (pronunciation: /ˈpiːnɪs kæpˈtiːvəs/) is a rare occurrence during sexual intercourse when the muscles in the vagina clamp down on the penis much more firmly than usual (a form of vaginismus), making it impossible for the penis to withdraw from the vagina.

Etymology

The term "penis captivus" is derived from Latin, where "penis" refers to the male genital organ and "captivus" means captive or trapped, thus literally translating to "captive penis".

Related Terms

Coitus Reservatus: A form of sexual intercourse where the male attempts to avoid ejaculation.
Coitus Interruptus: A method of contraception where the penis is withdrawn from the vagina before ejaculation.
Vaginismus: A condition involving a muscle spasm in the pelvic floor muscles, which can make sexual intercourse painful or impossible.

Occurrence

Penis captivus is considered a rare condition. It is often associated with the myth of vagina dentata (toothed vagina), but it is a real, though extremely rare, medical phenomenon. It is more likely to occur when the woman experiences vaginismus, a condition where the muscles of the vagina involuntarily or persistently contract.

Treatment

In most cases, penis captivus resolves itself quickly and without any lasting effects. However, in rare cases, medical intervention may be required. This can involve the use of muscle relaxants or, in extreme cases, surgical intervention.
