"It's not the most romantic ending a couple can imagine,"
says Dr Aristomenis Exadaktylos, author of a study of 11 years of admissions to his hospital in Bern, Switzerland.
"It happened to my husband and myself one night.
He literally could not withdraw i.e. was 'stuck'.
I attributed it to the intensity of the vaginal muscle response during orgasm."
"I remember hearing a story when I was 14 or 15 about an American airman who got stuck inside a lady
and they had to get an ambulance and get them to a hospital to get them parted,"
Dr John Dean, a senior UK-based sexual physician, says that both accounts are credible examples of a rare phenomenon :
that doctors sometimes call :
"penis captivus" (captive penis).
"When the penis is in the vagina it becomes increasingly engorged," he says,
"The muscles of the woman's pelvic floor contract rhythmically at orgasm.
While those muscles contract the penis becomes stuck and further engorged."
In a 1933 manual of gynaecology, the author Walter Stoeckel speculated that penis captivus only affected couples :
engaged in illicit sex, the fear of detection presumably contributing to the force of the woman's muscular spasm. ::LOL::
