Love is blind

We have all heard the old wives' tale that masturbation can make you go blind. Well how about sex? For one man it was true -- he went temporarily blind every time he climaxed during sex.

Love is blind

True sex story

In a Discover Magazine blog written by two PhD students at UC Berkeley, they uncovered the story from the PubMed database. The original report was published by the Department of Ophthalmology at Glostrup Hospital and the University of Copenhagen in Denmark. It stated that the man's temporary blindness was caused by vasoconstriction -- the narrowing of blood vessels by muscles in their walls .

"Hypothetical mechanisms of transient monocular visual loss in our patient include vasoconstriction or embolism in the arterial blood supply of the eye," the report read. "The repeated and completely transient nature of our patient's symptoms supports the fact that embolism was not involved."

Thankfully for the man, doctors treated him with medication that widened his blood vessels and relieved his symptoms.
