Researchers: Sleep Deprivation May Lower Male Libido, Cause 'Sexsomnia'

The Brazilian sexual health specialist, Professor Monica Andersen, says the increasing pace of the modern world is taking a toll on hours of sleep and is having a direct knock-on impact on sex.

There is an increasing body of evidence showing those who don't sleep enough are suffering lower libidos and, in many cases, are also suffering erectile dysfunction.

And in a very few number of men, this lack of sleep is triggering a rare and disturbing condition called sleep sex, or sexsomnia, when their libido is heightened and they initiate sex while asleep.
