The study shows that the hard-core sex movies reduces blood flow to the visual cortex of healthy women, heterosexuals, blurring vision.
Dr. Gert Holstege, a uroneurologist at University Medical Center Groningen in the Netherlands, said the results suggest that when movies are hard core, sexual desire takes precedence over anxiety in the eyes of a woman.
"If you look, for example, on your computer and you have to write something, or whatever, then you have to do that specifically with care and watch what you're doing, because if not, it means making mistakes," he told the news media.
"But when you are watching sexually explicit movies, it is not necessary, because you know exactly what is
happening. It is not important that the door is green or yellow."
A dozen research participants, all in a hormonal contraceptive method, were watching three films: a documentary on marine life in the Caribbean, a soft-core porn film and a hard core porn film.
Using PET to look inside the brains of women, the researchers observed a decrease in blood flow to the visual cortex when participants were watching hard-core films, Holstege said.
The research results were published this month in the Journal of Sexual Medicine.
