Monday Sep 15, 2008 (foodconsumer.org) -- It happens that having sex could result in some unexpected adverse effect.  A 35 year-old woman suffered a stroke paralyzing many functions of her left side after having sex with her boyfriend, according to a case report published in the Journal of Stroke and Cerebrovascular Disease.

Minutes after having sexual intercourse, the woman suddenly felt her left arm became weak and her speech became slurred and feeling on the left side of her face got lost.

Doctors said the stroke could be due to a number of reasons including birth control pills, a venous blood clot, sexual intercourse and a heart defect.

Birth control pills increase the risk of blood clots. Sexual intercourse can cause pressure changes in the heart and enable the clot to travel through the hole from the right atrium to the left one.

The woman got a stroke score of 13 when admitted to Loyola University Medical Center and her stroke score dropped to 3 after 12 hours and to 1 after two months, according to a press release by the medical center.  

Her only symptoms at the time of writing the case report was a slight weakening of her facial muscle and impairment of her left hand.
