Can too much masturbation or sex cause stroke?

Sex: Masturbation and sex are not frequent causes of stroke in young people. In patients of advanced age, it may be somewhat more likely.

Stroke: A stroke is caused by a blockage or a leak in a cerebral artery. I suppose if either masturbation or sex were vigorous enough to raise the blood pressure or cause certain cardiac beat abnormalities it would be possible but not extremely likely
