Does being male affect blood clot risk?

Men genetically predisposed to high testosterone have an increased thromboembolic risk, study shows

Being more macho may have advantages, but prevention of blood clots isn’t one of them, according to a study linking endogenous testosterone to thromboembolism.

The UK researchers used data from 392,000 men and women to see whether having genes predisposing to higher testosterone levels resulted in more or fewer thromboembolic events.
