Low testosterone a stroke risk

Low plasma testosterone (T) and dihydrotestosterone (DHT) are “independent and substantive predictors” of incident stroke in older men, say WA researchers.

Their population-based study of 3,700 men aged 70 to 89 shows those in the highest compared with the lowest quartile for T and DHT had roughly half the risk of a first stroke, with a mean follow up of nearly seven years.

The finding held even after adjusting for age, cardiovascular risk factors, anticoagulation therapy and head injury on admission for stroke.
