What indigenous men in Bolivia can tell us about BPH

INDIGENOUS men in the Bolivian Amazon may hold a lesson for those in Western countries tempted to combat ageing with testosterone supplements, researchers say.

A study of 350 Tsimane men aged between 28 and 89 shows they have less than half the prevalence of benign prostatic hyperplasia (BPH) seen in the US or UK.

They also have lower testosterone levels – but those with high levels of the hormone have larger prostates.

The Tsimane, who live in the lowlands of Bolivia, have a village-based lifestyle centred on hunting, gathering, fishing and small-scale horticulture, the researchers say.
