BBC: Men's genes 'may limit lifespan'

Men carry the seeds of their own destruction in the genes present in their sperm, research suggests. Scientists working on mice have highlighted a specific gene that, although carried by both sexes, appears to be active only in males.

They believe it allows males to grow bigger bodies - but at the expense of their longevity.

The researchers said in nature males tended to concentrate resources on building a large body, because strength and bulk help them fight for mating opportunities with females. In contrast, females tended to conserve energy for breeding and providing for their offspring.
