Centripetal Notion

For the ladies:

The researchers compared a group of marsupials whose females who were only allowed to mate with one male and another where they had many partners.

“The result was that survival of babies with promiscuous mothers was almost three times as high as those in the monogamous group,” Fisher said.

Despite the advantages to the species from free love, males usually died after a short and intense single mating season due to exhaustion and aggressive encounters with other males.

Females got off lightly, usually living to breed for a second or third year.

And the dudes:

• Sex and death are common variables in epidemiology, but the relation between them has been little studied
• In this cohort study, mortality risk was 50% lower in men with high frequency of orgasm than in men with low frequency of orgasm; there was evidence of a dose-response relation across the groups
• The question of causation is complex, as with all observational epidemiological findings; several explanations are possible, but the evidence for causation is as convincing here as in many areas where causation is assumed
• These findings contrast with the view common to many cultures that the pleasure of sexual intercourse may be secured at the cost of vigour and wellbeing
• If these findings are replicated, there are implications for health promotion programmes
