Longevity in Caenorhabditis elegans reduced by mating but not gamete production

Abstract

THEORIES of life-history evolution propose that trade-offs occur between fitness components, including longevity and maximal reproduction1–3. In Drosophila, female lifespan is shortened by increased egg production4, receipt of male accessory fluid5 and courting6. Male lifespan is also reduced by courting and/or mating7. Here we show that in the nematode… (More)
