Consider the steep decline in sex that parents of young children often experience because of sheer exhaustion. Life-history theory suggests a similar type of equation happens on a specieswide scale: energy either goes to raising the young or making more young ones. “Collectively, these data provide the most direct support to date that the biology of human males reflects a trade-off between mating and parenting effort,” claims the study.
