Voluntary medical male circumcision could impact Zimbabwe's HIV epidemic in the coming years, and this investment may save costs in the longer term. These findings were reported by Jessica McGillen of Imperial College London and colleagues on July 18 in the open-access journal PLOS ONE.
Polygyny has been more common among relatively egalitarian low-tech horticulturalists than in highly unequal, capital-intensive agricultural societies. This surprising fact is known as the 'polygyny paradox,' and a new study from the Santa Fe Institute's Dynamics of Wealth Inequality Project provides a possible resolution of the puzzle.
According to a new National Institutes of Health-funded study, it is not destiny that brings two fruit flies together, but an evolutionary matchmaker of sorts that made tiny adjustments to their brains' mating circuits, so they would be attracted to one another while rejecting advances from other, even closely-related, species. The results, published in Nature, may help explain how a specific female scent triggers completely different responses in different male flies.
Democrats, who generally have a more liberal take on sexual matters, were least likely to use an adultery dating service, while members of the conservative Libertarian party had the greatest tendency to do so. This is according to an analysis of leaked user data from Ashley Madison, a website that connects married people who want to cheat on their partner.
New research from the Oxford Internet Institute, University of Oxford has found that Internet filtering tools are ineffective and in most cases, were an insignificant factor in whether young people had seen explicit sexual content.
The numerous high-profile men who have recently been accused of sexual harassment may not have been simply exercising their power. Instead their behavior could be related to feeling insecure and believing that others find them ill-suited to or undeserving of their dominant position. This is according to new research in Springer's journal Sex Roles, which was led by Leah Halper of Ohio University and The Ohio State University, and Kimberly Rios, also of Ohio University in the US.
Seeking abortion medications online can be a response to clinic access barriers both in states with and without restrictive abortion laws and can occur when self-managed abortion is preferred over clinical care. Researchers found that online options either offer information about how to correctly and safely use abortion medications or sell the required medications, but not both, and lack of trusted online options can delay care and lead to consideration of ineffective or unsafe alternatives.
Young adults who had parents incarcerated during childhood do not receive timely healthcare and have more unhealthy behaviors, Lurie Children's researchers find.
A new Aggressive Behavior study has examined alcohol's 'in the moment' effects on sexual aggression, or the acute effects of alcohol on men's decisions about how to respond to sexual refusals in a dating simulation.
Status symbols, like a luxury car or brand-name denim, may not function any better than their lower-status counterparts, but they do convey a message about the owner's position on the social ladder. A new study led by Gideon Nave of the University of Pennsylvania's Wharton School found that a single dose of testosterone was enough to boost men's preference for higher-status goods, pointing to a biological basis for consumer behavior.
