A UMass scientist has identified a gene, Nhlh2, that regulates body weight, physical activity levels, and sex behaviors in mice. The knockout mice are severely obese and exhibit reduced physical activity, illustrating the critical role of the gene in regulating appetite and exercise.
A study by Seth C. Kalichman found that HIV-positive men who were sensation seekers were more likely to have unprotected sex, regardless of alcohol use. Alcohol also predicted unsafe sex, independent of sensation seeking. The study suggests cognitive approaches can help improve risk reduction interventions for HIV-positive men.
A recent study by Emory University Health Sciences Center found that lower levels of social capital are associated with higher rates of sexually transmitted diseases. The research, which analyzed data from 48 US states, discovered that social capital is a significant predictor of infectious diseases including AIDS and STDs.
A community-based intervention implemented in Albuquerque from 1997-98 found that young gay men reported a 12% decrease in unprotected anal intercourse, reversing baseline increases. The study suggests that empowering communities to establish healthy environments with peer support can effectively reduce HIV risk behavior.
A recent study found that childhood sexual abuse is a top predictor for HIV infection in women, with those who suffered abuse at age 18 being seven times more likely to engage in high-risk unprotected sex. Women who experienced trauma also faced greater economic and social challenges, making them more vulnerable to further exploitation.
Researchers at San Francisco State University found that 74% of women wearing perfume with a synthetic pheromone experienced an increase in sociosexual behaviors, including kissing, affection, and sexual intercourse. The study concluded that the pheromone increased the attractiveness of women to men, leading to more romantic behavior.
A new analysis of 62 studies found that men and women agree on the seriousness of sexual coercion and propositions, but disagree on less extreme behaviors like sex-stereotyped jokes and repeated date requests. The study suggests that gender differences in perceptions of harassment may be influenced by socialization and value systems.
A study by Steven M. Ortiz finds that athlete wives develop coping strategies to deal with the stress of infidelity, often using humor or changing boundaries of trust. The wives who marry athletes for glamour and money may be more accepting of their husbands' affairs.
Researchers present promising treatments for renal cell carcinoma using 5-aminolevulinic acid fluorescence detection, as well as a vaginal mucosal vaccine for recurrent urinary tract infections. Additionally, studies investigate the long-term health-related quality of life impacts of different prostate cancer therapies.
Researchers found that intelligent adolescents tend to postpone any kind of lesser sexual activity, as well as first sex, compared to their less intelligent peers. The association between intelligence and refraining from sexual intercourse was stronger for girls than boys, and age-dependent.
Researchers identified five brain areas activated during sexual arousal, including the inferior temporal cortex and right orbitofrontal cortex. The study used positron emission tomography to map brain activity while subjects watched different films, providing insights into the neurophysiological bases of human sexuality.
A study on non-Western folk beliefs found that partible paternity is a common concept among indigenous groups in South America and New Guinea. This ancient tradition suggests that every man who contributes sperm during pregnancy biologically contributes to the child, challenging the long-held assumption of a single biological father.
Researchers studied 1,200 female crack users, finding that exchangers were four times more likely to have been in substance abuse treatment and twice as likely to be homeless. The study aims to develop effective HIV prevention measures targeting women at risk of exchanging sex for drugs.
A landmark study found that behavioral interventions can cut high-risk sexual behaviors in half and more than double regular condom use among hardest-to-reach populations. The intervention, which focuses on motivation and skills to reduce high-risk behaviors, was effective in reducing gonorrhea incidence by half among men.
Diane Morrison, a University of Washington research associate professor, argues that parents need to teach their children about safe sexual behavior. She believes that if Americans want their kids to learn positive sexual values, parents should have open and honest conversations about sex, condoms, and birth control.
A San Francisco State University study found that women taking triphasic Orthonovum 7/7/7 pills experience higher levels of sexual interest and satisfaction compared to those using monophasic pills or no birth control. The study suggests a physiological basis for the difference, contradicting earlier predictions.
