Fruit flies, like many animals, engage in a variety of courtship and fighting behaviors. Now, Salk scientists have uncovered the molecular mechanisms by which two sex-determining genes affect fruit fly behavior. The male flies' courtship and aggression behaviors, they showed, are mediated by two distinct genetic programs. The findings demonstrate the complexity of the link between sex and behavior.
Randomized Control Trial under an NIH grant demonstrates the efficacy of a clinic-based triadic healthcare intervention called 'Families Talking Together' to protect adolescents from sexual health risks such as unwanted pregnancy and HIV/AIDS.
COVID-19 is unlikely to be spread through semen, according to University of Utah Health scientists who participated in an international study of Chinese men who recently had the disease. The researchers found no evidence of the virus that causes COVID-19 in the semen or testes of the men. The study could not fully rule out the possibility that the disease could be sexually transmitted. However, the chances of it occurring appear to be remote.
Researchers from Michigan State University released a study on 'sextortion' -- a lesser-known internet crime that poses a threat to adults and minors -- that sheds light on the importance of protecting the public from online criminals.
A recent study found that LGBTQ service members face an elevated risk of sexual victimization including harassment, assault and stalking while in the military than their non-LGBTQ counterparts.
Gender-based violence has been shown to increase during global emergencies. In a paper just published by Columbia University Mailman School of Public Health, researchers report that according to early evidence it is the same for the COVID-19 pandemic.
This study combined the results of 29 studies with nearly 12,000 black adolescents to examine the association between attending sexual health programs and outcomes such as sexual behavior (condom use, number of partners) or abstinence, contraction of sexually transmitted infections and pregnancy.
Sexual health interventions are effective at increasing both abstinence and condom use in black adolescents, according to research evaluating dozens of studies on interventions and outcomes in black youth.
Three chemicals with floral, fruity scents are likely essential ingredients in the natural cologne male ring-tailed lemurs use to attract a mate. Experts in odor communication say these chemicals could be the first fully identified sex pheromones in primates.
UK researchers reported that men in Uganda and Nicaragua were generally less hung up about their body image and cared less about pursuing a muscular physique than British men. The study employed new body-imaging technology and machine learning to understand different cultural attitudes around the drive toward ideals of muscularity. Understanding variation between groups is important to ensure any strategies or interventions addressing negative behaviors are tailored to a specific cultural context.
