Can aspects of personality help explain a predilection towards risky sexual behaviors in developing adolescents? Researchers approached this question by surveying middle adolescents of various personality types. The three most common personality types found across cultures and age groups are undercontrollers (extroverted, disagreeable, unconscientiousness, open to new experiences), overcontrollers...
Decreasing HIV transmission among Russian HIV-infected drinkers will require creative and innovative approaches, results of a new study conducted in St. Petersburg, Russia, show. While new HIV infections globally have declined, HIV rates remain high in Russia. This is due in large part to injection drug use and spread via heterosexual sex transmission. ...
Sexually transmitted infections can make HIV transmission more likely, undermining the prevention benefit of HIV treatment. A new study of HIV-positive patients in Cape Town, South Africa, found that the prevalence of such co-infections was much higher before beginning HIV treatment. Testing for and treating STIs and HIV together could therefore improve HIV prevention. ...
Concerns about guardianship and privacy can discourage clinics from testing children for HIV, according to new research from Zimbabwe. The results of the study provide much-needed information on how to improve care of this vulnerable population. ...

There are many misconceptions and unknowns about premature ejaculation in the medical community and the general population. Two new papers provide much-needed answers that could lead to improved diagnosis and treatment for affected men. Premature ejaculation can cause significant personal and interpersonal distress to a man and his partner. While it has been recognized as a syndrome for well over 100...
One in five adult women and one in 100 adult men have reported being raped. The prevalence increases to two in five among women and one in five among men who report experiencing other forms of sexual violence, such as repeated unwanted sexual contact and sexual coercion. Now, researchers have determined that those victims who are repeatedly assaulted, show greater levels of psycho-behavioral consequences...
The way in which the sex of an organism is determined may require lifelong maintenance, finds new research. Sex-specific transcription factors perform lifelong work to maintain sexual determination and protect against reprogramming of cells from one sex to the other. Using a mouse model, researchers found the sex of gonadal cells -- those found in the ovaries or testes -- require maintenance throughout...
There are many misconceptions and unknowns about premature ejaculation in the medical community and the general population. Two papers, both being published simultaneously in Sexual Medicine and the Journal of Sexual Medicine, provide much-needed answers that could lead to improved diagnosis and treatment for affected men. Premature ejaculation can cause significant personal and interpersonal distress...
Birth control is used worldwide by more than 60 million women. Since its introduction, it has changed certain aspects of women's lives including family roles, gender roles and social life. New research also found a link between birth control and women's preferences for psychophysical traits in a sexual mate. ...
Women's sexual satisfaction in long-term heterosexual relationships may be influenced by changes in hormonal contraceptive use, research shows. "Our findings showed women who had met their partner while taking the pill and were still currently taking it -- as well as those who had never used the pill at any point -- reported greater sexual satisfaction than those women who had begun or stopped using...
Join Lisa Ling as she recounts poignant moments while filming Season 2 of Our America. From witnessing the cycle of crime and punishment to being faced with the horrors of sex trafficking, Lisa discusses the people and stories that affected her most....
Higher rates of binge drinking by lesbian and gay adolescents compared to their heterosexual peers may be due to chronic stress caused by difficult social situations, according to a new study. ...
New techniques for identifying body fluids -- especially important in cases of alleged sexual assault -- have been pioneered by a PhD candiate, who has focused her studies on the topic. "If a male doesn't produce sperm, he doesn't produce DNA, so I am trying to differentiate between seminal fluid and semen so that I can strongly support the hypothesis that sexual intercourse did occur even if the DNA...
The human body produces chemical cues that communicate gender to members of the opposite sex, according to new research. Whiffs of the active steroid ingredients (androstadienone in males and estratetraenol in females) influence our perceptions of movement as being either more masculine or more feminine. The effect, which occurs completely without awareness, depends on both our biological sex and our...
Partners of patients diagnosed with human papilloma virus (HPV)-positive oropharyngeal cancer (OPC) were no more likely to test positive for oral HPV infection than people in the general population, according to a study. The findings should lessen anxiety that OPC cancer is contagious, at least among long-term partners, and confirms that couples who have been together for several years do not need...
Joseph is nervous about getting tested for sexually transmitted diseases, since he hasn't always used protection. Marcus thinks he should come clean about how many women he's slept with if he wants a fresh start with Leslie....
Even though LGBT populations are often grouped together, each is a distinct group with specific health care needs, authors of a new study say. This is especially true with older LGBT persons and involves issues ranging from housing and long-term care placement to home-health and the selection of health promotion practices. More than 2 million older adults identify as lesbian, gay, bisexual or transgender,...
Researchers at the University of Exeter have found that sexual conflict over mating impacts the parental care behaviour and reproductive productivity of burying beetles. These beetles have surprisingly complex parental care, similar in form to that provided by birds such as robins or blackbirds, with offspring begging to be fed by touching parents, who respond by regurgitating partially digested food....
In a new study that traces the evolution of HIV in North America, researchers have found evidence that the virus is slowly adapting over time to its human hosts. However, this change is so gradual that it is unlikely to have an impact on vaccine design. ...
