Almost half of college students judge men and women with similar sexual histories by the same standard and hold equally negative attitudes towards both their male and female peers who they believe hook up "too much," suggests new research to be presented at the 107th Annual Meeting of the American Sociological Association. http://phys.org/news264352285.html Other Sciences Fri, 17 Aug 2012 00:00:01 EST news264352285 (Phys.org) -- The propagation of every animal on the planet is the result of sexual activity between males and females of a given species. But how did things get this way? Why two sexes instead of one? Why are sperm necessary for reproduction and how did they evolve?  http://phys.org/news263710809.html Biology Thu, 09 Aug 2012 06:00:37 EST news263710809 Policymakers struggling to stop the spread of HIV grapple with "what if" questions on the scale of millions of people and decades of time. They need a way to predict the impact of many potential interventions, alone or in combination. In two papers to be presented at the 2012 International AIDS Society Conference in Washington, D.C., Brandon Marshall, assistant professor of epidemiology at Brown University, will unveil a computer program calibrated to model accurately the spread of HIV in New York City over a decade and to make specific predictions about the future of the epidemic under various intervention scenarios. http://phys.org/news262619507.html Technology Fri, 27 Jul 2012 14:51:54 EST news262619507 In Sub-Saharan Africa, women who are empowered to make household decisions tend to have sex less often. This is according to a study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. They examined the relationships between married women's autonomy and the time since most recent sexual intercourse and found that women's position in their household may influence sexual activity.

Men in good or excellent health at 55 can add 5 to 7 years to that number. Equally healthy women gain slightly less, 3 to 6 years. http://phys.org/news187386578.html Medicine & Health Tue, 09 Mar 2010 19:49:53 EST news187386578 According to the Journal of Sexual Medicine, people who engage in regular sexual activity gain several health benefits, such as longer lives, healthier hearts, lower blood pressure, and lower risk of breast cancer. However, approximately 33 percent of women may not receive these benefits due to low sexual desire. Also, the marriages of women with low sexual desire may also be at risk, given a recent statistic that 25 percent of divorce is due to sexual dissatisfaction. http://phys.org/news187357367.html Medicine & Health Tue, 09 Mar 2010 12:00:01 EST news187357367 A new study weighs in on the controversy over sex education, finding that an abstinence-only intervention for pre-teens was more successful in delaying the onset of sexual activity than a health-promotion control intervention. After two years, one-third of the abstinence-only group reported having sex, compared to one-half of the control group. The study by researchers at the University of Pennsylvania appears in the February 1 edition of the Archives of Pediatrics & Adolescent Medicine. http://phys.org/news184269459.html Medicine & Health Mon, 01 Feb 2010 18:40:01 EST news184269459 (PhysOrg.com) -- Ever since the dawn of time, teenage boys have been defined by their sexual urges. Stereotype or not, the same fate has now befallen male mice.

Continued marijuana use may result in a number of serious consequences including depression, cognitive impairment, cardiovascular disease, and certain forms of cancer. As such, it is critical to prevent marijuana use by adolescents and numerous behavioral and medical scientists have been trying to establish the best means of prevention. http://phys.org/news177603743.html Medicine & Health Mon, 16 Nov 2009 14:40:05 EST news177603743 A study at Johns Hopkins Children's Center found that girls diagnosed with pelvic inflammatory disease (PID) who watched a short educational video were three times more likely to discuss their condition with their partners and to ensure partner treatment than girls diagnosed and treated without seeing the film. http://phys.org/news176636714.html Medicine & Health Thu, 05 Nov 2009 09:45:34 EST news176636714 Alcohol and drug use are known contributors to adolescents engaging in dangerous sexual activity; leading to substantial health risks such as unwanted pregnancies, sexually transmitted illnesses, drug overdoses and alcohol poisonings. Yet, research suggests that fewer than half of pediatricians report screening patients for substance use and at-risk sexual behavior. CRAFFT, the diagnostic test developed and currently being employed at Children's Hospital Boston, allows primary care physicians to accurately screen teens for high risk drug and alcohol use in a matter of minutes. Now, according to a new study appearing in the Journal of Adolescent Health, Children's researchers have established that the CRAFFT diagnostic test can also identify teens that are more likely to be engaging in high risk sexual behaviors. http://phys.org/news174918575.html Medicine & Health Fri, 16 Oct 2009 14:00:01 EST news174918575
