Female sex hormones play a vital role in defense against sexually transmitted diseases
Two McMaster University studies, to be published in the Journal of Virology, show that sex hormones have a profound effect on susceptibility of female mice to the herpes simplex virus, type 2 (HSV-2 ), one of the most common sexually transmitted diseases. Charu Kaushic, assistant professor and supervisor of the studies, says the implication of this work is quite significant. "The research...Sexual cooperation: Mating increases longevity in ant queens
The phenomenon of sexual conflict is a powerful driving force in the evolution of reproductive biology for many animal species. Males often try to manipulate their female mates during copulation--for example, by traumatic inseminations (as in the case of bed bugs) or by the transfer of toxic seminal fluids (as in the case of the fruitfly Drosophila). These manipulations are beneficial to males be...New study: Sexually transmitted disease treatment can be effectively administered by sex partners
Effective control of sexually transmitted diseases (STDs) requires treatment of the sexual partners of infected patients.

Men with...High rates of sexually transmitted infections found in young drug users
Researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions found high rates of herpes simplex virus 2 and syphilis among young drug users in Baltimore, Md. The study found that women had significantly higher rates compared to their male counterparts, but did not find significant differences between injection drug users and non-injection drug users.

A male fly's sexual courtship of a female fly is a complicated business of tapping, singing, wing vibration, and licking, but a single gene is all that is needed to produce this complex behavior, according to new research published in this week's issue of the journal Cell. The gene encodes the Fruitless protein. Male and female flies carry different versions of the fruitless protein, as a...Sexual abuse affect health for a lifetime

Almost all women, as they go through menopause, will gradually develop changes in genital organs-particularl...Hypertensive Drug Improves Sexual Dysfunction in Hypertensive Men
Losartan, a new anti hypertensive drug appears to improve sexual function among the hypertensive men with erectile dysfunction. As the cause of impotence, really it is the disease process itself, probably from reduced vascular compliance. According to American Journal of Medical sciences, a study evaluated hypertensive men with erectile dysfunction and found that their overall sexual sat...New dimension in the treatment of female sexual dysfunction
Female sexual dysfunction is associated with loss of libido, low motivation and fatigue, most often occurring in women who have attained their menopause or whose ovaries had been removed surgically for some reason. Dehydroepiandosterone(DHEA), may serve as an effective treatment in such sexual dysfunction, according to a study released at the 96th annual meeting of the American Urologica...The phenomenon of sexual attraction
Romance has long been described as a process of bewitchment, but scientists have found that there may be more truth to this than meets the eye. They say female chemical messengers known as pheromones may help dupe men into thinking plain women are more attractive and beautiful women are less attractive than they actually are.// Pheromones - the colourless, odourless chemical signals g...Sexual orientation and medicine
