Adult men born with a severe urological anomaly in which the bladder forms outside of the abdomen report much more robust sexual lives than women born with the same condition, according to a small study led by urologists at the Johns Hopkins Children’s Center.

The convenor of a major sexual health conference under way in Queensland says Australia's rate of HIV infection is slowly getting worse.

Teaching adolescents to use condoms when abstinence fails is a reasonable strategy for preventing HIV, according to a new research study in PLoS Medicine.

Differences in sexual behaviours do not fully explain why the US HIV epidemic affects gay men so much more than straight men and women, claims research published ahead of print in the journal Sexually Transmitted Infections.

HIV infection is on the rise among young men who have sex with men (MSM) in New York City, according to preliminary data from the Health Department.

More than two thirds (69%) of sexually active New York City teens use condoms, compared to 63% nationwide, according to a new survey of public high school students.

The first nationally representative survey on the prevalence of sexual activity among older Americans provides a portrait of the intimate lives of people ages 57 to 85.

The first comprehensive national survey of sexual attitudes, behaviors and problems among older adults in the United States has found that most people ages 57 to 85 think of sexuality as an important part of life and that the frequency of sexual activity, for those who are active, declines only slightly from the 50s to the early 70s.

Novel research published in the current issue of The Journal of Sexual Medicine supports the claim that women with hypoactive sexual desire disorder or HSDD (persistent or recurrent deficiency and/or absence of sexual fanatasies/thoughts, and/or desire for, or receptivity to, sexual activity, which causes personal distress) show noted improvement in sexual desire and sexual function following low dose testosterone treatment.

The first study to look at sexual function in very long-term female survivors of genital-tract cancer found that these women were pleased with the quality of their cancer care but less satisfied with the emotional support and information they received about dealing with the effects of the disease and treatment on sexuality.

According to a new study published in The Journal of Sexual Medicine, sexual sensation in circumcised and uncircumcised men may not be so different after all.

Three clinical trials in Africa found that adult male circumcision reduced the risk of men acquiring HIV infection from heterosexual sex by 51-60%. While adult male circumcision may also have a role to play in preventing HIV transmission in the US, say scientists at the US Centers for Disease Control (CDC) in a paper in PLoS Medicine, "the extent of this role on a population basis is unknown."
