US researchers have published the first large population-based study of nationwide trends in erectile dysfunction and its surgical management from 2001 to 2010. Using data from Medicare beneficiaries, the investigators found that while the prevalence of erectile dysfunction increased by 165%, the use of penile prostheses decreased by 50%, from 4.6% in 2001 to 2.3% in 2010. Prostheses have been increasingly used in sicker patients with significant comorbidities, however. Age, ethnicity, and geography often influenced whether patients would undergo penile prosthetic placement. “The research demonstrates the continued role for surgical treatment of erectile dysfunction that persists despite the increasing use of oral medications and that variation in this treatment exists even in the absence of clinical factors,” said Dr. Daniel Lee, lead author of The Journal of Sexual Medicine study.

Viagra and other related drugs are not a universal ‘cure-all’ for impotence, according to a new study from The University of Manchester and NatCen Social Research. Drugs, clinically known as oral phosphodiesterase type 5 inhibitors (PDE5i), have become the first-line medical treatment option for sufferers of erectile dysfunction (ED) – also known as impotence – since entering the UK market in 1998. An abundance of studies has demonstrated the effectiveness of such drugs. But researchers at The University of Manchester, who have studied the responses of more than 2,600 English men (aged 50-87 years), suggest that restoring ED pharmacologically is not a ‘cure-all’. Lead author of the study, Dr David Lee, found that older sufferers of ED who had used Viagra, or similar drugs such as Cialis and Levitra, still expressed concern or dissatisfaction with their sex lives. The paper, entitled “Erectile dysfunction and phosphodiesterase type 5 inhibitor use: associations with sexual activities, …

Using drugs for impotence does not increase the risk of malignant melanoma, researchers from Umeå University in Sweden conclude in a publication in JAMA, a top US medical journal. These results contradict previous research indicating such an association. Last year, a research team from Harvard University in Boston, United States, reported that Viagra, a phosphodiesterase inhibitor (PDEi) drug used against impotence, increased the risk of malignant melanoma of the skin. It was interpreted as if Viagra stimulated the growth of melanoma cells. Researchers from Umeå University, in collaboration with researchers in Uppsala, Lund and New York, now publish a study in JAMA (Journal of the American Medical Association) contradicting those findings. “Our research shows that already collecting one single prescription of a PDEi drug, such as Viagra, Cialis or Levitra, was linked with a statistically significant increased risk of melanoma; something that speaks against a biological connection,” …

Does a predilection for porn mean bad news in bed? That’s the conclusion of many clinicians and the upshot of anecdotal reports claiming a man’s habit of viewing sex films can lead to problems getting or sustaining an erection. But a new study from UCLA and Concordia University – the first to actually test the relationship between how much erotica men are watching and erectile function – shows that viewing sexual films is unlikely to cause erectile problems and may even help sexual arousal. The study, published in the online journal Sexual Medicine, was conducted by Nicole Prause, an associate research scientist in the Department of Psychiatry in the UCLA Semel Institute for Neuroscience and Human Behavior, and Jim Pfaus, a professor in Concordia’s Department of Psychology and Center for Studies in Behavioral Neurobiology. The science of sex Prause and Pfaus analyzed data, collected from 280 male volunteers during previous studies in Prause’s lab, for the effect watching erotica has o…
