The study found that only 40 percent of those surveyed routinely ask questions to assess for sexual problems or dysfunction. Far fewer, 29 percent, routinely ask patients about satisfaction with their sexual lives and 28 percent routinely confirm a patient's sexual orientation.

They discovered that homosexual men reported that their sexual performance and satisfaction more than halved in four of the six categories studied. Heterosexual men, on the other hand, reported fewer problems and were considerably more satisfied with intercourse.

Urologists compared 11 evidence-based studies covering 230 men between 2000 and 2009. They found that surgical techniques resulted in average flaccid size increases of between 1.3 cm and 2.5 cm and three types of penile extenders resulted in average flaccid increases of 0.5 cm to 2.3 cm.

However, this minimally invasive treatment -- prostatic artery embolization -- has none of the risks associated with TURP, such as sexual dysfunction, urinary incontinence, blood loss and retrograde ejaculation, say researchers.

But men undergoing the procedure did not enjoy the same significant urinary function improvements as the women. They also reported that erectile function was slightly worse after surgery, unlike studies following non-surgical weight loss where sexual function actually improved.

However, the evening may not turn out as planned, according to a new study, which evaluated the effect of a wide range of drugs, including alcohol, on sexual behavior.

This is the most complete replacement of penile erectile tissue to date and suggests the possibility of using the same approach for men with erectile dysfunction or conditions that require reconstruction, including penile cancer and congenital abnormalities.

More than half the internists responding to a survey indicated they rarely or never discussed sexual problems with their patients who had survived cancer.

ACP strongly recommends that physicians initiate therapy with an oral phosphodiesterase type 5 (PDE-5) inhibitor in men who seek treatment for ED unless they have a contraindication to PDE-5 inhibitors, such as nitrate therapy. As for which PDE-5 inhibitor to use, ACP recommends that physicians base the choice on the individual preferences of patients including ease of use, cost of medication, and adverse effects profile.

The study also uncovered a positive association between age and well-being, but a negative association for general health.
