Homosexual men more likely to have erectile dysfunction
Homosexual men are more likely to suffer from erectile dysfunction (ED) than their heterosexual counterparts, according to a recent meta-analysis. On the other hand, the opposite is true for premature ejaculation (PE).
Researchers conducted a review of the databases of Medline, Web of Science, CINAHL and Scopus, selecting case-control studies that compared ED and PE prevalence rates between homosexual and heterosexual men. The Newcastle-Ottawa Scale was used to evaluate the methodological quality of the included studies.
A total of four studies were eligible for analysis, resulting in a pooled sample of 1,807 homosexual men and 4,055 heterosexual men. All included studies were of high quality, though selection bias could not be ruled out due to problematic recruitment procedures (through the internet or phone interviews).
Pooled analysis showed that homosexual men were at a significantly higher risk of ED compared with heterosexual men (odds ratio [OR], 1.49; 95 percent CI, 1.03–2.16; p=0.04). In contrast, the former were 28-percent less likely to have PE (OR, 0.72; 0.52–1.00; p=0.05).
Heterogeneity of evidence was significant in both cases (pheterogeneity=0.03 for both ED and PE), though determination of the source was impossible due to the small number of studies.
“These findings can drive future studies on sexual needs and concerns of homosexual men, which might not exactly match those of heterosexual individuals,” said researchers.
“However, the results should be interpreted with caution, because their generalization could be hindered by the nonprobabilistic nature of the samples, and a measurement bias could result from the use of different nonstandardized indicators of sexual dysfunctions,” they added.
