Maintaining a good sexual health is one of the foremost concerns of individuals who actively participate in a sexual activity. However, a latest study suggests that men could face a bit more challenges when it comes to sexually-transmitted infections.


One of the greatest risk in terms of sexual health is developing throat and mouth cancer linked to oral sex. According to a research team at the John Hopkins University in Baltimore, Maryland, oral sex increases the risk of head, neck, throat and mouth cancer through human papillomavirus (HPV).








It is estimated that HPV affects nearly 70 to 80 percent of sexually active men and women and is one of the most common sexually transmitted infections. The researchers claim that men are twice likely to contract HPV-related cancers than women. The risk is particularly higher in middle-aged white men, as compared to men belonging to other races.


In case of men, the researchers found that the risk of oral HPV increases with the number of oral sex partners that men have had. However, the effect is opposite in the case of women. That is, the number of sexual partners does not seem to increase the risk of oral HPV in women. Women with greater number of vaginal sex partners had a lower risk of contracting HPV-related cancer as compared to men.


The researchers say that the difference lies in the robustness of the immune response in men and women. Men do not seem to have a robust immune system, however, women develop an immune response that prevents them against an oral HPV infection as soon as they encounter HPV vaginally, reports MedicalXpress.





According to researcher Gypsyamber D’Souza, two of three cases of oral cancer in the US can be can be attributed to the HPV 16 strain infection, reports The Tech Times.


The complete details of the study have been published in the Journal of the American Medical Association.

The Evolution Of Hairy Men: Why More Hair Attracts The Opposite Sex, Indicates Greater Health



Hairy chests

The guys of AsapSCIENCE get to the bottom of why some men are so hairy. torbakhopper, CC BY-ND 2.0





Everyone has hair, but why do men tend to have so much more of it? The guys of AsapSCIENCE recently looked to evolution for the answer.


“All humans have the same number of hair follicles as our primate ancestors, except our hair now is much more thin and unable to be seen by the human eye,”  the YouTube hosts explained on their second channel AsapTHOUGHT. “Throughout evolution it became an advantage to have thinner hair, and it’s thought to be this way because our ancestors were traveling far distances to find food and, in the heat, thick hair was a disadvantage.”


While men and women, too, have the same number of hair follicles, men have more of what’s called terminal hair: visible, thick hair that’s usually associated with the hair on a person’s head or pubic hair. Men have this hair “on their chest, back, and other places.” Women can also have hair in these places, but they have more vellus hair, which is hair that’s even thinner and harder to notice. Apparently, these differences have to do with sexual selection.


Male peacocks, for example, flash their tail feathers to display their fitness in order to attract potential mates. One theory even suggests hairy men are better able to detect parasites on their body, so females perceive more hair as a marker for greater, parasite-free health. It makes sense then biology professor Pavol Prokop has said hairless men are preferred more in areas closer to the equator, where there’s an increased number of parasites.So it may be men became hairier so it would be easier to attract potential partners.
