I can't help suspecting it's the attitude of society about this, which is a shame. I know men who wish a male oral contraceptive existed for them to take to prevent pregnancy.
Appallingly, I have heard people say since HPV-caused abnormalities on the cervix are a bigger and more commong problem for women, having tests and vaccines is more important. Yet, who they think gives HPV to us?
In addition, penile, anal, and oral cancers are more rare, but they still happen to men.
However, I read what little documentation I could find about Centre National de la Recherche Scientifique's (CNRS) medication MVA E2. Not only has it proven successful in clinical trial with cervical dysplasia, but it has also proven successful in clearing up HPV-caused abnormalities on the penis.
There is also a blood test being developed, which is supposed to be more accurate than the PAP smear, and I'd like to know if it could detect abnormalities in men. Aside from that, if a test to detect cervical specific antigen can be developed, there is no excuse to not have a blood test to detect HPV.
