Dylon, I'll try to answer your questions. :) The problem with HPV is that there aren't a lot of absolutes, but I'll try. (And anyone feel free to contradict! sdp, I'm looking in your well-read direction! :))

How often does HPV lead to cervical dysplasia (that's cancer of the cervix right?) in women? First off, neither displasia or HPV are the same as cervical cancer. However, according to just about everything I've read so far about HPV, the reason they worry so much about cervical displasia/abnormal HPV related cell changes on the cervix is because 98% of women who are diagnosed with cervical cancer have HPV cells in there too. But as usual, nothing is absolute. That could mean absolutely nothing, although the common belief in the medical community is that untreated cervical HPV = cervical cancer.

Are condoms effective in preventing HPV from being transmitted to the cervix even if it it transmitted from the male to the female from skin outside the condom? Supposedly condoms can help prevent the transmission of HPV to the cervix. That's the good news. The bad news is: if you are a carrier of HPV (as a male or female) and you've been handling yourself and vaginally penetrate your partner with your hand/tongue so on, it can be transmitted. Whether or not it makes it up to the cervix is a crapshoot. But HPV/genital warts are extremely contagious, just like herpes (and a number of other STD's).

Or is it the case that once a female is infected anywhere with HPV she runs a higher risk of cervical cancer? This one I can't answer. I don't think external warts raise your chances of cervical cancer, and because doctors can't really PROVE that HPV leads directly to cervical cancer it may not even matter. I suppose in the end it's all about your paranoia and your vigilance about keeping your body healthy, really. From what I have read, it sounds like HPV leads to a more benign cyst like cancer that presents itself in tumor form, however the scarier cancers HPV can cause are head and neck cancer. Weird huh? So who knows.

What percentage of females with HPV get cervical dysplasia? I can't answer this one either. Because HPV can be present without displasia and vice versa, there are no real numbers. Same with HPV or displasia leading to cancer, although the hindsight numbers (as I mentioned above) are 98%. But that isn't particularly helpful, because it doesn't say how many women without cancer had displasia or HPV.

Does HPV pose any risks to men outside of having warts that must be removed? This one is pretty important. HPV in men (even with no visible warts or symptoms) if left long enough can supposedly lead to penile and possibly testicular cancer. (See above on 'supposedly' about the leading to cancer and being vigilant! :)) I still haven't found any accurate reading material on that though...just kind of vague threats of "if you don't treat it, it may lead to" and that kind of thing. Although men can be tested for outward signs of HPV even if they don't see visible warts, the testing process isn't all that accurate. It's the same test as the one they do for women, but they treat the entire length of the penis with the vinegar solution to see if there is any reaction from the damaged cells. Does it work in all cases? Nope. But it is a good piece of mind test if you are afraid you are a carrier.

I don't know if ANY of that helps, and frankly any of it can be rendered moot because there are so many varying reports about what HPV is/how it presents itself/if it's cancerous/how it's transmitted. Each report I've read has different information. Mostly I think the medical community is stumped about it.
