I have never heard of circumcision to treat or prevent HPV or genital warts. Most likely your warts will stop recurring one of these days.
A comment about imiquimod (Aldara): Your wording implies you somehow have come to believe that imiquimod is the treatment of choice. You aren't alone; lots of MedHelp user seem to have that impression. Music to the manufacturer's ears, and a testament to their marketing strategy, but just plain wrong. Imiqimod is no more effective than any other wart treatment, either in terms of speed of response, completeness of response, or recurrence rate. Podophyllin, podofilox (Condylox), tri- or bichloroacetic acid, freezing, or laser cautery all work about equally (about 70% of the time) in the long run none is better than the others. If anything, imiquimod is less good than most (certainly less good than freezing or cautery) because it takes a lot longer and is expensive. If warts persist or recur with one method, you have to try something else.
Good luck-- HHH, MD
At this age? I'm a girl but I can imagine that being a big OUCH!!!!!!!
I don't know, but jeez, that sounds awfully excessive to me. Seems to me that would be like saying you keep getting athletes foot on your left foot, so you should just go ahead and amputate it so you don't have to treat it again.
Get crypotherapy (freezing). 90% or better chance that they will not return.
Aldara would not/and is not that effective. It is indeed a marketing tactic used by most dermatologists.
