Thank you Dr. Hook.
That was a very complete answer.

Welcome to the Forum. I’ll try to help. At this time it will be difficult to tell if the lesion on your penis was a wart or not since it is gone and/or any remaining tissue has been altered by the liquid nitrogen therapy making it difficult to tell. It certainly sounds as though it could have been however.
Liquid therapy for warts needs to be continued (at intervals) until the wart is gone. Sometimes this can be accomplished by a single treatment and on other occasions, several treatments are needed. Many clinicians request that persons treated for warts return so that they can judge whether or not more treatment is needed. Even with apparent complete response, about 15-20% of warts do recur (in that same spot), doing so within 2-3 months of initial therapy.
The treatment and the presence of the wart, if that is what it was, will induce an immune response and should help to keep additional warts to recur however the effect of the immune response is not 100%
Untreated, nearly all warts "clear" within 18 months of infection. Clearance, whether due to the treatment you received or if accomplished by the action of your immune system will mean that you are no longer infectious for sexual partners. Typically we suggest that persons use a 3-month period after treatment to make sure that warts will not recur before they assume that they are not infectious for sex partners.
I hope that I have addressed your questions satisfactorily. The topic of HPV and genital warts is a complex one. For additional information on this most common of STDs, I would suggest search for other HPV- and wart-related Q&A on this site, as well seeking addition information on sites such as the American Social health Association web-site (disclosure, Dr. Handsfield and I are both on the Board of ASHA).
