Can a woman who has undergone treatment become infected again by the same man?

Re-infection by the same sexual partner is not an issue. If a woman was infected with one or more types of HPV by a man, the infection will develop into an inflammation or be suppressed, depending on the capabilities of her immune system. The final outcome (suppression or persistent lesions and in rare cases carcinogenesis) depends on her immune system and its tumour-suppressing mechanisms on the one hand and the type of the virus on the other. Many experts agree on the use of a condom for a few months after treatment even in monogamous couples, based on the concept of decreasing the viral load.

We always try to boost the immune system as well (stop smoking, avoid stress, get proper nutrition, adequate sleep, etc).
