Post some examples of all these men's lives that have been ruined. Let's see whether these examples are, actually, worse than having been raped.

If you search online, you'd find that there are many, many cases where an Indian girl elopes/lives with a man on free will, has consensual sex but after a few days, months, or even years files a rape case for various obvious reasons, surprisingly often when forced by parents.
You wouldn't 'like' to believe, but Pune police once said 74% of rape cases reported to them were consentual sex later turned rape. In fact Mumbai police says the main reason of the low conviction rate is false rape cases.

And a lot, lot more, just help yourselves with some Googling.
I'm sorry for the state of affairs in the US about the claimed report ratio of the crime - however, a mere statement of anyone, by itself should never lead to an arrest, be it a man or a woman, because in a lot of cases there are ulterior motives in play.
