While that's true, a newly married couple TTC a baby? Assuming they are having sex on a fairly regular basis? The incidental microtrauma to the vagina would make it highly unlikely that she would not have contracted it.

Assuming of course that she doesn't have some sort of genetic anomaly that would give her some sort of super resistance. Apparently was interesting enough for some people to think twice.

There are plausible explanations for everything that I tend to believe but it is an interesting theory.
