There's nothing wrong in knowledge or knowing it.

Seems like a reasonable question to me. We often hear about gender reassignment surgery, but not much is said about the specifics of it. So many people may not know whether a uterus is transplanted. If you don't know something, you might as well ask.

@Palacinky That's true, one could Google it. But that would be a technique that comes with no human interaction whatsoever, whereas asking in a setting such as this at least provides actual human interaction. And I am not sure that your comparison is entirely accurate. In this case, the question is purely about biology, whereas the "what is it like to be black?" question relates to subjective experiences rather than physical characteristics.
