Funnily, my alternative comes from the same "authority" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9341318/ though to be specific it does not in any way disagree with your citation, as yours deals with sexual organs. The NIH is clear that "Sex" and "Gender" are two different things.

Though my actual alternative is: Why should I care about specific definitions of "Man" and "woman"? I prefer duck typing for human stuff, because we are messy and every "line" is more like a fuzzy spectrum, and each and every time we have tried to place an arbitrary line, it's been wrong. I'm especially keen to this as a programmer, who is well aware that things people tend to think are "clear", like names, gender, time, etc, rarely are.

I'm unclear as to what your alternative actually is. Your claim seems to be that the concepts of "woman" and "man" are too difficult to define, but then, what next? Please could you elaborate on your view.
