Thanks! I'm on the biology side of things, so I tend to avoid going into gender because I don't understand it as well, but the biology seems clear enough. The gender side also makes sense to me broadly, since we have complex and varied cultures, and having a term to talk about different societies also seems helpful. There are multiple languages and cultures with explicit terms for intersex, for example.

I'm not super clear on why gamete size has become a popular argument for a so-called binary model, since intersex still exists and there are individuals with both gametes. Not to mention, for sports, gamete size seems much less relevant than hormones and natural variation within each sex/gender, and that seems to be the favorite example. Do you have any insights as to why gametes have become a popular argument?
