The comment "thanks for spreading the knowledge!" Made me cackle. I mean it's cool but humans aren't fish. They have nothing to do with each other regarding reproduction. Here's a post on why my #2 ✏️ and an 🍊 on my desk are related because wood comes from a plant and a plant is how oranges grow.
oh, to fill the comments with false analogies.
Human beings are not fish, and we do not change sex.
Show me one, one! example of sex change that is inclusive: chromosomes, gametes, organs, hormones, primary and secondary sex characteristics.
Fish might be more evolved, we are not.
