Besides reproductive choices, what other medical decisions are women incapable of making all by ourselves...?

Depends on where you go. Go to Sweden and you can probably do all sorts of things by yourself. Plenty of rights. For now. Go to Iran, you probably can't decide for yourself how long to let your pubic hair grow. Go to America, you have some choices, you lose others. I don't like it but I still prefer it to living in Iran and for that matter to living in most countries.
