It seems remarkably patriarchal and patronising to decide women shouldn't have agency regarding their own bodies and in particular their reproductive system. I can see a surgeon wanting to be sure someone understands what they are asking for, and ensuring they know what the consequences will be but in the end that type of call should be left to a woman and not be imposed on them by society.

I'm going to take a different view. I appreciate your stance on this. But I think this gets a little bit more complicated.
First off, most of the arguments around reproductive autonomy for females is focused on access to safe legal abortions. And while abortions are still invasive procedures, they're not at all the same as tubal ligation or hysterectomy. They don't require any actual cutting of the skin or organs, nor do they generally include anesthesia. If they're early in the pregnancy, they don't even need sedation. Abortions also don't leave the female sterile and unable to conceive or carry a fetus (extremely rare exceptions, of course). So while it's not "reversible" for the specific fetus being terminated, it's not a life-long physical impact, and it has no permanent effects.
To the extent that tubal ligation and hysterectomy do require anesthesia and actual surgery, they should fall under somewhat different guidelines. There are considerably different risks, as well as impacts. I don't think that an adult female should be denied those procedures because "they might change their mind"... but there can certainly be clinical considerations that make it unwise, or introduce risks that surgeons are unwilling to take.
Those procedures should be subjected to the same clinical guidelines and considerations as any other surgery that is not directly life-saving. Knee and hip replacements, thumb surgery to remove arthritis, spinal fusion, etc. All of those should be subject to good medical guidelines... but "you might change your mind" isn't one of them.
The problem with current medical approaches for tubal ligation and hysterectomy is that there's a lot of emphasis put on "you might change your mind" even when the female in question has already had children, or has a well-established intent to not have children (like me at 35).
At the end of the day, when it comes to medical intervention, "Because I really, really want it and it will make me happy" isn't sufficient reason for a doctor to agree to a procedure. On the other hand "You might change your mind" shouldn't be sufficient reason to deny a procedure to a
well-informed adult either.
