I’ll tell you the real reason. If anything happens to you during the procedure (which is very unlikely but possible) and your family decides to file a case, then the doctor will have to run behind the case for many years even though the law states that only your consent is required. Medicolegal cases take a lifetime.
You have to find another hospital and doctor who is willing to do the procedure.
Even if you file a case, doctor/hospital has the right to reject a patient when it’s not an emergency. So you’ll waste the time fighting for it.
If someone is not willing to do a surgery, it’s better to avoid them than force them to do it.
Just let it go and find another doctor.
