When it involves the actions of the partner it's reasonable to require the partner to be part of it.
Really? Medical personnel are not allowed to inform intimate partners of those who are being treated for STIs that they have been exposed, including if the intimate partner is a pregnant woman, meaning not only is her health at risk but so is the child’s.
Men are not required to bring their intimate partners if they want a vasectomy or ED medication.
I agree that it is the absolute duty of the physician to ensure that the patient is aware of medical consequences if a pregnancy occurs. I even think the doctor had a duty to ask if the patient thought it would be helpful for the partner to join in discussions so that they are also aware of adverse consequences of a pregnancy while she is being treated fir cluster headaches.
But the doctor has no right to do more than offer or to ask if the patient needs further support or guidance.
