But there is no indication that the patient in question actually had a problem requiring medical attention.
If this person has had a vaginoplasty and was experiencing a medical problem, they should contact the hospital department responsible for their ongoing care. (There will be one. Surgeons don't perform complex surgeries such as this with high complication rates and then just release you into the wild.)
It is not even clear from the article whether this person has had a vaginoplasty or whether they are actually just a bog standard male bodied person with male genitalia.
Reading between the lines it sounds very much as though this person just made an appointment to see a gynaecologist because that's what women do once a year.
But the gynaecologist doesn't treat male patients, hadn't consented to seeing a penis, and should in no way be obliged to pretend that this person wasn't wasting his time or pander to their feelings.
If the patient was genuine, then once the doctor had sent a message via the receptionist offering to direct them to a more appropriate doctor, they would have taken that information, thanked the receptionist and left quietly, probably feeling deeply embarrassed about the whole thing. That would be the normal reaction of someone who only has a very vague understanding of what a gynaecologist does and why women go to see one once a year, and made an innocent mistake.
But the scene that ensued in the doctor's waiting area, plus the subsequent Google review and the involvement of various trans lobby groups calling this poor doctor homophobic and transphobic is really all the evidence we need that this isn't about trans people being unable to access appropriate healthcare, it's about trans activists deliberately stirring up trouble. They really need to get some sort of hobby instead.
