I'd rather have a guide than a gatekeeper. I feel like gate keeping is unethical to a certain extent: the medical professional has the ability to ease the mental and emotional suffering of an individual, but won't until certain arbitrary criteria are met. If I had a malignant tumor, I would sign a paper and have it removed. If my testes are secreting a hormone that has effects which cause me mental and emotional distress, I should be able to sign a paper and have them removed(after appropriate education is given to the individual). I'm an advocate of informed consent, but completely understand why some medical professionals wouldn't put themselves out there in such a fashion and favor what is commonly referred to as "gatekeeping."
