To me "Informed Consent" leaves a gatekeeping psyc eval out of the equation. It is simply the MD "Informing" you of all the effects of HRT, both physically and perhaps psycho-social things like "How will your spouse feel" or "How would work be if you had a pair of bouncy girls?". As with any medical treatment side effects are a given, even if they may be desired. And of course, any CYA medical/physiological testing like a blood workup, family history etc..
Now, in this litigious day and age I can see docs wanting, better yet needing, a CYA letter, just in case. This I can understand the medical community saying/recommending a CYA letter. At the very least to make doctors think before simply prescribing HRT.
At the end of the day just why should HRT be any different from any other not really medically necessary drugs like ED medications, hair loss, botox injections? Same goes for the disparity for what would otherwise be typical cosmetic surgeries.
