Don't expect your garden variety endocrinologists to be helpful when having sex hormone issues, typically they only care about "normal ranges". Doctors are taught to treat the reference ranges and ignore the patients symptoms and that's exactly what your friends doctor is doing.
Almost none of the doctors inside mainstream medicine are knowledgeable enough to treat sex hormone deficiencies which has largely been ignored for decades, so any doctor inside an insurance network will be useless and your friend must go private.
Birth control is poison!
