I've just read up on something called empty sella syndrome shown on brain MRI. The sella is normally filled by the pituitary gland. In this syndrome, the gland is flattened or filled with CSF. The most prominent symptoms are related to hormones. In your shoes, I would seek out a female doctor, preferably one over 50! It would be entirely normal to see a gynecologist for hot flashes and a female would not diminish your symptoms. You might also start adding more soy to your diet, such a tofu.
