I'm a Professor Studd patient and his prescription worked well for me except I had the usual problems with Utrogestan because I am intolerant to all types of progesterone used in HRT preparations. I do really like Oestrogel and didn't know about it until I went to him.
Why not ring his office, speak to his secretary and ask a few questions? That way, you might be able to gauge whether or not he will be able to help you before deciding on an appointment. He can do telephone consultations if that helps.
Anyone can prescribe his preferred Oestrogel/Utrogestan/testosterone regime but it is the low dose progesterone that is the real game changer. The NHS always prescribe a higher dose of progesterone which doesn't work for many women, myself included.
