Susan, I have been listening to audio tapes. The doctors speaking on these seminar tapes have written books on the subject of hormones and the Estrogen/Progesterone balance.

I have not read these books yet. They may provide the information you seek. Natural Progesterone By Dr. John Lee What Your Doctor May Not Tell You About Your Hormones By Dr. John Lee Health In The 21st Century, Will Doctors survive? By Francisco Contreras (Spelling?)
