Dr Hertoghe is the European hormone expert. I saw his group last week and have to say that I am quite pleased with the results of their findings and the treatments they prescribed for me to take. I had been suffering from many strange things for quite some time. They take you seriously and don’t tell you it’s all in your head. Dr. Hertoghe has written numerous books about hormones as well. They are private doctors though so get ready for the price! This review was written in 2009.
