In all honesty, the leading practitioners in this field are found in the United States. The Hertoghe Clinic in Brussels is certainly world-class and Dr. Robert Stevens, a member here at EM and the director of the Men's Clinic in Dorset, in the UK, is an exceptional practitioner. That said, the treatment protocols in the US are - far and away - the most sophisticated. I say that as a Canadian who has an exceptional doctor who freely admits to the sophisticated level of care available to men in the US.
