Our Doctors


Our consultant surgeons Urologists/Andrologists


Our doctors have played leading roles in the development, co-development or improvement of many of the modern surgical techniques currently standard throughout the world as well as pioneering holistic treatments of male sexual dysfunction and sub-fertility.

In addition to the individual medical excellence, what really differentiates us is the collaboration that IA promotes between our physicians. The surgical techniques and treatments that we offer are constantly improved based on the collective experiences of our doctors which is facilitated through continuous training and advanced data capture and analytical systems shared across all our practices. Difficult cases are reviewed collectively and we will always aim to arrange for our most specialist doctors to lead these.
