Clinical Associate Professor Darren Katz is an internationally recognised urological surgeon and the Medical Director of Men’s Health Melbourne, with particular expertise in male infertility, microsurgery, erectile dysfunction, penile prosthetic surgery and men’s health.

A/Prof Katz is a Clinical Associate Professor in the Department of Surgery at the University of Melbourne and the immediate past Leader of the Andrology Special Advisory Group of the Urological Society of Australia and New Zealand (USANZ). He also sits on an expert advisory panel for the Australian Government Department of Health.

International training and surgical expertise

A/Prof Katz graduated from the University of Melbourne Medical School in 2001 and subsequently completed specialist urological training through the Royal Australasian College of Surgeons.

He then spent two years in New York undertaking advanced subspecialty fellowships at two of the world’s leading medical institutions — Memorial Sloan Kettering Cancer Center and Weill Cornell Medical Center.

His fellowship training focused on andrology, male infertility and microsurgery, urological prosthetics, erectile dysfunction, male voiding dysfunction and urinary incontinence.

Today, A/Prof Katz has a major referral practice in complex male infertility, prosthetic urology and minimally invasive prostate surgery. He performs highly specialised procedures including microsurgical sperm retrieval (micro-TESE), microsurgical varicocele repair, vasectomy reversal and penile prosthesis surgery.

He also has extensive, high-volume experience in general urology including minimally invasive treatments for benign prostate enlargement (BPH), including Rezum water-vapour therapy, UroLift and iTind. These techniques can provide effective relief of urinary symptoms while avoiding or reducing many of the potential side effects associated with more invasive prostate surgery.

Teaching and international fellowship

During the fellowship, they receive intensive subspecialty training in the latest treatments and surgical techniques in male infertility, microsurgery, erectile dysfunction, penile prosthetics and other areas of advanced andrology and men’s health.

Through this fellowship, A/Prof Katz plays an important role in training the next generation of international subspecialist urologists and in sharing contemporary Australian surgical expertise internationally.
