About
Dr. Paul Turek is a board-certified urologist and fellowship-trained master microsurgeon who focuses exclusively on male fertility and sexual health. He spent the first 15 years of his career as an academic surgeon at one of the country's leading medical institutions, advancing the field of men's reproductive health through research and clinical innovation. His career spans more than 25 years, during which he has performed over 2,500 no-scalpel vasectomies and published extensively on vasectomy reversal, sperm mapping, and male infertility.
Dr. Turek invented Sperm Mapping, a proprietary FNA-based technique that locates sperm in men with non-obstructive azoospermia without open surgery. He created the Brosectomy concept and introduced nitrous oxide as a comfort option for vasectomy patients. He collaborated with Dr. Mark Solomon to develop testicular enhancement via fat transfer, becoming among the first physicians to offer the procedure. He has lectured internationally, including at the leading Japanese male fertility society in Kobe, and collaborated with Dr. John Amory at the University of Washington School of Medicine on retinoic acid research for azoospermia. Healthline has named his men's health blog one of its top blogs every year since 2016. He co-founded Clinic by the Bay, a free clinic for the working uninsured in San Francisco. Outside medicine, he is passionate about cycling and has a daughter who inspires much of his thinking about fatherhood and family.
