Dr. Barrett Cowan, MD

Co-Founder and Chief Medical Officer 


Dr. Barrett Cowan is a Reproductive Urologist and has specialized in treating male patients with infertility for more than 20 years. He started using telehealth technology when the pandemic began and was pleasantly surprised to see patients were more relaxed and candid about their questions when speaking from the comfort and privacy of their own home, and with their partners by their side. The technology also made it easier for patients to schedule appointments from anywhere in the country. 

Seizing the opportunity to offer a better overall patient experience, Dr. Cowan, in partnership with his wife Pamela Pure, launched Posterity Health to make high-quality male fertility care accessible to all couples trying to conceive. 

Dr. Cowan completed his undergraduate education at Stanford University, graduating with distinction and with honors in biology. He obtained his MD with honors from Stanford University School of Medicine, where he additionally completed a special residency in urology and a fellowship in prostate medicine and ultrasound. Dr. Cowan is a board-certified Urologist through the American Board of Urology (ABU). 

Dr. Cowan takes great care with all of his patients and understands the most appropriate treatment methods for all kinds of urologic diseases and problems. He has particular expertise in microscopic and laser surgery and is committed to providing state-of-the-art care in a compassionate fashion.
