Board-Certified Urologist

Dr. Andrew Y. Sun is a fellowship-trained urologist specializing in men’s sexual, hormonal, and reproductive health. He brings extensive training in urology and andrology and is dedicated to helping men address sensitive health concerns with confidence and clarity.

Dr. Sun’s interest in medicine began early—he spent much of his childhood around hospitals where his parents were completing doctoral degrees in clinical pharmacology. After developing a strong interest in science and patient care, he pursued medicine with a focus on improving men’s health and quality of life.

Dr. Sun completed his medical degree at Harvard Medical School and his urology residency at the Cleveland Clinic. He then pursued advanced fellowship training in Male Reproductive Medicine and Surgery (Andrology) at UCLA Medical Center. His clinical focus includes erectile dysfunction, Peyronie’s disease, low testosterone, male infertility, and other conditions affecting men’s sexual health and overall well-being.

Outside of medicine, Dr. Sun enjoys traveling, alpine hiking, reading history, and Formula 1 racing. He lives in Dallas with his wife, Serena, and their corgi, Tiberius.
