BackTable Podcast

In this BackTable Urology podcast episode, Dr. Andrew Sun, director of the Center for Men’s Health at Urology Partners of North Texas, discusses the nuances of testosterone replacement therapy. He compares traditional exogenous treatments, like injections, with endogenous approaches that aim to stimulate the body’s own testosterone production. Dr. Sun highlights the benefits of newer oral testosterone formulations, such as KYZATREX™, which can preserve natural hormone production and are particularly beneficial for men concerned about fertility. The conversation delves into personalized treatment strategies, including combination therapies, to optimize hormonal balance and patient outcomes.

What Patients Are Saying

  • Anthony

    Dr. Sun is one of the few doctors who really listens to you and will always take the time to address your concerns and answer questions and is highly knowledgeable. Very highly recommended.

  • Jesus M

    Dr. Sun was recommended by a friend of mine, and I’m glad he was. He is not only obviously knowledgeable, he’s personable and as dedicated to providing the best experience as any man can hope. Himself and his Assistant, Deja, made me feel comfortable throughout the entire process. I recently contacted him about a specimen count as I was overseas and wasn’t available after the short healing time. An entire year since the procedure Dr. Sun is still as attentive to my needs as the day I met him. Thank you so much, Doc!

  • Guoliang Wang

    Dr. Sun was referred to me by my daughter who is a MD. I consulted Dr. Sun for my health remotely and was very impressed by his eagerness to treat patients and by his intelligence and deep domain knowledge in the field. He was very polite and asked detailed questions to really understand my situation. Then he explained to me patiently in full detail about the different medications, procedures/surgical options, and each of their advantages and side effects. I was so happy consulting with Dr. Sun as he helped me understand my health situation in a deeper and broader aspect. I highly recommend Dr. Sun.

  • Ty Turkett

    Never heard of Peyronie’s disease at 55 before speaking to Dr Sun but after him giving me an explanation and best direction for correction I felt much more comfortable moving forward with surgery. I am happy to say he did a fantastic job of correcting curvature and explaining after care stretching. I highly recommend Dr Andrew Sun as your urologist as he will continue to be mine moving forward.

    I was referred to Dr. Sun by a friend of mine, after reading his Bio I chose to have a consult with him. Dr. Sun is extremely intelligent and knowledgeable on many things when it comes down to male health. I chose Dr. Sun to do my NSV & was amazed by how little pain there was. I felt no pain during or after the procedure. Dr. Sun was gentle and accurate with every motion. He also possesses a very outgoing and comedic personality! Which made the entire procedure a breeze. Highly Recommend Dr. Sun!

  • Gehrig Saldana

    I gladly submit my personal referral for my excellent urologist, Andrew Y. Sun, MD. Dr. Sun has been my urologist for almost a year to date. I’m 71 years young, & noticed over the past few years I had to wake up too many times to use the restroom disrupting my sleep along with having ED creep up on me as I aged to my present age. My primary physician referred me to Dr. Sun & I’m glad he did! Dr. Sun’s care for my prostrate (multiple trips to restroom at night) issue & my ED issue are now resolved to a point where I sleep much better at night. Top that off with my ED issue now pretty much in my rear view mirror. In short, I feel like I’m living the life of a 50 year old dude! Thank you Dr. Sun! Gehrig Saldana
