#260 ‒ Men’s Sexual Health: why it matters, what can go wrong, and how to fix it | Mohit Khera, M.D., M.B.A., M.P.H.

Mohit Khera is a world-renowned urologist with expertise in sexual medicine and testosterone therapy. In this episode, Mohit provides a comprehensive overview of male sexual health. He begins with an in-depth exploration of erectile dysfunction, shedding light on its prevalence across different age groups, diagnostic methods, and its intriguing connection to cardiovascular disease. He then ventures into Peyronie’s disease, penile fractures, penile enlargement treatments, prolonged erections, premature ejaculation, and anorgasmia. Shifting gears, Mohit delves into the intricate workings of testosterone, DHT, and estrogen, emphasizing their physiological significance and interplay. He explains blood tests for diagnosing low testosterone, the correlation between symptoms and blood levels in cases of low testosterone, and the pros and cons of different methodologies for increasing testosterone. He concludes with a thought-provoking conversation about the role of testosterone in patients with prostate cancer and addresses concerns surrounding DHT, finasteride, and post-finasteride syndrome.


We discuss:

  • Mohit’s career path and interest in sexual medicine and infertility [3:00];
  • The anatomy of the male genitalia [5:45];
  • The prevalence of sexual dysfunction, its impact on quality of life, and the importance of seeking help [7:15];

  • Priapism (prolonged erection): what is happening and when to seek treatment [57:15];
  • Shockwave therapy as a treatment for ED [1:02:45];

  • Methods for increasing endogenous testosterone [1:38:45];
  • Testosterone replacement therapy: various forms of exogenous testosterone, weighing risk vs. reward, and more [1:52:30];
  • The physiology and purpose of testosterone and DHT, why some men feel fine even with “low” testosterone, personalized approaches to treating low testosterone, and more [2:02:30];
  • Post-finasteride syndrome [2:09:00];
  • The role of testosterone in prostate cancer and addressing the notion that TRT could increase risk [2:16:15];
  • The effects of testosterone as an adjunct to therapy for estrogen-sensitive breast cancer in women [2:27:15];
  • Resources for those looking for healthcare providers [2:28:45]; and
  • More.


Mohit’s career path and interest in sexual medicine and infertility [3:00]

Can you tell us about your background and what you did after medical school as it relates to your current work?

  • Mohit went to Vanderbilt for college, after which he attended Boston University where he got his Master’s of Business Administration (M.B.A.) and Public Health (M.P.H.)
  • After working as a healthcare analyst for two years and not quite enjoying it, he decided to change the course of his career path
  • Mohit then went to the University of Texas, San Antonio for medical school, after which he did a one-year internship in general surgery at Baylor College of Medicine and spent five years in urology
  • He then did a one-year fellowship in male reproductive medicine surgery, where he developed a keen interest in sexual health and infertility
  • Mohit has been a faculty member at Baylor since 2007

What are the different aspects of urology, and could you share some insights on what the fellowship experience in urology is like, particularly related to reproductive and sexual health?

  • Peter notes that from his experience, urology places a significant emphasis on urologic cancers such as prostate cancer, bladder cancer, and kidney cancer 
    • However, since his exposure to urology was limited, he wasn’t able to see much of the other aspects of the field, particularly those related to reproductive and sexual health 
  • Mohit explaines that urology is a diverse field with multiple subspecialties and areas of expertise in urology include stones, cancer, and female urology, among others 
    • However, sexual medicine and infertility are important subspecialties in urology as well
    • Reproductive medicine involves procedures such as vasectomy reversals, varicocele repair, and sperm retrieval
    • Sexual medicine focuses on addressing issues such as erectile dysfunction, premature ejaculation, Peyronie’s disease, and hypogonadism
  • Mohit has dedicated his career and research efforts to sexual medicine


The anatomy of the male genitalia [5:45]

Can you briefly go over the anatomy relevant to the male sexual health? 

  • The penis is not a single organ, but rather a combination of three distinct organ systems: the urinary system, reproductive system, and sexual system
  • The urinary system includes the bladder and urethra
  • The reproductive system includes the prostate 
  • The corpora cavernosa are smooth muscle bodies responsible for erections and are located above the urethra
  • The urethra is responsible for urinary function

  • This system is holistic, and each component has the potential to affect the others
