210. Dr. Rena Malik: Why Erectile Dysfunction Could Be an Early Warning Sign of Heart Disease

What if problems in the bedroom were actually an early warning sign of something much bigger happening in your body?
Most people think of sexual health as separate from their overall health. But erectile dysfunction, low libido, and changes in sexual performance can reveal important clues about cardiovascular health, hormone levels, metabolic function, and even how we're aging.
In this episode, I'm joined by Dr. Rena Malik, a urologist and sexual health expert, to explore why sexual health deserves a much bigger place in the longevity conversation. We discuss her concept of "sex span"—how long we can maintain a healthy, satisfying sex life—and why protecting it may also mean protecting our long-term health.
One of the most eye-opening parts of our conversation is the connection between erectile dysfunction and heart disease. Because the blood vessels involved in erections are smaller than those supplying the heart, vascular problems can sometimes appear as sexual dysfunction years before more serious cardiovascular symptoms develop.
We also break down the truth about testosterone replacement therapy (TRT), Viagra, Cialis, nitric oxide supplements, pelvic floor health, and the psychological factors that influence sexual performance.
In this episode, you'll learn:
Why erectile dysfunction can be an early warning sign of cardiovascular disease
The five major causes of erectile dysfunction—and why low testosterone isn't always the answer
How morning erections and nighttime erections can provide clues about sexual health
The difference between Viagra and Cialis, and what these medications actually do
What to know about testosterone replacement therapy, including its effects on fertility
Whether supplements like L-citrulline and L-arginine can improve erectile function
How pelvic floor health, exercise, sleep, and stress affect sexual performance
How pornography, masturbation, and performance anxiety can influence arousal
Why communication, intimacy, and relationship health matter for maintaining sexual wellness as we age
We also discuss emerging treatments for erectile dysfunction, the importance of identifying underlying health problems rather than simply treating symptoms, and the four pillars of sexual health Dr. Malik explores in her book, The Hard Truth.
The biggest takeaway? Sexual health isn't just about sex. It's another window into your overall health.
When we start treating sexual dysfunction as a potential signal of deeper metabolic, vascular, hormonal, or psychological issues, we create an opportunity to intervene earlier, improve quality of life, and potentially protect our long-term health.
Because longevity isn't just about adding years to your life. It's about preserving the health, connection, and vitality that make those years worth living.
