A leading sexual health physician introduces the groundbreaking concept that your sexual wellness may be the single most overlooked predictor of how well—and fully—you live, with a science-backed plan to maintain and enhance lifelong sexual health.

We all want to live as long as we can, but we should also seek to make those years as rich and fulfilling as possible. In The Sex Factor, Dr. Mohit Khera, a pioneering urologist who has helped thousands of men and women, asserts that sexual health—the combination of desire, function, connection, and intimacy—is a window into our overall health. When thriving, it often reflects a healthy body and mind. When it begins to fade, a deeper health problem may be developing.

In this revolutionary approach to longevity and sexual health, Dr. Khera draws on cutting-edge research to reveal the connections between sexual vitality and the key pillars of wellbeing, including cardiovascular health, diabetes management, and mental wellness. With research-backed help for fluctuating hormones, lifestyle and medical solutions for improving libido, and smart strategies for keeping the flame alive at any age, The Sex Factor will help you envision and pursue years of passion and intimacy. Your Sex Factor is not something you lose—it is something you protect, build, and strengthen throughout your life. Every healthy choice, every conversation you have with your partner or your physician, every step you take toward improving your physical, emotional, and relational health is an investment in it.

By reframing sex as an indicator of overall health and longevity, Dr. Khera destigmatizes sexuality and offers hope for overcoming sexual dysfunction in both men and women. By working to improve and maintain your Sex Factor, you will not see sexual health as a luxury or an afterthought, but as an essential part of living well—not simply longer, but richer, more connected, and more fully alive.
