The Sex Factor

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.

“This book is an empowering reminder that great sex and great health are not separate goals.”—Mary Claire Haver, MD, New York Times bestselling author of The New Menopause

As Dr. Mohit Khera, a pioneering urologist who has helped thousands of people, explains, sexual vitality—the combination of desire, function, connection, and intimacy—is connected to cardiovascular health, diabetes management, and mental wellness, among other barometers of health. When thriving, sexual vitality often reflects a healthy body and mind. When it begins to fade, a deeper health problem may be developing.

In The Sex Factor, Dr. Khera draws on cutting-edge science to help you and your partner assess your present sexual health, offering a detailed plan to help you protect and strengthen it, including

• how diet, exercise, sleep, and stress-reduction impact sexual wellness
• research-backed information on the use of testosterone supplementation for both men and women
• lifestyle and medical strategies for improving libido at any age
• the psychosocial factors at play in a person’s sexual arousal and how to begin talking with your partner about your needs

Your Sex Factor is not something you lose—it is something you can build 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. The Sex Factor will help you envision and pursue years of passion and intimacy—not simply a longer life, but richer, more connected, and more fully alive.
