Sexual Security: The Aging Man’s Guide to Lifelong Performance
Sexual health does not exist separately from the rest of a man’s health.
Sexual Security: The Aging Man’s Guide to Lifelong Performance is a comprehensive digital book by Dr. Kathryn Retzler exploring the connections among sexual function, cardiovascular health, hormones, metabolism, aging, and long-term physical performance.
The book examines erectile function and dysfunction, blood-vessel health, testosterone, adrenal and thyroid hormones, laboratory and advanced testing, nutrition, sleep, exercise, body composition, environmental exposures, supplements, and testosterone therapy. It also introduces Dr. Kathryn Retzler’s 8-Step Lifelong Performance Prescription and concludes with a self-assessment questionnaire and additional resources.
Written for men who want to better understand the biology behind changing energy, sexual function, hormones, and health with age, Sexual Security approaches sexual performance as one part of a much broader healthy-aging strategy.
