About The Testosteronology Society™

Advancing the Highest Standard of Care in Testosterone and Androgen Medicine

The Testosteronology Society™ was created to elevate clinicians and clinical teams who prescribe and manage Testosterone Replacement Therapy (TRT), androgens, PED-related care, and metabolic or hormone-driven conditions. Its purpose is simple: to provide the most complete, structured, and clinically rigorous education in patient-centered medicine available anywhere in the world for men and women on androgens.

This organization is the result of 20 years of vision and leadership from Dr. Thomas O’Connor, whose work has helped shape the global conversation around responsible androgen care, anabolic-steroid induced hypogonadism, and long-term management of male hormone optimization.

Today, TRT and androgen-related patient populations are rapidly increasing, yet most clinicians were never given comprehensive training in the risks, complexities, and nuances involved. Testosteronology® fills that gap by creating a dedicated subspecialty designed for modern practice.

Becoming a Certified Testosteronologist® allows clinicians to deliver safer, smarter, and more effective care—while gaining a deeper understanding of the endocrine, metabolic, cardiovascular, and pharmacologic considerations involved in treating patients with testosterone and androgens.

What Is Testosteronology®?

The First Dedicated Subspecialty for Testosterone and Androgen-Focused Clinical Care

Testosteronology® is the structured clinical discipline for evaluating, diagnosing, treating, and monitoring patients whose care involves:

• Testosterone Replacement Therapy (TRT)
• Androgens and anabolic agents
• Performance-enhancing drug (PED) use using a harm reduction approach
• Anabolic-steroid induced hypogonadism (ASIH)
• Metabolic and cardiovascular risk factors influenced by hormone therapy
• Male and female androgen optimization
• Ancillary tests and medications used alongside testosterone and androgen protocols

This discipline provides clinicians with a repeatable clinical framework, deeper understanding of hormone-driven physiology, and the tools needed to treat complex populations safely and effectively.

Membership gives clinicians access to a complete educational ecosystem that enhances skill, confidence, and standards of care across every type of patient.
