About The Testosteronology Society®

Advancing the Highest Standard of Care in Testosterone and Androgen Medicine

The Testosteronology Society® is the professional organization dedicated to advancing the field of Testosteronology®, an emerging clinical discipline focused on testosterone, androgens, anabolic-androgenic steroids, hormone medicine, and the long-term management of patients whose health is influenced by these therapies.

At the center of the Society is the Testosteronology® Professional Education Program, a comprehensive 14-course training program designed to provide clinicians with the structured, evidence-informed framework that has been missing from traditional medical education.

Developed under the leadership of Thomas O'Connor, M.D., Founder and CEO of the Testosteronology Society®, this program represents more than two decades of clinical experience, research, patient advocacy, and frontline management of some of the most complex testosterone and androgen-related cases in medicine.

Today, millions of patients worldwide receive Testosterone Replacement Therapy (TRT), anabolic-androgenic steroids, and other hormone-related therapies. Yet many clinicians have never received formal training in androgen physiology, laboratory interpretation, cardiometabolic risk management, anabolic-steroid induced hypogonadism, fertility preservation, harm reduction, or the long-term monitoring required to manage these patients safely. The Testosteronology® Professional Education Program was created to solve this problem.

The Testosteronology® Professional Education Program

The 14-course curriculum provides clinicians with a structured clinical framework for evaluating, diagnosing, treating, and monitoring patients receiving testosterone therapy, androgens, anabolic-androgenic steroids, and other image and performance-enhancing drugs (iPEDs).

Key areas of study include:

• Testosterone Deficiency and Clinical Diagnosis

• Anabolic-Androgenic Steroid and iPED Use Disorders

• Diagnostic Decision Making and Risk Stratification

• Laboratory Evaluation and Ancillary Testing

• Testosterone Therapy Management

• Harm Reduction and the A.R.M.® Three-Door Framework

• The ABCDS™ Framework

• Testosterone Drug Formulations

• Anabolic-Androgenic Steroid Pharmacology

• Legal, Regulatory, and Compliance Considerations

• The Present and Future of TRT Clinics

• Clinical Reference Systems and Terminology

This is not simply a collection of educational videos. It is a complete clinical framework designed to help providers move beyond protocol-driven medicine and develop the critical thinking skills required to manage increasingly complex androgen patients.

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.
