Notice who contributed to the guidelines?



Methods


The current guideline is structured as a series of Questions & Answers (Q&A) relating to the diagnosis and management of TD. By way of this structure, the guideline offers a practical, evidence-based overview and recommendations related to the diagnosis, treatment, monitoring, risks, and benefits of TD and testosterone therapy. It was designed to be a straightforward and user-friendly guide for specialists (urologists, endocrinologists, psychiatrists, geriatricians), general practitioners, and the patients they treat. The guideline offers Canadian-specific content with respect to knowledge and attitudes related to TD, laboratory diagnostic testing, Health Canada-approved treatment formulations, and funding considerations.


The authorship group represents a panel of Canadian and international experts in the fields of men’s health and TD. Representation is inter-provincial and multi-disciplinary covering the fields of urology, internal medicine/endocrinology, and clinical biochemistry.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
