Exploring Testosterone Therapy in Women's Health

In today’s episode, I sit down with Professor Susan Davis, an endocrinologist and one of the world’s foremost experts on hormones in women’s health. We explore the role of testosterone in women, separating fact from fiction, and tackling the common myths that circulate online and in the media.

Susan shares what decades of research actually show about testosterone therapy, its benefits, limitations, and safety, and why participation in clinical trials is essential for moving the science forward.
