Episode Details

Did you know that testosterone is actually the most abundant sex hormone in women's bodies prior to menopause? 

I’m sitting down with Dr. Kelly Casperson, a board-certified urologist and women’s sexual health expert, to tackle one of the most misunderstood hormones in women: testosterone. We explore why testosterone matters for everything from your cellular energy and gym gains to motivation, mood, and libido, plus why a “normal” lab result might not tell the whole story. I also ask the practical questions you need answered about testing, finding the right level for your body, recognizing side effects, and approaching testosterone replacement safely.

(02:07) Testosterone supports cellular and mitochondrial health, helping explain its connection to energy throughout the body.

(02:51) Potential signs of low testosterone, including fatigue, declining gym performance, lower libido, and changes in mood.

(03:34) Kelly describes testosterone as a motivation hormone that may influence much more than sexual desire.

(04:37) Testosterone levels begin declining after your twenties, well before the dramatic hormonal changes associated with menopause.

(05:41) There isn’t one simple “optimal” testosterone number; and timing, dosing, and natural hormone fluctuations complicate lab results.

(07:47) Kelly’s three-part approach to evaluating testosterone treatment: how you feel, whether you experience unwanted side effects, and what your labs show.

(10:18) Learn which blood test Kelly recommends for measuring female testosterone and why some standard testosterone tests may be poorly suited to women’s lower physiologic levels.
