Episode Details

The receptor that switches off your appetite on a GLP-1 drug is the same one wired into your reward circuitry, your hormones, and your blood vessels, which means when you turn down hunger, something else may be getting turned down too, and for most people taking these drugs, nobody ever checked.

In this solo episode, Dr. Gabrielle Lyon discusses:

• Why the same drug class can improve sexual function in men with obesity while potentially dampening it in lean or postmenopausal women — and why the deciding factor isn't the drug, it's the body
• How rapid weight loss raises SHBG, the protein that soaks up free testosterone, so a "normal" total testosterone result can hide a real deficit your bloodwork won't flag
• Why women make up 60–70% of GLP-1 prescriptions yet the entire evidence base for female sexual function is two case reports, with zero validated questionnaires in any pivotal trial
• The three-tier action plan for anyone on or about to start a GLP-1 — baseline your sexual function first, get free testosterone tested, and protect muscle with protein and resistance training

Whether you're on a GLP-1 drug or considering one, you'll walk away knowing exactly what to measure before you start and what to watch for after — so a change in your sexual health gets caught as the vital sign it is, instead of being quietly dismissed.
