GLP-1 & PCOS Breakthroughs: How Ozempic is Changing Women’s Health | Dr. Melanie Cree
The Dr. Gabrielle Lyon Show
Navigating Testosterone Testing for PCOS
This chapter explores the complexities of testosterone testing and its critical role in diagnosing conditions such as PCOS. It emphasizes the importance of using sensitive testing methods and considers factors like timing and weight, while also promoting sleep-enhancing bedding products.
In this episode, I’m joined by Dr. Melanie Cree—physician-scientist, pediatric endocrinologist, and one of the leading researchers redefining how we understand and treat Polycystic Ovary Syndrome (PCOS). PCOS affects millions of women, yet it's still underdiagnosed, misunderstood, and often mistreated. Dr. Cree cuts through the confusion, offering a deeply scientific yet compassionate look at what’s really driving this complex condition—from insulin resistance and mitochondrial dysfunction to skeletal muscle quality and fertility trajectories across a woman’s lifespan.
We cover:
- Why PCOS isn’t a single disease—and what two phenotypes may explain the full picture
- How muscle, liver, and fat interact in PCOS
- The misunderstood role of testosterone, insulin, and SHBG in diagnosis
- What muscle biopsies reveal about teenage girls with PCOS
- Intramuscular fat, mitochondrial impairment, and the true cost of sedentary muscle
- How early lifestyle and exercise interventions could change the future of PCOS care
- What GLP-1 agonists and amino acid supplements might offer for treatment
Whether you’re a clinician, patient, or advocate for women’s health, this episode will give you a whole new lens on PCOS—and why skeletal muscle may be the most overlooked (and powerful) organ in the conversation.
