Male fertility is declining, and most men have no idea why.

In this episode of The Dr. Gabrielle Lyon Show, Dr. Gabrielle Lyon sits down with Dr. Michael Eisenberg, Director of Male Reproductive Health at Stanford University and Chief Medical Advisor of SwimClub, to break down what truly determines sperm health and reproductive success.

They discuss:

1. How metformin, GLP-1 medications, testosterone therapy, and anabolic steroids affect male fertility
2. Why sperm count is a powerful biomarker for long-term health and longevity
3. The role of sleep, muscle mass, exercise, diet, marijuana, and environmental toxins like microplastics
4. Whether platelet-rich plasma, or PRP, can help severe male infertility
5. Daily habits that quietly reduce a couple’s chances of conceiving

If you care about fertility, hormones, metabolic health, or the future of men’s health, this conversation is essential.

Self-doubt holds more people back than lack of skill or intelligence.

In this episode, Dr. Gabrielle Lyon sits down with Dr. Shadé Zahrai to explore the science of confidence, self-trust, and peak performance. They break down why confidence comes after action, how self-image shapes success, and the four psychological drivers that determine whether you thrive or stay stuck.

You will learn how body language influences perception, why high performers plan for failure, how perfectionism leads to burnout, and the subtle communication habits that undermine credibility. Most importantly, you will discover how to build what Dr. Zahrai calls Big Trust so you can back yourself before you feel ready.

If you struggle with overthinking, imposter thoughts, or feeling capable but not fully confident, this conversation will give you practical tools to change how you show up.
