GLP-1s, weight loss and semen quality

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.
