How Hormones Shape Sexual Development | Huberman Lab Essentials

In this Huberman Lab Essentials episode, I explain the crucial role hormones play in shaping the sexual development of both the brain and body.

I discuss how biological masculinization and feminization depend on factors such as genetics, hormone ratios, and receptor availability. I also explore how hormones like testosterone, estrogen, and other steroid hormones influence sexual characteristics and brain development. Additionally, I examine the impact of environmental factors—such as herbicides like atrazine, cannabis, alcohol, and even cell phones—on hormone function and reproductive health.

Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on key science and protocol takeaways from past Huberman Lab episodes. Essentials are released every Thursday, while full-length episodes continue to be released every Monday.
