Essentials: How Hormones Shape Sexual Development

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