Brain differences in homosexuality?

Andrew Huberman discusses the evidence of brain differences in individuals who self-report as homosexual. A notable study by Simon Levay found that there are differences in the interstitial nucleus of the anterior hypothalamus (INAH) in these individuals. The research indicates that early hormonal exposure can organize brain development in ways that might influence sexual preference later in life. However, it's crucial to understand that these findings are correlational and not causal, meaning they do not definitively determine sexual orientation 1 2.
