Huberman Lab Clips(@HLPClips):Chronic cannabis use lowers testosterone: - Smoking marijuana raises prolactin in men and women which pulls down dopamine and testosterone - Chronic means more than twice a week. It also elevates aromatase the enzyme that converts testosterone into estrogen - That is part of why gynecomastia shows up in about 35% of males - If your levels still look fine you either started with a high ceiling or you carry very little aromatase @hubermanlab
