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
