Episode notes
Local Treatments For DHT-Related Hair Loss
- If you want to limit scalp DHT but avoid systemic side effects, consider localized approaches like dutasteride mesotherapy.
- Avoid systemic DHT suppression unless medically indicated due to risks to mood, libido, and other tissues.
Recognize And Treat PCOS By Phenotype
- Suspect PCOS when women have androgen excess, insulin resistance, or oligomenorrhea and evaluate with Rotterdam criteria.
- Treat insulin resistance first; use metformin or myo‑inositol/d‑chiro‑inositol selectively based on phenotype.
Substances That Shift Sex Hormone Balance
- Smoked marijuana can increase aromatase and raise estradiol, indirectly lowering LH/FSH and testosterone.
- High alcohol and strong GABA agonists also depress testosterone via central mechanisms.
