Rethinking Reductase: The Case for Progesterone and DHT Balance in Men

• 0:17–0:48DHT reframed: DHT treated as "the baddie" but is the active hormone (testosterone = prohormone); DHT 2–10x stronger, higher receptor affinity, longer receptor residence.
• 0:54–1:12Blockade industry: "The whole industry is built on blocking this enzyme" — finasteride, dutasteride (stronger), plus natural 5AR blockers.
• 1:20–1:55Cost of blockade: Blocking DHT → mood issues, sleep problems, anxiety (client case on injectable testosterone with these complaints).
• 2:01–2:385AR's other jobs: Converts progesterone → allopregnanolone; balance required across estrogens, bile acids, glucocorticoids.
• 2:46–4:045β-reductase: Generally tones hormones down for excretion — except bile, which absolutely requires 5β-reductase; novel point for the corpus.
• 4:11–4:23Testing: DUTCH test reports 5α and 5β metabolites.
• 4:30–5:34Rebalancing: No 5β blockers exist; high 5β → stimulate 5α (DHT positive feedback); low 5β → bile supplementation (positive feedback loop).
• 5:49–6:40Allopregnanolone pathway: Progesterone →(5AR)→ 5α-DHP → allopregnanolone is the rate-limiting route; allo effects: sleep, GABA activity, mood stabilization, neuroprotection; brexanolone IV for postpartum depression; oral version in development.
• 6:47–7:46PFS evidence: Stacking natural 5AR blockers can over-block; PFS in young men on Propecia — sexual dysfunction, moodiness, suicides; cited researcher found brains of finasteride-treated lacked allopregnanolone: "there's not enough progesterone there to give them any allo in their brains."
• 7:52–8:34The balance model: "5-alpha reductase is really the director" — balance between allo and DHT requires adequate progesterone substrate; driving androgen effect without enough progesterone → "very, very lopsided."
• 8:39–10:46Progesterone for men: Competes for 5AR → balanced allo + DHT output; "Progesterone for Men" Facebook group reports libido improvements; counters concern that progesterone blocks testosterone ("I don't believe it is"); safer modulation than aggressive 5AR blockade.
