Structure and Expression of a New Complementary DNA Encoding the Almost Exclusive 3β-Hydroxysteroid Dehydrogenase/Δ5-Δ4-Isomerase in Human Adrenals and Gonads

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.

The conversation discusses the molecular structures of compounds that reduce DHT levels, including finasteride and Ashwagandha. It explores the potential of using Ashwagandha topically as a 5a reductase inhibitor.

Finasteride has no effect on the user's estradiol levels, and body fat may influence aromatization. The user is on testosterone replacement therapy and uses everyday injections to manage high RBC count, with plans to measure DHT, DHEA-S, and pregnenolone levels.

The conversation discusses that dutasteride may be more effective than finasteride for frontal hair loss due to higher 5ar Type 1 enzyme activity in that area. Some users question the validity of this information, while others confirm it with additional sources.
