Glossary 3β-Hydroxysteroid Dehydrogenase

enzyme crucial for converting steroid precursors into active hormones

3β-Hydroxysteroid Dehydrogenase (3β-HSD) is an enzyme that plays a crucial role in the biosynthesis of all classes of hormonal steroids, including androgens, estrogens, and glucocorticoids. It catalyzes the conversion of Δ5-3β-hydroxysteroids to Δ4-3-ketosteroids, a key step in the production of hormones that regulate various physiological processes, including hair growth and skin health.

June 2025 in “Journal of Kufa for Chemical Sciences”

In this study, researchers observed increased hormone levels such as testosterone and LH in both obese and non-obese women with Polycystic Ovary Syndrome, but concluded that the enzyme 3βHSD shows poor diagnostic value for PCOS compared to healthy women.

research 17 beta-hydroxysteroid dehydrogenase 3 deficiency in the Mediterranean population.

46 citations , August 2006 in “PubMed”

In this study, researchers identified and examined males with 17 beta-HSD3 deficiency in a highly inbred Arab population, noting genetic findings and the progression of male characteristics despite being raised as females initially.

community Has there been any update or progress on the 3-alpha hydroxysteroid dehydrogenase hypothesis?

13 upvotes 2 months ago

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.

community The theory that explains everything. Please help me make this big!

2450 upvotes 5 years ago

The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

community "but it will hurt my gains bro"

in Satire 1309 upvotes 1 year ago

The conversation humorously discusses hair loss treatments like Minoxidil, Finasteride, and Dutasteride, and their effects on hair and muscle gains. Users debate effectiveness and side effects, mixing scientific approaches with jokes.

community DHT levels after 4 weeks of Fina and 8 weeks of Fina + 4 weeks of Duta

37 upvotes 7 years ago

The user reported early stage diffuse hair thinning and increased DHT levels after 4 weeks on Finasteride and 8 weeks on Finasteride plus 4 weeks on Dutasteride, despite the medications being authentic and stored properly. They are considering increasing their Dutasteride dosage due to the lack of side effects and are unsure if the treatment is helping their hair.
