3α-Dihydroprogesterone (3α-DHP), also known as 3α-hydroxy-4-pregnen-20-one, is an endogenous neurosteroid.[1] It is biosynthesized by 3α-hydroxysteroid dehydrogenase from progesterone.[1] 3α-DHP has been found to act as a positive allosteric modulator of the GABAA receptor and is described as being as active as allopregnanolone in regard to this action.[1] In accordance, it has anxiolytic effects in animals.[2] 3α-DHP has also been found to inhibit the secretion of follicle-stimulating hormone (FSH) from the rat pituitary gland, demonstrating possible antigonadotropic properties.[1] Unlike the case of most other inhibitory neurosteroids, 3α-DHP production is not blocked by 5α-reductase inhibitors like finasteride.[1]
