    TLDR Androstanediol glucuronide is a reliable marker for hirsutism in women.
    The document discussed the metabolism of androgens in women, focusing on androstanediol glucuronide (3aAdG) as a marker for peripheral androgen formation and hirsutism. It found that most circulating testosterone in women came from androstenedione conversion. Elevated 3aAdG levels were observed in hirsute women, making it a reliable marker for hirsutism, unlike plasma DHT. Studies with 54 women (30 idiopathic hirsutism, 24 PCO) supported 3aAdG as an indicator of peripheral androgen action. The study showed significant 3aAdG production in hirsute women with PCOS and highlighted the role of peripheral tissues, particularly skin, in androgen metabolism. It also noted that 5α-reductase activity (5αRA) was crucial and could be inhibited by steroids like spironolactone, though this did not reduce serum 3aAdG levels. The research contributed to understanding the endocrine control of male phenotypic development and conditions like idiopathic hirsutism.

      The post and conversation are about a user's experience with hair loss treatments, specifically switching from finasteride to dutasteride. The user experienced significant hair shedding after the switch, with others suggesting patience, noting similar experiences, or questioning the user's decision and medical consultation.

      community Bile Acid-Mediated DHT Dysregulation Hypothesis

      in Research/Science  13 upvotes 2 months ago
      Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.
