    TLDR Certain brain hormones and chemicals are linked to the development of Polycystic Ovary Syndrome.
    The document discusses the role of neuroendocrine determinants in Polycystic Ovary Syndrome (PCOS), a common endocrine disorder in women. It highlights the role of neurohormones such as Gonadotropin-releasing hormone (GnRH), kisspeptin, and Neurokinin B (NKB), and neurotransmitters in the development of PCOS. The document reveals that women with PCOS have a persistent rapid GnRH pulse frequency and higher serum kisspeptin levels, suggesting overactivity in the kisspeptin system. This overactivity leads to hypothalamic-pituitary-gonadal axis overactivity, menstrual disorders, hyperandrogenemia, and hyperandrogenism. Abnormal regulation of NKB is also suspected to contribute to PCOS development. The document concludes that further studies are needed to fully understand the neuroendocrine mechanisms behind PCOS.

      A 29-year-old woman is experiencing gradual hair thinning since age 15, suspects Androgenic Alopecia, and has tried 5% minoxidil with little success. She has purchased various hair loss treatments including minoxidil, dutasteride, finasteride, and spironolactone, but is cautious about starting them due to potential interactions with her ADHD medication.

      community Female, 30, PCOS diagnosis, MPB Norwood 2. Endo refuses to give anything other than Spironolactone. Feel like I’m at my wit’s end here.

      A 30-year-old female with PCOS and male pattern baldness is frustrated with her endocrinologist's recommendation of only Spironolactone and minoxidil, feeling that dutasteride, finasteride, and progesterone would be more effective. Other users suggest various online sources for treatments, warn against self-medicating due to potential risks, and recommend seeking a specialized endocrinologist or considering additional treatments like Inositol, Berberine, and dermaneedling.
