    TLDR Exposure to too much androgen before birth might cause polycystic ovary syndrome later in life.
    The 2006 document provides evidence that polycystic ovary syndrome (PCOS) may be programmed in the fetus due to exposure to excessive androgens. It references experimental studies with primates, clinical observations in humans with fetal androgen excess disorders, and genetic association studies that link PCOS traits to polymorphic gene variants related to androgen activity. The document also discusses the potential for compromised buffering of maternal androgens by placental mechanisms, fetal contributions to androgen excess, and the influence of genetic factors on androgen levels. It concludes that prenatal androgenization, shaped by both genetic and environmental factors, may predispose individuals to develop PCOS in adulthood.

      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.

      Balding seems to worsen with each generation, possibly due to stress, diet, and environmental factors. The user started treatments like Minoxidil and finasteride.
