    TLDR Vitamin D helps improve PCOS by aiding insulin function and ovarian health.
    Polycystic ovary syndrome (PCOS) is the most common endocrinological disorder in women of childbearing age, affecting 10% of this population. The study covers the diagnosis, clinical symptoms, pathophysiology, hypovitaminosis D, insulin resistance, and the various methods for vitamin D and insulin assessment in relation to PCOS. The disorder is diagnosed based on androgen hypersecretion, oligo-ovulation, and/or ovarian morphologic features, with its pathophysiology involving androgen excess, neuroendocrine causes, and insulin resistance. Vitamin D has been shown to have a positive impact on PCOS and other female reproductive diseases, as it is essential for insulin regulation of steroid biosynthesis in the ovaries and follicular maturation. Furthermore, vitamin D receptors have been found in some female genital organs.

      High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.

      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.
