    TLDR Researchers created a new mouse model, G4, that mimics human PCOS symptoms and links the condition to a specific gene.
    In 2019, researchers introduced a new transgenic mouse model, G4, for studying polycystic ovary syndrome (PCOS), a common hormonal disorder in women of reproductive age characterized by irregular menstrual periods, excess androgen, and polycystic ovaries. The G4 model exhibits obesity, glucose and insulin intolerance, sub-fertility, and increased bone mass, mimicking human PCOS symptoms. The gene disrupted in this model, Gm10800, is believed to be the mouse equivalent of the human gene PIRO, which may play a role in osteoclast formation. This discovery marks the first time a direct link between a gene and PCOS has been established, making the G4 model a valuable tool for understanding PCOS and testing new treatments, such as endoplasmic reticulum stress inhibitors.

      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.
