    TLDR Low androgen levels reduce nitric oxide production in rat penile cells.
    The study explored the impact of dihydrotestosterone (DHT) on extracellular vesicles (EVs) from endothelial cells in the rat penile corpus cavernosum, involving five male Sprague Dawley rats. It found that higher DHT levels were associated with increased EV content and protein expression, such as CD9, CD63, TSG101, and eNOS, which are crucial for erectile function. Low DHT levels inhibited the release of eNOS-expressing EVs and reduced nitric oxide (NO) production, potentially contributing to erectile dysfunction (ED) by decreasing NO in penile tissue. The research suggested that EVs might influence erectile function by inhibiting apoptosis in endothelial and smooth muscle cells, and recommended further studies to explore EVs' potential in improving erectile function in ED patients with low androgen levels.

      A serum containing Centella asiatica extracellular vesicles, IGF-1, FGF-7, and caffeine significantly improved hair thickness, density, length, and reduced hair loss after 56 days. The conversation also discusses how treatments like finasteride, minoxidil, and ketoconazole address different aspects of hair loss by reducing DHT, improving blood flow, and lowering inflammation.

      Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

      Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
