Disruptors of Androgen Action and Synthesis

    TLDR Certain pesticides and fungicides can interfere with male hormone functions, potentially causing reproductive issues in male rats.
    Various environmental chemicals were found to exert antiandrogenic effects in animals, raising concerns about potential adverse effects in humans. These chemicals could disrupt androgen functions by competing with testosterone and dihydrotestosterone (DHT) for the androgen receptor (AR) or by inhibiting key steroidogenic enzymes like cytochrome P450 17 and steroid 5α-reductase. Notable chemicals include pesticides like p,p-DDE and fungicides like vinclozolin, which caused reproductive malformations in male rats. While many compounds acted as estrogens, few acted as androgen mimics. The human health impact of environmental antiandrogens remained unclear.

      Antiandrogens and androgen inhibitors like spironolactone, finasteride, and dutasteride can treat hair loss and skin conditions, but they have risks and side effects, including potential harm to pregnant women and risks of cancer and heart issues. Herbal remedies also have antiandrogenic effects but lack safety validation.
