    TLDR Finasteride exposure harms tadpole reproduction and hormone balance.
    Exposure of Xenopus laevis tadpoles to finasteride, an inhibitor of 5-α reductase activity, impairs spermatogenesis and alters hypophyseal feedback mechanisms. The study found that exposure to finasteride led to a decrease in testicular size and sperm count, as well as changes in the levels of hormones involved in the hypothalamic-pituitary-gonadal axis. These findings suggest that finasteride may have negative effects on reproductive function in amphibians.

      community Andrew Schulz stated he had been using a ‘’hair pill’’ for 15 years and it may have caused him infertility

      in Satire  134 upvotes 1 year ago
      The conversation discusses the potential link between hair loss treatment pills, specifically finasteride, and infertility. Users share their experiences and opinions, with some suggesting that finasteride can temporarily lower sperm count, while others argue that other factors like age and lifestyle could also contribute to infertility.

      community DHT/Testosterone levels in scalp Fin VS Dut.

      in Finasteride/Dutasteride  60 upvotes 4 months ago
      Dutasteride raises scalp testosterone by 99%, which may not be ideal for those sensitive to all androgens. Some argue finasteride's balancing act might be better, while others believe dutasteride is superior for hair regrowth.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 2 months ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
