    TLDR Finasteride exposure in pregnancy causes genital abnormalities in male rats.
    The study investigated the effects of in utero exposure to finasteride, a 5α-reductase inhibitor, on male rats. The results showed that exposure to finasteride caused external genitalia abnormalities, including hypospadias and decreased anogenital distance. The study suggests that exposure of women of childbearing potential to even low levels of finasteride should be avoided due to the risk of inducing hypospadias in male offspring. The study also highlights the role of DHT in the growth of the perineal region in males.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 3 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.

      A 19-year-old with rapid hair loss since 16 is considering a hair transplant but refuses to take finasteride or any 5α-Reductase inhibitors. They are currently using minoxidil, tretinoin, and microneedling with a Derminator 2, and only want hair until age 27.
