    TLDR Taking finasteride for benign prostate hyperplasia may increase the risk of osteoporosis, especially at higher doses.
    In a population-based nested case-control study from 2014, researchers investigated the association between the use of 5-alpha-reductase inhibitors (5 ARIs), specifically finasteride and dutasteride, and the risk of osteoporosis diagnosis in patients with benign prostate hyperplasia (BPH). The study included 1,352 cases of osteoporosis diagnosis and 5,387 controls without an osteoporosis diagnosis from the Taiwanese National Health Insurance Research Database. The results showed that patients with BPH using finasteride had a 1.52-fold increased risk of being diagnosed with osteoporosis (95% CI, 1.01–2.30). Additionally, higher doses of finasteride were associated with an even greater risk of osteoporosis diagnosis (OR = 1.68; 95% CI, 1.01–2.81) compared to patients not using 5 ARIs. The study concluded that finasteride use could increase the risk of osteoporosis diagnosis in patients with BPH, particularly at higher doses.

      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.

      Hair loss treatments like finasteride, minoxidil, and dutasteride work but have side effects. A permanent cure is still not available due to the complexity of hair loss and limited investment.
