    TLDR Dutasteride and finasteride don't raise erectile dysfunction risk.
    A UK study published in the BMJ found that treatment with 5-α reductase inhibitors for alopecia or benign prostatic hyperplasia (BPH) does not increase the risk of erectile dysfunction (ED). The study used data from the UK Clinical Practice Research Datalink and evaluated the risk of ED in 71,849 men ≥40 years of age with BPH receiving 5-a reductase inhibitors (dutasteride or finasteride) alone, or 5-a reductase inhibitors + α-blockers, or a-blockers alone; and in 12,346 men 18-59 years of age with alopecia receiving finasteride or no treatment. The study concluded that 5-a reductase inhibitors do not increase the risk of clinically meaningful incident erectile dysfunction or non-erectile dysfunction sexual dysfunction in men who are free of sexual dysfunction and major risk factors.

      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.
