    TLDR Men may experience long-term sexual dysfunction after stopping Finasteride.
    This study aimed to replicate previous findings on persistent sexual dysfunction in men after discontinuing Finasteride (FIN). Reviewing charts from 2015-2020, 91 men (median age 39) with normal sexual function prior to FIN use and persistent symptoms for over 6 months post-discontinuation were analyzed. The most common symptom was erectile dysfunction (ED), present in 95% of cases, with 77% showing abnormal erectile tissue inhomogeneity on ultrasound. Additionally, 57% experienced orgasmic dysfunction, and 48% had genital anhedonia/anesthesia. Quantitative Sensory Testing (QST) revealed abnormal results in 60% of patients. Hormonal abnormalities included low dihydrotestosterone (DHT) in 30%, low testosterone (T) in 16%, and low calculated free T in 9%. The study confirms persistent physical sequelae in this population, highlighting the need for further research.

      DHT is important for sexual function and mood, but finasteride and dutasteride can reduce DHT, causing side effects like reduced libido and erectile dysfunction. These treatments are effective for hair loss, but their impact on DHT leads to debate.

      The user has been using topical 5% minoxidil for six months with minimal results and is worried about greasy hair and potential side effects of adding finasteride.

      community Why is everyone not directly advised Dutasteride?

      Dutasteride is less commonly prescribed for hair loss because it is not FDA-approved for this purpose, unlike finasteride, which is more accessible and preferred due to fewer side effects. Dutasteride may be more effective in reducing DHT but has a longer half-life and potentially more significant side effects.

      community What can be the real reason of Finasteride SE ?

      in Finasteride/Dutasteride  19 upvotes 7 months ago
      Finasteride can cause side effects like erectile dysfunction and decreased libido, possibly due to increased estradiol from testosterone aromatization, especially in those with higher body fat. Side effects vary widely and may also be influenced by genetic factors or neurosteroid inhibition.
