Dihydrotestosterone And The Prostate: The Scientific Rationale For 5α-Reductase Inhibitors In The Treatment Of Benign Prostatic Hyperplasia

Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.

Dutasteride is recommended for men on testosterone replacement therapy (TRT) with DHT-sensitive hair, as it does not interfere with TRT's anabolic effects and may improve libido and aging male symptoms. Users report varying experiences with libido when switching from finasteride to dutasteride, with some noticing improvements and others experiencing fluctuations.

Finasteride is the most effective treatment for reducing DHT and addressing hair loss compared to fish oil and saw palmetto. Topical treatments like RU58841 and minoxidil are also discussed, but finasteride remains the most effective option.

The conversation discusses using finasteride, dutasteride, RU58841, and testosterone to combat hair loss and block DHT, with some users expressing concerns about side effects and vegan options for medication. The discussion also touches on personal experiences with hormone treatments and the desire to maintain a youthful appearance.

The user experienced improved libido and erections after reducing DHT levels with 0.5mg of dutasteride once a week, despite previous side effects from finasteride. They are also on testosterone replacement therapy and have not noticed major personality changes.

Dutasteride may inhibit androgen receptors in addition to reducing DHT, potentially explaining its effectiveness over finasteride for hair loss. Concerns about its impact on muscle growth are debated, with some suggesting no significant effects.
