Effect of 5α-Reductase Inhibitors on Sexual Function: A Meta-Analysis and Systematic Review of Randomized Controlled Trials

Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.

Finasteride and dutasteride, used for hair loss, can cause sexual dysfunction, depression, and suicidal thoughts, with some effects persisting after stopping. The post stresses the importance of being aware of these risks.

The conversation concludes that finasteride, a 5α-Reductase inhibitor used for hair loss, does not impair cognition either short-term or long-term. It suggests "brain fog" is not caused by the medication.

Finasteride not only inactivates the 5a reductase enzyme but also affects the 5b reductase enzyme in a dose-dependent manner, which can impact sexual behavior and brain activity. The user experienced significant hair regrowth and side effects on 1mg of finasteride, which diminished after reducing the dose to 0.5mg, leading to no side effects and further hair improvement.

The release of a study on 5a-reductase inhibitors (finasteride and dutasteride) which showed an increased risk of depression, dementia, decreased libido, and reduced semen load as potential side effects; discussion around other forms of hair loss treatments such as topical minoxidil, RU58841, or opting to accept baldness; and advice to consider professional help for deeper issues related to hair loss.

Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.
