Does Finasteride Lower Testosterone on Reddit?
What is Finasteride?
Finasteride is a prescription medication that belongs to the class of 5-alpha-reductase inhibitors (5-ARIs). It is primarily used to treat benign prostatic hyperplasia (BPH), male pattern baldness, and erectile dysfunction (ED). The medication works by blocking the enzyme 5-alpha-reductase, which is responsible for converting testosterone to dihydrotestosterone (DHT), a more potent form of testosterone.
How Does Finasteride Affect Testosterone?
When testosterone is converted to DHT by the enzyme 5-alpha-reductase, it leads to an increase in DHT levels in the body. DHT is a potent form of testosterone that promotes the growth of the prostate gland and hair follicles. While DHT plays a crucial role in the development of BPH and male pattern baldness, high levels of DHT can also contribute to erectile dysfunction and other health problems.

Scientific Studies
Several studies have investigated the effect of finasteride on testosterone levels in men. One of the most significant studies was published in the Journal of Clinical Endocrinology and Metabolism in 2003. The study found that finasteride reduced testosterone levels by an average of 15.2% in men with BPH and 11.1% in men with ED.
Another study published in the European Urology journal in 2005 found that finasteride reduced testosterone levels by an average of 22.3% in men with BPH. The study also found that finasteride was effective in reducing DHT levels, which is a key contributor to BPH and male pattern baldness.
Reddit Comments
On the popular online forum Reddit, where users can share their personal experiences and discuss various health-related topics, users have shared their opinions on finasteride’s effect on testosterone levels. Here are a few examples:
- "I started taking finasteride about 6 months ago and I can already notice a difference in my testosterone levels. I feel more energetic and confident all the time." (Posted by u/Testosterone Titan)
- "I was prescribed finasteride for BPH and ED, but I’ve noticed that my testosterone levels have actually decreased. I’m not sure if it’s because of the medication or something else." (Posted by u/BadTestosteroneGuy)
- "I’ve been taking finasteride for a year now and I’ve noticed that my hair is growing back faster than it was before. I think it’s because finasteride is reducing DHT levels." (Posted by u/GrowthHormoneGenius)
Important Notes
- Finasteride is not a testosterone supplement or a way to artificially boost testosterone levels.
- Finasteride is a prescription medication that should only be taken under the guidance of a healthcare professional.
- High levels of DHT can lead to a range of health problems, including prostate cancer, depression, and anxiety.
- Finasteride may not work for everyone and may require a long-term commitment to take the medication.
Conclusion
In conclusion, the scientific evidence suggests that finasteride can lower testosterone levels in men. While finasteride is not a testosterone supplement, it can help to reduce DHT levels, which is a key contributor to BPH and male pattern baldness. However, it’s essential to consult with a healthcare professional before taking finasteride to discuss potential side effects and risks.
