Does Finasteride Lower Testosterone? Unraveling the Truth

Does finasteride lower testosterone? This brings about a considerable measure of controversy.

In fact, when it comes to understanding this drug and its effects on our bodies, there’s one major point of confusion…

Does finasteride lower testosterone or does it actually increase it?

This is the thing that sets apart those who are knowledgeable about their wellbeing from those in obscurity. But if you don’t know how finasteride truly affects your hormone levels, you might never reach a clear conclusion.

The world of hormones can be complex.

Take for instance one man who started taking finasteride to combat hair loss… only to find himself questioning whether his testosterone levels were being affected negatively as a result.

Now he’s worried about continuing with his treatment, not to mention

The Role of Finasteride in Testosterone Levels

Understanding the role finasteride plays on testosterone levels is crucial for those considering this medication. Surprisingly, finasteride may result in an elevation of testosterone levels by 10-20%, as opposed to a decrease.

This rise occurs due to how finasteride works; it inhibits the conversion process from testosterone into Dihydrotestosterone (DHT), a hormone known for its involvement with hair loss.

Total T Clinic, our anti-aging clinic specializing in treatments like TRT and HGH among others, offers more insights about these hormonal changes associated with using medications such as finasteride.

The Connection Between Finasteride and DHT

Digging deeper into the relationship between finasteride and DHT reveals that it’s all about managing enzymes. Specifically, an enzyme called 5-alpha-reductase facilitates the transformation from testosterone to DHT. When inhibited by taking finasteride, there’s a notable reduction around 70% in circulating levels of DHT within your system.

If you’re struggling with male pattern baldness, a condition often linked to high scalp concentrations of DHT, the use of finasteride might help prevent further thinning or even reverse some existing hair loss caused by hormonal imbalances.

Deciphering How Finasteride Works

In the realm of testosterone levels and hair loss treatment, finasteride is a significant player. Finasteride inhibits 5-alpha-reductase, a key enzyme that converts testosterone into DHT, which can help reduce or even reverse hair loss. So, how does this affect you?

This might sound complicated, but the basics are that taking finasteride can help to reduce or even reverse balding.

The Effectiveness of Finasteride Against Hair Loss

Digging deeper into how exactly finasteride works, studies have shown its efficacy against hair loss. Specifically, among men with androgenetic alopecia, who saw an increased hair count after consistent use.

  • An average increase of approximately 107 hairs was observed after just one year on a daily dosage regimen;
  • Maintaining these results requires a long-term commitment to taking medication regularly;
  • Slightly increased levels of certain hormones may be experienced as side effects but generally are not harmful.

Potential Side Effects and Considerations When Taking Finasteride

If considering using finasteride for low testosterone or combating hair loss, consult your healthcare provider first. It’s crucial to discuss potential side effects like erectile dysfunction prior to starting any new medications. While sexual function could be affected temporarily in some cases, most users do not experience major issues. Remember – every individual responds differently, so don’t hesitate to seek professional advice before making a decision.

Potential Side Effects of Taking Finasteride

When it comes to the hormone effects of finasteride, there’s more than just surface level information. While this drug is widely used for treating male pattern baldness and increasing testosterone levels generally, users should be aware of potential side effects.

In essence, while many experience benefits from using finasteride to increase their testosterone levels and combat hair loss, others may encounter sexual side effects.

Comparing Finasteride and Dutasteride

The world of anti-androgens doesn’t stop at finasteride’s doorstep; a similar drug called dutasteride also plays a role in managing low testosterone. However, its mechanism differs slightly.

  • Dutasteride inhibits 3 types of enzymes that convert testosterone into DHT, resulting in an even greater decrease in DHT levels compared to those on finasteride treatment.
  • This increased efficiency could lead to stronger results but might come with higher risks like breast cancer, according to certain reports.

A Note on Hormone Blood Levels and Other Concerns with These Medications:

Considerations When Using Finasteride For Low Testosterone

If you’re considering taking finasteride for low testosterone or to combat hair loss, it’s essential to understand its implications. While this medication can effectively raise your testosterone levels and help manage male pattern baldness, there are key takeaways finasteride users should be aware of.

Prior consultation with a healthcare provider is strongly advised before starting any new medication regimen, as finasteride’s hormone effects could include erectile dysfunction or slightly increased levels of certain hormones.

Compatibility With Testosterone Replacement Therapy

The combination of testosterone replacement therapy (TRT) and finasteride is an area that requires careful thought. The blending of these two medications could result in a heightened level of hormones within the body, potentially causing issues such as decreased libido.

In some instances, coupling TRT with finasteride might amplify sexual side effects, including erectile dysfunction. Therefore, discussing this combination with your healthcare professional is crucial before initiating any new medicinal routine.

Besides, consistent monitoring will be necessary while on both medications simultaneously. This ensures optimal results by maintaining balance in hormone blood levels while mitigating potential risks associated with their interplay-induced hormonal imbalances.


Finasteride, a drug commonly used to combat hair loss, does not lower testosterone. In fact, it increases it.

The key lies in its mechanism of action – blocking the enzyme Type II reductase that converts testosterone into DHT.

This results in decreased scalp concentrations of DHT and interrupts male pattern baldness development.

However, finasteride isn’t without potential side effects such as sexual dysfunction and decreased sex drive. It’s important to weigh these against its benefits before starting treatment.

Dutasteride is another similar drug with more potent effects on hormone blood levels due to inhibiting three types of 5-alpha reductase enzymes compared to finasteride’s one type inhibition.

If you’re considering using finasteride for low testosterone or hair loss treatment, always consult your healthcare provider first. They can guide you through the process while monitoring any changes in your hormonal balance and overall health status.
