Men & Progesterone: Why You Should Avoid This Hormone Like the Plague

If you’ve been digging into hormone optimization lately, you might’ve come across some surprising (and misleading) advice about men and progesterone. Between online forums and one-size-fits-all treatment plans, there’s a growing wave of confusion. 

One of the more concerning health trends we’ve seen lately? Men being told to take progesterone.

Yes, progesterone, the hormone best known for supporting pregnancy in women. Some men are getting tested, seeing “low” numbers, and assuming it needs to be raised. But progesterone has no business being in a man’s supplement or treatment plan, and we’re here to explain why.

We recently sat down with Dr. Lauren Fitz and Kristi Hales on the Women Want Strong Men podcast to discuss why progesterone is not only unnecessary, but potentially dangerous for men. Check it out below, then keep reading for more on why you should avoid this hormone.

What is Progesterone? Why Do Women Need It, But Not Men?

Let’s start with the basics. Progesterone is a pro-gestational hormone, which  means its primary role is to support fertility and pregnancy. It’s naturally produced in large amounts in women, particularly during the second half of the menstrual cycle and during pregnancy.

Men have trace amounts of progesterone, but it serves little to no functional purpose in the male endocrine system. Those low levels are normal, natural, and necessary—they don’t need to be fixed or “optimized.”

Unlike testosterone, which fuels energy, libido, muscle mass, and mood in men, progesterone plays no supportive role in men’s health. When it’s added in through supplementation, it can throw your system way out of balance. In the next section, we’ll explain why.

Why Progesterone Is Dangerous for Men

While men naturally produce small amounts of progesterone—and that’s completely normal—taking progesterone as a supplement can actually work against your health goals. Unlike what some misguided advice might suggest, supplementing with progesterone can interfere with key functions like testosterone production, blood flow, and metabolism.

It’s one of the few hormones where the potential downsides far outweigh any perceived benefits, and most men have no idea what they're walking into when they start taking it. Let’s take a closer look at why progesterone is dangerous for men. 

Side Effects of Progesterone in Men

When men take progesterone, they may experience:

• Inflammation – Progesterone raises inflammatory markers in men, which increases the risk of heart disease and other chronic conditions.
• Cardiovascular risk – According to pharmacist Kristi Hales, it can directly raise your risk of a major cardiovascular event.
• Metabolic dysfunction – Supplementing progesterone can worsen blood sugar regulation and increase body fat, especially around the midsection.
• Hormonal suppression – It can suppress testosterone production, worsening symptoms of low T rather than fixing them.
• Mood and energy crashes – Many men feel more fatigued, emotionally flat, or even depressed after taking progesterone.

Progesterone and Erectile Dysfunction

If you’re taking progesterone and wondering why your libido disappeared—it’s probably because progesterone kills the male sex drive. In fact, it was once used as a chemical castration tool in prisons. As Kristi Hales pointed out on the Women Want Strong Men podcast, “If you want to cash in on a man’s life insurance policy, give him progesterone.”

Along with suppressing libido, progesterone can also cause erectile dysfunction by interfering with nitric oxide and testosterone pathways. 

Sure, some guys report deeper sleep from progesterone, but that’s not worth sacrificing your sex drive or cardiovascular health. There are safer, more effective ways to support sleep (like melatonin, diet changes, or optimizing testosterone).

Progesterone & Hormone Forums: Misinformation Alert

A quick browse through TRT forums or online male hormone groups will show just how common the misinformation is. Men are testing progesterone levels, seeing that they’re “low,” and assuming they need to raise them. But guess what?

Progesterone is supposed to be low in men.

It’s not something that needs to be “brought into range.” Measuring it can be misleading, and supplementing it based on numbers alone is risky business. Worse, some hormone academies and lesser-known training programs are still recommending it, despite the lack of evidence and growing list of harmful side effects.

As Dr. Lauren Fitz and Kristi Hales emphasized on the podcast: if your healthcare provider is recommending progesterone for men, that’s a red flag. It shows a serious lack of understanding of male hormone physiology.

Why You Should Avoid Progesterone Supplements at All Costs

Let’s be clear: no reputable hormone specialist or evidence-based clinic will ever recommend progesterone to a man. If you’re working with someone who’s pushing it—or you’re seeing it recommended in a Facebook group or Reddit thread—it’s time to run the other way.

The risks aren’t just theoretical. Supplementing progesterone as a man can:

• Worsen your testosterone levels
• Cause sexual dysfunction
• Increase your risk of heart attack or stroke
• Leave you feeling foggy, inflamed, and fatigued

There are zero clinical benefits and plenty of potential downsides. There’s simply no upside here—progesterone has no role in male hormone optimization.

So, How Do I Improve My Health as a Man?

“If progesterone isn’t the answer…what is?” Don’t worry, there are powerful, proven ways to support your hormones, energy, libido, and overall well-being without putting your health at risk. 

At Victory Men’s Health, we take a holistic, science-backed approach to hormone optimization. That means focusing on what actually works based on real labs, clinical research, and years of experience helping men feel like themselves again. 

Here are some of the ways you can improve your health (without progesterone): 

• Optimize testosterone – Testosterone replacement therapy (TRT) can dramatically improve mood, strength, libido, and stamina if your levels are low.
• Support thyroid function – Thyroid plays a major role in metabolism and energy, and many providers miss the mark by not testing Free T3. 
• Lower visceral fat – Excess visceral fat raises inflammation and crushes hormone health. It’s most accurately measured with a DEXA scan, but the InBody scales in our clinics also quantify visceral fat, making it easy to track your progress over time.
• Clean up your lifestyle – Diet, sleep, exercise, and removing endocrine-disrupting chemicals (EDCs) can significantly improve hormone balance.
• Work with a qualified provider – Partner with providers who understand male hormones, track real labs, and customize your care, like our team.

Men & Progesterone: What Our Patients Ask

Is Progesterone Ever Safe for Men to Take?

No. There’s no known clinical benefit for men supplementing progesterone. The risks far outweigh any potential use, including increased inflammation and suppressed testosterone.

Why Are Some Providers Still Prescribing It?

Some hormone academies or outdated training programs still recommend progesterone for men, but the science doesn’t support it. If your provider suggests it, get a second opinion.

What Are Signs I’ve Been Negatively Affected by Progesterone?

Loss of libido, erectile dysfunction, fatigue, mood changes, or unexplained inflammation could all be side effects. If you’re a man taking progesterone, stop supplementation and start questioning your provider.

Can Progesterone Lower Testosterone?

Yes. Progesterone can suppress the body’s production of testosterone, leading to worsened symptoms of low T and hormonal imbalance.

What’s the Right Approach for Men Over 40 with Hormone Issues?

A personalized plan that goes beyond just testosterone. Men often need to optimize multiple hormones affected by age-related decline—including DHEA, pregnenolone, melatonin, and testosterone (which also impacts estradiol and DHT levels). 

The most effective approach combines comprehensive hormone support, metabolic testing, and lifestyle improvements, designed by a provider who specializes in men’s health.
