Cordyceps may modestly support testosterone production, based largely on cell culture and animal studies, though human research remains limited and inconsistent. The fungus became widely recognized after a popular post-apocalyptic TV series used it as a fictional pandemic trigger, but the real-world cordyceps used in supplements is a completely different story, one rooted in traditional medicine and emerging, though still early-stage, scientific interest.
If a fictional fungal apocalypse got you curious about what cordyceps actually does in the real world, here’s an honest look at the testosterone research.
What Is Cordyceps, Really?
Cordyceps is a genus of parasitic fungi that has been used in traditional Chinese medicine for centuries, primarily for fatigue, immune support, and vitality. In nature, certain cordyceps species infect insects, but the cordyceps used in human supplements is cultivated separately and poses no risk of the fictional scenario popularized in entertainment. The two most studied species in supplements are Cordyceps sinensis and Cordyceps militaris.
Important context: despite the dramatic fictional premise that made cordyceps a household name, there is no scientific basis for human-infecting fungal pandemics. The real research on cordyceps focuses on far less dramatic topics, including hormone support and athletic performance.
What the Research Shows About Testosterone
This is where it’s important to be precise about the evidence:
Cell culture (in vitro) studies:
- Some studies on isolated Leydig cells, the testosterone-producing cells in the testes, show cordyceps extracts increasing testosterone secretion and cell proliferation
- A 2024 study found that a specific cordyceps extract significantly increased cell proliferation and testosterone secretion through activation of a hormone-signaling pathway
Animal studies:
- A 2020 study in rats found that cordyceps mushroom cultures may improve testosterone, erectile function, and sex drive
- Research in rodents has shown cordyceps can dose-dependently increase testosterone levels when administered orally
Human studies:
- Direct human research on cordyceps and testosterone is notably limited
- Some research suggests a possible mechanism through luteinizing hormone (LH), which signals the testes to produce testosterone, but confirmatory human trials are lacking
The honest summary: the cellular and animal evidence is promising and mechanistically plausible, but robust, well-controlled human studies are still needed before strong claims can be made.
Other Reported Benefits Beyond Testosterone
Cordyceps has more established research behind several other benefits:
- Athletic performance. Some studies suggest cordyceps may improve oxygen utilization and exercise capacity, which is part of why it gained popularity among athletes.
- Fertility support. Research suggests cordyceps may improve sperm count and motility in some contexts.
- Antioxidant properties. Cordyceps contains compounds studied for their potential to protect cells from oxidative stress, including in reproductive tissue.
Should You Try Cordyceps for Testosterone?
Given the current state of research, here’s a reasonable framework:
Cordyceps may be worth considering if you:
Want to try a low-risk, traditional supplement alongside other lifestyle changes
Are interested in potential athletic performance or fertility support, where the supporting research is somewhat stronger
Understand that testosterone-specific benefits are not yet well-established in humans
Cordyceps is not a substitute for medical treatment if you:
- Have symptoms consistent with clinically low testosterone
- Are looking for guaranteed or significant hormone changes
- Have not yet confirmed your actual testosterone levels through bloodwork
How to Know If You Actually Need More Than a Supplement
Supplements like cordyceps work within your existing hormonal range at best. They cannot correct a genuine testosterone deficiency. If you’re experiencing symptoms of low testosterone like persistent fatigue, low libido, or muscle loss, a blood test is the only reliable way to know where you stand.
When Medical Treatment Makes More Sense
For men with confirmed low testosterone, testosterone replacement therapy offers predictable, well-researched results that supplements simply can’t match. Treatment options include injections, gels, and pellet therapy, typically structured as monthly programs including labs and physician oversight. Pricing commonly starts in the low hundreds of dollars per month, and your provider can walk you through specifics based on your labs.
A Reasonable Approach
Many men find success combining evidence-based lifestyle habits, like resistance training, adequate sleep, and a nutrient-dense diet, with medical treatment when bloodwork confirms a genuine deficiency. Supplements like cordyceps can be a reasonable addition to that foundation, but they shouldn’t be relied on as a primary strategy if your levels are clinically low.
Take the Next Step
If you suspect your testosterone is genuinely low rather than just sluggish, book an appointment for bloodwork and a personalized plan.
FAQs
Does cordyceps actually raise testosterone in humans?
The evidence is currently strongest in cell and animal studies. Direct human research on testosterone specifically remains limited.
Is the cordyceps in supplements the same as the one in fiction?
The general fungus genus is real, but the dramatic fictional premise of human infection has no scientific basis. Supplement cordyceps is cultivated safely for human use.
How long does cordyceps take to potentially affect hormones?
Most studies, where effects were observed, used several weeks of consistent use, though human data on timing remains limited.
Can cordyceps replace TRT?
No, cordyceps has not been shown to meaningfully correct clinically diagnosed low testosterone the way medical treatment can.
Is cordyceps safe to take daily?
Generally considered safe for most healthy adults in studied doses, though you should consult a doctor before adding any new supplement.
What other benefits does cordyceps have besides testosterone?
Research points most consistently to athletic performance support and antioxidant properties, with testosterone effects being more preliminary.
