Bird Flu Is Back in the Headlines – Should Men Be Concerned?
Bird flu (H5N1) is making waves in 2025, with cases spreading among dairy cows, poultry, and even humans. While the general risk of infection remains low, viruses like this can take a serious toll on your immune system—and your hormones.
As a man, your testosterone levels play a critical role in how well your body fights off infections. If you’re already dealing with low testosterone (which affects up to 40% of men over 45), your immune defenses could be weaker than you think.
Here’s what you need to know about bird flu, how it could impact your hormones and immune system, and what you can do to protect your health.

Bird Flu and Men’s Health: The Connection
Most men don’t think about their hormones when they hear about the flu, but the two are closely connected. Testosterone plays a major role in immune function, and when levels are low, the body has a harder time fighting off infections.
How Viruses Like Bird Flu Affect Testosterone
Viral infections increase inflammation, which can suppress testosterone production.
Fever and illness can temporarily lower testosterone, leading to fatigue, low energy, and decreased strength.
Men with low testosterone may have weaker immune responses, making it harder to recover from illnesses.
Men on TRT: What You Need to Know
If you’re already on testosterone replacement therapy (TRT), you may have a stronger immune response than men with untreated low T. However, illness can still disrupt hormone balance, which is why it’s important to keep your testosterone levels optimized.
How to Keep Your Testosterone Levels Strong and Your Immune System Ready
You can’t control viral outbreaks, but you can control how well your body fights off infections. Here’s how to naturally support your testosterone and immune system so you stay strong and resilient.
1. Prioritize Nutrient-Dense Foods
A diet rich in zinc, vitamin D, and healthy fats is essential for testosterone and immune function.
Best testosterone-boosting foods: Eggs, grass-fed beef, avocados, salmon
Immune-supporting foods: Citrus fruits, leafy greens, garlic, and nuts
⚡ Did you know? Men with low zinc levels have 30% lower testosterone levels than those with adequate intake.
2. Get Enough Sleep (7-9 Hours Per Night)
Testosterone production peaks at night, and studies show that men who sleep less than 5 hours per night have 15% lower T levels.
Aim for 7-9 hours of uninterrupted sleep to keep hormones balanced and immune function strong.
3. Train Smart – But Don’t Overtrain
Regular exercise boosts testosterone, but excessive cardio and overtraining can cause a dip in T levels.
Best workouts for testosterone: Heavy weightlifting (squats, deadlifts), HIIT training
Avoid too much endurance exercise, which can raise cortisol and reduce T production.
4. Manage Stress – It Kills Testosterone
Chronic stress increases cortisol, a hormone that directly lowers testosterone levels.
Practice stress management: Deep breathing, sauna use, or short walks in nature
Limit screen time and social media (excessive doom-scrolling raises cortisol levels)
5. Optimize Your Testosterone with Injections
Even with the right diet, sleep, and exercise, many men still experience testosterone decline due to age, lifestyle, or other health factors.
That’s where testosterone optimization therapy (TOT) and vitamin injections come in.
