Low testosterone, or low T, is one of the most common but least talked-about issues men face as they age. It doesn’t just affect sex drive—it impacts energy, mood, muscle tone, sleep, and even hair growth. If you’re in your 40s or beyond and not feeling like yourself, testosterone might be part of the picture.
Let’s break down what causes testosterone to drop and what you can do about it.
Natural Testosterone Decline With Age
Testosterone levels naturally start to decline around age 30. By the time men hit their 40s, it’s common to see a 1% drop per year. For some men, the symptoms are barely noticeable. For others, the changes hit harder and faster.
You might notice:
- Lower sex drive
- Trouble with erections
- Less morning energy
- Muscle loss despite exercise
- Weight gain, especially around the belly
- Mood changes like irritability or low motivation
- Thinning hair or dry skin
If those sound familiar, it’s worth getting your levels tested. These signs are not just “part of getting older.” They often signal a hormonal shift that’s worth correcting.
This kind of hormonal imbalance often overlaps with other symptoms like erectile dysfunction or fatigue, which is why it’s important to understand how men’s health is all connected.
Lifestyle and Environmental Triggers
Age isn’t the only reason testosterone drops. Daily habits and exposures can play a major role.
Stress
Chronic stress increases cortisol, a hormone that directly suppresses testosterone. If you’re constantly feeling burnt out, your body may be in hormone survival mode, not hormone optimization mode. That stress can also interfere with your sexual performance, as explained in our post on how stress affects men sexually.
Poor Sleep
Testosterone is produced during deep sleep. If you’re not getting quality rest, or you wake up frequently, you could be missing your body’s key production window.
Processed Foods and Nutrient Deficiencies
Diets high in refined carbs, seed oils, and sugar can throw off hormone production. Zinc, magnesium, and vitamin D are all essential for healthy testosterone levels—and most men aren’t getting enough.
Alcohol and Toxins
Heavy drinking lowers testosterone and can damage the glands responsible for producing it. On top of that, many plastics, pesticides, and chemicals in personal care products contain endocrine disruptors that mimic estrogen and interfere with hormone balance.

Underlying Medical Conditions
Low testosterone is sometimes a symptom of a deeper health issue, not the root problem. These conditions can suppress production or interfere with the body’s hormone signaling:
- Obesity: Fat cells convert testosterone into estrogen, reducing available T
- Type 2 Diabetes: Insulin resistance lowers testosterone output and contributes to erectile issues
- Sleep Apnea: Poor oxygen flow during sleep disrupts hormone cycles
- Thyroid Disorders: A slow thyroid can cause low T symptoms even with “normal” testosterone levels
Diabetes, in particular, can have a major impact on both testosterone and sexual function. If that’s something you’re dealing with, our blog on how diabetes affects sexual health and hormone balance may be helpful.
When to Get Tested
If you’re over 40 and dealing with low energy, mood changes, poor performance, or body changes that don’t match your lifestyle, it’s time to test. A simple blood panel can check both total and free testosterone, along with other hormones like SHBG, DHEA, and estradiol.
