Testosterone Levels In Men

Testosterone is a hormone that affects almost every aspect of a man’s physical and mental well-being, from muscle mass to mood. In this article, we’ll break down what testosterone is, how it changes over time, and what you can do if your levels are too low or too high.

Testosterone is a hormone produced mainly in the testes in men, although women also produce small amount in ovaries. In men, it’s responsible for primarily for muscle growth, bone strength, body hair, and sex drive.

It’s not solely responsible for physical traits, though. Testosterone can also influence energy levels, mood, and even sleep quality. In women, it plays a smaller but similarly important role, particularly with regards to bone strength and muscle mass.

As mentioned already, the effects of testosterone are wide-ranging. Physically, it helps build muscle, burn fat, maintain bone strength, and even boost the production of red blood cells. Mentally and emotionally, testosterone can impact mood and energy levels, which is why low testosterone is sometimes linked to issues such as depression, fatigue, and irritability.

Testosterone also plays a key role in sexual health. Low levels can cause issues such as reduced sex drive or erectile dysfunction. It’s also crucial for sperm production, making it a major factor in fertility. 

A simple Testosterone blood test offers a comprehensive analysis of the overall testosterone levels present in the bloodstream.

Hormones like Testosterone work together in complex ways to regulate biological function. A Male Hormone Blood Test analyses levels of key hormones, including Testosterone, to assess masculinity, energy, and fertility. 

For a more comprehensive review of male health, an Ultimate Healthy Man Blood Test provides an in-depth understanding of various facets of male well-being. Testing 45 different biomarkers, the test monitors testosterone, cholesterol, micronutrients, full blood count, Thyroid, liver and kidney function. 

Testosterone levels in men naturally start to decline once you hit your 30s, dropping about 1% per year. Some men notice a dip in energy, sex drive, and even muscle mass as they get older.

It’s not simply related to aging, however. Other factors such being overweight or having a chronic health can speed up this decline. If you’re noticing more pronounced symptoms, it could be worth exploring your testosterone levels.

Testosterone levels in men can vary from person to person.

It’s also worth noting that your testosterone levels in men fluctuate throughout the day. They’re usually highest in the morning and decline as the day goes on, which is why blood tests to measure testosterone are often done early in the day.

Generally, testosterone levels may look something like this:

Men By Age Range  (nmol/L):

• 11 to 15 <0.24–26.25
• 16 to 17 7.92–27.0
• 18 to 49 8.7–29.0
• 50+ 6.7–25.7

Common symptoms of low testosterone include:

• Low sex drive or erectile dysfunction
• Feeling tired all the time
• Loss of muscle mass and increase in body fat
• Mood swings, irritability, or depression
• Difficulty concentrating or issues with memory
• Thinning body hair
• Weaker bones, making fractures more likely

It’s worth noting that many of these symptoms are non-specific and can be due to numerous causes, but testosterone levels in men may still be worth considering.

Testosterone production follows a daily cycle that is closely tied to your sleep and wake pattern. Levels usually:

• Peak early in the morning, typically between 7 am and 11 am.
  
  

• Gradually fall through the afternoon.
  
  

• Reach their lowest point in the evening and overnight.
  
  

This rhythm is most noticeable in men under 45, where morning levels can be up to one-third higher than those measured in the afternoon. In older adults, the daily rise and fall becomes less pronounced because the body’s natural hormone rhythm flattens over time.

Disrupted sleep, shift work, or irregular routines can also affect this pattern. People who work night shifts, for example, may experience their “morning” testosterone peak at a different time of day, depending on their sleep schedule.

These natural changes mean that the time of your test can make a real difference in how your results are interpreted. At One Day Tests, we typically recommend morning testing, between 7 am and 11 am, to capture peak hormone levels and ensure consistency with NHS and endocrinology guidelines.

There are a several ways in which to boost testosterone levels in men.

1. Exercise, Especially Weight Training: 
   Regular exercise, particularly resistance training and high-intensity interval training (HIIT), has been shown to naturally boost testosterone. Staying active also helps keep body fat in check.
   
   
2. Eat a Balanced Diet: 
   Diet plays a huge role in your hormone levels. Focus on a diet rich in proteins, healthy fats, and essential nutrients like zinc and vitamin D, both of which are important for testosterone production. Steer clear of sugary and overly processed foods—they can adversely affect your hormone levels.
   
   
3. Reduce Stress: 
   High levels of stress cause your body to release cortisol, a hormone that actually lowers testosterone. Finding ways to manage stress, whether it’s through meditation, yoga, or simply taking time for yourself, can make a difference.
   
   
4. Get Enough Sleep: 
   Sleep is critical for testosterone production. Most of the hormone is released during deep sleep, so aim for 7-9 hours each night.
   
   
5. Maintain a Healthy Weight: 
   Carrying extra body fat, especially around your abdomen, has been linked to lower testosterone levels. Losing weight through a combination of healthy eating and regular exercise can help balance your hormone levels.
   
   
6. Testosterone Replacement Therapy (TRT): 
   If your levels are extremely low and lifestyle changes aren’t helping, your doctor might consider testosterone replacement therapy. This can come in the form of injections, patches, or gels that help bring your levels back to normal. However, TRT does come with potential risks, so it’s important to discuss it with your doctor before starting.
   
   
7. Supplements: 
   Certain herbal supplements may help boost testosterone. There is limited evidence on the effect of these though, so it is worth discussing these with a doctor.

A testosterone test is worth getting if you have symptoms that could suggest low testosterone.

Common symptoms include:

• Low libido
  
  

• Erectile dysfunction
  
  

• Ongoing fatigue or low energy
  
  

• Low mood or reduced motivation
  
  

• Loss of muscle mass
  
  

• Reduced body hair
  
  

These symptoms can have a real impact on daily life. However, they are also quite general and can overlap with many other conditions such as thyroid disorders, stress, or depression.

This is why testing is important. A blood test helps confirm whether low testosterone is the cause or rule it out altogether.

If you do not have symptoms, testing is usually not necessary. Many people have natural variations in testosterone levels without any health concerns.

You can check your testosterone levels yourself using a home blood test kit.

Instead of attending a clinic, you collect a small blood sample from your finger using a finger prick device. This sample is then sent to a laboratory for analysis. The results are not instant, as they rely on proper lab testing rather than self diagnosis.

Most home testing services return results within a few days, often within one to two days after the laboratory receives the sample. This makes it a quick and accessible option for people who want clarity about their hormone levels.

Testing your testosterone levels is usually a straightforward process and can often be completed within just a few days.

The first step is deciding whether you would prefer a home test or a clinic appointment. Home testing is popular because it allows you to collect your sample privately and conveniently without attending a clinic. Clinic testing may feel more reassuring for people who would rather have their blood sample taken by a healthcare professional.

If you choose a home testosterone test, the kit is posted directly to your address with everything needed to collect the sample safely. Most home testosterone tests use a finger prick blood sample. Before taking the sample, it is usually recommended that you warm your hands to improve blood flow. You then use a small lancet to prick your finger and collect blood into the sample tube provided.

Once the sample has been collected, it is packaged securely and posted back to the laboratory for analysis. Results are normally sent electronically within a few working days after the laboratory receives the sample.

If you choose clinic testing instead, a phlebotomist or nurse will take blood from a vein in your arm. This process only takes a few minutes and the sample is then sent to the laboratory for testing.

Both testing methods are designed to provide accurate laboratory analysed results, so the best option often comes down to personal preference and convenience.
