Testosterone is a hormone (androgen) which is found in both sexes - male and female. It is produced in the pituitary gland within the brain, from which is travels through the blood to serve its various roles. Its primary role is to regulate male characteristics such as the development of male genitalia during puberty, the production of sperm, sex drive (libido), distribution of fat, regulation of muscle and bone mass, and stimulation of the hair follicles.
Later in a man's life, his testosterone levels will naturally decrease. This is commonly referred to as the male menopause (andropause) in the media.
When testosterone levels in males are low, a man can experience a range of symptoms, including:
What happens when a man’s testosterone is low?
Low levels of testosterone in the blood can cause a number of physical and psychological symptoms. Effects include:
- Decreased libido
- A reduction (or absence) in morning/night-time erections
- Erectile dysfunction
- Decreased body hair
- Gynaecomastia
- Reduction in muscle mass and strength
- Fatigue
- Sleep disturbances
- Mood changes (e.g depression, irritability, anxiety)
- Poor concentration and memory
To test your testosterone levels, you may need to conduct a home test. It is as simple as a finger-prick test. You can either have a kit sent to you or we can deliver it to your home. Our doctors will contact your about the results and next steps after receiving them.
Total testosterone: This is the total amount of testosterone found in the blood. Some of it is attached to proteins, such as Sex-Hormone Binding Globulin (SHBG) or Albumin, which transport it around your body. Low testosterone can be defined as <15nmol/L
Free testosterone: This is the testosterone which is not attached to any proteins so it’s free to be used by the body’s cells. When a cell binds to free testosterone its functionality is enabled, so the more you have of it, the better. Low free testosterone is defined as<0.225nmol/L
Sex hormone-binding globulin (SHBG): This protein is produced in the liver and regulates hormone levels by binding to sex hormones, including testosterone. When your SHBG levels are high, your body has less free testosterone available to be used by the body’s cells.
Albumin: Another protein produced in the liver which binds to testosterone, inhibiting its ability to be used by the body’s cells.

What is a normal testosterone level for my age?
A normal testosterone level for adult men is around 8.7–29 nmol/L (250–836 ng/dL). Most UK laboratories will use reference intervals similar to this. These values don’t take your symptoms, baseline levels, or age-related decline into account. But your doctor will consider this when interpreting your levels. If your testosterone levels are less than 12 nmol/L and you have symptoms, you may benefit from testosterone replacement therapy (TRT).
A 2022 study looked at testosterone levels of 1,486 men between the ages of 20 and 44 [6]. To calculate the normal testosterone level for each age bracket, they took the middle third and labelled these as normal results (according to the American Urological Association’s definition of normal testosterone):
| Age | Testosterone (nmol/L) | Testosterone (ng/dL) |
| 20–24 | 14.2–19.3 | 409–558 |
| 25–30 | 14.3–19.9 | 413–575 |
| 30–34 | 12.4–17.3 | 359–498 |
| 35–40 | 12.2–16.5 | 352–478 |
| 40–44 | 12.1–16.4 | 350–473 |
