Understanding Testosterone and Its Role in the Body
Testosterone is a vital hormone for both men and women, playing a key role in numerous bodily functions. In men, it regulates muscle mass, bone density, red blood cell production, and sexual health, including libido and sperm production. For women, testosterone supports bone strength, mood, and libido, although at much lower levels than in men.
Abnormal testosterone levels can affect your overall health; One Day Tests' Testosterone Blood Test offers a convenient and reliable way to monitor these levels. With fast, accurate results and a comprehensive health dashboard, you can track your testosterone levels and take proactive steps toward restoring balance, helping you feel your best. Early detection can prevent long-term issues and guide effective treatment options.
What is Testosterone?
Testosterone is a key hormone primarily produced in the testes in men and smaller amounts in the ovaries and adrenal glands in women. It plays a vital role in regulating muscle mass, bone density, and sexual function. In men, it is crucial for sperm production, libido, and maintaining secondary sexual characteristics like deeper voice and facial hair.
In women, testosterone contributes to bone health, mood regulation, and sex drive, although in much lower quantities compared to men.
Normal Testosterone Levels
Testosterone levels naturally vary by age and gender. In men, normal levels typically range from 8.64 - 29 nmol/L, while in women, normal levels are lower, usually between 0 - 1.67 nmol/L. These levels tend to peak during adolescence and early adulthood, gradually declining with age.
What Happens When Testosterone Is Too Low?
Low testosterone (hypogonadism) occurs when the body doesn't produce enough of the hormone. It can result from various causes, including ageing, medical conditions (e.g., diabetes or obesity), or issues with the testes or pituitary gland. Low testosterone may cause a variety of symptoms:
- Fatigue and low energy: Reduced testosterone can cause constant tiredness and a lack of motivation.
- Decreased libido and erectile dysfunction: In men, low testosterone often leads to a reduced sex drive and difficulty achieving erections.
- Mood changes: Individuals may experience depression, irritability, and mood swings.
- Muscle loss and increased body fat: Testosterone plays a critical role in maintaining muscle mass, and its decline may result in muscle wasting and weight gain, particularly around the abdomen.
- Weakened bone density: Long-term low testosterone can lead to osteoporosis, increasing the risk of fractures.
What Happens When Testosterone Is Too High?
Elevated testosterone is less common but can occur due to conditions such as testosterone replacement therapy (TRT), anabolic steroid use, or tumours that affect hormone production. Symptoms of high testosterone include:
- Aggression and irritability: Elevated levels may lead to increased anger, irritability, and aggressive behaviour.
- Acne and oily skin: High testosterone stimulates excessive oil production in the skin, leading to breakouts.
- Excessive hair growth or hair loss: In men, high testosterone may cause male-pattern baldness, while in women, it can lead to hirsutism (excessive facial or body hair).
- Increased muscle mass: High levels can lead to rapid muscle growth, but this is often associated with unnatural sources like steroids.
- Fertility issues: Paradoxically, extremely high testosterone levels, especially through supplementation, can reduce sperm production and lead to infertility in men.
What is a Normal Testosterone Level by Age?
Testosterone levels vary across age groups, peaking during adolescence and early adulthood before gradually declining with age. Generally, testosterone levels may look something like this:
Men (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
Women (nmol/L):
11 to 15 <0.24–0.96
16 to 17 0.41–1.50
18 to 49 0.29–1.67
50+ 0.1–1.42
If you're experiencing symptoms of low testosterone, it's important to check your levels and consult your doctor for advice. However, it's also natural for testosterone levels to decline gradually as you age, so mild reductions may not necessarily indicate a health issue. Regular monitoring can help you understand any changes and decide if further action is needed.
