Testosterone is the sex hormone produced by the testes in men. It doesn’t just concern men though – women also produce testosterone in their ovaries and adrenal glands but usually in smaller quantities.
Testosterone plays a key role in many essential body functions, such as sex drive (libido), energy levels, healthy bones, muscle mass, strength, and mood. It also controls sperm production, so changes in this hormone can affect your fertility.
This test is for you (men and women) if:
- you want to find out whether low testosterone levels are causing your symptoms such as low sex drive, low energy levels, or low muscle mass
- you want to check whether your testosterone levels are within the normal range
- see whether your testosterone levels are decreasing with age
- guide your exercise and dietary choices to increase your testosterone levels naturally
- monitor your testosterone levels whilst taking hormone replacement, such as testosterone replacement therapy (TRT)
- investigate whether your testosterone levels are too high
Testosterone in men:
Testosterone is an essential hormone for men because it maintains male sex drive (libido), sperm production, fertility, and mood. Testosterone levels sometimes fall gradually in men from around the age of 30 years. For many men, this gradual fall in testosterone causes no symptoms. For others, it can negatively affect mood, motivation, and sex drive. Low testosterone can even cause a decrease in muscle mass in the body alongside increased fat mass and gynecomastia (breast tissue development). This age-related decline in testosterone is sometimes called the ‘male menopause’, ‘manopause’, or andropause. Some younger man can also experience low testosterone levels, this is called hypogonadism.
Testosterone in women:
Women can experience low levels of testosterone in menopause which can lead to symptoms such as poor bone health, vaginal dryness, and reduced sex drive. Women can also experience high testosterone levels with health conditions such as Polycystic Ovary Syndrome (PCOS). Women may be interested to take the Polycystic Ovary Syndrome (PCOS) Blood Test, which is specially designed to help women find out whether their hormone levels could be contributing to symptoms of PCOS.
