Testosterone Blood Test

Testosterone is a male sex hormone that is vital for male performance. Healthy testosterone levels are important for maintaining energy levels, physical strength, muscle performance, bone density, sex drive, and even cognitive functions including memory and mood.

Testosterone levels peak when men are around 18 years old and then fall with age, typically falling by about 1% per year from your 30s or 40s. Some men are affected more than others. One in 4 men in their 30s have low testosterone, and about 40% of men over the age of 45 have low testosterone.

Low testosterone can lead to reduced physical performance, reduced muscle mass, fatigue, and decreased sexual desire. High levels are also unhealthy and carry health risks including heart disease and certain cancers.

Understanding your own personal testosterone levels and tracking those levels over time empowers you to work with healthcare practitioners to personalise lifestyle, nutrition, and fitness to optimise vitality, energy and performance. Equally, detecting potential hormone imbalances early can allow practitioners to intervene, promoting long-term well-being.
