What is TRT monitoring?

Testosterone replacement therapy (TRT) is a medical treatment for conditions which result in low testosterone levels. Testosterone is a steroid hormone that plays a key role in the development of the male reproductive system, muscle mass and body hair. Testosterone levels decline with age in males, a process known as andropause, resulting in physiological changes including reduced muscle strength and bone density. Symptoms of low testosterone include reduced bone and muscle mass and low sex drive. Monitoring of TRT is important, as negative side-effects of the treatment include skin conditions, low sperm count, increased risk of blood clots, heart attack and stroke.

Why take the test?

This test measures the level of testosterone and related hormones oestradiol and prolactin. It is useful to monitor hormone balance to adjust and optimise the dosage of testosterone replacement therapy (TRT).
