Master the basics
Our Head of Medical, Dr Luke Pratsides, tells you what you need to know about testosterone.
Testosterone is a sex hormone that’s vital for men’s health. Produced in the testes, the hormone supports key male functions including sex drive, ability to get and maintain erections, fertility, muscle mass and mood.
Optimal levels of testosterone are different for each man but to ensure healthy bodily functions, you must have a certain level of the hormone. Lower levels of the hormone can, in some cases, impact libido, sexual function, energy and mood.
