Testosterone is a sex hormone that plays an important role in the body.

In men, it regulates sex drive, bone mass, fat distribution, muscle mass, strength, production of red blood cells and sperm.

Elevated testosterone levels in women can lead to a range of symptoms, including irregular or missed periods, increased facial and body hair, blood sugar imbalances, thinning hair and persistent acne.

High testosterone levels can also affect fertility, making it more difficult to conceive. Testosterone levels are monitored as part of a comprehensive fertility evaluation to identify potential hormonal imbalances and help guide fertility treatment decisions.
