Testosterone Free
Understanding Testosterone Free
What is Testosterone Free?
This test measures the amount of free testosterone in your blood. Testosterone is the main sex hormone in males. It controls sex drive, maintains muscle mass, and helps in the production of sperm. Women also have testosterone in their bodies, but in much smaller amounts.
A testosterone test may be used to diagnose conditions such as decreased sex drive, infertility, erectile dysfunction in men, and irregular menstrual periods in women.
The levels are highest during early morning and lowest in the evening. Low testosterone levels can also lead to low sperm count, low sex drive, and hair loss. Men who are diagnosed with low testosterone levels may benefit from testosterone supplements.
