Testosterone Blood Test

It checks the level of testosterone in your blood. Your doctor uses it to diagnose conditions caused by too much or too little testosterone. That’s a hormone produced in a man’s testes.

During puberty, testosterone builds a man’s muscles, deepens his voice, puts hair on his chest, and makes his penis grow. Throughout a man’s life, the hormone also helps produce sperm and keep up his sex drive.

Women make testosterone too, but in smaller amounts. They produce it in their ovaries. It helps maintain hormone balance and regulates other body functions.

Why the Test is Performed?

In males, the testosterone test can help find the reason for sexual problems, like reduced sex drive or erectile dysfunction. If you’re having a hard time getting your partner pregnant, the test can tell if your blood testosterone level is low. It can also screen for problems with the hypothalamus or pituitary gland. This controls how much testosterone your body makes.

In females, this test can find the reason you’re missing periods, not having periods, or having a hard time getting pregnant. Doctors can also use it to diagnose polycystic ovary syndrome (PCOS). That’s a hormone problem that can cause irregular periods and make it hard to get pregnant. A testosterone test can also reveal if you might have a tumor in your ovaries that affects how much of the hormone your body produces.

Your doctor might order it if you have symptoms of low or high testosterone.
