Everything about Total T (Total Testosteron)

What is Total T?

Total T stands for total testosterone. It is used to diagnose the cause of masculine physical features, infertility, or Polycystic Ovary Syndrom (PCOS). 1 in 10 women suffers from PCOS. Having a high T value, in combination with having high AMH and low LH, gives you about 75% certainty that you suffer from PCOS (reference 1).

Why is testosterone test needed?

Testosterone is needed for hormonal balance and to help women's bodies to function normally. If your body is producing too much testosterone, you may have more body hair than average, have abnormal or no menstrual periods, or be infertile. A testosterone test, in conjunction with measuring other hormone levels, can you understand what is causing your symptoms.

When can I test Total T?

You can take the testosterone test in any day of your cycle. However, as we are also testing other hormones that are to be collected on the 3rd full day of your period, we recommend to do it all at the same time.

The first day of your period is the first day you get a full flow by 5 PM. For example, if your period started on Monday but you only have spotting and your full flow started after 5:30 PM, then Tuesday will be your first day of period and Thursday is the 3rd day - i.e., the day you should prick your finger and collect your blood.

I am on birth control, can I test my Testosterone?

No. Birth controls could reduce testosterone level by 61% (reference 2). As a result, we do not test Total T if you are on birth controls.

I have a low/high level of testosterone, what does that mean?

Women can have health problems because of low or high levels of testosterone. Women with high levels of testosterone may have Polycystic Ovary Syndrome (PCOS), especially when combined with high AMH and low LH. High level of testosterone may include symptoms such as irregular menstrual period, low sex drive, vaginal dryness, fertility problems, etc.

If your results deviates from the reference point, we recommend you to share them with your GP. Typically the GP will order additional tests such as free testosterone. You can also set up a call with Grip's doctor via hello@gripfertility.com.
