¿How to check if you have low testosterone?
The only reliable way to confirm whether your testosterone levels are low is through a professional medical diagnosis.
Symptom evaluation
The specialist will review your medical history and any changes you have noticed in your body and well-being. Keeping a record of your symptoms and their progression can be very helpful for guiding the diagnosis.
Blood tests
Blood tests are the primary tool for measuring testosterone levels, including both total and free testosterone.
These tests are usually performed in the morning, when testosterone peaks between 7 a.m. and 10 a.m. It is also recommended to repeat the test on different days to confirm the results, as hormone levels can naturally fluctuate.
Additional tests
In some cases, the specialist may request additional tests for a more complete diagnosis, for example: measuring other hormones that influence testosterone production; evaluating potential chronic or metabolic conditions that may affect hormone production, such as diabetes, obesity, or thyroid disorders, imaging studies or more specific tests.
Never attempt self-diagnosis. Many symptoms of low testosterone may overlap with other health conditions or lifestyle factors, such as stress, lack of sleep, or a sedentary lifestyle.
Treatment and follow-up
Treatment for testosterone deficiency is tailored to each patient according to symptoms and needs. Options may include hormone therapy, lifestyle changes, and ongoing medical follow-up.
