Are you less interested in sex than usual? Is your ability to have sex not as strong as it used to be? If so, you might be wondering if you have low testosterone, called low T. You might also be wondering what you can do to take control of the situation. Here are six steps you can take to verify if you, in fact, have low T, and the best available strategies to reverse it. Step 1: Learn the Basics Testosterone is the male hormone. It's responsible for the changes that take place during puberty. These include the deepening of your voice, the increase in your muscle size, and the growth of facial and body hair. The facts: Testosterone is made in your testicles. Testosterone increases your sex drive. Testosterone starts a natural decline in all men after age 30. By the time your reach age 60, there's a 20% chance your testosterone will be low.

A simple early morning blood test can tell if your symptoms are truly from low testosterone. Your level of testosterone is highest in the morning. It is measured in nanograms per deciliter (ng/dl). If your testosterone level is lower than 300 ng/dl, you may have low T.

They can include breast enlargement, prostate growth, acne, and skin reactions.
