About Testosterone

Testosterone is one of the most important male hormones. It is responsible for your sex drive and influences sperm production and fertility. It also keeps your heart, muscles and bones healthy.

What is TDS?

Low testosterone, also known as male hypogonadism or Testosterone Deficiency Syndrome, occurs when the body doesn’t produce enough of the hormone testosterone.

Testosterone levels between 300 ng/dL and 1000 ng/dL are generally considered within the normal range. It is only when levels fall below 300 ng/dL that they are considered to be low.

What causes low testosterone?

There are many reasons why testosterone levels can be low. It is normal for testosterone to decline with age, but it can also be affected by genetic or medical conditions. A signaling problem between the brain and the testes can cause the amount of testosterone being produced to drop. For example, the brain may send a signal to the testes in error that causes them to stop producing testosterone. Alternatively, insufficient testosterone production can be caused by a defect in the testes.
