What Is The Normal Size of Testicles

We often worry about our physical appearance and without a doubt the way our sex organs look can make us feel less or more confident in the bedroom. Whilst penis size seems to be very important for many men, testicle size often matters much less. However, if anything, it should be paid more attention, given that changes in testicle size can be an indication of a certain condition or abnormality. With this in mind, we at will provide a detailed explanation of what the normal size of testicles is and what conditions could cause them to change in size.

What is the Function of the Testicles?

Testicles play a very important role in a man's sexual health and are responsible for producing testosterone, the male hormone responsible for male physical characteristics and other factors such as levels of sexual desire. They are also responsible for producing sperm, essential for human reproduction.

It is therefore important that the testicles are healthy and in good condition, so that they can effectively carry out their sexual and reproductive function.

What is the normal size for testicles?

As with the penis, testicle size will vary throughout a man's life and will vary between men. However, there are some average measurements. The normal size for testicles is between 2 and 4 cm wide and between 4 and 8 cm long.

It is also normal for one testicle to be slightly larger than the other and for one to sit a little lower than the other. This is not a problem and should not be a cause for concern.

When Does the Size of Testicles Vary

Knowing the normal size of your testicles is important so that any change in size, which can indicate an underlying condition, can be easily picked up.

Some diseases can cause the size of the testicles to change, including:

  • Hydrocele or accumulation of water, also known as a water cyst.
  • Infections such as orchitis and epididymitis.
  • Testicular tumours.

If you notice an increase in one or both testicles, you should see your doctor for a routine checkup.
