What Do Testicles Do?

You know you've got something chillin' down between your legs that must have some sort of function, but what exactly do your testicles do? Sure, they spend most of their time hanging out, but they must have a purpose, right? Well, like most parts of your body, they do, indeed, serve an essential function or few. Besides serving as a down-below decoration piece, your testicles are responsible for producing the sperm that keeps the human population moving and shaking. They've got a big job to do, so let's take a moment to explore the tasks your testicles are charged with.

What's Another Word for Testicle?

"Testicle," of course, is the proper term for your boys. You might also know this set of body parts as gonads, balls, cojones, knackers, or nuts. In short, the words used for this body part often relate to their shape and size, which is characterized by two oval-shaped organs that produce sperm in men and other male mammals. Testicles, which generally come in pairs, are encompassed in a blanket of sensitive, slightly wrinkly skin called the scrotum. This entire package of parts is located behind the penis, where it has easy access to pump out the matter that makes babies and keeps the human (or another mammal) race multiplying.

In slang terms, you might here testicles referred to as family jewels, bollocks, or cullions. For centuries, the male genitalia has incurred dozens of names that vary across countries and regions. What someone in the South calls their junk might be very different from the term a Californian would use. Think of it as the difference between "soda" and "pop," "hoagie" versus "hero sandwich," "take-out food" as opposed to "to-go food;" the phrases mean the same thing, but depending on where you are and who's doing the talking, the words for testicles might vary. Trust us—there's no shortage of synonyms for this part of the male anatomy! 

5 Fun Facts About Testicles

Before we give you the medical ins and outs of your lower region, let's talk about some fun tidbits you might not otherwise know about testicles.

  1. Testicles are five degrees colder than the rest of the body. The testicles need to preserve their sperms' ability to swim, and that means they need to regulate the temperature of the cells they're tasked to protect. The scrotum is about 93.4 degrees Fahrenheit, while the rest of the body is generally about 98.6 degrees.
  2. Male right whales have testicles that weigh around 1.1 tons and have the ability to produce one gallon of semen. 
  3. The word "avocado" derives from the Aztecan word for "testicle." The same can be said for the Greek word "orchid."
  4. Testicles have the most diverse proteins of any organ. There are almost 1,000 unique proteins expressed in a single splooge of sperm. The human brain only has 318 unique proteins.
  5. Each sperm contains 37.5 megabytes of data that can create another human being if it finds itself in the right place at the right time.

What Do Testicles Do?

Testicles' main function is to make and store sperm. These parts also produce testosterone, the male hormone that's responsible for regulating:

  • Sex drive (also known as your libido)
  • Bone mass
  • Fat distribution
  • Muscle mass
  • Strength
  • Production of red blood cells
  • Production of sperm

what do testicles do?

The testicles start working their magic during puberty. That's when boys will start to experience wet dreams, erections, and all the things associated with manhood and their manly parts. After puberty is done playing its role in a guy's life, the testicles carry on, producing millions of tiny sperm each and every day. The sperm mixes with a white, milky substance that's called semen. Together, the semen and sperm unite to when a man ejaculates, with the biological goal of creating another human when the substance is transmitted from a man into a woman. Guys become fertile during puberty, which is generally somewhere between 11 and 17 years of age. At that time, and any time thereafter (barring any medical obstacles), they can get women pregnant. 

The size of testicles varies from guy to guy. They're usually about two to three inches long and around one inch in width. They grow during puberty, and the scrotum, which holds the testicles, darkens during that time period, too. It's at this time that young men will begin to experience hair in their nether regions. Some guys like to keep it that way, while other guys prefer to manscape their man parts as they get older. We'll talk more about proper manscaping techniques in just a few moments. 

When Do Testicles Appear?

Testicles usually appear ("drop" or "descend") by the time a baby boy is about nine months old. It's not uncommon for newborn males to have undescended testicles—that is to say, the testicles are often still up inside babies' bodies when they're born, especially if they're born prematurely. Sometimes, a muscle reflex causes the scrotum to be pulled up inside the body after the testicles have descended. This condition is called retractile testes. Usually, the testicles will re-descend on their own without requiring surgery. There are times when testicles don't descend into the scrotum on their own; in these cases, surgery is likely required, as undescended testicles can be prone to testicular cancer and other problems, such as decreased sperm production and minimized fertility.

Can One Ball Be Bigger Than the Other?

Since we're all humans, the short answer to this question is "Absolutely!" Very rarely are two parts of the human body exactly symmetrical. Take a long look at your eyes and ears in the mirror, for example. You'll probably notice that one is a little higher than the other, or maybe one eye is a little more rounded than the other. This same thing happens with your testicles. Just as a woman might have one breast larger than the other, you can easily have one testicle that got a few more cells than his right-hand man. 

Interestingly, the right testicle is usually the larger one, if both aren't the same size, according to WebMD. Additionally, the left testicle has been known to hang lower than the one on the right. The difference in size is generally of no concern, assuming your nuts have always been sized the way they are. You would, however, want to seek medical input if you've suddenly noticed your testicles are changing their size and shape long after you've finished going through puberty. 

If you do notice a change in the size and shape of your testicles suddenly, there are several reasons this could be occurring, including:

  • Epididymitis. This condition occurs when the epididymis (a duct behind the testes) becomes inflamed and/or infected. It's often caused by the introduction of a sexually transmitted infection (STI) such as chlamydia.
  • Orchitis. This condition is also related to inflammation and infection. It may occur after a man catches the mumps virus. This condition can damage the testicles, so a medical doctor should be seen right away if you suspect this is the cause of your lower-half discomfort.
  • Epididymal cyst. Sometimes, excess fluid can build up in the epididymis, creating a thin sac filled with fluid. They're usually harmless and don't cause pain; additionally, they typically go away on their own; however, if they're causing discomfort, surgical procedures can remedy the situation.

The Truth About Scrotum Shrinkage

Shrinkage is a real thing. While it may be more obvious with your main male part, your testicles also take to cover when they're cold. This is because your testicles naturally want to create as much sperm and spread as much wealth to the world as possible. However, in order to create an adequate amount of sperm, your balls need to be kept at just the right temperature. When they get cold, your body and brain work together to protect this precious cargo, sending a message to the scrotum to shrivel up so it can preserve heat. 

There are other reasons your scrotum may begin to shrink, some of which could be of concern, while others are simply a part of life. Testicular atrophy—or the condition by which the testes get smaller due to a loss of sperm- and testosterone-producing cells—may occur at different stages of men's lives. The following are a few causes that could lead to testicular atrophy:

  • Age
  • Testicular cancer
  • Orchitis (see above)
  • Diseases
  • Excessive alcohol consumption
  • Hormone imbalances
  • Testicular torsion
  • Varicocele

Again, if you notice a change in size and structure of your scrotum, whether your testicles seem to be shrinking or expanding, it's imperative to seek the assistance of a medical professional as soon as possible. Even if nothing's wrong with your body, you'll sleep better knowing for sure that your nether regions are just taking to a natural part of their processes.

The Problem with Pain in Your Pants

Your testicles should never hurt, barring any bad bicycle incidents that might've put you in a compromising position. If you do have a pain in your pants, it could be problematic. If your testicles hurt, the pain could be anything from something simple, such as a maneuver you shouldn't have made in bed, all the way to something severe, like a hernia, kidney stones, or cancer. There are times when testicles can become twisted, in which case the blood flow is cut off, causing severe pain and sometimes tissue damage. This condition is known as testicular torsion. If this situation happens for more than a few hours, it can cause permanent damage to the testicles and may require the damaged testicle to be removed. 

Other causes for testicular pain include (but are not limited to) the following possible conditions:

  • Gangrene
  • Diabetic neuropathy
  • Hydrocele
  • Spermatocele

If you're experiencing pain in your testicles, or if you feel a lump on your scrotum, consult your doctor right away. The aforementioned conditions may also present with symptoms such as fevers, redness, tenderness, nausea, vomiting, or swelling.

Tips for Healthy Testes

If you want to ensure your boys have a strong and healthy life, you need to cater to their needs. Follow the following tips to keep your body feeling its best, even below the waistline:

Perform monthly testicular self-exams

Check for lumps or swollen, tender areas by rolling each testicle around in your fingers. Over time, you'll get to know your body's nuances, and you'll be able to identify when something is new or doesn't feel right.

Bathe regularly

Thoroughly clean your genital area each day using a pH-balanced body wash that's specifically formulated for your special parts. It's important to use a cleanser that's pH balanced because it ensures your skin's natural barrier will be protected from losing the natural moisture it needs to stay healthy. 

Wear loose, comfortable clothing

Your boys have a pretty confined space in which to dwell, so don't make it even more uncomfortable for them by putting them in cramped pants and underwear that doesn't do them justice. Instead, opt for anti-chafing boxers that are designed to keep them in place while giving them a little breathing room. The same goes for jeans and pants—you want your testicles to have a little wiggle room, so to speak, so they can hang naturally from your body while regulating their own temperature throughout the day.

Protect yourself during intercourse

The easiest way to protect your penis from unintended consequences is to button up when you're getting lively between the sheets. A condom can help prevent sexually transmitted diseases and infections, which could otherwise compromise the health and well-being of your testicles.
