Your testicles do many things for you that you may or may not know. They create the testosterone that fuels your masculinity. In addition, testosterone boosts your mood, energy, and is used to create the sperm that is contained within your testicles. You may have a lot of questions about your testicles, so this article will answer a couple of them.
#1 WHY YOUR TESTICLES ARE OUTSIDE OF YOUR BODY
If someone targets your testicles, you may wonder why they are not within your body if they are so precious and sensitive. Most answers would say that the testicles must be kept between two to three degrees cooler than the rest of your body to function as they should, but that is not the entire story. The University of Albany believes that this lower temperature is needed not just to ensure the testicles are properly working, but to ensure the sperm stays inside of the sacs.
As sperm has a very short lifespan after they become active, this lower temperature may support the life of sperm by keeping them from becoming active. This will ensure more are available when an ideal condition, such as a woman’s vagina, comes along. As many sperm are not good swimmers, only a few make it anywhere close to the egg. Often, sperm do not know which direction to go or are unable to make the swim.
#2 TINY TESTICLES
Human males have very small testicles compared to other animals. This may be due to the fact that, because we are mostly a monogamous species, men do not have a great deal of competition for women, so their testicles have not grown in order to intimidate other men. Across many other species, from chimps to ants, the males have larger testicles when the females mate with more than one male. Males may release more sperm if they have larger testicles.
#3 SEX ENLARGES YOUR TESTICLES
Just like the penis enlarges during arousal by filling with blood, the testicles also fill with blood during sexual relations. At this time, your testicles may grow by 50 percent or more. If you find that your testicles are growing or shrinking without any stimulation you should go see your physician and notify him/her of these differences.
#4 WRINKLES AND YOUR TESTICLES
While your testicles may look wrinkled, they are actually smooth. The dartos muscle is what gives your testicles their wrinkled look. Currently, there are surgeries available that can lift your testicles and alter the shape and size of your testicles. These procedures can remove hair, skin tags, and other blemishes.
#5 WHY DO YOUR TESTICLES MOVE?
You may experience small and large movements of your testicles. These small movements are caused by blood moving through the tiny arteries and veins of the scrotum. Larger movements may be related to many different reasons. As the testicles require certain temperatures for maximum production, they are equipped with muscles to ensure they stay at the best temperature. These muscles include the dartos and cremaster muscles. The dartos muscles are responsible for the wrinkled look of your scrotum, while the cremaster muscle lifts and lowers the scrotum and the testicles.
When you are engaging in sex, the cremaster muscles move your testicles closer to your body to support ejaculation. A fascinating experiment may involve watching the cremasteric reflex in action. When this reflex is stimulated, your testicles will respond like a turtle. The cremasteric reflect can be stimulated when your partner lightly strokes your inner thigh. After this, you can witness your testicles pull closer to your body to protect them from potential threats. When the threat is gone your cremasteric muscles relax and lower your testicles down.
#6 YOU CAN HAVE MORE THAN TWO
A rare condition called polyorchidism causes men to have more than two testicles. Many of these men have three, but the highest recorded number was five. Throughout history, there has been just 100 cases of polyorchidism and these cases have shown that, most often, the extra testicles are in the left sac. This condition is usually discovered at the age of 18. It is unclear whether polyorchidism affects fertility, but it may explain why some men are still fertile after undergoing a vasectomy.
#7 POTENTIAL CAUSES OF BUMPS OR LUMPS
While a bump or lump on your testicles can be very worrisome, most often these are not harmful. Common reasons for bumps and lumps include varicocele and epididymal cysts. Varicocele leads to larger than normal veins, similar to varicose veins. These may impact fertility and produce pain, but most are harmless, other than these two symptoms. Epididymal cysts are filled with fluid and grow at the back of the testicles. Rarely do they ever need any form of treatment. Cancer, on the other hand, can affect four of every 100 lumps that you may find in your testicles, but you should check with your doctor if you feel any abnormal bumps or lumps so he/she can check to make sure it is not cancerous.
#8 DECREASED FERTILITY
Drinking alcohol, smoking, and obesity are leading causes of decreased fertility. Smoking may choke the tiny veins in your testicles, reducing their functioning, and excessive alcohol usage can also damage your testicles. Obesity leads to lowered fertility because the excess fat signals the body to produce more estrogen. As sperm production is fueled by testosterone, increases in estrogen are certainly not what you want.
The effects of smoking and drinking can be reversed, so doing less of both, and eventually ceasing all together, is an excellent choice for the health of your sperm. Eating healthily, exercising a minimum of one and a half hours a week are great ways to boost your sperm production and concentration. Pertaining to healthily eating, adding antioxidants to your diet can be very beneficial.
These are just some of the facts about your testicles. Not only does ceasing drinking alcohol, smoking, and exercising more support your sperm, it will also support your overall quality of life.
