It is OK if your balls hang as some degree of sagging of your balls is normal, especially as you age.
However if you have excessive sagging of your balls and especially if you're not older you may want to have it checked out.
Testicles though do naturally sag to protect the sperm inside of them and keep the viable although excessive sagging can sometimes indicate a health issue but not always.
The reason why one ball hangs or one testicle hangs lower is due to anatomical differences and the need for your testicles or balls to be at a slightly cooler temperature for optimal sperm production.
Your left ball or left testicle often hangs slightly lower than your right ball or right testicle due to the way your spermatic cord and your blood vessels are arranged.
And in some cases, a varicocele also known as swollen veins in your scrotum can cause one testicle to hang lower than the other testicle but in most cases one ball or one testicle hanging lower than the other is normal.
Balls also known as your testicles also hang lower as you get older and is a normal part of aging.
As you age as a man, the skin, which includes the skin that covers your scrotum, loses collagen and becomes less elastic which can lead to wrinkles and sagging skin including the skin in your scrotal area.
Your scrotum and testicles are also already positioned away from your body and the combination of the less elastic skin and gravity can make the sagging more noticeable.
And your cremaster muscle reflex also controls how close your testicles sit in relation to your groin area which keep the testicles temperature consistent.
And as you get older and age, your skin loses elasticity which can cause saggy testicles and wrinkles.
Sagging testicles are often a normal part of aging and are not usually a cause for concern although in some cases, sagging testicles may be associated with other conditions such as varicoceles "swollen veins near your testicles" or hydroceles "fluid buildup around your testicles which can cause pain or discomfort.
Most men notice the balls or testicles sagging or hanging lower in their 60s and 70s.
Balls should not be hard but somewhat firm and smooth but not really hard or really squishy.
Your balls or testicles should also not have any bumps or lumps and should feel firm and smooth.
When you gently squeeze your balls or testicles the balls or testicles should feel like a smooth, firm egg.
It's also normal for one of your balls or testicles to be slightly larger or even hang a bit lower than the other and when you feel a soft, squishy structure at the top and back of your testicle it is the epididymis which is a tube that carries sperm and stores sperm.
If you feel any lumps or have swelling of your balls or testicles you should see a doctor promptly or if you notice any changes in shape or size or weight of the testicles you should see a doctor or if you have any pain or tenderness you should also see a doctor.
The signs of testicular cancer are a testicular lump which is often painless and a sensation of heaviness in your scrotum and a persistent ache in the testicle that is affected.
When your balls feel squishy it can be a result of an epididymal cyst "fluid filled sac, hydrocele "fluid buildup" or a varicocele "enlarged veins.
In rare cases the balls feeling squishy could be testicular torsion or testicular cancer.
If your balls continue to feel squishy you should see a doctor to rule out any possible serious conditions such as testicular torsion or testicular cancer.
Varicoceles are soft lumps which develop gradually above your testicle and one the left side of your scrotum.
Hydroceles are swellings in your scrotum caused by a build up of fluid.
When your balls disappear when you get hard it's due to a normal physiological response which is called the cremasteric reflex or cremaster reflex.
The cremasteric reflex or cremaster reflex is when your cremaster muscle contracts and pulls your testicle towards your body for protection and temperature regulation.
The reason why your balls or testicles go up when ejaculating is a result of involuntary contractions of your cremaster muscle.
The cremaster muscle is a smooth muscle which surrounds your testicles and pulls them up towards your body.
Your cremaster muscle is also a thin, pouch like muscle which covers your testes or testicles and connects your scrotum to your perineum.
When your cremaster muscle contracts it pulls your testicle up toward your body, which is a reflex known as your cremaster reflex.
The cremaster reflex helps to protect your testicles from injury and helps to regulate their temperature by moving the testicles closer to your body when it's cold or further away when it's warm.
And in some men the cremaster reflex can also be hyperactive and cause the testicles to retract more vigorously than they usually would which can occur especially during physical activity, sexual activity or emotional stress.
After ejaculating it takes on average of 2 months to 2.5 months or 74 days for sperm to build back up fully and mature after you release the previous batch of sperm during ejaculation.
Although you continuously produce sperm and can ejaculate the same day or soon after again it takes longer for full sperm buildup.
The entire process of sperm production which also called spermatogenesis takes between 64 to 72 days, from the time a germ cell begins developing to when it becomes a mature spermatozoon.
Sperm comes from the left and right testicles.
Both of your left and right testicles or testes are responsible for producing sperm and also the male sex hormone.
Your testicles are the primary organs of your male reproductive system that is responsible for producing sperm and they also produce and release testosterone which is a key hormone in male sexual function and development.
For optimal sperm production and over all male reproductive health, both testicles are required for producing sperm.
The sperm is also produced in your seminiferous tubules that are within your testicles and then move to your epididymis, where they mature and are stored.
And during sexual arousal, sperm are then released from your epididymis and travels through your vas deferens to be ejaculated.
And while the prostate does not produce sperm, the prostate does contribute to the production of semen which is the fluid which carries the sperm during ejaculation.
One part of your semen is produced in your prostate and together with your sperm cells from your testicles, the fluid from your seminal vesicle and the secretions are released by another pea sized gland below your prostate which is called the bulbourethral gland and the prostate fluid makes up your semen.
The prostate does many things which includes the production of seminal fluid.
The prostate is a gland which is located in a males reproductive system.
Your prostate produces a fluid which mixes with your sperm from your testicles to form semen.
This fluid also helps to nourish and protect your sperm and makes it easier for the sperm to travel and to fertilize an egg.
A males prostate also regulates ejaculation and contains muscles which contract during ejaculation which force your seminal fluid and sperm out of your urethra.
Your prostate also produces PSA also known as Prostate Specific Antigen which is a protein that plays a role in maintaining the health of your prostate gland.
And having elevated levels of PSA or prostate specific antigens can indicate prostate cancer or other potential prostate problems.
