Hair on Testicular for Mens
Testicles have 2 main functions:
- They make male hormones, like testosterone.
- They make sperm, the male cells needed to fertilize a female’s egg to start a pregnancy.
Sperm cells form inside the testicle and are then stored in the epididymis (EP-ih-DID-uh-mus), a small coiled tube behind each testicle, where they mature.
When a man ejaculates ( has an orgasm), sperm cells travel from the epididymis through the vas deferens (vass DEF-er-ens) to the seminal vesicles (SIM-uh-nul VES-ih-kuls), where they mix with fluids made by the vesicles, the prostate gland, and other glands to form semen. This fluid then travels through the urethra (yoo-REE-thruh) and out through the penis.
Testicular cancer facts
- Males of any age can develop testicular cancer, including infants and elderly men.
- About half of all cases of testicular cancer are in men between the ages of 20 and 34.
- Testicular cancer is not common; a man’s lifetime chance of getting it is about 1 in 263. The risk of dying from this cancer is about 1 in 5, 000.
- Testicular cancer can be treated and usually cured, especially when it’s found early – when it’s small and hasn’t spread.
Symptoms of testicular cancer
You can’t be sure you have testicular cancer from just symptoms, so it’s important to see a health care provider about any testicular symptoms that concern you. Don’t wait.
- The most common symptom of testicular cancer is a painless lump on or in a testicle.
- Sometimes the testicle may become swollen or larger, without a lump. (It’s normal for one testicle to be slightly larger than the other, and for one to hang lower than the other.)
- Some testicular tumors might cause pain, but most of the time they don’t. Men with testicular cancer may also have a heavy or aching feeling in the lower belly or scrotum.
- Breast growth or soreness: Rarely, testicular cancers can cause men’s breasts to grow or become sore. This is because certain types of testicular cancer can make high levels of hormones that affect the breasts. Some men might also notice a loss of sexual desire.
- Signs of early puberty in boys: Some testicular cancers make male sex hormones. This may not cause any specific symptoms in men, but in boys it can cause signs of puberty, such as a deepening of the voice and the growth of facial and body hair, at an early age.
Symptoms of testicular cancer that has spread
If testicular cancer is not found early, it can spread to other parts of the body. Even when testicular cancer has spread, there may still be no symptoms. But some men might have some of the following:
- Low back pain from cancer that has spread to the lymph nodes in back of the belly. (Lymph nodes are bean-sized collections of immune cells.)
- Shortness of breath, chest pain, or a cough (even coughing up blood) from cancer spread in the lungs.
- Belly pain, either from enlarged lymph nodes, or because the cancer has spread to the liver.
- Headaches or confusion from cancer spread to the brain.
Non-cancer causes of testicular or scrotal symptoms
Problems other than cancer can also cause symptoms. Because it’s hard to figure out the cause based on symptoms alone, it’s important to have any testicular or scrotal change checked by a health care provider.
Some of the conditions that can cause a testicle lump, swelling, and/or pain include:
- Torsion of the testicle
- Epididymal cyst/spermatocele
- Inguinal hernia
- Kidney stones
Torsion of the testicle
In testicular torsion (TOR-shun), one of the testicles gets twisted inside the scrotum. This cuts off the blood supply to the testicle, epididymis, and other structures, leading to sudden, severe pain in the scrotum along with swelling and redness. It can also cause belly pain or nausea and vomiting.
Testicular torsion occurs most often in teen boys, but may occur later in life. It’s often diagnosed using ultrasound of the testicle/scrotum. Torsion is a medical emergency that needs to be treated right away. Surgery is needed to untwist the testicle, which restores the blood supply. If the torsion isn’t treated within several hours, the testicle can die and will have to be removed.
Physical injury to the scrotum or testicle can cause pain right way, or it may cause slowly worsening pain and swelling later on as the scrotum fills with blood. (This is known as a hematocele [hee-MAT-oh-seel].) Sometimes treatment may be needed to stop the bleeding, but the problem may get better on its own.
A testicular injury can be very painful, but it does not cause cancer.
Infections in the scrotal area are usually caused by bacteria or viruses.
Epididymitis (EP-ih-did-ih-MY-tis) is inflammation of the epididymis, the coiled tube next to each testicle that stores sperm. This can be caused by a sexually transmitted infection, but it can also be caused by other types of infection. Epididymitis can cause:
- Pain and swelling on one side of the scrotum. The pain tends to come on slowly, and it may spread to the side or back.
- Pain when passing urine
- Milky discharge from the penis
If the infection is caused by bacteria, antibiotics often will make the symptoms go away completely. But if these problems continue after you’ve taken antibiotics, you need to go back to the health care provider.
Orchitis (or-KIE-tis) happens when the testicle(s) becomes inflamed. It can cause painful swelling in one or both testicles. It also can impair fertility (make it harder to get a woman pregnant).
Orchitis can be caused by bacteria, including those that cause sexually transmitted infections and epididymitis. In fact, epididymitis and orchitis can happen at the same time. The mumps virus can also cause orchitis.
Sometimes a testicle can feel enlarged because fluid has collected around it. This is called a hydrocele (HI-dro-seel). It’s usually painless unless it grows too large. Sometimes the pain can spread to the lower belly or back. Hydroceles can have many causes. They’re usually harmless and rarely need to be treated. Hydroceles are often diagnosed with an ultrasound exam of the testicle and scrotum.
In varicocele (VAR-ih-ko-seel), the veins within the scrotum get very large (dilate). This can cause swelling and lumpiness around the testicle. It has been described as the scrotum feeling like a “bag of worms.” It’s usually painless, but it may cause a feeling of heaviness in the scrotum. Varicoceles can be diagnosed by a physical exam or with an ultrasound exam of the testicle and scrotum. They do not usually need to be treated.
An epididymal cyst (EP-ih-DID-ih-mul cist) may also be called a spermatocele (spur-MAT-oh-seel). It’s a fluid-filled sac much like a hydrocele, but the fluid inside contains sperm cells. It’s usually a small, painless lump in the scrotum that’s not connected to the testicle. These cysts are very common, and rarely need to be treated. They are often diagnosed with an ultrasound exam of the testicle and scrotum.
An inguinal hernia (ING-gwin-uhl her-NEE-uh) is in the groin. These hernias are caused by defects or weak spots in the muscles of the lower belly (the abdominal wall), which allow structures in the belly, such as fatty tissues and/or a loop of intestine, to go into the scrotum. There may be a slight lump or bulge in the groin or scrotum. The lump may be easier to see or feel when standing up. It’s sometimes painful, especially when bending over, lifting something heavy, coughing, or straining to pass urine or have a bowel movement.
