Getting hit in the male private area causes severe, intense pain due to dense nerve endings, often leading to nausea, cramping, and pain radiating to the abdomen, but typically resolves with home care like ice and pain relievers, though severe symptoms like prolonged pain (over an hour), significant swelling, vomiting, or blood in urine/urine leakage require immediate medical attention as they could signal a testicular rupture or urethral injury needing emergency treatment like surgery.
Rest and protect an injured or sore area. Ice. Cold will reduce pain and swelling. Apply an ice or cold pack right away to reduce swelling.
It's comparable to getting kicked hard in the shin or knee. Lot's of pain at first, you may even fall over, and it fades away over time, but can persist for awhile afterwards.
In extreme cases, a blow can cause one or both of the testicles to rupture, potentially resulting in sterility. The clitoris is highly sensitive to impact as it has more nociceptive pain nerve endings than the testicles, making injuries especially painful.
It's a good idea to avoid strenuous activity for a while and take it easy for a few days. But get to a doctor right away if: The pain doesn't let up or you have extreme pain that lasts longer than 1 hour. You have swelling or bruising of the scrotum or a puncture of the scrotum or testicle.
Critical injuries
Specific symptoms of internal bleeding
For males, the most common sign of a problem is blood – even a drop – at the tip of the penis. Swelling and bruising of the penis, scrotum, and perineum may also occur, along with pain in that area.
Deep pain (collision dyspareunia): This is pain that occurs in deep penetration. It may feel worse in certain sexual positions. This type can happen due to conditions affecting your bladder or bowel, pelvic floor dysfunction, endometriosis or pelvic congestion syndrome.
Interestingly, there may also be gender differences in responses to some analgesics, including possible side effects. However, lab-based studies also find men demonstrate a higher pain threshold (the point at which you first detect pain) and higher tolerance to pain, compared to women.
A note from Cleveland Clinic
It's common to accidentally take a hit to your groin. Most of the time, it's minor and the pain goes away after a little while. A ruptured testicle isn't minor. The pain doesn't go away with rest or ice.
Testicular pain causes include sudden injury, inflammation, sexually transmitted infections or medical emergencies. It can cause a dull ache that affects one or both testicles or your scrotum. It can also cause swelling.
A healthy penis varies greatly in shape, size, and color but is generally free of pain, sores, warts, or unusual discharge, though some normal variations like visible veins, a slight curve, or small bumps (pearly penile papules) are common. Key signs of health include comfortable urination and sexual function, with changes in appearance or sensation often signaling a need for medical review.
The most sensitive part of the penis is the area around the frenulum, the skin flap on the underside of the penis just below the urethral meatus (where he urinates). There is a spinal cord pathway that connects there and rapidly sends signals to the ejaculation center of the spinal cord. Ejaculation is also hormonal.
The head of the penis can be pink, deep red, purple, bluish, or greyish in colour. All of these colours are normal and can change depending on the blood flow to the head of the penis at the time.
Testicular torsion is a condition that occurs when the testicles rotate, and the spermatic cord is twisted, which brings blood to the scrotum. The reduced blood flow leads to sudden and often severe pain and swelling in the testicles. The condition also leads to the darkening of the testicular skin.
Blood can build up under the skin of the penis (hematoma), and may become swollen and badly bruised.
The urethra is repaired surgically after all other injuries have healed or after 8 to 12 weeks (when inflammation has resolved). Rarely, urethral tears heal without surgery. Treatment helps to prevent some complications of urethral injuries. Complications that cannot be prevented are treated accordingly.
The two basic types of damage to the bladder by trauma are bruises and tears. Blunt injury (a bruise) is damage caused by blows to the bladder. Penetrating injury (a tear) is damage caused by something piercing through the bladder. Almost everyone who has a blunt injury to the bladder will see blood in the urine.
Male cystoscopy. Cystoscopy uses a thin, flexible tool with a light on the end, called a cystoscope. This allows a healthcare professional to see the inside of the urethra and bladder to diagnose conditions that affect the urinary tract.
In other cases, there is massive blood loss that is sudden and rapid, and it causes severe symptoms of internal bleeding. Even small internal hemorrhages can quickly become life-threatening and cause death within hours if they are not treated.
Volume and flow are two ways to tell if bleeding is life-threatening. Volume is the amount of blood present. Think about a soda can. Bleeding may be life-threatening when the amount of blood present is equal to about half of what a soda can contains.
Overt bleeding might show up as: Vomiting blood, which might be red or might be dark brown and look like coffee grounds. Black, tarry stool.
