Penis Odor and Possible Diseases

Penis Odor and Possible Diseases

Sometime men feel fishy odor down there. A foul or fishy odor is a big concern for any man as it might be a sign of an underlying condition. Besides the possibility of a health issue, if you smell bad down there, it can affect the quality of your physical and sexual relationships.

Penis odor can be controlled with proper hygiene and use of reasonably breathable undergarments. Men who are not circumcised can sometimes develop skin cells beneath their foreskin because of lack of proper hygiene and cleanliness that may lead to an infection, causing smelly penis. If you notice that smell is increasing or becoming stronger then this could be a cause of concern.

Primarily we believe that this problem arises due to the lack of proper hygiene habits but there are some other reasons as well besides poor hygiene. Here we will be discussing some of the primary causes of smelly penis.

Bacteria are usually found on the moist parts of your skin like groin due to natural sweat and oil secretions. This might also cause peculiar odor in the penis region.

  1. UTI (urinary tract infection):

Sometimes parts of urinary tract are infected due to colonization of a fungal, viral or bacterial agent (typically E. coli in urinary system). UTI can also causes smell in the penis or groin.  The primary causes of UTI includes sexual activities, prostatic hyperplasia, diabetes, stones in kidney, retaining urine, or use of indwelling urinary catheter.

Although Smegma is a natural lubricant that helps in keeping your penis moist, but when a large amount of Smegma builds up because of extreme sweating and poor hygiene condition then small white mass is created which is smelly due to overgrowth of bacteria.

Balanitis is the inflammation of the base or head of penis. Sometimes foreskin also swells and becomes inflamed (also known as balanoposthitis). It occurs due to the poor hygiene condition, unprotected sex, building up of Smegma if not treated on time, any infection, skin diseases like eczema, psoriasis etc, and due to use of perfumed soaps. The Balanitis makes your penis smelly.

It can be transmitted through your partner who already has this yeast infection. Other causes include poor hygiene specially when not circumcised. If not treated properly it will cause further severe infection.

  1. Non-gonococcal urethritis

NGU occurs if urethra gets inflamed. Urethra is a tube from bladder to penis and is responsible for exiting urine from your body. It is not caused by gonorrhea that’s why it is called non gonococcal urethritis. NGU is a result of bacteria and sometimes viruses that transmitted through sex. It makes your penis smelly and sore.

Smelly penis is very disgusting and embarrassing for any men. You can take some precautionary measures to prevent smelly penis

  • If you are not circumcised then try to pull the foreskin above your penis before passing urine. So that urine does not remain underneath and causing irritation.
  • Good hygiene is necessary. You should clean your penis and take bath regularly. Uncircumcised men should clean the foreskin to prevent infection.
  • Dry your penis after wash as moist penis also causes infection. But don’t rub it too hardly or with cloth.
  • Wear clean and comfortable cotton underwear. Your underwear should be loose so that air passes by and make your groin area able to breathe. It reduces the sweat and buildup of bacteria that causes infection and smell.
  • Public hair should be trim. If public hairs are not trimmed properly they hold bacteria, moisture and dirt that become the reason of infection.
  • Don’t sex with the person who is suffering with STI.
  • Wash your penis after sex.
  • Try to avoid lubricants.

Proper hygiene generally eliminate penis odor. But if you notice that odor is growing stronger with some other symptoms like itching, burning sensation when you pee, white chunks or pain then you should consult your doctor.
