Penile discharge

Overview

Penile discharge is any fluid other than urine or semen that comes from the tip of the penis. It can be a sign of an infection or other medical condition.

Penile discharge is a fairly common reason for men to visit their GP or a sexual health clinic, especially among sexually active individuals.

Anyone with a penis can develop penile discharge, including children and older adults. It is most common in sexually active people, particularly those under 25.

Symptoms

Common symptoms

• White, yellow, green, or clear fluid dripping from the penis
• Pain, burning, or stinging when passing urine
• Itching, redness, or swelling around the head of the penis
• Soreness or discomfort in the genital area

Symptoms in children

• Redness or swelling around the opening of the penis
• Crying or signs of pain when urinating
• Unusual discharge on underwear

Symptoms in older adults

• Discharge that may be thick or bloody
• Difficulty or pain when urinating
• Fever or chills

Causes

Main causes

• Sexually transmitted infections (STIs) like chlamydia, gonorrhoea, or trichomoniasis
• Non-STI infections such as a urinary tract infection (UTI) or balanitis (inflammation of the head of the penis)
• Irritation from soaps, detergents, or latex condoms
• Injury or trauma to the penis

Risk factors

• Having unprotected sex (without a condom)
• Having multiple sexual partners
• A recent history of an STI
• Poor hygiene or foreskin problems
• A weakened immune system

When to see a doctor

See a doctor urgently if:

• You have discharge plus severe pain, fever, or cannot urinate
• You see blood in your urine or discharge

Book a routine appointment if:

• Any abnormal discharge that lasts more than a day
• You have had unprotected sex and are worried about an STI
• Your sexual partner has been diagnosed with an STI

Diagnosis

A doctor or nurse will ask about your symptoms and sexual history, and examine your penis. They may also take a sample of the discharge for testing.

Tests that may be done

• Urine test to check for infection
• Swab of the discharge (like a cotton bud) to test for bacteria
• Blood tests if an STI like syphilis or HIV is suspected

What to expect at your appointment

The healthcare provider will likely ask you questions about your sexual activity, partners, and any past infections. This information is confidential and helps choose the right treatment. You may be offered a free test at a sexual health clinic.

Treatment

Treatment depends on the cause. There are effective medicines for most infections, and early treatment can stop the infection spreading and prevent complications.

Self-care at home

• Keep the genital area clean and dry
• Avoid using soaps, shower gels, or products that may irritate
• Do not have sex (including oral or anal) until you have completed treatment and been told you are clear
• Wear loose-fitting, cotton underwear

Medical treatments

Antibiotics are the main treatment for bacterial causes like chlamydia and gonorrhoea. Your doctor will prescribe a course of tablets or a single injection. For infections like trichomoniasis, anti-parasitic medication is used. If the cause is not an infection, treatment will focus on the underlying issue, such as avoiding irritants or treating skin conditions.

When is surgery considered?

Surgery is not usually needed for penile discharge. In rare cases, if a tight foreskin (phimosis) causes repeated infections, a circumcision may be discussed as a long-term option.

Living with this condition

Follow your treatment plan exactly as given. If you are prescribed antibiotics, finish the whole course even if you feel better. Avoid any sexual activity until your follow-up test confirms the infection is gone.

Lifestyle tips

• Use condoms every time you have sex to reduce the risk of passing or catching infections
• Tell your sexual partner(s) so they can also be tested and treated
• Practice good hygiene by washing the penis gently with warm water

Diet and exercise

A balanced diet and staying active help your immune system stay strong, but there is no specific diet for penile discharge. Drink plenty of water to keep urine less concentrated.

Mental health and emotional wellbeing

Penile discharge can cause embarrassment, anxiety, or worry about sexual health. These feelings are normal. Talking to a healthcare provider or a trusted person can help. Remember that most causes are treatable, and you are not alone.

Prevention

Many cases of penile discharge can be prevented by practising safer sex and good hygiene.

Vaccines

The HPV vaccine can prevent some infections linked to genital warts and certain cancers, but it does not prevent all causes of discharge. Talk to your healthcare provider about vaccination.

Screening programmes

Regular STI screening (tests) is recommended for people who are sexually active, especially if you have new or multiple partners. Many clinics offer free, confidential testing.

Complications

If left untreated

• The infection can spread to the testicles (epididymitis) causing pain and swelling
• In men, untreated STIs can lead to infertility (difficulty fathering a child)
• An infection can be passed to sexual partners, which may cause pelvic inflammatory disease in women
• Rarely, a serious bacterial infection can enter the bloodstream (sepsis)

Long-term outlook

With prompt diagnosis and treatment, the outlook for penile discharge is excellent. Most infections clear up completely with a short course of medication. Taking steps to prevent future infections can help you stay healthy and protect your partners.
