Gonorrhea is one of the most common sexually transmitted infections (STIs) in Canada. It is caused by a bacterium called Neisseria gonorrhoeae and can affect both men and women of any age. Left untreated, gonorrhea can lead to serious health problems, including infertility. Understanding how it spreads, what symptoms to watch for, and how to get treated is an important step in protecting your sexual health.
What Is Gonorrhea?
Gonorrhea is a bacterial infection passed from person to person through sexual contact. It affects the genitals, rectum, and throat. According to Health Canada, gonorrhea rates have been rising in recent years, making awareness more important than ever.
The bacterium Neisseria gonorrhoeae survives only in the human body. It cannot live outside a human host for long. This means it spreads almost entirely through sexual activity, not through casual contact like hugging or sharing food.
Worldwide, millions of new cases are reported every year. However, many more cases go unreported because the infection often causes no obvious symptoms. This is why regular STI testing is a key part of sexual health care.
How Does Gonorrhea Spread?
Gonorrhea spreads through unprotected vaginal, anal, or oral sex with an infected person. It can also pass from a mother to her baby during childbirth. Using a condom correctly every time you have sex greatly reduces your risk.
Research shows that the risk of transmission is not equal for everyone. On average, a man has about a one-in-four chance of getting gonorrhea from a single sexual encounter with an infected woman. A woman, however, has about a one-in-two chance of getting it from an infected man. This difference comes down to how the bacterium infects male and female bodies differently.
In addition, having gonorrhea makes it easier to contract or transmit HIV. Therefore, treating gonorrhea promptly is important not only for your own health but also for your partner’s health.
How Gonorrhea Infects the Body
Neisseria gonorrhoeae is a remarkably clever bacterium. It has developed ways to avoid being destroyed by the human immune system. Understanding how it works helps explain why it can be so hard to detect and treat.
How Gonorrhea Infects Men
In men, the bacterium targets the lining of the urethra — the tube that carries urine out of the body. Within hours of exposure, the bacteria attach to the cells lining the urethra. They do this using tiny hair-like structures on their surface called pili.
These pili latch onto specific proteins on the surface of urethral cells. Once attached, the bacteria enter the cells and begin to multiply inside them. The bacteria also release substances that keep the infected cells alive longer than normal. This allows the bacteria more time to multiply before the immune system notices the infection.
After about 40 hours, enough bacteria have built up that the body begins to respond. The immune system sends white blood cells to fight the infection. This response causes the inflammation and discharge that are classic symptoms in men.
How Gonorrhea Infects Women
In women, the infection is more complex. The bacteria first target the cells of the cervix — the lower part of the uterus. These cervical cells have special proteins on their surface that the bacteria use to gain entry.
The bacterium uses a combination of its pili and other surface proteins to attach to and enter cervical cells. Once inside, the bacteria are wrapped in a kind of protective pocket formed by the cell membrane itself. This shields them from the immune system.
Furthermore, the bacteria release enzymes that help them move deeper into the tissue. This is why gonorrhea in women can spread more easily to the uterus and fallopian tubes if left untreated. As a result, untreated gonorrhea is a leading cause of pelvic inflammatory disease (PID) and infertility in women.
Gonorrhea Symptoms to Watch For
One of the biggest challenges with gonorrhea is that many people have no symptoms at all. This is especially true for women. However, when symptoms do appear, they usually show up within one to fourteen days after exposure. For more information on what to expect, the Mayo Clinic’s gonorrhea overview is a helpful resource.
Symptoms in Men
A burning or painful feeling when urinating
A white, yellow, or green discharge from the penis
Swollen or painful testicles
Anal discharge, itching, or pain (if the rectum is infected)
Symptoms in Women
Increased vaginal discharge
Pain or burning when urinating
Bleeding between periods or after sex
Pelvic or lower abdominal pain
Symptoms in the Throat and Eyes
Gonorrhea can also infect the throat after oral sex, or the eyes if bacteria come into contact with them. A throat infection often causes no symptoms or mild soreness. An eye infection can cause redness, swelling, and discharge.
In newborns, gonorrhea can infect the eyes during birth. This is why Canadian hospitals routinely screen pregnant women for STIs and treat newborns’ eyes as a precaution.
How Gonorrhea Is Diagnosed
Getting tested is the only way to know for sure if you have gonorrhea. Testing is simple, fast, and available across Canada through your family doctor, a walk-in clinic, or a sexual health centre.
A doctor or nurse will typically take a swab from the affected area — such as the urethra, cervix, throat, or rectum. A urine sample may also be used. Results usually come back within a few days. Many provinces also offer anonymous testing through public health units, so cost and privacy are rarely a barrier.
The World Health Organization’s fact sheet on gonorrhea recommends that sexually active people with multiple partners get tested regularly, even if they feel fine.
Treatment Options for Gonorrhea in Canada
Gonorrhea is treated with antibiotics. In Canada, the standard treatment is a combination of two antibiotics given together. This approach is used because some strains of gonorrhea have become resistant to certain antibiotics over time.
Your doctor or clinic will advise you on the right treatment for you. It is very important to take all the medication as directed, even if your symptoms clear up quickly. Stopping early can allow the infection to return and may contribute to antibiotic resistance.
In addition, you should avoid sexual contact until both you and your partner have completed treatment and a follow-up test confirms the infection is gone. You should also inform any recent sexual partners so they can get tested and treated if needed. Many sexual health clinics offer confidential partner notification services.
Most provincial health plans in Canada cover STI testing and treatment. If you are unsure about coverage in your province, your family doctor or a public health nurse can help you find the right care at little or no cost.
When to See a Doctor
You should see a doctor or visit a walk-in clinic as soon as possible if you think you may have gonorrhea. Do not wait for symptoms to get worse. Early treatment prevents complications and protects your partners.
You should also get tested if a sexual partner has told you they have gonorrhea, even if you feel completely fine. Remember, many people have no symptoms at all. If you are sexually active with new or multiple partners, regular STI testing — at least once a year — is a smart part of your overall health routine.
Your family doctor is a great first contact. Walk-in clinics and sexual health centres are also excellent options across most Canadian cities and towns. You do not need a referral to visit a sexual health clinic. As always, speaking with a healthcare professional is the best way to get advice tailored to your personal situation.
Frequently Asked Questions About Gonorrhea
Can gonorrhea go away on its own without treatment?
No, gonorrhea does not go away on its own. Without treatment, the infection can spread to other parts of the body and cause serious complications, including infertility. Always see a doctor or visit a walk-in clinic for proper antibiotic treatment.
Is gonorrhea testing free in Canada?
In most provinces, gonorrhea testing is covered under provincial health plans when ordered by a doctor or nurse practitioner. Many sexual health centres and public health units also offer free or low-cost testing. Check with your local health authority to confirm what is available in your area.
Can you get gonorrhea from oral sex?
Yes, gonorrhea can spread through oral sex. The infection can affect the throat and often causes no symptoms, which means it can be passed on without either person knowing. Using a condom or dental dam during oral sex reduces this risk.
How long does it take for gonorrhea symptoms to appear?
Gonorrhea symptoms usually appear within one to fourteen days after exposure. However, many people — especially women — never develop noticeable symptoms. This is why regular testing is so important for sexually active Canadians.
Can gonorrhea be cured completely?
Yes, gonorrhea can be cured with the right antibiotic treatment. However, some strains are becoming resistant to common antibiotics, so it is important to follow your doctor’s instructions carefully and complete the full course of medication. A follow-up test is often recommended to confirm the infection is gone.
Can gonorrhea affect fertility?
Yes, untreated gonorrhea is a leading cause of infertility in both men and women. In women, it can spread to the uterus and fallopian tubes, causing pelvic inflammatory disease. In men, it can affect the tubes that carry sperm. Early treatment greatly reduces the risk of long-term complications.
