Can Worms Cause Infertility? Understanding the Link Between Parasitic Infections and Fertility

Most common parasitic infections are not directly related to infertility. However, there are several parasitic infections that may affect your reproductive health. Certain parasites may indirectly contribute to infertility by causing inflammation and damage to the reproductive organs. Our experts explain the link and when to receive professional help.

Millions of couples around the globe are struggling with infertility issues due to different causes. The common causes include hormonal disorders, ovulation problems, and structural abnormalities. There are certain infections that may affect the reproductive process. However, most of the intestinal parasites causing worm infestation in the gut do not lead to infertility directly.
Some other parasitic infections, particularly affecting reproductive organs, may lead to infertility problems if left untreated.

Recognising the early signs of worm infections is important for timely diagnosis. If treatment is provided on time, it may help prevent long-term complications.

What Does Worm Infestation Mean?

Worm infections are caused by parasitic organisms that may enter our bodies if we fail to maintain proper hand and food sanitation. They use your body to feed, grow, and lay eggs in your intestine.

The following are some common worm infections:

  • Roundworms
  • Pinworms
  • Hookworms
  • Tapeworms
Many people experience either mild or no symptoms.

Most infections can be treated successfully using appropriate deworming medicines.

What Factors Increase the Risk of Worm Infections?

Your risk may be higher if you:

  • Consume contaminated food or water
  • Walk barefoot in contaminated soil
  • Have poor hand hygiene
  • Live in or travel to areas where parasitic infections are common
  • Have poor sanitation facilities

What Symptoms Are Associated With Worm Infection?

Symptoms depend on the type of parasite.

Common symptoms include:

  • Abdominal pain
  • Bloating
  • Nausea
  • Diarrhoea
  • Weight loss
  • Fatigue
  • Itching around the anus (common with pinworm infection)
  • Passing worms in the stool
  • Anaemia
Some people may not develop any symptoms despite being infected.

How Is Worm Infection Linked To Infertility?

In most people, the presence of worms will not affect fertility. Generally, common intestinal worms such as roundworms, pinworms, or hookworms do not directly affect fertility outcomes. However, certain parasitic infections may indirectly affect your fertility. This may happen due to the following reasons:

  • Chronic inflammation
  • Damage to reproductive organs
  • Poor nutritional status due to prolonged infection
One important example is female genital schistosomiasis, which is caused by “Schistosoma haematobium”.

According to current research, there is an association between female genital schistosomiasis and infertility. However, this association does not apply to all types of worm infections.

Which Worm Infection May Affect Your Fertility?

Certain worm infestations are more likely to cause reproductive issues than others.

Type of worm infection
How it may affect your fertility outcomes
Female genital schistosomiasis (caused by Schistosoma haematobium)
May cause:
  • Chronic inflammation
  • Scarring of reproductive tissues
  • Fallopian tube damage
  • Difficulty conceiving
Chronic pelvic schistosomiasis
May lead to:

  • Long-term inflammation
  • Damage to the pelvic reproductive organs
These complications may increase the risk of infertility.
Severe hookworm infection
Does not directly cause infertility, but may contribute indirectly through:
  • Long-term iron-deficiency anaemia
  • Malnutrition
  • Poor overall health
On the other hand, common intestinal worms such as pinworms and roundworms have not been shown to directly cause infertility.

What Diagnostic Tests Help To Confirm Worm Infections?

Your doctor will review your symptoms and medical history before recommending investigations.

Depending on the suspected infection, they may advise the following:

  • Stool examination
  • Blood tests
  • Urine tests for schistosomiasis
  • Imaging or endoscopy in selected cases
However, not everyone with digestive symptoms requires thorough testing. Your doctor will recommend testing only if they find it important after assessing your symptoms and risk factors.

Effect of Worm Infection Treatment On Fertility Outcomes

Treating a worm infection can prevent further complications and improve your overall health.

However, if infertility is caused by permanent damage to the reproductive organs, treatment may not completely restore fertility.

If your infertility is due to another medical condition, deworming alone is unlikely to improve your chances of conception.

If you have been trying to conceive and also have symptoms of a parasitic infection, speak with your doctor. Early diagnosis and appropriate treatment can help protect your reproductive health and reduce the risk of long-term complications.
