fertility with fever

Overview

Fever is a temporary rise in body temperature, usually caused by an infection. When you have a fever, it can sometimes disrupt your menstrual cycle or the release of an egg, which is called ovulation. The effect is usually short-term, and most fevers do not cause lasting fertility problems.

Yes. Fever is a common symptom of many infections, such as flu, colds, and urinary tract infections. Many women experience a fever at some point during their reproductive years, and it may happen while they are trying to conceive.

It affects women of reproductive age who are trying to get pregnant, are already pregnant, or are planning fertility treatment. It can also be a concern for women who are tracking their cycles and notice changes after a fever.

Symptoms

Common symptoms

• Elevated body temperature – usually 38°C (100.4°F) or higher
• Chills and sweating
• Headache or muscle aches
• Feeling tired or weak
• Sometimes a change in your usual menstrual cycle pattern

Causes

Main causes

• Infections – viral (like flu or a cold) or bacterial (like a urinary tract infection)
• Inflammatory conditions – such as autoimmune diseases
• Some other medical issues – like certain cancers or blood disorders
• After some vaccinations (this is usually mild and short-lived)

Risk factors

• Being in close contact with sick people
• Having a weakened immune system
• Travel to areas with specific infections
• Being pregnant or very recently pregnant
• Undergoing fertility treatments that involve procedures

When to see a doctor

See a doctor urgently if:

• If you are pregnant and have a fever, contact your maternity unit or doctor the same day
• If the fever is above 39.5°C (103°F) and does not come down with home care
• If you have a fever with severe pain, stiffness in the neck, or trouble breathing

Book a routine appointment if:

• If you have a fever that lasts more than two days
• If you have missed two or three menstrual periods after a fever and are concerned about fertility
• If you are trying to conceive and want a check-up before continuing

Diagnosis

A doctor will listen to your symptoms, check your temperature, and examine you. They may ask about your menstrual cycle and any fertility plans. The main goal is to find the cause of the fever and, if needed, check how it might affect your fertility.

Tests that may be done

• Blood tests – to check for infection or inflammation
• Urine test – to check for a urinary tract infection
• Swab test – from your throat or vagina, if needed
• Ultrasound – in some cases, to check the uterus and ovaries

What to expect at your appointment

Your doctor will explain what tests you need and why. After the results, they will talk to you about treatment and any steps you can take to protect your fertility.

Treatment

Treatment for fever with fertility concerns focuses on the cause of the fever and helping you feel better. In most cases, treating the underlying infection will allow your body to return to its normal cycle. If your cycles are irregular after a fever, your doctor may suggest tracking and planning.

Self-care at home

• Get plenty of rest
• Drink fluids like water, herbal tea, or clear soups to stay hydrated
• Dress lightly to help your body cool down
• Use a cool compress on your forehead if it helps
• Take fever-reducing medicine only after checking with a pharmacist or doctor

Medical treatments

Depending on the cause, a doctor may prescribe antibiotics for a bacterial infection or other medicines to treat the underlying problem. If you are trying to become pregnant, your doctor may also suggest ways to monitor your cycle and time intercourse more effectively. Never take any new medication without checking whether it is safe for your fertility or a possible pregnancy.

When is surgery considered?

Surgery is rarely needed for fever alone. It may be considered only if the fever comes from a condition like appendicitis or an abscess that needs surgical drainage.

Living with this condition

While you have a fever, focus on rest and recovery. Once your temperature returns to normal, you can resume your usual activities. If you track your cycle, keep a notebook or app so you can share any changes with your doctor.

Lifestyle tips

• Try to reduce stress with deep breathing or gentle activities
• Get enough sleep each night
• Limit alcohol and avoid smoking
• If you are trying to conceive, try to keep a healthy weight

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, whole grains, and lean proteins. Light exercise like walking is helpful once you feel better, but avoid intense exercise during a fever.

Mental health and emotional wellbeing

Worrying about fertility can be stressful, and a fever may add to that worry. It is normal to feel anxious. If you are feeling overwhelmed, talking to a counselor or a support group can make a difference. If you are in crisis, reach out to a local crisis or mental health hotline.

Prevention

Not all fevers can be prevented, but good hygiene and avoiding close contact with sick people can lower your risk. If you are trying to conceive, staying healthy is one of the best things you can do.

Vaccines

Vaccines like the flu vaccine and COVID-19 vaccine can help prevent infections that cause fever. Ask your doctor or local health service about which vaccines are recommended for you.

Screening programmes

No special screening is needed for fever-related fertility issues, but regular check-ups with a gynecologist can help you stay on top of your reproductive health.

Complications

If left untreated

• Very high fever in early pregnancy may be associated with an increased risk of certain birth defects, although this is not common
• An untreated bacterial infection could spread and cause serious illness
• Prolonged high fever can temporarily stop ovulation, leading to a late or missed period

Long-term outlook

The good news is that most fevers are short-lived and do not cause lasting infertility. Once the infection clears, your body usually returns to its normal rhythm. Seeking prompt medical advice and being gentle with yourself are the best steps forward.
