Understanding the Causes of Female Infertility: A Complete Guide

Many women ask, “Why can’t I get pregnant?” Understanding the causes of female infertility is important for anyone trying to conceive. Knowing the reasons can help you take the right steps. In this guide, we explain the main female infertility causes, risk factors, and ways to prevent them. We also discuss when to see a specialist for help.

What is Female Infertility?

Female infertility means a woman cannot get pregnant after one year of regular, unprotected sex. For women over 35, doctors may check sooner, after six months. Infertility can be stressful, but many causes have treatments. According to the World Health Organization (WHO), about 1 in 6 people worldwide face infertility at some point.

Common Causes of Female Infertility

There are many reasons why a woman may have trouble getting pregnant. Let’s look at the most common female infertility causes.

Ovulation Disorders

First, problems with ovulation are a leading cause. Ovulation is when the ovary releases an egg each month. If this does not happen, pregnancy cannot occur. Some common ovulation disorders include:

  • Polycystic ovary syndrome (PCOS)
  • Thyroid problems (too much or too little hormone)
  • High levels of prolactin (a hormone)
  • Extreme stress or sudden weight changes
  • Because these issues affect hormone balance, they can stop eggs from being released.

    Fallopian Tube Damage or Blockage

    Next, the fallopian tubes carry eggs from the ovaries to the uterus. If these tubes are blocked or damaged, sperm cannot reach the egg. Common reasons for tube problems include:

  • Pelvic inflammatory disease (often from infections like chlamydia or gonorrhea)
  • Previous surgeries in the pelvic area
  • Past ectopic pregnancy (when a pregnancy grows outside the uterus)
  • As a result, eggs and sperm cannot meet, making pregnancy hard.

    Endometriosis

    Endometriosis is a condition where tissue like the lining of the uterus grows outside it. This can cause pain and scarring. Sometimes, it blocks the fallopian tubes or affects the ovaries. According to the CDC, endometriosis affects about 11% of women between 15 and 44 years old. Because it can damage reproductive organs, it is a key infertility risk factor in women.

    Uterine or Cervical Causes

    Problems with the uterus or cervix can also lead to infertility. For example, some women have:

  • Fibroids (non-cancerous growths in the uterus)
  • Polyps (small growths on the uterine lining)
  • Abnormal shape of the uterus
  • Cervical mucus problems (making it hard for sperm to swim)
  • Because these issues can stop a fertilized egg from implanting, they may prevent pregnancy.

    Age and Lifestyle Factors

    As women age, fertility naturally drops. After age 35, the number and quality of eggs decrease. In addition, lifestyle choices can affect fertility. Some risk factors include:

  • Smoking or heavy alcohol use
  • Being overweight or underweight
  • High stress levels
  • Exposure to toxins (like pesticides or chemicals)
  • Because these factors can harm the ovaries or hormones, they play a role in female infertility causes.

    Unexplained Infertility

    Sometimes, doctors cannot find a clear reason for infertility. This is called unexplained infertility. It happens in about 10% of couples. Even though tests are normal, pregnancy does not occur. In these cases, doctors may suggest lifestyle changes or fertility treatments.

    Diagnosis: How Doctors Identify the Causes

    Doctors use several tests to find out why a woman cannot get pregnant. Usually, the process starts with a medical history and physical exam. Then, doctors may recommend:

  • Blood tests to check hormone levels
  • Ultrasound to look at the ovaries and uterus
  • Hysterosalpingography (an X-ray to check fallopian tubes)
  • Laparoscopy (a minor surgery to look inside the pelvis)
  • Because each woman is different, doctors choose tests based on her symptoms and history.

    Prevention and Lifestyle Guidance

    While not all causes can be prevented, some steps may lower the risk. Here are tips on how to prevent female infertility:

  • Maintain a healthy weight
  • Avoid smoking and limit alcohol
  • Manage stress with relaxation or exercise
  • Practice safe sex to prevent infections
  • See your doctor for regular check-ups
  • Because early action can help, talk to your doctor if you have concerns.

    When to See a Specialist

    If you have tried to get pregnant for a year without success, see a fertility specialist. For women over 35, seek help after six months. Also, see a doctor sooner if you have:

  • Irregular or missed periods
  • Severe pelvic pain
  • History of pelvic infections or surgery
  • Known fertility problems
  • Because early diagnosis can improve your chances, do not wait to ask for help.
