Female Infertility: Causes, Symptoms, Diagnosis and Treatment

What Is Female Infertility?

Female infertility is a reproductive health condition in which a woman experiences difficulty becoming pregnant or carrying a pregnancy to term. Infertility is generally defined as the inability to achieve pregnancy after 12 months of regular, unprotected sexual intercourse. For women aged 35 and older, a fertility evaluation is generally recommended after six months of trying. Earlier assessment may be appropriate when known reproductive health concerns are present.

Female infertility can be associated with several factors, including age-related changes in egg quality and quantity, hormonal imbalances, ovulation disorders, conditions affecting the uterus or fallopian tubes, and certain lifestyle or medical factors.

Infertility can affect women at different stages of life, and the underlying cause varies from person to person. A proper medical evaluation can help identify possible contributing factors and guide decisions about treatment.

At Jyoti IVF, understanding the causes of female infertility is an important step towards helping women and couples explore suitable fertility care.

What Are the Causes of Female Infertility?

Female infertility may result from hormonal, structural, age-related, or other reproductive health factors. In some cases, more than one factor may contribute to difficulty conceiving.

1. Age-Related Changes

Age is an important factor affecting female fertility. Women are born with a finite supply of eggs, and both the number and quality of eggs generally decline with age.

This decline becomes more pronounced during the later reproductive years and can affect the chances of conception, embryo development, and the risk of miscarriage. However, fertility varies between individuals, and age alone cannot determine whether a woman will be able to conceive.

2. Hormonal Imbalances and Ovulation Disorders

Hormones regulate the menstrual cycle and the release of eggs from the ovaries. Conditions that interfere with this process may make conception more difficult.

Examples include:

• Polycystic ovary syndrome (PCOS): A hormonal condition that can cause irregular periods and infrequent or absent ovulation.
• Thyroid disorders: Both an underactive and an overactive thyroid may affect menstrual function and fertility.
• Elevated prolactin levels: High levels of prolactin may interfere with ovulation.
• Other ovulatory disorders: Some conditions may prevent the regular development or release of an egg.

Women with irregular periods, absent periods, or other signs of hormonal changes may benefit from a fertility assessment.

3. Endometriosis

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus. It may cause pelvic pain, painful periods, and difficulties with fertility.

Depending on its location and severity, endometriosis may affect the ovaries, fallopian tubes, or surrounding pelvic structures. Not every woman with endometriosis experiences infertility, and treatment depends on individual symptoms and reproductive goals.

4. Uterine Fibroids and Polyps

Uterine fibroids are growths that develop in or around the uterus, while uterine polyps are growths arising from the uterine lining.

Their impact on fertility depends on their size, number, and location. Some may interfere with the uterine cavity or implantation, while others may have little or no effect on fertility.

A specialist may recommend monitoring or treatment depending on the findings and the patient’s medical history.

5. Blocked or Damaged Fallopian Tubes

The fallopian tubes help sperm reach the egg and allow the fertilised egg to travel towards the uterus. If the tubes are blocked or damaged, natural fertilisation may become difficult or impossible, depending on the extent and location of the problem.

Possible causes include previous pelvic infections, pelvic inflammatory disease, endometriosis, or prior surgery.

6. Structural Abnormalities of the Uterus

Some uterine conditions may affect implantation or pregnancy. These can include a uterine septum, adhesions inside the uterus, or certain other structural abnormalities.

The clinical significance varies according to the type of abnormality. Further investigations may be recommended to determine whether treatment is appropriate.

What Are the Risk Factors for Female Infertility?

Several factors may increase the likelihood of fertility difficulties. Having a risk factor does not necessarily mean that a woman will experience infertility.

Common factors include:

• Increasing age: Fertility generally declines as women get older.
• Smoking and tobacco use: These may adversely affect reproductive health and egg quality.
• Excessive alcohol consumption: Alcohol may affect reproductive and general health.
• Certain medical conditions: PCOS, endometriosis, thyroid disorders, and other hormonal conditions may affect fertility.
• Previous pelvic infections: Some sexually transmitted infections and pelvic inflammatory disease can cause scarring or damage to the fallopian tubes.
• Previous pelvic or reproductive surgery: Depending on the procedure, surgery may sometimes lead to adhesions or changes in reproductive anatomy.
• Weight-related factors: Being significantly underweight or overweight may affect hormonal function and ovulation in some women.
• Certain medical treatments: Chemotherapy, radiation therapy, and some other treatments may affect ovarian function.

If you have concerns about any of these factors, a healthcare professional can help assess your individual risk and advise whether further testing is needed.

What Are the Signs and Symptoms of Female Infertility?

Female infertility does not always cause noticeable symptoms. Some women have regular menstrual cycles and no obvious symptoms but still experience difficulty conceiving.

Possible signs that warrant medical assessment include:

• Irregular, infrequent, or absent menstrual periods.
• Periods that are unusually painful or heavy.
• Persistent pelvic pain.
• Pain during sexual intercourse.
• Symptoms associated with hormonal changes, such as unusual hair growth or persistent acne.
• A known history of endometriosis, PCOS, pelvic inflammatory disease, or other reproductive conditions.
• Difficulty becoming pregnant after the recommended period of trying.

These symptoms do not necessarily indicate infertility, but they may suggest an underlying condition that requires evaluation.

How Is Female Infertility Diagnosed?

The evaluation is tailored to the individual’s medical history, age, menstrual pattern, symptoms, and how long pregnancy has been attempted. Depending on the circumstances, the doctor may recommend one or more of the following investigations.

1. Medical History and Physical Examination

The doctor may review menstrual history, previous pregnancies, medical conditions, medications, surgeries, and any history of pelvic infections or reproductive health concerns.

A physical examination may be recommended when clinically appropriate.

2. Blood Tests

Blood tests can help evaluate selected hormones and other factors that may affect fertility.

Depending on the clinical assessment, investigations may include tests for thyroid function, prolactin, or hormones associated with ovarian function and ovulation. Anti-Müllerian hormone (AMH) may be used as part of an ovarian reserve assessment, but it cannot independently determine whether a woman can conceive naturally.

The specific tests recommended will depend on the individual’s circumstances.

3. Pelvic Ultrasound

A pelvic ultrasound uses sound waves to examine the reproductive organs, including the uterus and ovaries.

It may help identify ovarian cysts, fibroids, certain uterine abnormalities, and features associated with PCOS. Ultrasound findings may also help assess the ovaries and monitor follicular development when needed.

An ultrasound cannot detect every possible cause of infertility, so additional investigations may sometimes be necessary.

4. Hysterosalpingography (HSG)

A hysterosalpingography, or HSG, is an imaging test used to assess the uterine cavity and whether the fallopian tubes appear open.

During the procedure, contrast dye is introduced through the cervix into the uterus, and X-ray images are taken to observe the flow of the dye.

HSG may help identify possible tubal blockage or certain abnormalities of the uterine cavity. The doctor will determine whether the test is suitable based on the patient’s medical history.

5. Additional Investigations

Some women may need further evaluation depending on their symptoms and initial test results. This may include additional imaging or a procedure to examine the uterine cavity more closely.

A fertility assessment may also include evaluation of the male partner, as fertility difficulties can involve either partner or both.

What Are the Treatment Options for Female Infertility?

Treatment depends on the underlying cause, the woman’s age and reproductive health, the duration of infertility, and the couple’s preferences. Not every woman requires the same treatment, and pregnancy cannot be guaranteed with any fertility procedure.

1. Lifestyle Changes

Healthy lifestyle habits can support general and reproductive health. Depending on the individual’s circumstances, a doctor may recommend:

• Maintaining a healthy weight.
• Eating a balanced diet.
• Exercising regularly.
• Avoiding smoking and tobacco products.
• Avoiding alcohol when trying to conceive and during pregnancy.
• Managing existing health conditions.
• Reviewing medications and supplements with a healthcare professional.

Lifestyle changes may be helpful in some cases, but they cannot correct every underlying cause of infertility.

2. Ovulation Induction and Medication

Women who do not ovulate regularly may benefit from medication to encourage egg development and release.

Depending on the diagnosis, a doctor may recommend medicines such as letrozole or clomiphene citrate. Gonadotropin injections may be used in selected cases.

Treatment may involve ultrasound monitoring and, where appropriate, blood tests to assess the response. Medication choice and dosage should be determined by a qualified specialist because ovarian stimulation can carry risks, including multiple pregnancy and ovarian hyperstimulation.

3. Surgical Treatment

Surgery may be considered when a specific structural problem is likely to affect fertility.

Depending on the diagnosis, procedures may be used to treat certain uterine abnormalities, remove selected fibroids or polyps, or address some forms of endometriosis or tubal disease.

Surgery is not appropriate for every patient, and its potential benefits should be weighed against its risks and the possibility of alternative treatments.

4. In Vitro Fertilisation (IVF)

In vitro fertilisation (IVF) is an assisted reproductive technique in which eggs are collected from the ovaries and fertilised with sperm in a laboratory. The resulting embryo may then be transferred into the uterus.

IVF may be considered when the fallopian tubes are blocked or significantly damaged, when other fertility treatments have not been successful, or when the clinical assessment suggests IVF is an appropriate option.

The treatment process generally includes ovarian stimulation, egg retrieval, fertilisation, embryo development, and embryo transfer. Some embryos may be frozen for future use, depending on the treatment plan.

IVF outcomes vary according to factors such as age, egg and embryo characteristics, sperm factors, and underlying medical conditions.

5. Intracytoplasmic Sperm Injection (ICSI)

Intracytoplasmic sperm injection (ICSI) is a laboratory technique used during IVF in which a single sperm is injected directly into a mature egg.

It may be recommended when there are significant sperm-related concerns or previous fertilisation difficulties. ICSI is not necessary for every IVF cycle; the specialist will advise whether it is appropriate for the couple.

6. Other Assisted Reproductive Options

Other approaches may be considered in selected situations, depending on the diagnosis and applicable medical and regulatory guidance.

The most suitable option depends on factors such as tubal function, ovulation, sperm parameters, previous treatment outcomes, and the couple’s reproductive goals. A fertility specialist can explain the available alternatives, their potential benefits, limitations, risks, and costs.

Can Female Infertility Be Prevented?

Not all causes of female infertility can be prevented. Age-related changes, genetic conditions, and some medical disorders cannot be fully controlled through lifestyle choices.

However, certain steps may support reproductive health:

• Seek medical advice for persistently irregular or absent periods.
• Get timely assessment for symptoms such as severe pelvic pain or unusually painful periods.
• Seek appropriate care for sexually transmitted infections and pelvic infections.
• Avoid smoking and tobacco products.
• Discuss fertility preservation before treatments that may affect ovarian function.
• Manage existing medical conditions with professional guidance.
• Consult a healthcare professional before using fertility supplements or hormonal medication.

Early evaluation may help identify some treatable conditions, but it cannot guarantee future fertility.

When Should You Consult a Fertility Specialist?

Consider seeking a fertility evaluation if you have been trying to conceive for 12 months without success, or after six months if you are aged 35 or older.

An earlier consultation may be appropriate if you have irregular or absent periods, known endometriosis, a history of pelvic infection, suspected tubal problems, or another medical condition that may affect fertility.

A specialist can help identify possible causes, recommend appropriate investigations, and discuss treatment options based on your individual needs.
