Recurrent Pregnancy Loss: Causes, Tests & Treatment

Experiencing a miscarriage can be emotionally and physically difficult. While miscarriage is relatively common, recurrent pregnancy loss (RPL) requires medical evaluation to understand whether an underlying cause may be contributing to repeated pregnancy losses.

Recurrent pregnancy loss is a distinct reproductive health condition and is different from infertility. According to the latest American Society for Reproductive Medicine (ASRM) guidance, recurrent pregnancy loss is defined as two or more spontaneous pregnancy losses, excluding confirmed molar or ectopic pregnancies. The losses do not necessarily have to occur consecutively.

Many miscarriages, particularly those occurring early in pregnancy, are related to chromosomal abnormalities in the embryo. The likelihood of chromosomal abnormalities also increases with maternal age. However, recurrent pregnancy loss can have several possible causes, and sometimes no single cause is identified even after a detailed evaluation.

If you have experienced repeated miscarriages, consulting an experienced fertility specialist or obstetrician-gynaecologist can help determine whether further testing or treatment is appropriate.

What Is Recurrent Pregnancy Loss?

Recurrent pregnancy loss (RPL) refers to repeated spontaneous pregnancy losses.

Current ASRM guidance defines RPL as the spontaneous loss of two or more pregnancies, excluding confirmed molar and ectopic pregnancies. Pregnancy losses do not have to be consecutive for evaluation to be considered.

The term recurrent miscarriage is also commonly used. Older medical literature may use the term recurrent abortion, but “recurrent pregnancy loss” is generally preferred for patient-focused medical communication.

Recurrent pregnancy loss can be associated with genetic, anatomical, hormonal, metabolic, immune-related and other factors. In some couples, no clear cause is identified.

What Causes Recurrent Pregnancy Loss?

There is no single cause of recurrent miscarriage. A detailed evaluation may consider several factors involving the embryo, chromosomes, uterus, hormones, metabolism, and the health of both partners.

1. Chromosomal Abnormalities

Chromosomal abnormalities are an important cause of early pregnancy loss.

Approximately 50%–60% of first-trimester miscarriages are associated with embryonic aneuploidy, and the likelihood of aneuploidy is strongly influenced by maternal age.

Most chromosomal abnormalities occur sporadically during egg or embryo development. In some cases, however, chromosome abnormalities involving one of the parents may contribute to recurrent pregnancy loss.

When possible, chromosome testing of miscarriage tissue may provide useful information during recurrent pregnancy loss evaluation. The latest ASRM guidance recommends chromosome analysis of pregnancy-loss tissue, when feasible, as an important part of evaluation.

2. Uterine Abnormalities

Problems affecting the structure of the uterus may contribute to pregnancy loss in some women.

These may include:

Uterine septum
Certain congenital uterine anomalies
Fibroids
Endometrial polyps
Intrauterine adhesions

Your fertility specialist may recommend imaging or other investigations based on your history and symptoms.

3. Antiphospholipid Syndrome

Antiphospholipid syndrome (APS) is an autoimmune condition associated with abnormal blood clotting and specific pregnancy complications.

APS is an established and potentially treatable cause of recurrent pregnancy loss. Testing may be recommended when a patient’s history suggests an increased risk.

Treatment for confirmed obstetric APS may include medications such as low-dose aspirin and heparin under specialist supervision. These medicines should not be started without medical advice. Current evidence does not support routinely prescribing aspirin or anticoagulants to everyone with recurrent pregnancy loss.

4. Thyroid and Metabolic Conditions

Certain medical conditions may be associated with pregnancy loss.

Depending on the individual’s history, evaluation may include conditions such as:

Thyroid disease
Diabetes
Other metabolic disorders

The latest ASRM guidance supports targeted assessment for conditions such as thyroid disease and diabetes when clinically appropriate.

5. Age-Related Factors

Maternal age is an important factor in miscarriage risk because chromosomal abnormalities in eggs and embryos become more common with increasing age.

This does not mean that pregnancy after 35 is impossible or necessarily unsuccessful. However, age should be considered when evaluating recurrent pregnancy loss and planning future pregnancy.

6. Other Factors

Depending on the clinical history, doctors may also consider:

Genetic factors
Certain anatomical conditions
Lifestyle factors
Chronic medical conditions
Previous pregnancy complications

Not every proposed cause of recurrent miscarriage has strong evidence. Current guidelines recommend targeted evaluation rather than routinely performing every available test.

Recurrent Pregnancy Loss Symptoms

Recurrent pregnancy loss itself does not usually have a specific set of symptoms between pregnancies. The main concern is repeated pregnancy loss.

During an individual miscarriage, symptoms may include:

Vaginal bleeding or spotting
Lower abdominal or pelvic cramping
Back pain
Passing tissue or clots
Decreasing pregnancy symptoms

However, these symptoms do not always mean that a miscarriage is occurring. Bleeding and abdominal pain during pregnancy can have several causes.

Seek urgent medical care if you experience heavy bleeding, severe abdominal or pelvic pain, dizziness, fainting, fever or other concerning symptoms during pregnancy.

When Should You See a Doctor for Recurrent Miscarriage?

If you have experienced two or more pregnancy losses, it is reasonable to discuss recurrent pregnancy loss evaluation with a qualified obstetrician-gynaecologist or fertility specialist. Current ASRM guidance recognises RPL after two spontaneous pregnancy losses.

You should especially seek specialist advice if:

You have had two or more miscarriages.
You have experienced a second-trimester pregnancy loss.
You have irregular menstrual cycles.
You have a known uterine abnormality.
You have a history suggesting autoimmune or metabolic disease.
You or your partner has a known genetic condition.
You have been trying to conceive again after repeated pregnancy loss.

Tests for Recurrent Pregnancy Loss

There is no single test that can identify every cause of recurrent pregnancy loss.

Your doctor may recommend targeted investigations based on your pregnancy history, age, previous test results and other health factors.

Common Tests

Depending on the individual situation, evaluation may include:

Genetic Testing

Chromosome testing of pregnancy-loss tissue can help determine whether a chromosomal abnormality contributed to the miscarriage.

In selected cases, parental genetic testing may also be considered.

Uterine Evaluation

Tests used to assess the uterus may include:

Pelvic ultrasound
Transvaginal ultrasound
Saline infusion sonography
Hysterosalpingography (HSG)
Hysteroscopy
MRI in selected cases

The appropriate test depends on the suspected condition.

Antiphospholipid Antibody Testing

Testing for antiphospholipid syndrome may be recommended when clinically appropriate.

Thyroid and Metabolic Assessment

Your doctor may recommend blood tests to assess thyroid function, diabetes or other metabolic conditions depending on your medical history.

Evaluation of Other Health Factors

A detailed medical, reproductive and family history can help determine whether additional investigations are required.

Can Recurrent Pregnancy Loss Be Prevented?

There is no guaranteed way to prevent every miscarriage because many early pregnancy losses are caused by chromosomal abnormalities that occur during embryo development.

However, addressing treatable medical conditions and maintaining good preconception health may support a healthy pregnancy.

Steps That May Support a Healthy Pregnancy

Maintain a Healthy Lifestyle

Aim for a balanced diet, regular physical activity and a healthy weight appropriate for your individual circumstances.

Avoid Smoking and Tobacco

Smoking is associated with adverse reproductive and pregnancy outcomes. Avoid tobacco and exposure to tobacco smoke when planning pregnancy.

Avoid Alcohol During Pregnancy

Alcohol should be avoided during pregnancy.

Review Medications Before Pregnancy

Speak with your doctor before starting, stopping or changing any medication while trying to conceive or during pregnancy.

Manage Existing Health Conditions

Conditions such as diabetes and thyroid disease should be appropriately evaluated and managed before and during pregnancy.

Take Recommended Prenatal Supplements

Your doctor may recommend folic acid and other prenatal supplements based on your individual needs.

Attend Preconception Care

A preconception consultation can help identify medical or reproductive factors that may need attention before another pregnancy.

Recurrent Pregnancy Loss Treatment

Treatment for Recurrent Miscarriage depends on the underlying cause.

There is no single treatment that works for every couple.

After evaluation, treatment may involve:

Management of thyroid or metabolic conditions
Treatment of confirmed antiphospholipid syndrome
Treatment of certain uterine abnormalities
Genetic counselling
Fertility treatment where appropriate
Psychological and emotional support

Current guidelines emphasise evidence-based, targeted treatment and caution against the routine use of tests or therapies that have not demonstrated clear benefit.

Treatment for Uterine Abnormalities

If a uterine abnormality is identified and is considered relevant to the pregnancy losses, treatment may sometimes be recommended.

Depending on the condition, treatment can include procedures such as hysteroscopic surgery.

For example, a uterine septum may be treated surgically in selected patients after appropriate evaluation and counselling.

The decision to operate should be individualised rather than based solely on an ultrasound finding.

Treatment for Antiphospholipid Syndrome

Women with confirmed obstetric antiphospholipid syndrome may benefit from specific treatment during pregnancy.

Depending on the clinical situation, a specialist may prescribe low-dose aspirin and heparin or another appropriate anticoagulant.

These medications are not appropriate for everyone with recurrent miscarriage or for people without a confirmed indication. They can have important side effects and should only be used under medical supervision.

Can IVF Help With Recurrent Pregnancy Loss?

IVF is not automatically required for Recurrent Miscarriage

Many couples with recurrent pregnancy loss can achieve a successful pregnancy without IVF, depending on the cause, age and other fertility factors.

However, IVF may be considered when there is another indication for assisted reproductive treatment or in selected couples where genetic factors are relevant.

IVF allows eggs to be fertilised in the laboratory and embryos to be transferred to the uterus.

IVF and Genetic Testing

In selected cases, preimplantation genetic testing (PGT) may be discussed when there is a known genetic or chromosomal indication.

However, PGT is not a universal treatment for recurrent pregnancy loss. The benefits, limitations, cost and possibility of obtaining a suitable embryo should be discussed with a fertility specialist.

Current ASRM guidance notes that evidence concerning PGT-A in recurrent pregnancy loss is still nuanced, and treatment should be individualised rather than offered routinely to every patient with RPL.

Chances of a Successful Pregnancy

Experiencing recurrent miscarriage does not mean that a future healthy pregnancy is impossible.

The outcome depends on several factors, including:

Maternal age
Number and timing of previous pregnancy losses
Chromosomal findings
Underlying medical conditions
Uterine factors
Whether a treatable cause is identified

Importantly, many cases remain unexplained even after evaluation. The latest ASRM guidance reports that 50%–80% of patients with unexplained recurrent pregnancy loss may go on to have a successful pregnancy, depending on individual circumstances.

Your individual prognosis should be discussed with your fertility specialist rather than estimated from a general percentage.

Emotional Support After Recurrent Miscarriage

Recurrent Miscarriage can be emotionally challenging for both partners.

Feelings of sadness, anxiety, grief, frustration or fear during a subsequent pregnancy are understandable.

Psychological support and counselling are an important part of recurrent pregnancy loss care. Current ASRM guidance specifically recommends emotional support for patients and couples experiencing RPL.

Seeking professional support does not mean that your concerns are being dismissed. Emotional wellbeing is an important part of reproductive healthcare.

Frequently Asked Questions

What is recurrent pregnancy loss?

Recurrent pregnancy loss is generally defined as two or more spontaneous pregnancy losses. Current ASRM guidance does not require the losses to be consecutive.

Is recurrent abortion the same as recurrent miscarriage?

The terms may be used to describe repeated pregnancy loss, but recurrent pregnancy loss (RPL) is the preferred modern clinical terminology for patient education.

How many miscarriages are considered recurrent pregnancy loss?

Current ASRM guidance defines recurrent pregnancy loss as two or more spontaneous pregnancy losses.

What is the most common cause of recurrent miscarriage?

Chromosomal abnormalities are a major cause of early pregnancy loss. However, recurrent pregnancy loss can have several possible causes, and some cases remain unexplained.

Can PCOS cause recurrent miscarriage?

PCOS may be associated with certain reproductive and metabolic risks, but recurrent pregnancy loss should not automatically be attributed to PCOS. A proper medical evaluation is needed to identify possible contributing factors.

Can thyroid problems cause recurrent miscarriage?

Thyroid disorders can affect reproductive and pregnancy health. Appropriate thyroid assessment may be part of the evaluation of recurrent pregnancy loss when clinically indicated.

Can recurrent pregnancy loss be treated?

Yes, in some cases an underlying cause can be identified and treated. However, there is no single treatment for all cases of recurrent pregnancy loss.

Is IVF necessary after recurrent miscarriage?

No. IVF is not automatically required after recurrent miscarriage. It may be considered when there is another indication for IVF or in selected situations involving genetic or fertility factors.

Can IVF prevent miscarriage?

IVF cannot guarantee that miscarriage will be prevented. In selected cases, IVF with appropriate genetic testing may be discussed, but it is not a universal treatment.

Should I take aspirin or heparin after repeated miscarriages?

Do not start aspirin or heparin without medical advice. These medications may be appropriate for selected patients, particularly those with confirmed antiphospholipid syndrome, but they are not routinely recommended for everyone.

Can I have a healthy pregnancy after recurrent miscarriage?

Yes. Many people with recurrent pregnancy loss subsequently have a successful pregnancy. Your individual chances depend on factors such as age, medical history, previous pregnancy losses and whether an underlying cause is identified.

Take the Next Step After Recurrent Pregnancy Loss

Experiencing repeated pregnancy loss can be difficult, but it does not mean that a successful pregnancy is impossible.

The right approach is to identify possible causes, treat conditions that can be addressed and develop an individualised pregnancy or fertility plan.

If you have experienced two or more pregnancy losses, consider speaking with a qualified fertility specialist or obstetrician-gynaecologist for appropriate evaluation.
