What is recurrent miscarriage?
Recurrent miscarriage, also called recurrent pregnancy loss, generally refers to two or more spontaneous pregnancy losses. Current ASRM guidance does not require the losses to be consecutive.
How many miscarriages are considered recurrent miscarriage?
The current ASRM definition uses two or more pregnancy losses. You do not necessarily have to experience three miscarriages before discussing evaluation with a specialist.
Why do recurrent miscarriages happen?
Possible causes include chromosomal abnormalities, uterine abnormalities, antiphospholipid syndrome, thyroid or metabolic problems, genetic factors and some male factors. In many patients, no specific cause is found.
Can recurrent miscarriage be treated?
In some cases, an underlying cause can be identified and treated. For example, certain uterine abnormalities or antiphospholipid syndrome may have specific management options. However, there is no treatment that prevents every miscarriage.
Can I have a successful pregnancy after recurrent miscarriage?
Yes. Many patients with recurrent pregnancy loss subsequently have a successful pregnancy. ASRM's 2026 guidance reports that approximately 50%–80% may have a successful subsequent pregnancy, although individual prognosis varies.
Does recurrent miscarriage mean I cannot have children?
No. Recurrent miscarriage does not mean that having a successful pregnancy is impossible. A fertility specialist can evaluate potential causes and discuss options for a future pregnancy.
Is recurrent miscarriage the same as infertility?
No. Infertility concerns difficulty achieving a successful pregnancy, whereas recurrent pregnancy loss concerns repeated pregnancy losses after conception. A person can have recurrent miscarriage without infertility.
What tests are done after recurrent miscarriage?
Depending on your history, evaluation may include chromosome testing of miscarriage tissue, uterine cavity evaluation, targeted blood tests, thyroid testing when indicated, antiphospholipid antibody testing when appropriate, genetic evaluation and male-partner assessment. Not every patient needs every test.
Can miscarriage tissue be tested?
Yes. When tissue is available and testing is feasible, chromosome analysis can provide useful information about whether the pregnancy had a chromosomal abnormality. Current ASRM guidance recommends array-based chromosome testing of miscarriage tissue when possible.
Can thyroid problems cause recurrent miscarriage?
Thyroid disorders can affect reproductive and pregnancy health. Your doctor may recommend thyroid testing depending on symptoms, risk factors and pregnancy-loss history.
Can PCOS cause recurrent miscarriage?
PCOS may be associated with several reproductive and metabolic factors, but recurrent miscarriage should not automatically be attributed to PCOS. A proper evaluation is needed to identify other possible causes.
Is IVF necessary after recurrent miscarriage?
No. IVF is not automatically required simply because a patient has experienced recurrent miscarriage. It may be considered when infertility or another indication for IVF is present, or in selected genetic circumstances.
Can PGT-A prevent recurrent miscarriage?
PGT-A can identify some chromosome-number abnormalities in embryos created through IVF, but it is not guaranteed to prevent miscarriage and is not routinely appropriate for every patient with recurrent pregnancy loss.
Should both partners be evaluated?
Yes. Recurrent pregnancy loss can involve factors related to either partner, so a complete assessment may include both partners.
Can sperm DNA fragmentation cause recurrent miscarriage?
Some evidence links increased sperm DNA fragmentation with recurrent pregnancy loss. Current ASRM guidance considers sperm DNA fragmentation testing in selected patients with recurrent unexplained pregnancy loss rather than as a universal test.
Should I take aspirin after recurrent miscarriage?
Do not start aspirin on your own. Aspirin may be appropriate in certain medical situations, such as specific cases of antiphospholipid syndrome, but it is not a universal treatment for recurrent miscarriage. Discuss it with your fertility specialist.
Should I take progesterone after recurrent miscarriage?
Progesterone treatment is not appropriate for every patient with recurrent miscarriage. Whether it has a role depends on the clinical situation and pregnancy history. Your doctor should decide whether progesterone is appropriate rather than using it routinely without assessment.
Can stress cause recurrent miscarriage?
Miscarriage is usually not caused by ordinary emotional stress or something a woman did or failed to do. After recurrent miscarriage, however, emotional stress and anxiety can be significant and deserve appropriate support.
