Fehlgeburt-Risiko-Rechner
Verstehen Sie statistische Fehlgeburtenrisiken basierend auf mütterlichem Alter und Schwangerschaftswoche
Wichtiger Haftungsausschluss
Diese Statistiken sind Bevölkerungsdurchschnitte basierend auf medizinischen Forschungsstudien. Sie stellen allgemeine Risiken dar, nicht Ihr individuelles Ergebnis.
Dieser Rechner kann nicht vorhersagen, ob Sie eine Fehlgeburt haben werden. Die meisten Schwangerschaften verlaufen normal, selbst mit statistischen Risikofaktoren.
Konsultieren Sie immer Ihren Gesundheitsdienstleister für persönliche medizinische Beratung und Pflege.

Verständnis des Fehlgeburt-Risikos
Eine Fehlgeburt ist der spontane Verlust einer Schwangerschaft vor der 20. Woche. Das allgemeine Risiko einer Fehlgeburt ist oft höher als viele Menschen realisieren, aber das Risiko nimmt signifikant ab, wenn die Schwangerschaft fortschreitet und ein Herzschlag erkannt wird.
Wie Sich Das Risiko Pro Woche Ändert
Das Risiko einer Fehlgeburt ist in der frühen Schwangerschaft am höchsten. Nachdem ein Herzschlag um Woche 6-7 erkannt wurde, sinkt das Risiko signifikant. In Woche 12-13 (Ende des ersten Trimesters) ist das Risiko sehr niedrig (weniger als 1-2%). In Woche 20 ist das Risiko extrem selten.
Wie Das Alter Das Risiko Beeinflusst
Das mütterliche Alter ist einer der bedeutendsten Faktoren, die das Fehlgeburt-Risiko beeinflussen. Das Risiko nimmt schrittweise mit dem Alter zu, besonders nach Alter 35. Jedoch führen die meisten Schwangerschaften in allen Altern zu gesunden Geburten.
Die Meisten Schwangerschaften Sind Gesund
Selbst mit statistischen Risikofaktoren führt die überwältigende Mehrheit der Schwangerschaften zu gesunden Babys. Konzentrieren Sie sich auf das, was Sie kontrollieren können: pränatale Betreuung, Vitamine, gesunder Lebensstil und sich zu informieren, während Sie unnötige Ängste vermeiden.

Miscarriage risk falls steeply through the first trimester and rises with maternal age, and those two facts are what any risk figure is built from. It is worth being clear about what such a number can and cannot do: it describes what happens across a large population of pregnancies at a given point, and it cannot tell any individual whether their own pregnancy will continue.
How risk changes with gestational age
The steep decline through the first trimester is the most useful pattern here. Most losses occur early and are caused by chromosomal abnormalities that arose at conception, which is why risk drops sharply once a pregnancy has been shown to be developing normally. A confirmed fetal heartbeat on ultrasound is the single largest reduction in risk in early pregnancy.
- A very large proportion of conceptions are lost before a test would ever turn positive. These are not experienced as miscarriages and are not included in the commonly quoted figures.
- Figures vary between studies depending on how early pregnancies were detected and which losses were counted, so treat any single number as approximate.
| Point in pregnancy | Approximate remaining risk of loss |
|---|---|
| Before a positive test (biochemical loss) | A large share of all conceptions, mostly unrecognised |
| Positive test, before ultrasound | Roughly 1 in 5 clinically recognised pregnancies |
| Heartbeat seen at 6 weeks | Falls substantially, commonly cited around 10 percent |
| Heartbeat seen at 8 weeks | Falls further, commonly cited around 3 to 5 percent |
| After 12 weeks | Around 1 to 2 percent |
| After 20 weeks | Classified as stillbirth rather than miscarriage, and uncommon |
How risk changes with age
Maternal age is the strongest single predictor, and the mechanism is well understood: the proportion of eggs with chromosomal abnormalities rises with age, and most early losses are chromosomal. The pattern is a gentle rise through the thirties and a steep one after about 40.
- Paternal age has a smaller but measurable independent association.
- These are population figures. Two people of the same age with the same history can have very different outcomes, and the number does not distribute itself evenly across individuals.
| Maternal age | Approximate risk of clinically recognised loss |
|---|---|
| Under 30 | Around 10 percent |
| 30 to 34 | Around 12 percent |
| 35 to 39 | Around 20 percent |
| 40 to 44 | Around 40 percent |
| 45 and over | Over 50 percent |
What this does not mean
The single most important thing to say on a page like this is that miscarriage is almost never caused by anything the pregnant person did. Ordinary activity, exercise, working, sex, lifting, stress, a glass of wine before knowing, and travel are not causes. The overwhelming majority of first-trimester losses are chromosomal events determined at conception and were not preventable.
Recurrent loss is treated differently from a single event. Investigation is usually offered after two or three consecutive losses, and looks for the small number of identifiable and sometimes treatable causes: chromosomal rearrangements in either partner, antiphospholipid syndrome, uterine structural abnormalities and thyroid disease. Even after full investigation, no cause is found in roughly half of cases, and the outlook for a subsequent pregnancy remains good.
- Bleeding in early pregnancy is common and does not necessarily mean miscarriage, but it should always be reported to a clinician.
- Severe or one-sided pain, shoulder-tip pain, or faintness with bleeding needs emergency assessment for ectopic pregnancy.
Grenzen
- These are population statistics. They cannot predict the outcome of an individual pregnancy, and a low number is not reassurance nor a high one a prediction.
- Published figures vary considerably depending on how early pregnancies were detected, which losses were counted, and the population studied.
- The age figures describe maternal age only and do not incorporate the many other factors that modify risk.
- The calculator cannot account for individual medical history, previous losses, known chromosomal or uterine factors, or current symptoms.
- It has no diagnostic function whatsoever. Only clinical assessment and ultrasound can evaluate a specific pregnancy.
- Any bleeding or pain in pregnancy should be assessed by a clinician rather than interpreted against a statistical table.
Häufige Fragen
What is the risk of miscarriage by week?
Risk falls steeply through the first trimester. From a positive test the risk is roughly 1 in 5; once a heartbeat is seen at 6 weeks it commonly drops to around 10 percent, by 8 weeks to around 3 to 5 percent, and after 12 weeks to around 1 to 2 percent.
How does age affect miscarriage risk?
Risk rises from around 10 percent under 30 to around 20 percent at 35 to 39, around 40 percent at 40 to 44, and over 50 percent at 45 and above. The driver is the rising proportion of eggs with chromosomal abnormalities.
Did I do something to cause my miscarriage?
Almost certainly not. Ordinary activity, exercise, work, sex, lifting, stress and travel do not cause miscarriage. The large majority of first-trimester losses are chromosomal events determined at conception and were not preventable.
Does seeing a heartbeat mean the pregnancy is safe?
It substantially reduces the remaining risk but does not eliminate it. A heartbeat at 8 weeks is associated with a remaining risk commonly cited around 3 to 5 percent, compared with roughly 20 percent before any scan.
When should recurrent miscarriage be investigated?
Investigation is usually offered after two or three consecutive losses. It looks for chromosomal rearrangements, antiphospholipid syndrome, uterine abnormalities and thyroid disease. No cause is found in roughly half of cases, and the outlook for a future pregnancy remains good.
