Precautions for Bicornuate Uterus Pregnancy

What a heart-shaped uterus is at all, how and why it develops and how it affects the pregnancy, you will learn in our article.

Heart-shaped uterus – what exactly is that?

The uterus is a hollow organ, also known as the uterus. This organ serves as the venue for the fertilized egg cell. The standard form of the womb may therefore also depend on factors such as the fertility of a woman and the risk of miscarriage or premature birth.

You can find the uterus in the pelvic area. It has the shape of an upside-down pear and is about 7 cm long on average for a woman who has not yet had a baby. In a woman who has already had one or more births, the uterus may have an average length of 8 cm. The upper part of the uterus is called fundus, the lower part cervix. The cervix – also cervix – points towards the vagina.

A small percentage of women have a uterus that does not meet the norm. Then there is the talk of a uterine anomaly. It is estimated that between one and 3.3 percent of all women have a uterine anomaly. Exact numbers are not known because many women do not see that you have such an anomaly. The uterus arcuatus is one such malformation, but the least developed. Here you can find a dent in the upper part of the uterus.

Causes of uterine anomalies

The development of the uterus starts already in the embryonic phase. From the so-called Müller-Gänge, part of the genitals develops in the embryonic phase in girls and boys. In girls, the fallopian tubes, the uterus and the vagina arise from the Müller aisles.

These passages are created in the trunk area of the embryo. In the course of development, both Müller’s ducts grow together and eventually form a hollow organ, the uterus. Most malformations of the uterus are caused by the fact that the merging of the two Mueller courses does not proceed correctly.

In many uterine anomalies, therefore, a division of the uterus can be seen. The heart-shaped uterus is largely similar to a normally developed uterus and is only slightly “dented.” This is the mildest form of uterine anomaly.

Abnormalities of the uterus may have genetic causes or arise when embryonic development has been disrupted. Medications that mothers have taken from pregnant women during pregnancy can promote a malformation of this organ.

Pregnancy in a heart-shaped uterus

If there is a uterine anomaly, there is often the possibility of therapy in the form of a surgical procedure. In the case of a heart-shaped uterus, such an intervention is usually only recommended if there is a habitual abortion (repeated miscarriage).

In medicine, the impact of a heart-shaped uterus on the fertility of a woman and the risk of miscarriage or premature birth is discussed very controversially. Some experts see in it only a slight modification of the normal form without significant limitations of fertility. Others feel that there may be more problems during the performance.

Get advice from your doctor or health professional on how to detect premature labor and avoid prematurely or miscarriage. It is important that you
perform all checkups.

Ask your doctor for advice

Uterine malformations affect very few women. If you have already had a premature or miscarriage and the cause is not clear, talk to your doctor about uterine anomalies. Your doctor can examine your uterus and, for example, by hysteroscopy (this is a uterus mirroring performed by an endoscope), 3D ultrasound, ultrasound with filling the uterus (in this case, the interior of the uterus is filled with a liquid to detect any malformations better can) or MRI (Magnetic Resonance Imaging) determine if an abnormality of the uterus could be causally involved.


  • The heart-shaped uterus is the slightest form of uterine malformations
  • In the uterus arcuatus, the upper wall of the uterus is dented only slightly
  • Uterine anomalies are congenital and develop during the embryonic developmental phase
  • Pregnancy is possible, but those affected should seek medical attention and take care of all medical check-ups
