Also seen, at right, is the development of an egg cell (ovum) from follicle to embryo.

Congenital anatomic deformities of the uterus can contribute to infertility by causing recurrent miscarriages. While the specific mechanisms by which these structural variations lead to pregnancy loss are complex, they generally involve anomalies in the development of the uterine cavity, such as incomplete development or duplication of the organ.12

These structural irregularities may interfere with the normal implantation of a fertilized egg or disrupt the environment necessary for the fetus to develop successfully throughout the pregnancy. Because the uterus is the essential site for fetal growth, any significant congenital deviation from its typical anatomy can compromise its ability to support a pregnancy to term, thereby increasing the risk of consecutive pregnancy losses.31

If you are concerned about recurrent miscarriages, it is important to consult with a medical professional to discuss diagnostic options and potential treatments.
