Uterine malformations are the result of abnormal development of the Müllerian ducts (those responsible for the formation of the female reproductive system) during a woman's prenatal development and can affect fertility.
Approximately 1% of women have uterine malformations, however, only 25% of these patients have reproductive problems.
Alterations that occur during the process of development and fusion of the Müllerian ducts give rise to uterine or Müllerian malformations.
