Any abnormal development in a woman's uterus causes not only physiological effects but also causes infertility. There are many different types of uterine malformations.

Most women with uterine malformations have no difficulty getting pregnant and have normal pregnancy outcomes. However, uterine malformations are often found in women who are infertile and have recurrent miscarriages and premature births.

A hydatidiform uterus is a mild variant of the shape of the uterus and is one of the abnormalities of the Müllerian ducts. However, a hydatidiform uterus is unlikely to affect fertility.

Unicornuate uterus is a type of Müllerian tubal malformation (class II) characterized by a banana-shaped uterus leading to a single fallopian tube.

Female genital malformation is a condition in which the genitals are structurally abnormal. The cause is due to the genitals having a disorder in the differentiation process when they are still fetuses. Female genital malformations are often found in organs such as the fallopian tubes, uterus, vagina, etc. and can cause difficulties in sexual intercourse or reproduction in women.
