Whether you can get pregnant with a uterine malformation depends on the type of uterine malformation. There are some types of uterine malformations that may make it difficult for you to hold on to your baby until full term. Type 1 of uterine malformation: uterine hypoplasia Uterine hypoplasia is extremely rare. This means that the uterus may be very small, or there may be no uterus at all. This condition is usually detected when a girl’s first menstrual period is late. It is impossible to get pregnant with this type of uterine anomaly. Type of uterine malformation 2: Bifid uterus A bifid uterus is one in which the uterus has two cavities, each leading to its own cervix and vagina, so a woman with a bifid uterus has two cervixes and two vaginas at the same time. Again, this type of uterine malformation is very rare. If you have a double uterus, it is possible to have a successful pregnancy. Type 3: Unicornuate Uterus A unicornuate uterus is only half the size of a normal uterus and has only one fallopian tube. This is a very rare type of uterine malformation caused by the uterus not developing properly during the initial stages of tissue formation. If you have a unicornuate uterus, you usually have only 1 fallopian tube attached. However, as long as the unicornuate uterus develops normally, it is entirely possible for you to have a successful pregnancy. Type 4 of uterine malformation: bicornuate uterus Instead of the normal pear shape, a bicornuate uterus resembles a heart shape with a deeper depression at the top of the uterus. This type of uterine malformation is called a bicornuate uterus because of its shape. A bicornuate uterus is a relatively common uterine malformation and should not affect your fertility either. However, if you are pregnant, there is less room for the fetus to develop compared to a normal uterus, so you are more likely to have a breech or premature birth. Type 5 of uterine malformation: longitudinal uterus A longitudinal uterus means that the uterine cavity is separated by a muscular or fibrous wall called the diaphragm. This septum may be only part of the length of the uterine cavity, a condition known as “incomplete mediastinum,” or it may extend all the way from the base of the uterus to the cervix, a condition known as “complete mediastinum. Incomplete mediastinum is more common than complete mediastinum. In rare cases, mediastinum may lead to infertility. Saddle-shaped uterus looks more like a normal uterus, except that it has a slight indentation at the top. Saddle uterus is classified as mild, moderate or severe. Mild and moderate usually do not make conception or pregnancy difficult.
