Can pregnant woman with bicornuate uterus?

The complete absence of fusion of the two Mullerian ducts (the embryonic structure that will determine the formation of the female genitals) can result in complete duplication of the vagina, cervix and uterus. A partial defect of the merger may result in a single vagina with a solitary or duplicated cervix and a complete or partial duplication of the cervix, so it can form a persistent uterine septum to a greater or lesser degree, with the outer appearance of a single uterus (bicornuate or septate uterus) The septum may be completely and totally divide the uterine cavity and cervix into two equal parts.

While some of the uterine abnormalities cause infertility, the vast majority of patients are fertile. Undoubtedly the uterine abnormalities may be associated with completely normal reproduction. However, the overall incidence of spontaneous abortions, premature birth, stillbirth, abnormal presentation of the product at delivery and caesarean sections are clearly increased in the presence of uterine anomalies. Unfortunately it is impossible to predict which are the patients who had these difficulties.

It is considered that the presence of a septum located in the middle of the uterine cavity could lead to abortion because of the reduced space available for intrauterine fetal growth or because of implantation of the placenta in a partition with poor blood supply (or septate uterus bicornuate)

Considering the different types of abnormalities of the uterus, it is likely that the percentage of term pregnancies is of 5 to 10%, whereas in patients with surgical correction of the percentage increases to 80 to 90%.

Most patients evaluated for infertility or repeated abortions show a septate or bicornuate uterus and fetal survival rates are higher after repair of this disorder in relation to other uterine abnormalities. Also there have been a higher incidence of menstrual cramps and heavy menstrual periods and abnormal in patients with any type of uterine malformation, they improve or disappear after corrective surgery.
