Prevalence of Uterine Malformations in Newly Married Unselected Population

Uterine malformation is occur due to the abnormal development of Mullerian canal during embryogenesis and it is known that it reduces the fertility and live birth rate and also increases the abortion and preterm birth rate. There are different classification methods have been used for defining the uterine malformations. The most common used classification method in the World is American Society of Reproductive Medicine (ASRM)'s system. In addition European Society of Human Reproduction and Embryology (ESHRE) and European Society for Gynaecological Endoscopy (ESGE) developed a new classification system. ASRM Uterine malformation Classification which is used for diagnosis and treatment of uterine malformations in our clinic is subdivided into 7 titles:

1. Agenesis or Hypoplasia -(a. Vaginal b. Cervical c. Fundal d. Tubal e. Combine)
2. Unicornuate -(a. Communicating Horn b. Non-Communicating Horn c. No Cavity d. No Horn)
3. Uterus Didelphus
4. Bicornuate Uterus-(a. Complete b. Partial)
5. Uterine Septum- (a. Complete b. Partial)
6. Arcuate Uterus
7. Diethylstilboestrol (DES) Related

The diagnosis of some of the uterine malformations have been done by using two dimensional (2D) ultrasonography, hysterosalphingography or surgically (laparoscopy or laparotomy) traditionally. A non-invasive procedure is required for the diagnosis of the uterine malformation, which is evaluating both the uterine contour and endometrial cavity.

In recent years frequently used three dimensional (3D) ultrasound is a non-invasive and quick diagnostic technique, and also it is sensitive as MRI. In hospital based case control studies, the frequency of uterine malformation was generally around 6%, while it was 8% in infertile patients and 12% in patients with abortion. However, there is a lack of prospective studies investigating the prevalence of uterine anomalies, fertility potential and effects on pregnancy outcomes in unselected patient groups in the literature. Therefore, at the high level evidence, there is no evidence that these anomalies affect fertility and pregnancy outcomes and should be corrected. In this study it was aimed to investigate the effects of uterine malformations on fecundability and pregnancy outcomes by evaluating the uterine morphology with 3D ultrasonography and calling for control purposes at the 1st and 2nd years of newly married women between the ages of 18-40.
