The uterus is one of key organs in reproduction and fetal development. A distorted shape and size of uterine cavity may to have significant impact on the reproductive failures (Chan et al., 2011; Saravelos et al., 2008). Current definitions and classification for uterine morphology and its congenital malformation are still controversial (Grimbizis et al., 2013; 2015; Ludwin and Ludwin, 2015a, b). This is an important barrier for studies evaluating the effectiveness of interventions for women with such conditions (Ludwin et al., 2015 a, b).
