The infantile uterus is a congenital abnormality of the female genital tract included in the U1 group of the European Society of Reproduction and Embryology (ESHRE) and the European Society of Gynaecological Endoscopy (ESGE). This group to which it belongs is called the dysmorphic uterus and. More precisely, the infantile uterus, is defined as a uterus with a narrow but not thickened uterine cavity of the lateral walls and a 1/3 correlation of uterine body and 2/3 of cervix.
It can be differenciated from the hypoplastic uterus or "naïve uterus" which would include those cases of smaller uterus.
In either case, the chances of gestation remain intact because in the case of the infantile uterus of the ESHRE/ESGE classification, the uterine cavity is configured by a healthy tissue without areas of fibrosis, and because in the case of the hypoplastic uterus, this should be considered a variant of normality.
