Malformations utérines et infertilité

The effective incidence of uterine malformations is not clearly defined in the literature. If minor uterine abnormalities are considered, this incidence is about 6-7 % among the normal fertile population and >25 % in women with recurrent miscarriages. Nevertheless, major malformations are observed in only 0.5% to 5% of the general population, in 0.1% to 3% of fertile women, in 3% of infertile women and in 5-10 % of women with recurrent miscarriage. The most frequently encountered uterine malformations are bicornuate and septate uteri. The diagnosis is confirmed by both hysterosalpingography and endoscopy (hysteroscopy and laparoscopy). Hysteroscopic metroplasty is commonly used to repair uterine septa and enlarge T-shaped uterus in women exposed in utero to deithylstilbestrol.
