[2] It is recognised in the ESHRE/ESGE classification,[3] and is associated with failed implantation, increased risk of ectopic pregnancy, miscarriage and preterm delivery.

[5] Women are often diagnosed with this condition after several failed pregnancies, proceeded by exploratory diagnostic procedures, such as magnetic resonance, sonography, and particularly hysterosalpingography.

[6][7][8] In such studies, a widening of the interstitial and isthmus of uterine tube is observed, as well as constrictions or narrowing of the uterus as a whole, especially the lower and lateral portions, hence the "t" denomination.

However, they carry a greater risk of complications, such as miscarriages, reduced fertility and preterm births, both before and after any treatment.

[10][11] The current surgical procedure to treat this malformation, termed a hysteroscopic correction or metroplasty, is undertaken by performing a lateral incision of the uterine walls, and can return the organ to a normal morphology, while improving the patient's former reproductive performance.
