A unicornuate uterus is a type of congenital uterine anomaly where a woman has a uterus that is shaped like a banana, instead of the typical pear shape. This condition occurs when one side of the uterus fails to develop properly during fetal growth, resulting in a smaller, single-horned uterus. Women with a unicornuate uterus may experience various reproductive challenges, including difficulties in carrying a pregnancy to term, increased risk of miscarriage, and potential complications during delivery. Regular monitoring and medical care can help manage these risks for those affected.
