Left or right which uterine Horn consists foetus?

In a bicornuate uterus, where the uterus has two horns, the presence of a fetus can occur in either the left or right horn, depending on the specific case. The side that contains the fetus is determined by various factors, including the position of the embryo during implantation. It's important to assess each individual case through ultrasound or other imaging techniques to identify the location of the developing fetus.
