What Causes Double Uterus?
Uterine didelphys is a congenital condition, which means it’s present before birth.
The uterus develops from two small tubes called Mullerian ducts, the early structure that develops into the female reproductive organ. Typically, the Mullerian ducts fuse, forming a large hollow organ – the uterus.
With uterine didelphys, however, the Mullerian ducts don’t join together. Instead, each develops into a separate womb.
Now, a double uterus may have just one opening (cervix) into one vagina, or each has a separate cervix. In many cases, a thin tissue runs through the vagina, separating it into two openings.
The exact reason uterine didelphys happens is still unknown, but doctors believe genetics may be a factor as the condition sometimes runs within families.
