A septum refers to a thickened wall or partition that can form within the ovarian tissue, dividing it into separate compartments or cysts. These septa can occur as a result of various conditions and can affect the structure and function of the ovary. The presence of septa in the ovary may impact fertility and can be associated with conditions such as polycystic ovary syndrome (PCOS) or certain ovarian cysts. Accurate diagnosis and management of ovarian septa are important for understanding and addressing potential reproductive health concerns.
