Is ovaries retro peritoneal or peritoneal structure?

Ovaries are considered retroperitoneal structures, as they are located behind the peritoneum, which is the lining of the abdominal cavity. However, they are often discussed in the context of the peritoneal cavity because they are suspended within the broad ligament of the uterus and have a close relationship with the peritoneal space. Thus, while anatomically they are retroperitoneal, their functional association is with the peritoneal cavity.
