Recent research suggests the rete ovarii (RO), a network of tubules near the ovary, plays a crucial role in the female reproductive system. Once considered a vestigial structure, a new mouse study indicates the RO actively supports the ovary's environment and may have a hormonal function.
The RO is located where blood vessels and nerves enter the ovary. Its similar form across mammals suggests its importance. Researchers at the University of Michigan conducted experiments on mice, observing RO development and analyzing tissues in adult specimens.
Anatomist Adam Taylor suggests, "Rete ovarii may maintain the stability of the internal environment of the ovary and even perform a hormonal role." These findings could lead to new gynecological disease treatments by understanding the RO's function in endocrine regulation and reproductive health. The study was published in the journal eLife.
