What are the 3 paired ducts?
The 3 paired ducts refers to the ducts that form during kidney and gonad differentiation. The mesonephric ducts (= Wolffian) form first in association with the intermediate kidney (mesonephros) and connect to the urogenital sinus region that will form the primitive bladder. These ducts form in both male and female embryos and a lateral branch from these ducts form the nephric ducts. The nephric ducts that will eventually form the ureters, connecting the final kidney (metanephros) with the bladder. The paramesonephric ducts (= Mllerian) form beside (hence “para”) the mesonephric ducts and their further development is inhibited in the male, continues in the female to form the uterus.
