Mesonephric wolffian duct
WebTwo ducts closely related to the developing urinary system are called mesonephric, or wolffian, ducts. In males, each mesonephric duct becomes differentiated into four related structures: a duct of the epididymis, a ductus deferens, an ejaculatory duct, and a seminal vesicle (see below). In females, the mesonephric ducts are largely suppressed. WebParamesonephric ducts (or Müllerian ducts) are paired ducts of the embryo that run down the lateral sides of the genital ridge and terminate at the sinus tubercle in the primitive urogenital sinus. In the female, they will develop to form the fallopian tubes, uterus, cervix, and the upper one-third of the vagina. Development [ edit]
