Write one function of the following:
Vas deferens
The male reproductive system includes a pair of testes, two sperm ducts, urethra, penis, and accessory glands.
Accessory glands: A few important accessory glands are associated with the male reproductive system. They secrete different fluids, which together with the sperms, form the semen. There are three types of accessory glands.
Vas deferens: The epididymis continues to form the vas deferens or the sperm duct, which opens at the top of the urethra. Through this duct, the sperms leave the testes and reach the urethra.
