Makes fluid that protects the sperm

The infusion of a high dose of a recombinant form of human epidermal growth factor to cynomolgus monkeys for two weeks was reported to induce hyperplasia of the epithelium lining the epididymis. The seminal vesicles, two saclike structures, sit close behind the bladder and extend toward the bladder. After encountering the oocyte, sperm next have to penetrate the outer corona radiata and zona pellucida layers of the oocyte. The vesicles secrete a whitish-brown fluid containing sugars, prostaglandins, and other substances that makes up two-thirds of the semen volume. Dogs treated with experimental aminopyrimidine inhibitors of oxidosqualene cyclase also produced sperm granulomas.

However, few of these studies have conclusively identified the epididymis as a testis-independent target. It takes about 28 days. The role of the epididymis in modification of the sperm membrane and the maturation of sperm function is incompletely understood, but the potential for chemicals to enter the epididymal fluid and produce direct effects on the sperm has been demonstrated. Semen contains sperm, the male reproductive gametes, along with a number of chemicals suspended in a liquid medium. The spermatic cords contain the ductus deferens along with nerves, veins, arteries, and lymphatic vessels that support the function of the testes. Contain proteins, enzymes, fructose, mucus, vitamin C, flavins, phosphorylcholine and prostaglandins. The epididymis is made up of several feet of long, thin tubules that are tightly coiled into a small mass.
