Explanation:
Sperm is the male reproductive gamete produced by the testes. During copulation or sexual intercourse, the produced sperm moves along a tube called VAS DEFERENS or sperm duct. The sperm mixes up with fluid called SEMINAL FLUID produced in the accessory glands comprising of seminal vesicles, prostrate gland and the bulbourethral glands to form the SEMEN, which is ejected from the urethra (a tube that runs from the bladder to the penis) during ejaculation.
The seminal fluid that mixes up with the sperm serves to lubricate it for easy locomotion within the female reproductive parts and also provide nourishment for the sperm.
