From there, the sperm get mixed with nutrient-rich fluids from the seminal vesicles and a milky secretion from the prostate gland. This combination of sperm and fluids is called semen. The semen does three things: 1  Provides a watery environment in which the sperm cells can swim while outside the body.2  Provides nutrients for the sperm cells (fructose, amino acids and vitamin C). 3  Protects the sperm cells by neutralizing acids in the female's sexual tract.uring sexual intercourse, smooth muscles contract and propel mature sperm from the end portions of the epididymis through a long tube called the vas deferens, which is inside the body, just beneath the bladder.
The Male Reproductive System The main role of the male reproductive system is to make and deliver sperm. The testes are the main organs of the male system. Two testes are held in an external sac called the scrotum. The testes make sperm in tiny tubes called seminiferous tubules.The sperm mature and are stored in an epididymis. A tube called a vas deferens carries sperm from each testis to the urethra within the penis.Along the way, secretions of several glands form a nutrient-rich fluid called seminal fluid.he sperm mature and are stored in an epididymis.
