Which part is responsible for delivering sperm?
The epididymis sits directly on top of each testis. Sperm from the testis mature as they move through the coiled duct of the epididymis. During sexual intercourse and ejaculation, they are expelled into the vas deferens. The vas deferens pushes the sperm up over the bladder and down toward the prostate gland.
Which male organ is responsible for producing the sperm?
testes
Testicles (testes) The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm.
What is the male sex organ and passageway of sperm and urine?
Urethra. The urethra extends from the urinary bladder to the external urethral orifice at the tip of the penis. It is a passageway for sperm and fluids from the reproductive system and urine from the urinary system.
How semen is produced?
When a man is stimulated for sexual activity, the sperm are mixed with seminal fluid — a whitish liquid produced by the seminal vesicles and the prostate gland — to form semen. As a result of the stimulation, the semen, which contains up to 500 million sperm, is pushed out of the penis (ejaculated) through the urethra.
