male anatomy in MODESTO.In women the in most of the key organs are internal.
Looking at the figure below you can see the major components of the male reproductive system.
The testis is the organ in men where sperm are produced and where testosterone, the primary male sex hormone is produced.
The testes are located in a sac that hangs from the outside of the males body between the base of the penis and the anus.
This area in both men and women is called the.
The testes are outside the body because the production of sperm, called spermatogenesis, functions best when the temperature of the testes is slightly lower than the temperature of the rest of the body.
By being outside the main structure of the body the testes remain somewhat cooler.
You may notice that in cold weather the muscles of the scrotum contract drawing the testes up close to the body, and when it is warm the muscles relax allowing the testes to hand lower away from the body.
Inside the testis are millions of tiny tubules that sperm are released into in an immature state.
The immature sperm travel through these tiny tubules which join together like the branches of a tree to become bigger and bigger until they come to an organ on the back of the testis called the epididymis.
In the epididymis the tubules further come together until out of the bottom of the epididymis comes a single muscular tube called the vas deferens.
The vas deferens then travels up through the scrotum, through a canal in the groin called the inguinal canal inside the body.
Sperm are stored in a pouch off the vas deferens called the seminal vesicle for a few weeks while they mature.
The penis is made up of special tissue that has the capacity to fill with blood and become larger and firmer, called or an erection.
There are three major parts to the penis.
They become filled with blood with sexual excitement when the outflow of blood from these areas is constricted, and provide much of the rigidity and size increase of the erect penis.
This also becomes engorged with an erection, but is less rigid, and tends to be the part of the penis with the most sensation.
The prostate is an organ inside the male that the urethra passes through and lies between the bladder and the penis.
It also lies just in front of the rectum.
It serves primarily to provide fluids for the sperm to be diluted into.
This fluid, sperm, and the fluids combined is called semen, or seminal fluid.
Boys often wonder about their genitalia.
Every person looks somewhat different.
Their noses, ears, hands, feet, hair etc are all somewhat different.
This variability is also seen in the genitalia.
One of the biggest concerns of many boys and young men is the size of their penis.
