Male Sexual Organs: Understanding and Loving your Body
The male reproductive system contains several structures.
- Testicles (Testes)
- Vas Deferens
- Seminal Vesicles
- Prostate Gland
The penis is comprised of three main parts, each having its own responsibilities. The three main parts include the glans, body, and root penis. The glans, made of corpus spongiosum tissue, is located at the head of the penis. The body contains two specific types of tissues: corpus cavernosa and corpus spongiosum. The corpus cavernosa are paired on each side of the penis and are responsible for the male erection when filled with blood. The corpus spongiousm runs the center of the penis protecting the urethra. The root of the penis is responsible for attachment to the abdominal wall. The penis is covered by a foreskin that may be removed through the process known as circumcision.
The testicles are two oval shaped bodies located inside the scrotum. The testes are responsible for the production of sperm and contribute to the production of the hormone, testosterone. The production of sperm is necessary for procreation. The production of testosterone is necessary for proper development and maturation. It is mainly noted responsible for deepening of the voice, muscle development, and the growth of body hair.
The scrotum is comprised of thin skin and muscle, responsible for the protection and the temperature regulation of the testicles. The scrotum is located outside the body. This is a necessity, as the optimum temperature for the development of sperm is lower than body temperature. The scrotum contains cremasteric muscles.
The epididymus is a tube located on each testicle responsible for the movement of sperm out of the scrotum, away from the testicles to the vas deferens.
The vas deferens is connected to the epididymis, and is the storage site for sperm produced by the testicles. The vas deferens is also connected to the seminal vesicles, creating the ejaculatory duct.
The seminal vesicles are glands, responsible for the production of a fluid that provides the sperm with necessary nutrition and lubricates the urethra. This fluid, mixed in addition to other fluids, is known as semen when ejected from the body.
The urethra is a sexually explicit gland located only in men. It is the tube that runs through the center of the penis (corpus spongiosum) has two main responsibilities. The first is the transportation of urine from the bladder out the glans of the penis. The second is the transportation of semen, comprised of fluids and sperm, from the ejaculatory duct (comprised of the seminal vesicles and prostate), out the glans of the penis.
The prostate gland is located below the urinary bladder surrounding the urethra. It is responsible for the production of prostatic fluid. This fluid contains the necessary nutrients for the support of optimum sperm health and serves as protection for the sperm. Prostatic fluid is the main component of semen.
