Functions of the Male Reproductive system

• To produce, maintain and transport sperm and protective fluid (semen)

• To discharge sperm within the female reproductive tract (vagina).

• To produce and secrete male sex hormones (testosterone).

ROAD MAP OF THE MALE REPRODUCTIVE SYSTEM

Testicular Cancer

Testicular Cancer:

• Most common in ages 15-35

1. Undescended testes as child

2. Genetic link

• Look for unusual lumps, swelling, feeling of heaviness, pain, and discomfort in scrotum or abdomen

What is SPERM?• Sperm is the Male

Sex Cell

• The head of the sperm contains the DNA, which when combined with the egg's DNA, will create a new individual

What is Semen?

• Semen is made up of sperm and seminal fluid.

• As the sperm travels through the male reproductive system the seminal vesicles, prostate and bulbouretheral glands provide fluid that nourish and protect the sperm

Return to Previous Slide

Testes and Scrotum

Testes:• Make sperm

• Produce testosterone• Main sex hormone

of males

Scrotum:• Skin-covered sac

that hangs from the body

• Lower temperature than body for sperm production

Return to Previous Slide

Epididymis

Epididymis:• Coiled tube where

sperm mature and are stored

• 2-10 days to mature

Return to Previous Slide

Vas Deferens

Vas Deferens:• Tubes the sperm

pass through to get fluids added (semen)

• Vasectomy- a health care provider closes or blocks the tubes that carry sperm.

Return to Previous Slide

Bladder• It is a muscular sac in

the pelvis,

• The bladder stores urine, allowing urination to be infrequent and voluntary.

Return to Previous Slide

Seminal Vesicle• The seminal vesicles

are a pair of tube-like glands.

• Found behind the bladder of males.

• They make most of the content of semen

Return to Previous Slide

Penis

Penis:

1. Removes urine from body

2. Delivers sperm to the female

Changes:• Erection:

• Blood vessels fill with blood

• Ejaculation:• Sperm released

from the penis after arousal

• Nocturnal Emissions

Return to Previous Slide

Prostate Gland• Walnut-sized gland• Secretes fluid that

nourishes and protects sperm.

• During ejaculation, the prostate squeezes this fluid into the urethra, and it’s expelled with sperm as semen.

Return to Previous Slide

Urethra• Carries urine from

bladder to outside of body

• In MALES it also releases sperm/ semen when penis is erect

• When the penis is erect, urine is blocked from the bladder

Return to Previous Slide

Testosterone• Principle Male Sex Hormone and anabolic steroid• Promote tissue growth of testes and prostate gland• Also promotes sexual characteristics increase muscle,

bone mass, & body hair growth.
