testicles; epididymis, vas deferens, urethra, fluid, urethra
cervix, uterus, fallopian tubes, egg cell
Allows passage of urine and semen Provides sensation (has many nerve endings)
PENIS (made up of shaft, glans, and foreskin)
Protects the glans of the penis Provides sensation
Males who have been circumcised don’t have one
FORESKIN
Muscular sac which is shorter when cold, longer when warm Holds testes Controls temperature
Provides sensation
SCROTUM
Produces sperm and sex hormones (androgens and testosterone)Each is made of 500–1,200 feet of tightly coiled tubes
TESTES (also called
testicles)
Allows maturation of sperm
EPIDIDYMIS
Cell from a man called sperm
Sperm carry the strings of genes (called chromosomes) or DNA instructions in case the sperm meets with an egg cell and
SPERMATOZOA (sperm)
Suspends the testicles
Supply blood to the testicles
Provide sensation
Carry sperm from the testicles
SPERMATIC CORDS
Provides storage for sperm
Allow passage of sperm
Provides sensation
Carries sperm from the testes
VAS DEFERENS
Contributes fructose (sugar) to semen for nourishing these perm
SEMINAL VESICLES
Helps sperm live longer and travel better
About a teaspoon per ejaculation Contains hundreds ofmillionsof sperm
SEMEN
Produces most of the fluid that makes up semen
PROSTATE GLAND
Pair of glands
Produces pre-ejaculatory fluid (called “pre–cum”) that cleans the urethra to protect sperm. Some pre-ejaculatory fluid may contain sperm
COWPER’S GLAND (also
called bulbourethral
glands)
