GROWTH AND
DEVELOPMENT
Anatomy and Physiology
Male Reproductive
System
3 Glands to Make Semen
Seminal Vessicle: Adds FRUCTOSE to sperm
Prostate Gland: Common site of cancer in
males over 50. PSA test to detect cancer
early. Adds alkaline fluid to sperm
Cowper’s Gland (Bulborethral Gland): Preejaculatory fluid to clean urethra. Adds more
alkaline fluid to sperm.
Urethra and Vas
Deferens
Urethra: Passageway for urine and semen
Vas Deferens: Passageway for sperm
SPERM: Male sex cell
OVUM: Female Sex Cell
TESTES and SCROTUM
Testes: Produce and Store Sperm and
produce Testosterone
Scrotum: Holds the testes in place, protects
the testes and controls the temperature of the
sperm
Penis
Male Sex Organ
Erectile Tissue that allows it to grow in size
and become erect
SPERM and SEMEN
Sperm
microscopic and mobile
150 million- 300 million are ejaculated in
about a tablespoon of semen
with its X & Y chromosomes, determines
the gender of the baby
SEMEN= sperm + fructose + alkaline fluid +
alkaline fluid
SPERMATOGENESIS
When a male first begins producing sperm
Usually between the ages of 11-15
Males produce sperm from spermatogenesis
until death
