2. Reproductive System
 is the body system responsible for the production of new
individuals
 it is also the body system involved in sexual reproduction

3. Male
Reproductive
System

4. Male Reproductive System
FUNCTIONS:
 Produce male gametes
 Entrance of sperm into the
female’s vagina

5. Structure of the Male
Reproductive System
PARTS
 Testis
 Scrotum
 Penis
 Vas Deferens or
Ductus Deferens
 Urethra
GLANDS
 Seminal Vesicle
 Prostate Gland
 Bulbourethral
Gland

7. TESTIS
 Each testis is an oval structure about five cm
long and three cm in diameter
 Located in the scrotum
 It is the primary and most important structure
of the Male Reproductive System for it is the
one responsible for the secretion of sperm
cells.

8. SPERM
 Head
 Acrosome
 Centrioles
 Mitochondria
 Flagellum

9. VAS DEFERENS OR DUCTUS
DEFERENS
 A tube- like structure and carries the
sperm from the testis to urethra.

10. URETHRA
 It is the exit of urine and sperm out of the
body.

11. SCROTUM
 It is a sac of skin that holds the testis
 The scrotum contains the testes and is
divided into two internal compartments by
an incomplete connective tissue septum.

12. PENIS
 It is an external genital in the male
reproductive system that deposits sperm
into the vagina during mating.

13. SEMINAL VESICLE
 Glands posterior to the urinary
bladder.
 It secretes a fluid that makes up
most of the semen
It is the ejaculated fluid containing
sperm cells and secretions from other
glands

14. PROSTATE GLAND
 a firm, dense structure about the size
of a walnut that is located just
posterior to the urinary bladder.
 It secretes a slightly alkaline milky
fluid that is discharged as part of the
semen

15. BULBOURETHRAL GLAND
 Small, about the size of a pea, and
located near the base of the penis. A
short duct from each enters the
proximal end of the penile urethra.
 It secretes a thick and clear mucus
that lubricates and neutralizes any
trace of acidic urine in the urethra.

care of our
Reproductive
System?
