1. MALE REPRODUCTIVE
SYSTEM
MALE REPRODUCTIVE
SYSTEM

2. Male Reproductive System
Major Function: Makes sperm cells (gametes)
which can fertilize female gametes to produce a
zygote.

3. GENITAL SYSTEM
Gonads
- Genital ridges,
- Germ cells,
- Primitive sex cords.
Testis
- Rete testis,
- Tunica albuginea,
- Sertoli cells, leydig cells.
Seminiferous tubules
Ductus deferens

4. Scrotum
•A pouch of skin
that hangs from
the body below the
pelvic cavity.
•Contains two
testes and their
associated ducts.

5. Scrotum
•The scrotum has a temperature of
about 93.2F (the rest of the body is
usually 98.6F)
•Sperm formation
occurs most rapidly
at this cooler temp.

6. Scrotum
•Two muscles (the cremaster and the
dartos) pull the scrotum close to the
body when it is cold and relax when it
is warm.

7. Testes
The primary reproductive organs of the
male reproductive system.

8. Seminiferous Tubules
Sperm is
manufactured in a
network of tubules
called seminiferous
tubules

9. Epididymis
The epididymis holds the testes in place
and connects the testes to the Vas
Deferens.

10. Vas Deferens
Drains the testes and epididymis, carrying
sperm to the pelvic cavity.

11. Quick Check
Simon Says…

12. Penis
The penis delivers sperm into the
female reproductive tract.

13. Glans
The enlarged end of the penis.

14. Prepuce
Loose foreskin that covers the glans
penis.

15. Penis
The shaft of the penis is composed of
erectile tissue and the urethra.
The opening is called the
External urethral orifice.

17. MALE GENITAL DEFECTS
Hypospadias
Epispadias
Extrophy of Bladder
Micropenis & Bifid penis

18. DESCENT OF TESTIS
 Urogenital mesentery
 Gubernaculum
 Processus Vaginalis
 Inguinal canal
 Tunica Vaginalis
 Testicular layers

19. AGENESIS OF EXTERNAL GENITALIA

20. DEFECTS IN SEX
DIFFERENTIATION
Klinefelter Syndrome
Gonadal dysgenesis
Hermaphrodites
Pseudohermaphrodites
