3. Functions of male reproductive organs
Testes
produce sperm and manufacture the male sex hormone, testosterone.
Epididymis
Sperm storage and maturation
Vas deferens
transports sperm from the epididymis to the seminal vesicles.
ATAR & general

4. Functions of male reproductive organs
Seminal vesicle, prostate gland & Cowper’s gland
secrete fluids that form part of the semen.
Urethra
carries semen and urine through the penis to the outside.
Penis
the external male organ which introduces semen into the female vagina and through which urine passes during urination.

10. Functions of female reproductive organs
Ovaries
produce ova (eggs) and manufacture the female sex hormones, estrogen and progesterone.
Fallopian tube
transports ova to the uterus. Generally the site of fertilisation.
Uterus
houses and nourishes the fetus during pregnancy.
Vagina
the female organ of sexual intercourse, where the sperm are deposited. It also serves as the birth canal.
