Male Reproductive System
Side view
 The purpose of the organs of
the male reproductive
system is to perform the
following functions:
 To produce, maintain, and
transport sperm (the male
reproductive cells) and
protective fluid (semen)
 To discharge sperm within
the female reproductive tract
during sex
 To produce and secrete male
sex hormones responsible
for maintaining the male
reproductive system
Male Reproductive organ
Parts and functions
 Erectile tissue: fills with blood

for arousal for penetration in
sexual intercourse
Epididymis: holds sperm
during maturation.
Testis: sperm is produced
Vas deferens: sperm duct;
pathway for sperm
Urethra: passage way for urine
and semen
Seminal vesicle: gives sugar
and protein fluid to make
semen
Prostate gland: produces the
liquid texture for semen
Sperm cell
Sperm cell
 Acrosome: enzyme found at
the tip of the head of the
sperm cell which helps in
breaking down the jelly coat of
the egg cell to fertilize the egg.

Sexual intercourse
 Copulation: sexual intercourse: when a man becomes
sexually excited, the penis becomes erect and stiff. This is
due to an increase in blood pressure in the erectile tissue
spaces surrounding the urethra. The penis is inserted into
the vagina of the woman and movement causes
Ejaculation of semen into the vagina.
 Ejaculation: is brought about by contraction of the muscle
surrounding the urethra. This expels semen through the
urethra into the vagina.
Fertilization
 Fertilization: The Fusion of sperm nucleus with the
nucleus of the ovum/ova which occurs within the
oviduct.
Implantation
 Implantation: When the fertlize egg (zygote) divides into a
ball of cells called a blastocyst and sinks into the wall of
the uterus and develops into an embryo.

contraction at birth, protects
fetus
Amnion: membrane enclosing
fluid, protecting fetus from
shock and allowing
movement.
Umbilical cord: carries
nutrients in vein and waste in
artery.
Placenta: contains villi, formed
from fetus and mother, act as
a barrier for blood , bacteria
Villi: large surface
Birth
Birth stages
 stage1: contraction of muscles of the uterus. Labour starts; to
push out the baby. This is possible because of a hormone called
oxytocin which starts contractions.
 Stage2: increasing contractions of the uterine muscle push the
baby through the cervix and then the vagina.
 Stage 3: finally the baby is expelled head first.
 After birth: the umbilical cord is cut and tied so that the remains
from the navel on the abdomen. The placenta and membranes
are shed from the mother and are called afterbirth.
