Male Reproductive System

s

Seminal Vesicle,

Prostate Gland,

and Cowper’s Gland

are all active in producing fluids which serve as

nourishment for the sperm and lubrication for the duct.

“ The fluids secreted by this glands and the

sperm form the fluid called semen ”.

“ From the epididymis, the

sperm cells travel through

another tube, called vas deferens

“.

it receives sperm cells, carries them up, and

delivers them into the urethra.

Vas Deferens

Epididymis

it is a very long, coiled tube where the sperm

cells travel when they’re undergo maturation.

Testes

the main organ of the male reproductive system;

pair of spherical glands located in a pouch that

hangs outside of a male’s body;

at puberty, it produce sperm and male sex hormone

called testosterone.

s

Urethra

it is a tube that runs through the penis;

the passageway for urine and sperm that leave the

male’s body.

“ The passage of semen through the

urethra occurs by a process called

ejaculation “.

Penis the male organ of copulation;

covered by a fold of skin called

foreskin;

it’s tip is called glans.

“ The foreskin may be removed when the

baby is born or during adolescence. This is called

circumcision“.

A boy may experience a

discharge of semen while asleep. This

is known as wet dreams. Having wet

dreams is normal for boys undergoing

adolescence.

Female Reproductive System

Ovary

the main organ of the female

reproductive system

oval in shape and located in the

lower part of the abdomen

produce the female sex cells

called eggs or ova and likewise

secrete the female sex hormones,

estrogen and progesterone

these hormones are responsible for the development

of female secondary characteristics, such as the

development of the breasts, broadened pelvis, and

female pattern of fat distribution.

they also play a large role in the menstrual cycle.

Estrogen and Progesterone

At birth, the eggs are

already formed in the ovaries.

These immature eggs are

enclosed in the follicles.

A follicle is a bubble- like

structure that stores and

protects the eggs until they

mature at puberty.

When a girl reaches

puberty at ages 11-14, a fully

developed egg is released from

either of the ovaries. This

process is called ovulation.

A female have three outside

openings between the legs.

These openings are the:

vagina

urethra

anus

Vagina

is also known as birth canal

it is between the anus and

urethra

it is a 3 to 4 inch passageway or

canal inside the female

it is protected by folds of skin

known as the vulva

Cervix

found in the

interior end of the

vagina

a short canal

which leads to the

uterus

Uterus

is where the baby

develops and not in

the stomach as some

people think

Fallopian tube

the passageway that

conveys the ovum to the

uterus

“As the ovum moves

along the fallopian tube,

fertilization or the union of

the egg and sperm can

happen”.

Adolescence

Adolescence is the time between

childhood and adulthood. This is often

referred to as the teenage years. The onset of

puberty generally marks the beginning of

adolescence. Puberty is the state of physical

development marking the beginning of one’s

reproductive cycle, which means a girl or a

boy is capable of producing children.

When a girl reaches puberty, one egg

matures around every 28 days. Each time an

egg in ovary matures, the wall of the womb or

uterus, called the endometrium becomes thick

and spongy with many blood vessels, in

preparation for the arrival of the fertilized egg.

If the

egg is not fertilized because there is no contact

with sperm, the egg dies. The thickened lining

of the uterus breaks up and comes out with

blood through the birth canal or vagina. The

process is called menstruation.

Menstrual Cycle

The onset of the first menstruation

called menarche happens at different

times among girls. Some girls start at an

early age of 11 while others start to

menstruate at an older age of 16. a woman

stops having menstrual periods around the

age of 45-55. this is the stage of life called

menopause.

For some girls, menstruation is

accompanied with cramps or pain and

some discomfort in the lower back and

abdomen. This discomfort is known as

dysmenorrhea. This may be alleviated

with exercise and proper diet.

development marking the beginning of

one’s reproductive cycle?

reproductive system that is a muscular sac

below the penis that encloses the two testes?
