why a man in their 20's should learn about the reproductive system???
It is very important to know ones body and how it functions and a man in theier 20's may be using their system alot. it is also important to learn what your partner is going through with menstration and contraception issues ( see later page). so it really is important to be educated in this topic and you never know you might learn something new that will affect your life or it might improve your relationshipas now you will be able to know what your partner is going through.....
The Reproductive systems
The male and female reproductive systems are designed to create new life. Eggs are made in the female's ovaries, and sperm in the male's testicles. The ovaries and testicles also make sex hormones. New life begins when an egg from a woman is fertilised by sperm from a man. Eggs are made in the ovaries, and sperm in the testicles. The ovaries and testicles (gonads) also make sex hormones.

The female Reproductive system
The female reproductive system is made up
of the vagina, womb (uterus), fallopian tubes and ovaries. their sex cell is called an egg or an ovum.
Vagina – a muscular
canal around 7.5 cm long that extends from the neck of the womb to the genitals,
or vulva.
Uterus (womb) – a muscular organ, shaped
like an upside down pear. Its lining is called the endometrium. The neck, or
entrance to the womb is the cervix, which has a small hole in its centre,
called the os.
Fallopian (uterine) tubes – these tubes
extend from the womb, one on each side. They both open near an ovary. These
tubes carry the egg (ovum) from the ovary to the
womb.
Ovaries – two small almond shaped glands
that contain ova. Sex hormones are also made by the
ovaries.
The menstrual cycle
The average cycle is around 28 days.
After a period, rising levels of the hormone oestrogen help to thicken the
lining of the womb (the endometrium).
At mid-cycle, an egg is released from one of the ovaries (ovulation). If the egg is
fertilised on its journey down the fallopian tube, it lodges in the womb lining.
If the egg is unfertilised, falling levels of the hormone progesterone make the
womb lining come away. This is called a period, or menstruation. The cycle then
repeats.

Male and Female Sexual Reproductive SystemsEach sex has their
own unique reproduction system. They are different in shape andstructure, but
both are specifically designed to produce, nourish, and transport either the egg

The male reproductive system
The male reproductive system is made up of
the penis, the testicles, the epididymis, the vas deferens and the prostate
gland. theri sex cell is called sperm.
Penis – has special erectile tissue that can fill with blood and make the
penis stiffen. Sperm leaves the penis through the urethra, the same tube used
for urination.
The testicles (testes) – small oval sex
glands located in a skin sack called the scrotum. Sperm and sex hormones are
made by the testicles. Keeping the testicles outside of the body means they have
a lower temperature, which is important for sperm
production.
Epididymis – a series of small tubes
attached to the back of each testicle. The epididymis collects and stores
sperm.
Prostate gland – along with the seminal
vesicles, adds fluid to the sperm.
Sperm
The sperm is the male reproductive cell.
Its role is to fertilise an egg and it contains genetic material. A sperm
is tadpole shaped and around 60 microns in length (one micron is a millionth of
a metre). It has a lashing tail, which helps it to ‘swim’ towards a waiting
egg.

The importance of studying the reproductive system is because all organ systems in the body work together. So basically, it is to examine the functions of this system and others systems. As you may know, the cardiovascular system works with the respiratory system, muscular system, excretory system, and more. Also, it can be used to learn about genetics.
