-fertilization of an egg by a sperm,

-normally occurs in the fallopian tubes

- fertilized egg cell is called a zygote

- the zygote then moves to the uterus, where it

implants into the lining of the uterine wall

Puberty involves the onset of sexual

maturity and the ability to reproduce. When a

female reaches puberty, egg cells start to

develop in her ovaries that produce the sex

cells. It is also the time when the body develops

the capacity to conceive.

The female reproductive system has the following

functions:

1. Produces female sex cells

2. Receives sperm cells from the male

3. Nurtures the development of and provides

nourishment for the new individual

The female reproductive system consists of the ovaries, oviducts (Fallopian tubes), uterus, vagina, and external genitalia. The internal reproductive organs

of the female are located within the pelvis, between the urinary bladder and rectum. The uterus and the vagina are in the middle part, with an ovary on each side of

the uterus.

The system involved in sexual

reproduction is called the reproductive

system. There is a striking difference between

the male and the female reproductive systems,

although they also share a number of

similarities. For example, the reproductive

organs of the male and female are developed

from the same embryological structures, and

some hormones are commonly found in both

male and female, in varying quantities and

produce different responses.

The menstrual cycle is the regular

n a t u r a l c h a n g e s t h a t o c c u r s i n

t h e u t e r u s a n d o v a r i e s t h a t make pregnancy possible.The cycle is required for

the production of ovocytes, and for the

preparation of the uterus for pregnancy.Up to

80% of women report having some symptoms during the one to two weeks prior

tomenstruation.Common symptoms include acne,

tender breasts, bloating, feeling tired, irritability,

and mood changes. These symptoms interfere with normal life and therefore qualify

as premenstrual syndrome in 20 to 30% of

women. In 3 to 8%, they are severe.

The first period usually begins between twelve and fifteen years of age, a point in time

known as menarche.They may occasionally start

as early as eight, and this onset may still be

normal. The average age of the first period is generally later in the developing world and earlier

in developed world. The typical length of time

between the first day of one period and the first

day of the next is 21 to 45 days in young women and 21 to 31 days in adults (an average of 28

days). Menstruat ion stops occurring

after menopause which usually occurs between 45 and 55 years of age. Bleeding usually lasts around

2 to 7 days.

The male reproductive system also has

prostate glands. Chemicals from these glands

nourish the sperm cells and help them mature.

The production of sperm cells and the release

of semen can be regulated by hormones or

special chemicals that come from the testis,

the brain and the pituitary gland. These

hormones keep the reproductive system

properly functioning.

The female reproductive system, just like the

male reproductive system, is also regulated by

hormones. The follicles produce hormones

that control the growth and release of eggs

from the ovaries. While other hormones

prepare the uterus so a baby can grow in it,

other hormones still control the stretching of

the uterus during pregnancy.

Hormones play an important role in

both male and female reproductive systems.

The pituitary gland controls the functions of

both the testes and the ovaries. These

hormones keep the reproductive system

properly functioning.
