1. -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.

2. The menstrual cycle is the regular

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). Menstruation 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.
