Girls
• Hormones target the two ovaries, which
contain eggs that have been in the girl's body
since she was born.
• The hormones cause the ovaries to start making
another hormone, called estrogen.
• Together, these hormones prepare a girl's body
to start her periods and be able to become
pregnant someday.
Taking Shape
• Girls' bodies become curvier.
• Hips get wider and their breast develop
• Girls may start wearing bras around this
time, especially if they are involved in
sports or exercise classes.
Questions Girls are Thinking!
• When will I get my first period?
– This usually happens about 2 years after her
breasts start to develop. The menstrual cycle is
when blood is released through the vagina.
• When can I wear a bra?
The Female Reproductive Anatomy
• Ovary
produces ovum or eggs
and the female hormones
estrogen and
progesterone
• Ovum
the female reproductive
cell or eggs, which
contribute the X
chromosomes
OvaryEgg
Fallopian tubes
The Female Reproductive Anatomy
• Fallopian tubes
tubes transporting the ovum or egg
to the uterus
fertilization occurs here
• Uterus
when an egg is fertilized, it implants
in the lining of the uterus
when there is not a fertilized egg,
the lining of the uterus sheds
known as the “womb”
The Female Reproductive Anatomy
• Cervix
bottom end of the uterus
opening between the
uterus and vagina,
where sperm, menstrual
fluid and the fetus pass
through
• Vagina
pathway for menstrual
flow and sperm, as well
as the birth canal
Cervix
Vagina
Menstruation
• The female’s body releases an ova or egg from the
ovaries
ovaries begin to produce more estrogen and other hormones
• Happens usually every month and lasts between three
and seven days
• A girl’s first period is called menarche

Ovulation is when the ovaries release a ready egg or ovum.

Blood
Menstruation Process1. Ovary releases
one egg about
once a month
2. Released egg travels down
the Fallopian tubes to the
uterus
3. Uterus’
lining
begins to
fill with
blood and
fluid when
this
happens
When you were born, you had about 60,000 eggs.
On average, you ovulate half the time from one ovary and the other time from the other ovary.
Fertilization is when the sperm from a male
joins an egg from a female.
Fertilization
• While the egg is in the uterus, it can join with sperm from
a male
• If this happens, then a pregnancy occurs, and the baby can
grow in the uterus
• If this does not happen, then the egg dissolves and the
blood and fluid from the uterus is released through the
vagina
Female Reproductive Problems
• Female reproductive disorders can
include:
ovarian cyst
ovarian cancer
endometriosis
Female Reproductive ProblemsOvarian cyst
An ovarian cyst is a sac filled with fluid that forms on or
inside of an ovary
mainly occurs during childbearing years
Tend to disappear within 8-12 weeks
Ovarian cancer
has several risk factors
− if family members have the disease
− unexplained infertility
− no pregnancies
Female Reproductive Problems
EndometriosisA condition in which the tissue that behaves like the cells
lining the uterus (endometrium) grows in other areas of
the body, causing:
pain
irregular bleeding, and
possible infertility
The tissue growth (implant) typically occurs in the pelvic
area, outside of the uterus, on the ovaries, bowel, rectum,
bladder, and the delicate lining of the pelvis. However, the
implants can occur in other areas of the body, too.
Menopause
Is when a woman has her last menstruation the average age menopause occurs is 51
• Has symptoms, such as:
achy joints
hot flashes
changes in sexual desire
extreme sweating
Menopause is another
major change in a
woman’s life, much like
