Parenting

Unit 2

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

Anatomy

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”

Fallopian Tube

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

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.

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

Reproduction

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

puberty.

headaches

night sweats

early wakening

frequent urination

mood changes
