Menstruation

• About once a month, a tiny egg leaves one of the
  ovaries (ovulation)
• In the days before ovulation, the hormone
  estrogen stimulates the uterus to build up its
  lining with extra blood and tissue, making the
  walls of the uterus thick and cushioned.
• This happens to prepare the uterus for pregnancy
  If the egg is fertilized by a sperm cell, it
  travels to the uterus and attaches to the
  cushiony wall of the uterus, where it slowly
  develops into a baby.

12
Menstruation

• If the egg isn't fertilized, it doesn't attach to
  the wall of the uterus.
• When this happens, the uterus sheds the extra
  tissue lining. The blood, tissue, and
  unfertilized egg leave the uterus, going through
  the vagina on the way out of the body.

13
Menstruation

• Just as some girls begin puberty earlier or later
  than others, the same applies to periods. Some
  girls may start menstruating as early as age 10,
  but others may not get their first period until
  they are 15 years old.
• The amount of time that a girl has her period
  also can vary. Some girls have periods that last
  just 2 or 3 days. Other girls may have periods
  that last 7 days or longer.

14
How Long Does Puberty Last?

• Puberty generally lasts from age 9 to 16 for
  girls.
• Average girl will grow 12 inches and gain 40
  pounds during this time.
• Puberty generally lasts from age 12 to 18 for
  boys.
• Average boy will grow 16 inches and gain 20
  pounds during this time.

15
Personal Hygiene

• Oily Hair
• Each strand of hair has its own sebaceous (oil)
  gland, which keeps the hair shiny and waterproof.
  But during puberty, when the sebaceous glands
  produce extra oil, it can make your hair look too
  shiny, oily, and greasy.
• Washing your hair every day or every other day
  can help control oily hair.
• You might want to try one that is specially
  formulated for oily hair.

16
Personal Hygiene

• Body Odor and Sweat
• During puberty your sweat glands work harder than
  ever before.
• The best way to keep clean is to bathe or shower
  every day using a mild soap and warm water. This
  will help wash away any bacteria that contribute
  to the smells.
• If you're concerned about the way your underarms
  smell, you can try using a deodorant or deodorant
  with antiperspirant.
