10. Menstrual Cycle
One sign that a girl has reached puberty is that she begins to menstruate, or have periods.
Called a cycle because it happens over and over again.
One way a girl’s body becomes physically ready to reproduce.

11. Menstrual Cycle (cont.)
Eggs ripens in ovaries
Uterus begins building up lining (blood/tissue)
Egg released (ovulation) – 13 to 15 days before next period
Egg travels down fallopian tube into uterus (3-4 days)
If fertilized, egg attaches to uterus lining. If not fertilized, uterus will begin to shed lining in another 10 days or so (period)

12. Pregnancy Puberty anywhere from 8-14
People can then physically reproduce
Unintended pregnancies can create physical, social, emotional, and financial hardships for teens and their families
Man ejaculates sperm
Through woman’s reproductive system, and some reach fallopian tubes (can live here for up to 5 days)

13. Pregnancy (cont.)
If a woman ovulates, sperm can enter the egg (fertilization)
The egg then begins to divide and form new cells even on its way to the uterus
Pregnant when the egg attaches to the lining of the uterus
First 8 weeks – embryo
Then it becomes a fetus – 9 months

14. How is the menstrual cycle related to becoming pregnant?

15. Summary
When a woman ovulates, a ripe egg is released from an ovary into the fallopian tube.
If a woman has sex with a man and one of his sperm enters the ripe egg, the egg is fertilized and ready to implant in the lining of the uterus.
The woman becomes pregnant once the fertilized egg has attached itself to the lining of her uterus and begins to grow and develop.

16. Can a woman predict when she can get pregnant?

17. Summary Menstrual cycles are not always the same number of days.
This is particularly true for teen girls because their bodies are still maturing and some girls’ periods can be irregular at first.
It’s not a healthy or a wise choice for teens to become pregnant or get someone pregnant.
