  1. Let’s talk about sex… • Catalyst: • Make a list of all the inappropriate words for male and female genitalia (private parts) that you know. • Write. DO NOT say. Write in complete sentences! Don’t talk during the Catalyst!

  2. Objective By the end of today, SWBAT… • RESPECTFULLY and MATURELY talk about sex

  3. Agenda • No catalyst review • Why study sex in school? • Introduction to the Question Box • Pre-Test: “Myths and Facts” • Exit Question

  4. Why study sex-ed in biology? • Sex is the function of the reproductive system • Why would we study a system without studying what it’s used for? • Sex is central to genetics and evolution • Biology is the study of life—including our own • Sex is an important part of the human experience • Humans are one of very few species that have sex for pleasure

  5. Question Box

  6. What do YOU know about sex? • Before we learn about sex, we need to confront some important potential misconceptions that you may have • The purpose of this is not to make you feel insecure OR super-cool.

  7. Sperm and Egg • What are the two cells called that must unite to make a baby?

  8. Please write down, using as much scientific language as you can, how babies are made. Babies are made as the result of sexual intercourse, during which a sperm (from the father) enters an egg (from the mother). This is called “fertilization.” The sperm can reach the egg only when sperm gets into a woman’s vagina. Sperm comes out of a man’s penis during ejaculation. Women always have eggs inside of them.

  9. Here are some of the common STIs: • Herpes (cold sores and genital herpes) • Gonorrhea • Syphilis • Chlamydia • HIV/AIDS • HPV • Please write down the names of any sexually transmitted infections (STIs) you have heard of.

  10. What can couples do to prevent pregnancy? Be specific! Condoms, oral contraceptives, nuva ring, spermicide, depo-provera, diaphragms

  11. You cannot get pregnant if you have sexual intercourse in water. • You cannot get pregnant if the woman is on her period. • You cannot get pregnant if the male “pulls out” before ejaculating (when the sperm comes out). FALSE—you can get pregnant any time you are not using contraceptives FALSE—a woman can still get pregnant! FALSE—there is sometimes sperm in the “pre-cum” that comes out of the penis, even before ejaculation.

  12. FALSE—HIV/AIDS is transmitted through the blood, ejaculate, vaginal fluid. • HIV/AIDS is transmitted (you can catch it) through tears and spit. • Only needle drug users and male homosexuals have HIV/AIDS. • Peeing after sex washes out sperm and prevents women from getting pregnant. FALSE—one of the fastest growing groups of people getting HIV are heterosexual women. FALSE—the vagina and urethra (where you pee from) are two different places.

  13. FALSE—there is an emergency pill you can take up to 3 days after unprotected sex called Plan B (anyone 17 or older can buy it for $50 at Walgreens). 89% effective! • If a condom breaks and the woman is not taking oral contraception (“the pill”), there’s nothing you can do to prevent pregnancy. • The only way to be sure that you won’t get an STI or become pregnant is not to have sex (abstinence). • Condoms, when used correctly, can prevent most STIs and pregnancies. TRUE—not having sex is the only way to be 100% safe. TRUE

  14. If both people don’t say yes to sex (give consent), it is sexual assault (rape). • You can’t do anything to treat or cure any sexually transmitted infections (STIs). • You can’t get pregnant your very first time having sex. TRUE—you should ALWAYS be sure that both people want to have sex (asking is the best way to be sure). FALSE—some STIs can be vaccinated, some can be cured, some can be treated (but not cured). FALSE—you are just as likely to get pregnant your first and 50th time.

  15. Every person who has a sexually transmitted infection knows they have it, even without being tested by a doctor. • Condoms are not 100% effective, so you should not use them. FALSE—many people have STIs without knowing it because they are asymptomatic. The only way to know is to get tested by a doctor. FALSE—condoms are over 98% effective when used properly, and they are one of the cheapest ways to protect yourself.

  16. About half of all pregnancies were not planned by the parents. • It is important to know about how to protect myself from pregnancy and STIs so I can protect my health and be more empowered. TRUE TRUE—knowing how to take care of your health is one of the best ways to value yourself and your life. It’s also important to be able to decide when you want to have kids.

  17. Question Box • Please pick up a slip of white paper. • Write down one question you have about sex. • You may ask anything. • It does not have to be directly related to anything we have talked about so far.

  18. Reproductive Anatomy • Key Point #1: Different organs make up the male and female reproductive systems.

  19. Male Reproductive Organs Testes Vas deferens Penis Urethra

  20. Female Reproductive Organs Ovary Fallopian tubes (oviduct) Uterus Cervix Vagina Vulva

  21. Pregnancy • Key Point #2: Men and women are fertile at different times • Fertile = able to become pregnant or cause a pregnancy • After puberty, men produce sperm every day, and can impregnate women at any time • Women go through a cycle that determines when they can get pregnant

  22. Menstrual Cycle • Key Point #3: Women have 26-32 day menstrual cycles

  23. Whiteboard Practice (GP) • Name two organs of the male reproductive system. • What does the vas deferens do? • What does the penis do? ADD IT!!! If you can’t find the answer…

  24. Whiteboard Practice (GP) • Name three organs of the female reproductive system. • What does the cervix do? • What does the ovary do? ADD IT!!! If you can’t find the answer…

  25. Whiteboard Practice (GP) • When are men fertile? • When are women fertile? ADD IT!!! If you can’t find the answer…

  27. Whiteboard Practice (GP) • How does orgasm help pregnancy to occur? ADD IT!!! If you can’t find the answer…

  28. Independent Practice – Choose One • You are a sperm. Explain to your little sperm brother the path that he must go through in order to get to an egg and fertilize it. • You are an egg. Explain to your little egg sister what will happen when she is released from the ovaries. (Make sure she knows what will happen if she is not fertilized).

  29. Key Point Wrap-Up • Key Point #1: Different organs make up the male and female reproductive systems. • Key Point #2: Men and women are fertile at different times • Key Point #3: Women have 26-32 day menstrual cycles

  30. Describe the path that a sperm cell takes, from creation to release from the body during orgasm. What happens during each of the phases of the menstrual cycle? Exit Question: Choose one Write in complete sentences! Don’t talk during the Exit Question!
