ANATOMY Date: Agenda I. II. III. IV. V. Arrival and Sign in Anatomy review – label diagrams True or False? Activity “Language of sex” activity Wrap-up Knowledge and skills Identify major organs of the male and female reproductive system and their functions Understand and explain the processes of intercourse and fertilization Correct misconceptions about anatomy and reproductive system Begin to become comfortable talking about anatomy and sex Learn the correct terminology to use when talking about anatomy and sex II. Anatomy review a. Activity: Students will receive diagrams of the male and female outer reproductive systems (genitals). The labels for each organ will be left blank, and a word bank provided. We will fill in the sheet together, and review the functions of each organ. b. Female diagram: - Ovaries – glands that produce eggs, hormones - Fallopian tubes – narrow tubes that extend from the ovaries to the uterus, tunnels for egg cells, where fertilization occurs - Uterus – home for fetus - Cervix – the lower part of the uterus that opens into the vagina - Vulva – female outer genitals (vagina, labia) - Labia – inner and outer - Vagina – canal that joins cervix to outside of body, menstruation, sperm entry, birth canal - Clitoris – sensitive spot upper vulva, pleasure, internal and external almost the size of penis - G-spot – (Grafenburg spot) spongy tissue, another source of pleasure - Urethra – urination c. Menstrual cycle review - Born with 1-2 million eggs - Menstruation (days 1-8), blood and tissue from the uterus inner lining flows out of the vagina (period) - Hormones cause egg to mature in one of ovaries (days 9-13) - In the days before ovulation, the 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 - Ovulation occurs (egg released from ovary), egg travels to one of fallopian tubes (day 14), if not fertilized by sperm during this time then egg starts to dissolve - Eggs travels to uterus, if not fertilized then cycle starts again (days 15-28) - 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 d. Male diagram: i. Penis – ejaculate and urinate ii. Testicles – below the penis, produce sperm and testosterone iii. Scrotum – pouch of skin that covers the testicles, regulates temperature (important for sperm production) iv. Epididymis – stores sperm after produced by testicles v. Vas deferens – transports sperm to urethra vi. Urethra – duct that transports fluids outside the body, bladder and semen vii. Prostate gland – add fluid to semen e. Male anatomy cont. i. Sperm: made in the testicles, needs a specific temperature, stored in the epididymis. Mixes with other fluids before ejaculation to make semen. There are 200-600 million sperm in one ejaculation ii. Semen that remains in the female body carry sperm that can survive for 3-5 days iii. Pre-cum: A fluid which the penis usually emits with or around erection and before ejaculation, sometimes more than once. Pre-ejaculate itself does not contain sperm, but in some cases, can pick up traces of sperm left in the urethra. III. True or False? 1. A girl can’t get pregnant if… ii. She has sex standing up iii. She douches after sex iv. She has sex while on her period a. All FALSE: risk of pregnancy from vaginal sex in any position; washing out the vagina does not prevent sperm from reaching the egg; sperm can reach the egg at any time, and can live in the female for up to a week 2. The size of a man’s nose, hands, ears, or feet tells you how large his penis is. a. FALSE: the size of a man’s penis is determined only by genetics and is not related to the size of other body parts, or general body shape 3. A woman is temporarily infertile while she is nursing a baby. a. FALSE: some women may not ovulate during breastfeeding time, and therefore will not become pregnant until after they stop nursing, but not all women 4. Cancer of the testicle is more common among teenage males than among men over 35 a. FACT: Cancer of the testicle is rare, but usually occurs among teen and young men. The first sign is a lump on the testicle. 5. All penises are the same size when erect a. FACT: size when it is flaccid has no bearing on size when erect, in most men the size is equalized during erection 6. Anal intercourse is a safe way for women to avoid pregnancy and STDs a. FALSE: anal intercourse is one of the easiest ways to spread HIV and other STDs. The anus is not as elastic as the vagina, is not lubricated, and can tear more easily, allowing viruses and bacteria to enter directly into blood. A woman can become pregnant from anal sex if semen seeps out onto the vulva, into vagina (look at your diagrams, the anus is close to vagina!) 7. Women will always bleed and feel pain when they have intercourse for the first time a. FALSE: The hymen is a thin membrane that partially covers the vaginal entrance, they vary in size and thickness and some women don’t have one. If a woman’s hymen has never been stretched or torn, there may be bleeding, but the hymen can also be stretched by normal physical activity. Bleeding and pain may also occur if woman is tense or not properly lubricated. 8. A woman with heavy discharge from her vagina probably has an STD a. FALSE: all women have normal vaginal discharge, it is vagina’s natural way of cleansing itself. Amount of discharge varies by woman, time in menstrual cycle. If discharge itches or burns or has a different color that may be a sign of STD. 9. When a man gets aroused and has an erection, he must ejaculate to avoid harmful effects a. FALSE: semen does not get backed up and cause infection, may feel heaviness if excited for a long period of time, but goes away once stimulation stops. b. Discuss results, who got them correct? Explain the validity of statements. OR Reproductive Anatomy Jeopardy – see Knox County Lesson Plans in Activities folder IV. “Language of sex” activity a. Write words on a board or big piece of paper, ask students to call out synonyms (can be slang) for these terms. If the group is large enough, split into two and have teams brainstorm to get the longest list. b. Terms: penis, vagina, masturbation, breasts, testicles, sex/intercourse (oral, anal, and vaginal) c. Follow-up questions: - How did you feel while doing this exercise? Did your feelings change? - Which words were difficult to say or hear? - What language are you most comfortable with? - How do we usually talk about sex? d. Knowledge/skills: learn the correct terms to use when talking about sex and anatomy. Discuss the different languages used when talking about these topics – scientific, childhood, slang, common language. Goals: to make students comfortable, talking about terms that may be uncomfortable out loud; to lay out terminology we will use in our group Female/Male Anatomy: http://www.iwannaknow.org/teens/sexualhealth/know.html Reproduction 101: http://www.advocatesforyouth.org/index.php?option=com_content&task=view&id=232&Itemid=129 Male: http://www.scarleteen.com/article/body/anatomy_mans_best_friend_male_sexual_anatomy Female: http://www.scarleteen.com/article/body/anatomy_pink_parts_female_sexual_anatomy
