  1. Sex Ed • La Canada High School • Dr.E • Based in part on Kevin Patton. LionDen.com

  2. Why Sex Ed?

  3. Youth Talk about Sex Education • We can’t talk to parents • Schools limit or prohibit discussion • They only seem to want to restrain it • Abstinence only Sex Education • The adults should be helping youth learn to deal with the consequences of sex

  4. Sexual Initiation • The younger the age of first sexual intercourse • more likely forced sexual intercourse • greater the risk of unwanted pregnancy • greater the risk of sexually transmitted infections 6

  6. Sexual Abuse • Estimates of sexual abuse by age 18 • Unwanted kissing or touching. • Unwanted rough or violent sexual activity. • Rape or attempted rape. • Refusing to use condoms or restricting someone’s access to birth control. • Keeping someone from protecting themselves from sexually transmitted infections (STIs). • Sexual contact with someone who is very drunk, drugged, unconscious or otherwise unable to give a clear and informed “yes” or “no.” • Threatening someone into unwanted sexual activity. • Repeatedly pressuring someone to have sex or perform sexual acts.  • Repeatedly using sexual insults toward someone. 

  7. Sexual Abuse • Estimates of sexual abuse by age 18 • Females • 1 in 3 (33%) • Males • 1 in 6 (17%)

  8. Teen STI • 18.9 million new cases of STIs yearly • 9.1 million (48%) among 15–24-year-olds • 25% of teenage females are STI positive • 25% of the sexually active population • HPV infections account for about half of STIs diagnosed among 15–24-year-olds each year

  9. Chances of STI • Let’s Review • 50% of Teens have had sex

  10. Chances of STI • Let’s Review • 50% of Teens have had sex • If you have not had sex of any kind you can not get an STI

  11. Chances of STI • Let’s Review • 50% of Teens have had sex • If you have not had sex of any kind you can not get an STI • 25% of female teens have an STI (and therefore about 25% of all male teens)

  12. Chances of STI • That means you have a 50% of having sex with someone that has an STI

  13. Warning: This part of the course includes graphic sexual content

  14. Sexual Mode of Reproduction • Sexual/Two parent allows more variation • Individual genes • Want to survive • Form coalitions with different genes to improve chances • Improve chances some copies will survive • End up in combinations that will be successful

  15. Basics: Gonads • Primary sex organs • Produce gametes and sex hormones • Male gonad: Testis (testes) • Female gonad: Ovary • Only one gonad is needed • Most have spare in case or injury or disease

  16. Basics: Gametes • Reproductive Cells • Half the number of nuclear DNA molecules (chromosomes) • Gametes are haplid (23 chromosomes) • Body Cells are diploid (46 chromosomes) • Male Gamete: Sperm(atozoa) • Female Gamete: Ovum (ova) or oocyte

  17. Basics: Similarity of Tracts • Both Male and Female have • paired gonads

  18. Basics: Similarity of Tracts • Both Male and Female have • paired gonads • paired tubes to carry gametes from gonads to exterior of body

  19. Basics: Similarity of Tracts • Both Male and Female have • paired gonads • paired tubes to carry gametes from gonads to exterior of body • Y-shaped structure

  20. Basics: Similarity of Tracts • Derived from same tissue and are analogous structures • Folds of outer rim of female outer genitals (labia) • Male version is scrotum - fused in midline to house testes that drop from abdominal region

  21. Male Functional Anatomy • Testes • Reproductive Tract • Accessory Glands • Penis • Spermatogenesis • Seminal Fluid (semen) • Capacitation • Endocrine Regulation

  22. Testes • Male gonads that come in pairs • Spermatogenesis

  23. Testicular Structure • Scrotum • Fold of skin into which testes descend • Stretch into a pouch • Muscles regulate position of testes relative to body • Temperature Regulation

  24. Testicular Structure • Lobules • 250 per testis • Contain Seminiferous tubules • (70 cm each) • site of spermatogenesis

  25. Testicular Structure • Lobules • 250 per testis • Contain Seminiferous tubules • made of germinal epithelium (70 cm each) • site of spermatogenesis • Interstitial cells of Leydig • between tubules - secrete androgens

  26. Male Functional Anatomy • Testes • Reproductive Tract • Accessory Glands • Penis • Spermatogenesis • Seminal Fluid (semen) • Capacitation • Endocrine Regulation

  27. Epididymis • SIX meters of coiled tubule alongside testes

  28. Epididymis • SIX meters of coiled tubule alongside testes • Storage and conduction of semen • Sperm and Spermatc fluid • Sperm learn to swim • Secretes <5% seminal fluid • Contains glycogen (to nourish sperm)

  29. Ductus - Vas Deferens • Muscular tube • Last part widens to form ampulla

  30. Ductus - Vas Deferens • Muscular tube • Last part widens to form ampulla • Conducts semen from epididymis toward bladder to join urethra (during emission) • L & R duct extend through prostrate and to the urethra

  31. Urethra • Shared by reproductive and urinary systems • Extends through penis • Prostatic Urethra
