  1. Contraception

  2. Introduction - CONTRACEPTION • PURPOSE: prevent conception and implantation • Commonly referred to as Birth Control • Some forms may lower the risk of contracting certain STDs

  3. “Safe Sex” • Many teens have heard the term “safe sex” • This is the idea that using a contraceptive will protect one from the unwanted physical consequences of sex • NO CONTRACEPTIVE IS 100% EFFECTIVE IN PREVENTING PREGNANCY OR STDS

  4. Let’s Review… • Women’s Fertility – • hormones cause the release of an egg once per menstrual cycle • Cervical mucus develops at the same time to help sperm motility • Lining of the uterus (endometrium) develops so the conceived embryo can implant • Men’s Fertility – produce sperm which fertilize the egg

  5. METHODS OF CONTRACEPTION(GENERAL) • Chemical: Suppressing fertility • Barrier: Preventing sperm/egg from reaching each other • Natural Methods: fertility awareness

  6. Chemical: Birth Control Pills • Chemicals introduced into the body on a daily basis for set # of days during menstrual cycle • Works in 3 ways: • Represses ovulation • Reduces lining of uterine wall • Changes density of cervical mucus making it difficult for sperm to penetrate

  7. The Pill: Positives • When taken properly, it is 99% effective. • Can help artificially regulate the menstrual cycle. • Can help treat ovarian cysts

  8. The Pill: Negatives • DOESN’T PREVENT STD’s. • Must take at the same time every day • May cost up to $40 per month • Vaginal bleeding • Spotty darkening of skin • High rate of blood clots (can be fatal) • Loss of sex drive • Irritability • Headaches (migraine-like) • Weight gain or loss • High blood pressure • Vaginal infections • Depression • Anemia • Risk of heart attack • Connections to higher risk for cancers

  9. The Pill: Negatives • Women who use a hormonal contraceptive for at least 4 years before their first full term pregnancy have a 52% higher risk of developing breast cancer • Women who use a hormonal contraceptive for more than 5 years are 4 times more likely to develop cervical cancer

  10. Chemical: Spermacides/Foams • Chemicals inserted into the vagina prior to intercourse – Spermicide: kills sperm • POSITIVE • When used in combination with other methods, fairly effective. • NEGATIVE • Do not prevent STDs • Failure rate of 21% • Messy • Can burn vagina or penis • Can have an allergic reaction

  11. Barrier: Male Condom • Placed over the penis immediately before intercourse • Most effective when used in combination with another method

  12. Male Condom • Positive • More effective in preventing STDs than pregnancies • Relatively cheap • Few side effects • Negatives • Can break or leak • Does deteriorate over time and pressure • 12% Failure rate especially among teens • Possible allergies

  13. Barrier: Diaphragm • Flat, rubber-like disc • Must be fitted by doctor • Fits over cervix • Must be inserted before intercourse and left in after (at least six hours) • Must be used with Spermacides

  14. Diaphragm Negatives Positives Effective Rate 82-94% Can be used multiple times • DO NOT PREVENT STDs • If woman gains or loses just a few pounds, it won’t fit properly • It can be jarred out of position • Risk of TSS • It may or may not be inserted properly • Possibility of allergic reaction or burns • Possible urinary tract infections

  15. Preventing Implantation: IUD (Intrauterine Device), Barrier • Usually a small metal or plastic device • Must be inserted by the doctor • Must have already delivered a child • Irritates lining of the uterus • Prevents sperm motility • Some suppress ovulation

  16. IUD Negatives Positives 99% Effective Fairly low inconvenience • DOES NOT PREVENT STDs • Possible pain • Possible puncture of the uterus • Possible internal bleeding • Increased menstrual bleeding • Complications of pregnancy and childbirth where IUD has failed

  17. Patch/Ortho Evra • Small patch applied to the skin which releases hormones similar to the Pill • Suppresses ovulation, changes cervical mucus and lining of the uterus • Patch must be changed the same day every week

  18. Patch Negatives Positives 99% effective when used correctly Needs to be changed only once a week • Skin irritation or rashes at site of Patch • Patch cannot be moved or fall off • Irregular bleeding • Fluid retention or raised blood pressure • Risk of blood clots doubled from other hormonal methods • Nausea, Headache, Breast tenderness, Mood changes • Menstrual cramps, Abdominal pain • Risk of stroke and heart attack • Does not protect against STD’s

  19. Vaginal Ring/Nuva Ring • Small ring inserted into the vagina each month which releases hormones similar to those in the Pill • Suppresses ovulation, changes cervical mucus and lining of the uterus

  20. Vaginal Ring/Nuva Ring Negatives Positives 99% effective when used correctly Change once per month • Can fall out or move • Bleeding between periods • Breast tenderness • Vomiting, Nausea • Vaginal discharge and irritation • Decreased sex drive • Irregular periods after discontinued use • Heart attack, stroke, blood clots • High blood pressure • Liver tumors

  21. Shot/DepoProvera • Injection of hormones every three months • Similar to the Pill • Suppresses ovulation, changes cervical mucus and lining of the uterus

  22. Shot/DepoProvera Negatives Positives 97% Effective Fairly Convenient • irregular or no menstrual periods • weight gain • Headaches • breast tenderness • depression • Loss of bone density (especially in adolescents) • Decrease in fertility • $35-75 per injection plus exam fees

  23. Plan B/Morning-After Pill • Higher dose of the hormones found in other chemical contraceptives • Suppresses ovulation, changes cervical mucus and lining of the uterus • Positives – • 80% Effective • Convenient • Negatives • nausea • vomiting • abdominal pain • fatigue • dizziness • menstrual changes

  24. Natural Family Planning • A woman checks her body (temperature, cervix, and cervical mucus) to identify fertile time • A couple will abstain during fertile times (5-12 days per cycle) if trying to avoid pregnancy • Method advocated by the Catholic Faith

  25. What’s the Difference? Contraception NFP Seeks to avoid fertile intercourse Recognizes the fertility involved in sex Actions show an openness to the possibility of conception For NFP to be moral, it cannot be used with a contraceptive mentality • Seeks to sterilize fertile intercourse • Take action to remove the fruitful aspect of sex • Actions display an attitude totally opposed to possibility of conception – contraceptive mentality

  26. NFP Positives Negatives Requires abstinence at times Must use properly • Inexpensive • 95-98% effective • Communication and teamwork • Respect • Learn about your bodies • No physical side effects • Self control and sacrifice • 1-3% divorce rate!

  27. NFP vs. Contraception • History records people using contraception up to 4,000 years ago • Contraception set Christians apart from the Romans, who used contraception

  28. NFP vs. Contraception • Until 1930 ALL Christian denominations agreed contraception was immoral • In the 1930’s the Anglican Church allowed contraception in certain circumstances • Eventually they caved completely and soon all major Protestant denominations followed

  29. NFP vs. Contraception • Washington Post 1931 – contraception “would sound the death knell of marriage as a holy institution by establishing degrading practices” • Ghandi, Elizabeth Cady Stanton, Theodore Roosevelt, Sigmund Freud, Dr. Elizabeth Blackwell…

  30. NFP vs. Contraception • Humane Vitae – encyclical by Pope Paul VI 1968 which condemned contraception • Society predicted there would be fewer divorces, happier marriages, fewer unwed and unwanted pregnancies, less disease, more respect, less abortions

  31. NFP vs. Contraception • About 1960-1970 the pill was widely available

  32. Decrease in Unplanned Pregnancy? • 1960 • 6% of white children born out of wedlock • 22% of black children born out of wedlock • 1992 • 22% of white children born out of wedlock • 68% of black children born out of wedlock Births to unmarried women increased from 11 to 33 percent of all births from 1970 to 1994, then leveled off through 1999.

  33. Increased Marital Happiness? • 1960 • Divorce rate – 10% • 1980 • Divorce rate – 23% Today 41-50%

  34. Fewer STDs?

  35. Fewer Abortions? • In the year 2000 – 54% of women who had abortions were using contraception • In 11 years, those numbers have not changed • More than half of women getting abortions are using contraception
