Introduction - CONTRACEPTION • PURPOSE: prevent conception and implantation • Commonly referred to as Birth Control • Some forms may lower the risk of contracting certain STDs
“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
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
METHODS OF CONTRACEPTION(GENERAL) • Chemical: Suppressing fertility • Barrier: Preventing sperm/egg from reaching each other • Natural Methods: fertility awareness
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
The Pill: Positives • When taken properly, it is 99% effective. • Can help artificially regulate the menstrual cycle. • Can help treat ovarian cysts
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
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
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
Barrier: Male Condom • Placed over the penis immediately before intercourse • Most effective when used in combination with another method
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
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
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
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

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
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!
