Chapter Eleven Contraception and Birth Control
Risk and Responsibility • In the United States, half of all pregnancies are unintended • Half of unintended pregnancies occur in couples who do not use contraception • Those who discuss preventing pregnancy are most likely to use contraceptives
Men, Women, and Birth Control: Who Is Responsible? • Women may have a greater interest than male partners in controlling fertility • Traditionally been seen as the woman’s job • Male-controlled methods now account for 35% of reversible contraceptive use
Adolescents and Contraception • Adolescents are less likely than older individuals to use contraction • Condoms are preferred method • Condom use may be stigmatized
Birth Control and Contraception: What’s the Difference? • Birth control: any means of preventing a birth from taking place; includes contraception and abortion • Contraception: birth control that works specifically to prevent conception
Choosing a Method • Best method is the one you will use correctly and consistently • Theoretical effectiveness assumes consistent and correct usage • User effectiveness: Actual statistical effectiveness incorporating those who use method but do not do so consistently and correctly
Sexual Abstinence • Most reliable form of birth control • Involves refraining from sexual activity that could cause pregnancy • Abstinence doesn’t necessarily rule out affection or non-coital sexual activities • Practitioners’ definitions of abstinence vary • From a contraceptive perspective, abstinence from vaginal intercourse is required
Hormonal Methods Oral contraceptives • “the pill”; the most widely used form of reversible contraceptive in the U.S. • Highly effective in preventing pregnancy • Contains progestin and (usually) estrogen • How they work: • Suppress ovulation • Thicken cervical mucous • Thin the lining of the uterus • Slow the rate of ovum transport
Hormonal MethodsOral contraceptives • Effectiveness rates • Suppresses ovulation • Multiple types • Advantages • Disadvantages • Possible problems
Other Hormonal Methods • Injectable contraceptives: Depo - Provera • The Patch: Ortho Evra • Effectiveness rates • Advantages • Disadvantages • The vaginal ring: Nuva Ring
Other Hormonal Methods • The vaginal ring: Nuva Ring • Effectiveness rates • Advantages • Disadvantages • Implants: Jadelle
Barrier Methods of Contraception • Condom • Spermicide: nonoxynol – 9 • Latex vs. polyurethane • Women and condom use • Effectiveness and advantages • Possible problems • The female condom
Barrier Methods of Contraception • Diaphragm and Cervical Cap • Both cover the cervical opening to prevent entry of semen • Both are filled with spermicidal jelly and cream • Different shapes and style of fit • Effectiveness • Advantages • Possible problems
Barrier Methods of Contraception • Contraceptive sponge • The FemCap • Spermicide • Foam • Film • Creams, jellies, and vaginal suppositories
Intrauterine Device (IUD) • Tiny plastic or copper device inserted into uterus • Multiple types currently available • 10-12 years • Not an abortifacient • Projections for increased popularity
Fertility Awareness Based Methods • Calendar (rhythm) method • Basal body temperature (BBT) method • Ovulation method • Symptothermal method
Men: Vasectomy Women: Tubal ligation Laparoscopy Essure Sterilization
Emergency Contraception • Taken within 120 hours of unprotected sex • Plan B • Concentrated doses of progestin and/or estrogen • Stops ovulation, fertilization, and implantation • Will not abort an established pregnancy • Different from “abortion pill” • Copper IUD • Less common method; interferes with implantation
Abortion • Medical definition: expulsion of the conceptus • Can happen naturally (miscarriages) • Can be medically or surgically induced • Abortions are not all the same • Circumstances of pregnancy vary • Differences by stage of pregnancy
Abortion • Under safe, clean, legal conditions abortion is a safe medical procedure • Self-administered or illegal abortions can be very dangerous, sometimes fatal
Methods of Abortion • Medical Abortion • A two-drug regimen (mifepristone with misoprostol) that can terminate early pregnancy. • Most effective up to 49 days after the beginning of the pregnant woman’s last period
Methods of Abortion Surgical Abortion • Vacuum Aspiration • Used in first trimester • Dilation and Evacuation (D&E) • Used in second trimester • Only 1.5% of US abortions • Hysterotomy • Used in later stages of pregnancy • Like a cesarean section; extremely rare
Prevalence of Abortion • About half of unintended pregnancies end in abortion • Highest rates: Ages 18-29, unmarried, Black or Hispanic, and/or economically disadvantaged women • Number of abortions decreased between 1994 and 2000 • Emergency contraception accounts for as much as 43% of decrease
Three Factors Leading to Abortion • Failure to practice contraception • Incorrect or inconsistent use of contraception • Failure of contraceptive method • Emotional issues for women • Reevaluation of relationships • Examination of childbearing plans • A search to understand role of sexuality • An attempt to clarify life goals
Women, Men, and Abortion • Emotional issues for men • Experience of guilt and anxiety • Ambivalence about parenthood • Powerlessness • May experience erectile or ejaculatory difficulties • Effect on relationships • Stress, conflict, and guilt sometimes lead to break-up • Clinics now provide counseling for both men and women
The Abortion Debate • Pro-life Argument • Human life begins at fertilization • Same rights in utero as after birth • Abortion is moral equivalent of murder • Pro-choice Argument • Women should be able to choose whether or not they will have children • Abortion should be available as a back-up birth control method • Women will get illegal and unsafe abortions if the procedure is made illegal
The Abortion Debate • Abortion and Religion • The Bible is silent on abortion • Scriptural basis for or against is a matter of interpretation • The debate about when human life begins is theological • American religious organizations take both pro-choice and pro-life stances
The Abortion Debate • Constitutional Issues • U.S. Supreme Court • Roe v. Wade (1973) • Webster v. Reproductive Rights (1989) • Planned Parenthood v. Casey (1992)
