Contemporary Issues on Contraception Worldwide contraceptive usage increase Planning for wanted children Physical health of mother Insurance coverage of contraceptives Population growth Cultural gender-role expectations Wide diversity of views among cultures and religious groups
Sharing Responsibility for Contraception Ask about birth control before intercourse Read and discuss options together Attend a class or clinic together Share expenses
Choosing a Birth Control Method Consider effectiveness and cost Consider ease of use and side effects Characteristics of ineffective use
Hormone-Based Contraceptives 4 Basic Types of The Pills Combination pill Triphasic pill Constant dose Progestin-only pill
Other Hormone-Based Contraceptives Vaginal ring Transdermal patch Injected contraceptives
Barrier Methods Male Condom Female Condom Sheath fits over erect penis Female Condom Worn internally by a female Additional protection from condoms
Vaginal Spermicides Can be purchased in pharmacies without a prescription Types Foam, sponge, suppositories, creams, contraceptive film (VCF)
Cervical Barrier Devices Diaphragm Cervical cap FemCap Lea’s Shield
Intrauterine Devices Affect sperm motility and viability Thicken cervical mucous Alter endometrial lining Impair tubal motility
Emergency Contraception Hormone Pills Birth control pills taken within 72 hours of unprotected intercourse Copper-T IUD Inserted up to 5 days after unprotected sex Access issues and advancement
Fertility Awareness Methods Standard days method Mucus method Calendar method Basal body temperature method
Sterilization Most effective method Leading method in U.S. and the world Reversal about 50% effective
Nursing A Less than Effective Method of Birth Control Amenorrhea is common for a brief period after birth while breastfeeding 80% ovulate before first period
Withdrawal Before Ejaculation A Less than Effective Method Difficult to judge when to withdraw Anxiety may lower pleasure Cowper’s gland fluid may carry sperm Any sperm on vulva may travel into vagina/uterus Unreliable
New Directions in Contraception Males Progestin/Testosterone implant or injection Medication to prevent ejaculation during orgasm Reversible vasectomy in clinical trials Females Non-hormonal methods Contraceptive vaccine, vaginal ring, spermicide Spray on contraceptive Spermicide to protect against STIs

Infertility Diagnosis Causes Challenges in relationships More than 6 months of trying = problem Not conceiving after at least 1 year 1 in 6 U.S. couples seek help Causes Complex, hard to determine Unidentifiable in 15% of cases 85-90% of cases can be treated Challenges in relationships
Female Infertility Failure to ovulate regularly Below normal body weight Smoking and substance abuse Infertility increases with age Cervical mucus may destroy sperm Sperm may not reach the egg Fertilized egg may not implant
Male Infertility Abnormal sperm count or motility Caused by poor nutrition Substance abuse Environmental toxins STIs Impaired sperm production Varicocele Congenital abnormalities
Reproductive Technologies Artificial insemination Surrogacy Assisted reproductive technology (ART) In vitro fertilization (IVF, ZIFT, or GIFT) Do you think children conceived by donor sperm and/or egg insemination should be told about this? Why or why not?
Concerns Regarding Reproductive Technologies Expense Legal, ethical, and personal dilemmas 75% failure rate 20-30% end in multiple embryos Health concerns
Pregnancy Detection First signs Nausea/Vomiting: appetite change Light period, spotting, or no period; fatigue; tender breasts Nausea/Vomiting: appetite change Blood or urine for HCG Subtle softening of uterus at 6 weeks
Miscarriage Spontaneous Abortion Occurs in first 20 weeks 10-20% of all pregnancies Emotional impact can be significant Individual or couple may consider grief support
Elective Abortion U.S. Statistics Part 1 25% of U.S. pregnancies end in elective abortion 1% occur after 20 weeks 50% of women will have abortion by age 45

U.S. Abortion Controversy Historical Overview Early American law allowed abortion until quickening (movement of the fetus) 1973: Roe vs. Wade 1977: Hyde Amendment State restrictions or limitations Waiting period, parental notification
U.S. Abortion Controversy Current Debate Majority of Americans believe abortion should remain legal Pro-life goals Pro-choice goals
Experience of Pregnancy Wide range of positive and negative emotions Emotions are affected by physical changes First trimester increased fatigue, nausea, and breast changes Second trimester movement felt; heightened sense of well-being Third trimester increased size; greater discomfort
Pregnancy at Ninth Month Caption: Pregnancy in the ninth month. The uterus and abdomen have increased in size to accommodate the fetus.
Experience of Pregnancy Male Partner Ecstasy to ambivalence to fearfulness Male partner may feel closeness or separation toward female counterpart Concern about financial impact Active involvement helps
Fetal Development First Trimester Zygote: united sperm cell and ovum Blastocyst: multiple cells that implant Heartbeat at 9-10 weeks after last period 2nd month: spinal canal, arms/legs 3rd month: internal organs
Blastocyst Caption: The blastocyst implanted on the uterine wall shown (a) in diagram and (b) in photo taken by a scanning electron microscope.
Fetal Development Second Trimester Sex of fetus can be distinguished External body parts develop including fingernails, eyebrows, and eyelashes Skin covered by fine down-like hair Growth in size Fetal movements (quickening) by end of 4th month By end of 2nd trimester fetus has opened its eyes
Fetal Development Third Trimester Develop size and strength Down-like hair disappears Skin smoother Vernix caseosa protective creamy, waxy substance
Risks to Fetal Development Harmful substances pass to baby via placenta Prescription and non-prescription drugs 1997: viable fetus can be protected under child abuse laws Nicotine, caffeine, alcohol (FAS)
Placenta Caption: The placenta exchanges nutrients, oxygen, and waste products between the maternal and fetal circulatory systems. (a) The placenta attached to the uterine wall. (b) Close-up detail of the placenta.
Prenatal Care Health assessment before pregnancy Good nutrition Adequate rest Routine health care Moderate exercise Prenatal education
Pregnancy after Age 35 Essentially safe with prenatal care Fertility decreases with age Heightened rate of fetal defects due to chromosomal abnormalities
Contemporary Childbirth Prepared childbirth Lamaze Birthplace alternatives Homebirth
First Stage Childbirth 10 to 16 hours in duration Bloody show Water breaks Effacing or thinning of cervix Slight dilation
First Stage Childbirth Caption: (a) first stage labor.
Second Stage Childbirth 30 minutes to 2 hours in duration Begins at full dilation Infant descends through vagina Ends with delivery of baby
Second Stage Childbirth Caption: (b) Second stage labor.
Third Stage Childbirth 20 to 30 minutes in duration Begins at delivery of the baby Placenta separates and is pushed out Ends with delivery of placenta
Third Stage Childbirth Caption: (c) Third stage labor.
Cesarean Section Baby delivered through incision 1970: 5.5% U.S. births by C-section 2006: 31% U.S. births by C-section Higher C-section rates have not improved maternal and infant survival rates
Postpartum Range of feelings from excited and happy to tearful Baby blues affect 75% Postpartum depression (PPD) affect 15% Sleep deprivation heightens stress
Breastfeeding Initial colostrum has protein and antibodies Mature milk “comes in” soon Milk will “dry up” if baby does not suckle at the breast
Advantages to Breastfeeding Digestible food with antibodies Prevents uterine hemorrhage Emotional and sensual experience Promotes bonding
Short-term Disadvantages to Breastfeeding Vaginal dryness due to decreased estrogen Temporary breast tenderness Leaking milk Harder to share feeding duties
Sexual Intercourse After Childbirth Vaginal Birth After lochia flow stops and vaginal area heals 3 to 4 weeks C-section When incision healed When desire returns Varies considerably Often 6 to 8 weeks
Sexual Interaction After Childbirth Activities can include more non-coital and/or affectionate behaviors Factors that interfere Fatigue lowers desire and ability Decreased time due to caring for baby Negative pre-pregnancy attitudes
