Chapter 11 Conceiving Children: Process and Choice Parenthood as an Option • More people than ever are NOT having children – 1975 – 9% of women ages 40-44 had no children – 2010 – 19% “””””””””””””””””””””””””””””””””” • Advantages of Remaining Childless – More time for self and partner – More financial resources absent the costs of parenting – Marriage less stressful • Could be due to lack of the stress of childcare decisions • Could be due to unhappy couples staying together, “for the children” – More spontaneity in social, work and recreation – More devotion to career Parenthood as an Option • However, when asked, “The rewards of being a parent are worth it, despite the costs and work it takes.” – 98% of Fathers, 97% of Mothers agreed • Advantages of Having Children – Children give and receive love – May enhance relationship as part of sharing child raising – Success builds self-esteem, sense of accomplishment – Discovering yourself as a parent can provide greater meaning and satisfaction to one’s life Becoming Pregnant Enhancing the Possibility • Intercourse just prior to or at ovulation – Unfertilized egg survives 2 days tops – Sperm last only 5 days tops – They have to meet…………. • Predicting ovulation – Cervical mucus becomes thinner and stretchy – Calendar – Basal Body Temp methods – Ovulation predictor urine tests • Based on urinary LH • • • • Infertility 60% of couples conceive in < 3 months If > 6 months consult a physician 12% of U.S. couples experience fertility problems Female infertility ~ 40% of the cause – Infertility increases with age • Changes rapidly after age 30, 46% higher, age 40 = 95% – Failure to ovulate regularly – Cervical mucus may destroy or block sperm – Sperm may not reach the egg • Infections, scar tissue – Fertilized egg may not implant – Smoking, low body fat, environmental toxins Infertility • Male Infertility ~ 40% of the cause (~ 20% is due to both) – Abnormal sperm count • Under 15 million/ml semen – Or motility • Under 50% motile at 60 min. – Or morphology – Impaired sperm production • Elevated temperature • Infections • Smoking, alcohol, drugs – Cocaine reduces spermatogenesis – MJ reduces sperm motility • Environmental factors Reproductive Technologies Artificial insemination (AI) • Insert sperm directly into female reproductive tract • Partner or donor Surrogacy = AI or IVF of a woman not part of the couple • 1000 live births in 2007 • $30K • 10% of that in India, generates $445 million/annually Assisted reproductive technology (ART), “test tube babies” • 1st one in England in 1978, now = 48,000/yr • In vitro fertilization (IVF) = sperm and egg meet in a dish – Higher rates of multiple births – Intracytoplasmic sperm injection (ICSI) = inject one sperm into egg – $15,000 + per try Thomas and Nancy Beatie at home in May 2008 prior to the birth of their first child. Thomas is an incomplete transsexual who retained his female organs. Purchased semen on the internet, did a home AI and now has three children. Nancy Beatie is unable to conceive. After a two-year, bicoastal search of fertility clinics and egg donors, Doug Okun, 38, and Eric Ethington, 37, became parents to twins Elizabeth and Sophia thanks to a surrogate mother. Janise Wulf, who is 62 years old, holds her 4-dayold baby boy, Adam, born in February 2006. the newborn is her 12th child. She used IVF and hormone therapy to maintain the uterine lining. Reproductive Technologies • Concerns Regarding Reproductive Technologies – Legal, ethical, and personal dilemmas • Extra embryos result from the procedure, what’s to be done with them? – Adoption – Research – Discard • Frozen embryos may survive marriage, who gets custody? • Genetic manipulation may be possible in the near future – “Designer babies”? • Elderly people conceiving are more likely to die prior to child maturation. Should there be an age limit? Pregnancy Detection • First signs – Light period, spotting, or no period; fatigue; tender breasts • Nausea/Vomiting: appetite change • Blood or urine for Human Chorionic Gonadotropin (HCG) – As early as 7 days after a missed period Miscarriage - Spontaneous Abortion • • • • • Occurs in first 20 weeks May show as no more than a late, heavy period 10-20% of all pregnancies Has little impact on subsequent pregnancies If fetus dies after 20 weeks, “Stillbirth” – Higher rates for teens and those over 35 years old • Emotional impact can be significant – Many couples hold a memorial ceremony • Individual or couple may consider grief support Elective Abortion, terminate a pregnancy by medical means • U.S. Statistics – 40% of unplanned pregnancies end in elective abortion – 33% of women will have abortion by age 45 – Of yearly abortion rates • 50%+ are in their 20’s, 18%+ are by teens • 61% previously given birth • 37% Protestant; 28% Catholic • Decision not an easy one – “Unprepared for motherhood” – “Cannot afford one or another child” – Men may or may not participate but the final decision is with the woman – Mental health issues following abortion are comparable to those with an ongoing pregnancy Elective Abortions, Cross-Cultural Analysis • U.S. has one of the highest abortion rates among developed countries – 21/1,000 reproductive age women have an abortion – W. Europe = 12/1,000 • All countries with lower rates provide – Comprehensive sex education – Easy access to social services, inexpensive birth control and emergency contraception • Politics – Republicans tend to reduce public reproductive services – Democrats tend to increase them Types of Abortion Procedures • 92% of legal abortions happen <12 weeks – Risks are low = 0.1/100K deaths – Pregnancy = 11.8/100K deaths • Medical abortion – pills to end a pregnancy – “Morning after”, should be called “right after” because it’s really only good for about 72 hrs, tops. – RU486, use up to 9 weeks along – 99% effective < 7 weeks, 91% @ 8 weeks. – Side effects include headache, cramping, nausea, vomiting – Many women have no side effects Types of Abortion Procedures • Suction curettage – Used for pregnancies from 7 – 13 weeks along – Just like it sounds, under anesthesia, a suction tube is inserted into the uterus and the contents are suctioned out – Rare complications include infection, perforation, bleeding, incomplete evacuation • Dilation and evacuation (D and E) – 13 to 21 weeks, but higher risk factors – Suction, forceps + curettage • Prostaglandin induction into uterus to induce contractions • Late-term abortion (intact D and E) – 20 to 24 weeks – Used when her health is at risk or fetal abnormalities exist – AKA, “Partial Birth Abortion”, but this is not technically correct Types of Abortion Procedures • Illegal abortion – 21.6 million/yr worldwide – 47,000 women’s deaths – Millions with reproductive damage – Drink turpentine, bleach, livestock manure tea to induce contractions – Insert herbs, sticks, coat hangers, bones into uterus to induce – Such attempts have been recorded for centuries Abortion supporters (47%) and opponents (47%) usually believe very strongly in their positions. Deaths from abortion declined dramatically after legalization. Experience of Pregnancy • Mothers – Wide range of positive and negative emotions – Emotions are affected by physical changes • Fathers – 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, 0-13 weeks • Zygote: united sperm cell and ovum in fallopian tube – Rolls slowly toward the uterus while dividing • 1 week = Blastocyst: multiple cells that implant • Heartbeat at 9-10 weeks after last period • 2nd month: spinal canal, arms/legs • 3rd month: internal organs HUMAN DEVELOPMENT: ONE MONTH All early vertebrate embryos resemble these human embryos Note the tail, pharyngeal gill arches, and paddle-like limb buds HUMAN DEVELOPMENT: ONE MONTH HUMAN EMBRYO: EARLY ORGAN DEVELOPMENT EXTRAEMBRYONIC MEMBRANES Chorion Allantois Amnion HUMAN DEVELOPMENT: THREE MONTHS Note the extraembryonic membranes and other support structures Fetal development at 9 weeks. the fetus is connected to the placenta by the umbilical cord. The placenta exchanges nutrients, oxygen, and waste products between the maternal and fetal circulatory systems Fetal Development, Second Trimester, 4th month+ • 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 to about 1+ lb. • Fetal movements (quickening) by end of 4th month • By end of 2nd trimester fetus has opened its eyes HUMAN DEVELOPMENT: FIVE MONTHS Fetal Development, Third Trimester • Develop size and strength – 7-12 lbs. – Mom gains 25-35 lbs. • Down-like hair disappears • Skin smoother • Vernix caseosa – protective creamy, waxy substance Prenatal Care • • • • • • • Health assessment before pregnancy Good nutrition + folic acid Adequate rest Routine health care Moderate exercise Prenatal education Increased risk of fetal chromosomal abnormalities after 40 years old • Increased risks to mother after age 35 Contemporary Childbirth • Prepared childbirth – Lamaze – Bradley • Birthplace alternatives – Birthing centers with midwives • Homebirth • C-sections – 1 in 3 births Childbirth, AKA tax deduction arrival • First stage – 10 to 16 hours in duration 1st time, 4-8 hrs 2nd time – Effacement or thinning of cervix – “Bloody show” as the cervix dilates toward 10 cm – “Water breaks” as the amniotic sac ruptures • Second stage – 30 minutes to 2 hours in duration – Begins at full dilation – Baby enters vaginal canal – Ends with delivery of baby • Third stage – 20 to 30 minutes in duration – Begins at delivery of the baby – Ends with delivery of placenta THE BABY EMERGES IN THE SECOND STAGE OF BIRTH THE HEAD IS NORMALLY DELIVERED FIRST THE BODY SLIDES OUT AFTER THE HEAD EMERGES A NEWBORN BABY AND A PLACENTA The placenta (afterbirth) is delivered in the third stage of birth Here the umbilical cord is still attached to baby and placenta Postpartum • Range of feelings from excited and happy to tearful • Baby blues affect 75% – Mood swings lasting ~10 days • Postpartum depression (PPD) affect 15% – Insomnia, anxiety, hopelessness – Loss of interest in the child/thoughts of harm • Sleep deprivation heightens stress • Advantages – – – – – – Breastfeeding Digestible food with antibodies Prevents uterine hemorrhage Lower SIDS Higher IQ Emotional and sensual experience Promotes bonding • Disadvantages – – – – Vaginal dryness due to decreased estrogen Temporary breast tenderness Leaking milk Harder to share feeding duties Sexual Interaction After Childbirth • Vaginal Birth – After lochia flow stops and vaginal area heals from lacerations or episiotomy – 3 to 4 weeks • C-section – When incision healed • When desire returns and it’s comfortable – Varies considerably – Often 6 to 8 weeks • Activities can include more non-coital and/or affectionate behaviors • But, expect it to maybe be pretty bad for awhile • End
