    • Chapter Nine Designing Your Reproductive Life Plan
    • Family Planning
      • Family Planning is more than a personal and family issue
      • It has health, social, and political implications
      • Women and children have been impacted by:
          • Governments
          • Religious bodies
          • Health care options
          • Political agendas
      • Women need access to a variety of reproductive options
    • Benefits of Family Planning
      • Contributes to decreasing poverty for women
      • Provides women more time to spend on education and job opportunities
      • Reduces the number of maternal and infant mortality
      • Reduces global population
      • Reduces the number of teens who give birth (unintended and premature births)
      • Provides adolescents with more opportunities to succeed in life
    • Reasons for Selecting a Birth Control Method
      • Availability of method
      • Prevent having children
      • Reduce STD risks
      • Religious doctrine
      • Decision-making process with partner
      • Health risks
      • Financial and emotional considerations for couples
      • User effectiveness rate
    • Birth Control Methods
      • Birth control methods are all strategies used to keep from having a baby and include the following:
          • Contraceptive methods
          • IUD’s
          • Emergency contraception
          • Abortion
      • Contraceptive choices are methods that prevent fertilization of the ovum such as:
          • Hormonal methods
          • Barrier methods
          • Sterilization
      See Table 9.1 for comparisons of effectiveness and cost
    • Abstinence
      • Abstinence is the only sure method of birth control to prevent an unintended pregnancy or unwanted STIs
      • Teenagers can be sexually intimate without risking pregnancy or STIs
      • The latest trend is showing a decline in Abstinence-only programs
      • These programs are not supported by peer reviewed research for prevention of STIs, HIV/AIDS, and unplanned pregnancies
      • Furthermore, no research studies have shown abstinence only education to be consistently effective in delaying sexual activity in teens
    • Fertility Awareness Methods See illustration on next slide Offers no protection against sexually transmitted diseases or infections
      • Cycle-based method (calculating the unsafe days of ovulation)
      • Basal temperature (raise in body temperature could result in ovulation)
      • Mucus (evaluate consistency of vaginal discharge to predict ovulation)
      • Sympothermal (combines basal type and mucus together)
      • Withdrawal (not a contraceptive method) penis is withdrawn from the vagina before ejaculation
      Natural Family Planning Methods
    • Fertility Awareness (See Figure 9.1)
    • Barrier Methods
      • Barrier methods prevent sperm from reaching the fallopian tubes, either by physical or chemical means
      • Barriers include the following:
          • Spermicides
          • Condoms
          • Diaphragms
          • Cervical caps
      • Barrier methods remain popular because of the protection they provide against HIV and other STIs
    • Barrier Methods, cont’d In a recent study, women who used a condom and N-9 gel had a 50% higher HIV infection rate vs. a condom and placebo gel
      • OTC products
      Vaginal Spermicides
    • Barrier Methods, cont’d N/A Silicone cup with air valve that fits over the cervix and comes in 1 size Cervical Shield 84-97% user rate effective Soft rubber cap, must be fitted by health care professional, used with spermicide Diaphragm 87-98% user rate effective Thimble shaped device fits over the cervix Cervical Cap 78-88% user rate effective OTC product Female condom 98% user rate effective OTC product Condom with Spermicide 86-90% user rate effective OTC product Male Condom
    • Hormonal Contraceptives
      • Hormonal contraceptives are convenient, effective, and reversible
      • However, they provide no protection against HIV and other STI’s
      • They are solely intended to prevent pregnancy
      • The primary methods available are:
          • Oral contraceptives
          • Norplant
          • Injections i.e. Depo-Provera, Lunelle
          • Patch
          • Ring
    • Oral Contraceptives
    • Oral Contraceptives
      • Oral contraceptives are considered the second most popular form of birth control in the United States
      • Works by primarily inhibiting ovulation through suppressing FSH and LH
      • Types:
          • Combination pills that contain estrogen and progestin
          • Progestin only types (mini-pill)
    • Health Benefits of OC’s
      • Research suggests that Oral contraceptives provide the following benefits:
          • Protection against epithelial ovarian and endometrial cancer
          • Lowered risk for ectopic pregnancies and PID
          • Lighter and less painful menstrual flow
          • Decreases in iron deficiency anemia
    • Health Risks Associated with OC’s
      • Estrogen use is associated with the following side effects:
          • Nausea
          • Breast pain and soreness
          • Fluid retention
      • Progestin-only pills are associated with:
          • Increased irregular menstrual cycles
          • Vaginal bleeding
      • Other risks with OC’s include:
          • Blood clots
          • Strokes
          • Changes in bone density
          • Reproductive cancers
    • Other Forms of Hormonal Contraceptives
      • Yasmin (contains synthetic progestin, drospirenone)
      • Transdermal Patch (skin patch containing progestin/estrogen)
      • NuvaRing (vaginal insert containing progestin/estrogen)
      • Lunelle (monthly hormone injection)
      • Implanon (progestin-only subdermal implant)
      • Depo-Provera (progestin injection once every 3 months)
    • Emergency Contraception
      • In 1998, the FDA approved the first combination pill (Preven)
      • A year later, a progestin pill was developed (Plan B)
      • ECP’s reduce the risk of pregnancies by delaying or inhibiting ovulation when taken within 120 hours of unprotected intercourse
      • Effective rates improve when taken earlier vs. later
      • ECP’s do not induce a medical abortion or affect the developing pre-embryos or embyros
      Emergency IUP insertion is also considered a choice within 5 days of Unprotected intercourse and reduces pregnancy risk by 99.9%
    • Contraindications for Hormonal Methods
      • If woman is pregnant
      • Active liver disease
      • Heart problems
      • Breast cancer
      • diabetes
      • Hypertension
      • Migraine headaches
      • Epilepsy
      • History of blood clotting
    • Intrauterine Devices
      • The WHO and the AMA have called the IUD one of the safest, most effective and least expensive reversible methods of birth control available
      • Past history with a faulty brand (Dalkon Shield, 1974) contributed to its lack of popularity in the U.S. as well as its stigma of being associated with abortion and PID’s
      • The method works by reducing the amount and ability of sperm to reach the egg
      • Other forms of IUD’s contain hormones, which allows the female to wear the IUD longer compared to others
    • Sterilization
      • Vasectomy – separation of the vas deferens
      • Tubal ligation – separation of the fallopian tubes
    • Maternal Mortality
      • Maternal mortality is defined as the death of a woman while pregnant
      • They are divided into direct and indirect obstetrical deaths
          • Direct: account for 80% of deaths and results from complications such as incorrect treatment, labor, pregnancy, or omissions, commonly due to hemorrhage
          • Indirect: result from previous existing diseases or diseases caused by the physiological complications of pregnancy e.g. anemia
      • The best mechanism to prevent maternal deaths is to improve the status of women
    • Infant Mortality
      • Infant mortality is defined as the deaths of infants under 1 year while neonatal mortality is under 28 days
      • Race and education are important indicators for infant mortality
      • The primary causes for neonatal and infant mortality are:
          • Congenital anomalies
          • Pre-term/low birth weight
          • SIDS
          • Respiratory Distress
          • Complications of Pregnancy
    • Pre-Pregnancy Planning
      • Non-drug use
      • Nutritional planning
      • Exercise
      • Time lapse of one menstrual cycle between contraceptive use and conception
      • Immunizations
      • Folic acid supplements
      • Quit smoking
      • Avoid alcohol beverages
      • Avoid OTC drugs
      • Avoid mega-dosing on nutritional supplements
      Pre-pregnancy planning encompasses the following:
    • Conception
      • Pregnancy begins with the union of the female egg and the male spermatozoa
      • A one cell zygote is formed, containing characteristics of both parents
      • The fallopian tubes provide the environment where cell division begins
      • After 3 days, the fertilized ovum is transported to the uterus
      • Once the chorionic villi cover the ovum, hCG (human chorionic gonadotropin) supports the endometrial growth
    • Amnion
      • The amnion surrounds the embryo before it starts to evolve
      • The amnion cavity is a fluid filled space between the amnion and the embryo
      • It keeps the fetus at an even temperature, cushions, and provides nourishment
      • By the 4 th month, it can be sampled (amniocentesis) for possible genetic abnormalities
    • Placenta
      • This is formed during the 3 rd month
      • The function is to supply food to the fetus and connects to the fetus through the umbilical cord
      • The placenta does the following tasks:
          • Transfer gases and nutrients
          • Excretes waste
          • Transport heat
          • Produces various proteins and hormones
          • Brings maternal and fetal blood close together but are completely separate
    • Early Signs of Pregnancy
      • A missed period
      • A light period or spotting
      • Tender, swollen breasts
      • Fatigue
      • Upset stomach
      • Vomiting
      • Feeling bloated
      • Frequent urination
      Most home pregnancy tests measure Human Chorionic Gonadotropin (hCG) to determine whether you are truly pregnant. Most tests are accurate.
    • Fetal Development Table 9.2 (First Trimester)
      • The heart beings to beat
      • Bones have appeared-head, arms, fingers, legs, and toes
      • The major organs and nervous systems are formed
      • The placenta is formed
      • Hair is starting to grow
      • 20 buds for future teeth have appeared
    • Fetal Development Table 9.2 (Second Trimester)
      • The fetus grows quickly from now until birth
      • The organs are developing further
      • Eyebrows and fingernails form
      • The skin is wrinkled and covered with fine hair
      • The fetus moves, kicks, sleeps and wakes, swallows, can hear, and can pass urine
      • By the end of this time, the fetus is 11-14 inches long and weighs about 2-2.5 lbs.
    • Fetal Development Table 9.2 (Third Trimester)
      • The fetus kicks and stretches, but as it gets bigger it has less room to move
      • Fine body hair disappears
      • Bones harden, but bones of the head are soft and flexible for delivery
      • The fetus usually settles in a good position for birth
      • At 40 weeks, the fetus will be full term. It is about 20 inches long and weighs 6-9 pounds
    • Pre-natal Care (First initial visit)
      • Discussion of maternal nutritional needs, exercise, and drug use
      • History of maternal, paternal, and family
      • Physical exam including ht./wt. and blood pressure
      • Exam of the reproductive organs
      • Estimation of the due date
      • Blood, urine ,and pap tests
    • Pre-natal Care (subsequent visits)
      • Physical exam including ht./wt. and blood pressure
      • Fetal heartbeat, growth, and position
      • Urine test for protein and sugar
      • Possible ultrasound, chorionic villus sampling, maternal serum screening, amniocentesis, anon stress test, a contraction stress test and a biophysical profile
      Weekly prenatal checkup are recommended after week 36
    • Labor Signs
      • Braxton Hicks contractions increasing in frequency and intensity
      • Lightening occurs
      • Amniotic sac ruptures
      • The 3 stages of labor are:
            • Uterine contractions 15-20 mins. w/ “bloody show” with full cervix dilation
            • Crowning of the fetus’ head to fetal expulsion
            • Placental separation and expulsion
    • Birthing Options
      • Midwives
      • Doulas
      • In-Hospital Deliveries
      • Birth Centers
      • Birthing Positions
    • Breast-feeding
      • Breast-feeding has prevented nearly 6 million infant deaths each year world-wide
      • Advantages are:
          • Inexpensive
          • Better nutritional quality
          • Ability to act as a birth control measure to limit fertility
          • Reducing ovarian and premenopausal breast cancer
          • Contains colostrum (initial milk produced by the mother) which helps fight infections
    • Potential Problems During Pregnancy
      • Ectopic Pregnancy
          • Tubal pregnancy
          • Occurs due to narrowing of the fallopian tubes
          • Can cause infertility and mortality
      • Hypertensive disorders
          • Preeclampsia-elevated blood pressure due to edema and/or proteinuria
          • Eclampsia-same as above except it progresses to convulsions and/or coma
    • Infertility
      • Health providers should determine the cause of having difficulty conceiving
      • Primary infertility is the inability of a woman to become pregnant within a year of having unprotected intercourse
      • Secondary infertility is the inability to carry the pregnancy to full term
      • The most common reasons for primary infertility in women are failure to ovulate or a damaged uterus or fallopian tube while men have low sperm or abnormal counts
    • Assisted Reproductive Technology (ART)
      • In vitro fertilization (IVF)
      • GIFT (gamete intrafallopian transfer)
      • ZIFT (zygote intrafallopian transfer)
      • ICSI (intercytoplasmic sperm injection)
        • The majority of these procedures are IVF (75%)
        • 69% were performed on women aged 30-39
        • The remainder were common among women aged 40 years or older
    • Other Procedures Used to Promote Motherhood

      • First Trimester Procedures
        • Menstrual extraction – withdraw endometrial tissue during the 4 th -6 th week
        • Vacuum aspiration – 6 th -9 th week procedure performed the most by dilating the cervix and removing uterine contents
        • D&C (Dilation & Curettage) - performed during 9 th -14 th week; dilation of cervix and scraping the wall of the uterine
        • RU486 (Mifepristone) – blocks the action of progesterone and doesn’t allow implantation to occur
    • Abortion – Termination of a Pregnancy, cont’d
      • Second Trimester Procedures
        • D&C (Dilation & Curettage) - performed during 13 th -15 th week; cervix is dilated and contents are removed by suction
        • Hypertonic Saline procedure – 16 th week procedure where saline is administered and the uterus is caused to expel contents
        • Prostaglandin procedure – hormones cause contractions to expel uterine contents
    • Adoption
      • Adoption is an alternative to assisted reproduction or abortion
      • Adoptions can be ‘open ‘ or ‘closed’`
      • Couples who are making the decision have a variety of issues to consider
      • Services can vary from matching children and adoptive parents to educational and support services throughout the parenting years
