- T/F: Transfer of 5 day old blastocysts allows nature to weed out most chromosomally abnormal embryos.
- From the Sandelowski article, “Alone in a Crowd” infertile couples
- may or may not want to discuss fertility, and may feel isolated from people with children.
- T/F: Post-Coital Test is NOT a method of at home fertility monitoring.
- STI’s may cause
- PID, no symptoms, scarring and irreversible damage, and infertility.
- T/F: Infertility is a 1/3 male issue, 1/3 female issue, and 1/3 an undeterminable issue.

- unlimited amount. discrimination of clinic.
- T/F: • it is possible for post-menop. woman to become preg. thru building endro. lining and egg transfer.
- what is US legal age limit for ARTs?
- none. clinical discretion.
- method of sex selection
- injecting sperm into the egg's cytoplasm.
- T/F: o The mother and the fetus share the same blood supply
- o The role of the placenta during pregnancy is to provide oxygen to the fetus, nutrients to the fetus, and can filter toxins and microbes to protect the fetus.
- Group B Strep
- can be treated during labor with an IV of: antibiotics.
- Risk of invasive prenatal testing
- why was prenatal care developed?
- to diagnose eclampsia and pre-eclampsia.
- placenta previa
- -painless bleeding
-IUGR caused by placenta previa is due to poor placental perfusion.
- a high level of glucose
- Gestational Diabetes (GDM)
- may result in neonatal hypoglycemia, childhood obesity
- PIH (pregnancy induced hypertension)
- disorders include elevated blood pressure.
- Estimated Due Date
- Last Menstrual Period
- definition: pregnant
Primigravida: first pregnancy
Multigravida: second, third…pregnancy
- Definition: a women who has given birth.
Nullipara: never given birth
Primipara: first birth
Multipara: second, third…birth (includes twins)
- when mother feels fetal movement
- -Thickens the endometrium (vascular)
-Supresses development of a new follicle…
-Inhibits uterine contractions
- Embryonic/Fetal Highlights
- 1st Trimester: heart develops first, beats at ~5 to 6 weeks
All major organs grossly developed by week 10
2nd Trimester: detailed development of organs and fetal growth
Hearing ~ 26 weeks
Eyes reopen ~ 26 weeks
3rd Trimester: fetal growth continues
- Which changes occur during the third trimester?
- Braxton-Hicks contractions. Painless cramps that prep women for real labor pains.
- Sex selection can be achieved using
- Microsort, pre-implantation genetic diagnosis, or an ultrasound at 16-20 weeks
- nytimes article
- • A new prenatal test for down syndrome is being developed to detect abnormal fetal cells in maternal blood.
- Screening Test
- • A screening test (opposed to a diagnostic test) will reveal the chances of a possible abnormality.(opposed to a diagnostic test)
- What test can be conducted for Down Syndrome?
- • An ultrasound at 9-13 weeks to measure nuchal folds with an AFP test can screen for Down Syndrome.
- Fetal blood sampling
- performed at 18 weeks or later to detect chromosomal disorders, infections, of fetal blood disorders.
- is performed between 15-17 weeks to reveal chances a fetus may have a neural tube defect or a chromosomal abnormality.
- DIAGNOSTIC TEST
- determines with a relative certainty whether a fetus has a specific problem or abnormality.
- Prenatal Tests
- -Urine Test
-Maternal Blood Test
-Chorionic Villus Sampling (CVS)
-Fetal Blood Sampling (PUBS)
-New and emerging technologies…
- The “AFP” screen
- AFP (alpha-fetoprotein)
Levels are calculated with maternal age, gestational age and determine personal risk estimate often reported as a ratio
- Types of Ultrasound
- Transvaginal : early pregnancy
Standard : 2-D image
Advanced : targets a suspected problem/more sophisticated equipment
Doppler : detects frequency changes (blood flow)
3-D : special probes w/ software to generate 3-D images
4-D or Dynamic 3-D : 3-D in motion
Fetal Echocardiography: heart anatomy and function
- Why do an amniocentisis?
- Neural Tube Defects (NTD): spina bifida, anencephaly
Chromosomal disorders: Trisomy 21 (Down syndrome), 13, 18, Fragile X
Genetic disorders: cystic fibrosis, Turner syndrome.
- Amniocentisis Risks
PROM (premature rupture of membranes)
Clubfoot w/ early amnio 1/1000
- Chorionic Villus Sampling (CVS)
- TWO METHODS:
Transcervical: ( most common method)
US, thin catheter to suction chorionic villi cells
Similar to amnio
larger sample, faster results.
- Fetal Blood Sampling (PUBS):
- performed at 18 weeks or later
US to identify structures
a thin needle through abdomen and uterus to umbilical cord.
Small amt of cord blood extracted
results usually within 72 hours
If diagnostic information cannot be obtained through amnio, CVS, or ultrasound, or the results of these tests were inconclusive
*Blood disorders (i.e. fetal hemolytic disease.)
*Fetal infection (i.e. toxoplasmosis, rubella)
*Fetal platelet count in the mother
- A reactive non-stress test includes
- FHR 130-140 WITH ACCELERATIONS.
- o After a non-reactive NST, what should happen next?:
- A biophysical profile.
- o Why would FHR accelerations NOT occur during a non-stress test (NST):
- fetal immaturity.
- The leading cause of prematurity
- “Choosing Naia”?
- -Down syndrome was the parents primary concern
• The first indication that Naia had an abnormality was diagnosed by an ultrasound.
- Spina Bifida
- a neural tube defect (NTD) which can be diagnosed by ultrasound during pregnancy.
- options for women carrying a baby with Down Syndrome
- abortion, adoption,raising the child.
- What is the role of the placenta during pregnancy?:
- Provides nutrients to fetus and filters toxin.
- Bainbridge Article states what...
- sperm are necessary for placenta development.
- ovulation occurs ____ after LMP
- 2 weeks
- what test can provide quantitative results?
- serum (blood) test detects levels of hcG in blood.
- fetal pain perception is unlikely until the third trimester.
- Methods of emergency contraception include
- post-coital insertion of IUD
- Leading jurisdiction that solidified abortion rights in US
- Roe vs. Wade, 1973
- Abortion Options by Trimester
*Methotrexate-Orally up to 6 weeks
*Mifepristone - Orally up to 9 weeks (RU486)
* MVA: Manual Vacuum Aspiration
* D&C: Dilation and Suction Curettage
*D&E: Dilation and Evacuation
- Multifetal Pregnancy Options
- *Wait and See: 10-30% will spontaneously reduce
+Elective reduction: Usually done 9-12 weeks
-Ultrasound used to guide needle to inject Potassium chloride (vaginal or abdominal)
-17% result in total pregnancy loss
-Preterm labor occurs in 75% of MFR pregnancies.
+Carry higher-order multiple pregnancy
- T/F: - In the US, abortion in the first trimester is a safe and legal option.
