  1. Pregnancy 101

  2. Becoming Pregnant • Conception is based on an intricate series of events • Every month, hormones from your pituitary gland stimulate your ovaries to release an egg, or ovulate. This often happens around day 14 of the menstrual cycle, although the exact timing may vary among women or even from month to month.

  3. Female sex cell –The ovum • Contains 23 chromosomes • Released once a month – called ovulation • Females are born with the amount of eggs they have for life.

  4. The ovum Once the egg is released, it travels to the fallopian tube. The egg has about 24 hours to unite with a sperm Ovary releasing eggs.

  5. Male sex cell – The sperm head • Contains 23 chromosomes • Males begin sperm production at puberty • 400 to 500 million sperm are released at one time nucleus tail

  6. Sperm cells can survive in your reproductive tract for two to three days Sperm trying to fertilize the ovum.

  7. The sperm Sperm and egg Head Once one sperm reaches the inside of the egg, the tail breaks off and the head “explodes” to release its DNA material. Tail

  8. Conception (fertilization) • The union of an ovum and sperm. • The mass of cells is called a zygote,a fertilized egg.

  9. Gender Determination Father X Y Mother X X Son X Y Father X Y Mother X X Daughter X X

  10. Fertilization Fertilization occurs inside the fallopian tube. In vitro fertilization

  11. Ectopic pregnancy • This occurs when the fertilized egg does not travel down the fallopian tubes to connect to the uterus. • Instead it stays in the tube and begins to grow. • This is a serious, life threatening condition Baby removed from the fallopian tube.

  12. Ectopic pregnancy with twins Twins Blood Clot

  13. 3 stages in fetal development • Zygote – 10 days • Embryo – 2 weeks – 8 weeks • Fetus – 8 weeks to birth

  14. Period of the ZYGOTE • The first stage in the development of a baby. • Lasts approximately 2 weeks. • Attaches to the uterine lining.

  15. Endometrium - Uterine lining • Usually shed monthly, if a woman does not get pregnant. • Provides a soft, warm bed and food for the fertilized egg.

  16. Period of the EMBRYO

  17. The Embryonic stage • This is the 3rd to the 8th week of pregnancy. • The placenta and umbilical cord are formed. • The embryo is surrounded by amniotic fluid.

  18. The placenta • Attaches the amniotic sac around the embryo to the uterus. • Delivered after the baby and examined.

  19. Placenta Previa • This is a condition where the placenta moves and covers the opening of the uterus. • There may be spotting or bleeding. • Usually results in a cesarean birth.

  20. Placental Abruption

  21. The umbilical cord • The tube that connects the placenta to the embryo. • Carries nourishment and oxygen to the baby and takes waste products away from the baby.

  22. Period of the FETUS • The third and longest stage of baby’s development. • Begins 8th or 9th week and lasts until birth.

  23. The amazing fetus • The fetus can do a surprising number of things like: • Suck its thumb • Cough • Sneeze • Yawn • Kick, and hiccup • Even cry

  24. Ultrasound picture of fetus

  25. Fetus in utero At the beginning of this trimester, all organs and body parts have begun to develop. By the fourth or fifth month, kicking and other movements can be felt by the mother.

  26. Surgical Procedure BABY’S ARM UTERUS

  27. Trimesters • First trimester – Months 1-3 • Second trimester – Months 4-6 • Third trimester – Months 7-9

  28. First Trimester • Some early signs of pregnancy are missed menstrual period, fatigue, abdominal distention and breast enlargement. • Fetus is most susceptible to damage from toxins, drugs, and infections.

  29. Three screening tests can be done to determine risk of genetic defects Plasma protein hCG ultrasound test for fetal nuchal translucency (NT) Tests – first trimester

  30. Second trimester – Month 3-6

  31. Tests – Second Trimester • Alpha-fetoprotein • Abnormal levels of AFP may signal the following:  • open neural tube defects (ONTD) such as spina bifida • Down syndrome • other chromosomal abnormalities • defects in the abdominal wall of the fetus • twins - more than one fetus is making the protein • a miscalculated due date, as the levels vary throughout pregnancy • hCG • Estriole • Inhibin

  32. Amniocentesis A fluid sample is taken from the amniotic sac for genetic testing

  33. Chorionic villus sampling (CVS) • A sample of placenta tissue is taken for genetic testing

  34. Other tests • Glucose tolerance tests • Tests for gestational diabetes, done around 24-28 weeks • Fetal monitoring • Baby’s heart rate is checked for abnormalities • Group B strep culture • strep infection during birth can be life-threatening – done around 37 weeks

  35. Third trimester – Month 6-9
