6 © 2009 McGraw-Hill Higher Education. All rights reserved. Obstacles to Fertilization Acid level in the vagina Cervical mucus thickness Location of cervical entrance for sperm Location of the correct fallopian tube for sperm Distance sperm travels Motility of sperm

7 © 2009 McGraw-Hill Higher Education. All rights reserved. Aids to Fertilization 200-500 million sperm cells are deposited into the vagina during ejaculation Sperm are deposited near the cervical opening Male accessory glands help make the semen nonacidic Uterine contractions aid sperm movement in the proper direction Sperm cells move fairly quickly Sperm can live for days Cervical mucus is thin and watery at the time of ovulation

9 © 2009 McGraw-Hill Higher Education. All rights reserved. Signs of Pregnancy (Presumptive) Missed menstrual period after sexual intercourse the previous month Morning sickness Increase in size and tenderness of breasts Darkening of the areolar tissue around the nipples

10 © 2009 McGraw-Hill Higher Education. All rights reserved. Signs of Pregnancy (Probable) Increased frequency of urination Increased in the size of the abdomen Cervix becomes softer by the sixth week Positive pregnancy test

11 © 2009 McGraw-Hill Higher Education. All rights reserved. Signs of Pregnancy (Positive) Determination of a fetal heart beat Feeling of the fetus moving (“quickening”) Observations of the fetus by ultrasound or optical viewers

13 © 2009 McGraw-Hill Higher Education. All rights reserved. Intrauterine Development Three trimesters (13 weeks each) First trimester Zygote Blastocyst Embryo Fetus (after 8 weeks) Second trimester: Organs develop, fetal heartbeat and bone structure evident, prominent weight gain in the mother Third trimester: Fetus increases weight from 2-3 pounds; absorption of major nutrients allowing increased growth and weight

14 © 2009 McGraw-Hill Higher Education. All rights reserved. Maintaining a Healthy Pregnancy Arrange for prenatal care Consume a well-balanced diet Take a supplement with folic acid Exercise according to your physician’s recommendation Avoid and treat infections Avoid alcohol, tobacco, and other drugs Limit your caffeine intake Stay away from x-rays, hot tubs, saunas, toxic chemicals

Three Stages of Labor Effacement/dilation of the cervix: Uterine contractions thin the cervix and enlarge the cervical opening Cervix opens to 10 cm during this stage Delivery of the fetus: Uterine contractions are aided by mother’s voluntary contractions of abdominal muscles Fetus moves through the birth canal Delivery of the placenta: Placenta detaches from uterine wall

17 © 2009 McGraw-Hill Higher Education. All rights reserved. Cesarean Deliveries (C-section) Fetus is removed from the uterus through the abdominal wall Possibly due to one or more of the following factors: Fetus is improperly positioned Mother’s pelvis is too small Fetus is especially large Fetus shows signs of distress Umbilical cord is compressed Placenta is being delivered before the fetus Mother’s health is at risk

19 © 2009 McGraw-Hill Higher Education. All rights reserved. Testing for Fetal Abnormalities Ultrasound High-frequency sound waves Quad marker screen Blood test that predicts the likelihood of certain problems Amniocentesis Insertion of a long needle through the abdomen to extract amniotic fluid Chorionic villus sampling Extraction of cells from the placenta

20 © 2009 McGraw-Hill Higher Education. All rights reserved. Complications in Pregnancy and Childbirth Ectopic pregnancy: Embryo implants in the fallopian tube Miscarriage: Usually due to congenital abnormalities Gestational diabetes: Temporary condition in which the mother’s body doesn’t produce enough insulin Hyperemesis gravidarum: Excessive vomiting Preeclampsia: Elevated blood pressure Eclampsia: Final stage of preeclampsia, which can include convulsions and coma

21 © 2009 McGraw-Hill Higher Education. All rights reserved. Complications in Pregnancy and Childbirth (cont.) Intrauterine growth retardation (IUGR): Insufficient growth of the fetus due to genetic factors, maternal disease, or malnutrition Premature rupture of the membranes (PROM): Rupture of the chorionic membranes (“breaking of the water”), which increases risk for infection Premature labor: Labor that begins before the fetus is full-term Fetal distress: Fetal problems such as a lack of oxygen caused by a variety of factors

22 © 2009 McGraw-Hill Higher Education. All rights reserved. Causes of Infertility Low sperm count Poor sperm motility Sperm abnormalities Lack of ovulation Obstruction of fallopian tubes

26 © 2009 McGraw-Hill Higher Education. All rights reserved. Cloning Techniques Procedures involve the following: Surgical removal of an egg from female donor Nucleus of the egg is removed Cell is taken from a cloning subject (male/female) Through an electrical jolt, the cell is fused with the enucleated egg, creating a clonal zygote Embryo is implanted in the womb of a surrogate mother After nine months, a genetically matched reproduction is born

27 © 2009 McGraw-Hill Higher Education. All rights reserved. Cloning Reproductive cloning Not yet accomplished Banned in selected countries and states Therapeutic cloning Can be used to create stem cells
