Mark Perloe, MD Atlanta, 404-843-2229 Learn about the factors that can adversely affect fertility and the tests that can help pinpoint problems. Fertility treatment options including IVF and other high tech options are presented.

11. Blastomeres undergo compaction and form morula. Gap junctions and tight junctions will form placenta. The cells gain distinct polarity (i.e. have inside and outside faces) and flatten against each other. Embryo growth
13. Fertilization occurs in the ampulla of the oviduct, implantation in the uterus. Motile systems are important: cilia and smooth muscle. The Fallopian tube produces secretions which control and provide a vehicle for transport. Control over embryo transport may also operate at the ampullary isthmic junction and at the utero-tubal junction. Embryo transport
14. Hatching from zona The zona pellucida must be lost before the embryo can contact the uterine epithelium. Observations in vitro suggests that the blastocyst squeezes out of fractures in the zona (“hatches”). Identical twins may be produced if the embryo breaks into two during this process. Empty zona Zona free blastocysts

16. The syncytiotrophoblast proliferates and invades the extracellular matrix of the stroma. Cytotrophoblast cells migrate between the syncytia, followed by fetal stroma - leading to placental villi. Implantation

21. Age related infertility Reduced pregnancy rates Increased miscarriage rates Increased risk fetal anomalies
22. Pregnancy, Live Birth, and Singleton Live Birth by Age,* 2001 *For consistency, all rates are based on cycles started.
25. Sperm Chromatin Structure Assay SCSA®/SDFA test is a good predictor, relative to other sperm measures, for the clinical diagnosis of male infertility
39. What do we know about pregnancy losses?? 6 20 40 Weeks gestation 100 50 % Pregnancies can easily be recognized clinically by 6 wks. Ovulation rates are high! So probably are fertilization rates! Early human embryos may show a high incidence of developmental abnormalities. 10-15% of of all clinically recognised pregnancies are lost in the 1st trimester; 2-3% are lost later. 50% of these losses have cytogenetic abnormalities. 1/3 of all pregnancies are lost soon after implantation - before they are clinically recognised.
58. Success Rates: What do they mean? Pregnancies per cycle Live births per retrieval Live births per cycle Live births per transfer Singleton live births per transfer Singleton live births per cycle
61. Live Birth Rates by Age and History of Miscarriage, with No Prior Births,* 2001 *Women reporting only previous ectopic pregnancies or pregnancies that ended in induced abortion were not included in the above statistics.
62. Live Birth Rates by Woman’s Age and History of Previous ART Cycles, 2001
63. Live Births per Transfer and % Multiple Births in Women <35 by Number of Embryos Transferred, 2001 (100.0)* (59.3)* (39.6)* (53.4)* (38.8)* (7.8)* (49.1)* (41.3)* (9.6)* (43.3)* (46.8)* (9.9)* *Percentages of live births that were singletons, twins, and triplets or more are in parentheses. Note: In rare cases a single embryo may divide and thus produce twins. For this reason a small percentage of triplets resulted when two embryos were transferred. 30.0 51.7 46.9 42.9 43.1 (1.2)*
