Document Summary

Infertility: not being able to get pregnant after a year of trying, stems from a variety of causes (sti"s, varicocele, equally attributed to men and women, artificial insemination, also called intrauterine insemination. In vitro fertilization: several eggs are removed from a woman"s ovary and manually combined with sperm in a lab, returned to uterus in hopes that one egg will implant, prenatal stages, germinal period: 1st and 2nd week. Zygote divides many times through mitosis, forming the blastocyst: between 8%-30% of pregnancies go unrecognized during this period, and miscarriage, embryonic period: 3rd to 8th week. Formation of most of the organs: organogenesis: amnion, watertight membrane fills with fluid that protects the embryo, chorion. In 1/2000 pregnancies, the neural tube fails to fully close. Influenced by genetic instructions and the biochemical environment: differentiation, every neuron starts with the potential to become any specific type pf neuron, what each neuron becomes depends on where it migrates, age of viability.
