Document Summary

Chapter 3: biological foundations, prenatal development and birth. 120-150 males conceived for every 100 girls. 106 boy live births for every 100 girl live births. Boys have an increased frequency of c-sections needed at birth and developmental disorders. Sperm either carries and x or a y sperm this determines gender. If you have sex when a women is ovulating you have a higher chance of conceiving a boy because the sperm carrying the y chromosome swim much faster to an egg and the y chromosome is more hardier. If you have sex a few days before the woman ovulates the x chromosome sperm is hardier so they are the ones alive when the egg is released. A process designed to help couples asses the risk of having a child with a hereditary disorder. Individuals are more likely to seek genetic counselling if they know that they have a family history of genetic disorders or if they have difficulty bearing babies.
