The addition of a child to a family's home is a happy occasion. Unfortunately, some families cannot have children due to unforeseen problems and have to resort to other solutions besides natural pregnancy. Some couples adopt and other couples follow a different path; use in vitro fertilization or surrogacy. The process is complicated, unreliable, but ultimately can give parents the gift of a child they might not otherwise have had. At the same time, as the process becomes more and more advanced and scientists are able to predict the outcome of the technique, the choice of which child to be born is placed in the hands of parents. Instead of waiting to see whether the baby had the mother's eyes, the father's hair or the grandmother's heart problem, parents and doctors can select the best eggs and sperm to create the perfect baby. Many see the rise of in vitro fertilization as the second coming of the eugenics movement of the 19th and early 20th centuries. A process that can bring joy to so many parents is also seen as deciding who is capable of reproducing and which child is worthy of giving birth. According to the Centers for Disease Control and Prevention, 2.1 million married couples experience infertility issues. Infertility is defined as trying for more than a year without getting pregnant for women under 35 and trying for six months for women over 35. The cause of infertility is a male factor in a third of cases, female in another third, in 10% of cases. the cause is a combination of both male and female factors and the remaining twenty percent is not evident. IVF is a process that seeks to eliminate the problems inherent in the mother and father.
