How is test tube baby done?

Answer 1

When the woman is ovulating doctors retrieve her eggs. They do this by using an ultrasound needle that pierces the vaginal wall to the ovaries, which they can take out remove the eggs. Usually ten to thirty eggs are retrieved. The eggs are then prepared for fertilisation. Meanwhile, semen is being prepared, by being separated from the seminal fluid. Then, the sperm and egg are incubated together in a dish that is designed to hold growing cells. Usually the egg is fertilized after eighteen hours. Or the sperm could be injected directly to the egg. The fertilized egg is left for two days until it has several cells. Embryos are then transferred into the woman. Depending on the age of the woman the number of embryos vary. For older woman about three embryos are placed. The embryos are transferred through the woman's uterus with a thin catheter.
