For in vitro fertilisation treatment, male and female reproductive cells are kept at body temperature in suitable environment for 48 hours. Approximately half of the eggs are fertilised. These fertilised eggs are called embryo and these embryos are placed to womb.
Embryos are placed by using a small catheter from cervix to uterus (embryo transfer). After these operations, approximately 50% of women experience pregnancy. However, some of these pregnancies may end with miscarriage. Approximately 40% of couples can have a child after this treatment. This ratio can go up to 70-80% in most cases.
