In vitro fertilization (IVF) is a type of fertility treatment that involves the handling of eggs or embryos and sperm outside the body in a laboratory dish. It is a complex series of procedures that can lead to a pregnancy and is used to treat infertility, a condition in which couples cant get pregnant after at least a year of trying for most couples. IVF can also be used to prevent passing on genetic problems to a child. During IVF, mature eggs are collected from ovaries and fertilized by sperm in a lab. Then, one or more of the fertilized eggs, called embryos, are placed in a uterus, where babies develop. The process of IVF can take about 2 to 3 weeks, and sometimes these steps are split into different parts and can take longer. IVF is the most effective type of fertility treatment that involves the handling of eggs or embryos and sperm, and it is one of the most successful treatment options for managing infertility regardless of its cause.
