In vitro fertilisation (IVF) is a technique by which fertilization occurs outside the body outside the body: in vitro ("in glass"). The woman's ovaries and uterus are stimulated artificially, ova are removed surgically and added to a liquid medium with sperm in a laboratory. The resulting embryos are cultured for 2-6 days at which point they may be transferred to the woman's uterus or frozen, pending delayed embryo transfer.
