In vitro fertilization (IVF) is a series of complex clinical procedures that treats infertility. Through IVF, the normal process of fertilization of the egg and sperm and implantation of the embryo is assisted outside a woman’s body, in the laboratory. It involves the removal of eggs from the ovaries, fertilizing it with sperms in the lab and introducing the embryo back into the uterus (womb). IVF treatment is given in cycles and can be a long procedure. Your chances of conceiving through IVF depend on your age and the cause for infertility.
