Natural IVF is also known as Natural Cycle IVF(in vitro fertilization). Natural IVF emphasizes on quality of egg, rather than quantity of eggs. It is an in vitro fertilization but without excessive use of medication to stimulate the ovary to make multiple eggs. It is a gentler fertility treatment on the body. It is the closest or so to say nearest IVF treatment to natural fertilization. No or minimal fertility drugs/ injections are used in the Natural IVF.
Natural IVF is a proposed IVF treatment for reducing the risk of multiple pregnancies, eliminating the cost and risk associated with fertility drugs, and reducing the time commitment needed. Natural fertility involves collecting one egg that has been naturally selected and matured by the body, and fertilized egg (embryo) is placed back on the womb.
Natural IVF is the oldest fertility treatment being used. Dr. Robert Edwards and Dr. Patrick Steptoe were the first to use Natural IVF to conceive baby, named Louise Brown. Louise Brown is also the world’s first test-tube baby. As the infertility field develop, more and more fertility drugs were used to produce more number of eggs during one cycle. The protocol to use more and more fertility drugs became today's conventional IVF. Keeping in the mind the risk associated with conventional IVF, many physicians begins to practice natural IVF. Dr. Osamu Kato was considered the hand behind the movement to use natural protocol for IVF.
Due to the use of no or minimal fertility drugs, the probability of getting pregnancy is lesser as compared to other IVF treatment.
