What is Natural Cycle IVF?

Natural cycle in vitro fertilization is a type of fertility treatment which does not use fertility medications to stimulate egg production prior to embryo transfer. This method of IVF is most suitable for women who:

  • Have high levels of follicle-stimulating hormone
  • Are not able to produce several eggs during a single cycle
  • Who are at risk of ovarian hyperstimulation syndrome
  • Do not wish to take fertility medications
  • Are over the age of 35
  • Do not wish to produce multiple embryos

Natural cycle IVF procedure

The doctor will monitor egg production during a women’s natural cycle using ultrasounds and blood tests. As soon as the egg has reached a mature state, the doctor will induce ovulation, and then the egg will be retrieved. Natural cycle IVF only produced one egg at a time. The egg will be fertilized in the laboratory, and when it reaches the right stage of development, it can be transferred to the mother’s uterus. The mother uses vaginal suppositories to prepare her uterus for the embryo’s implantation.

Medicated IVF procedure

During a medicated IVF cycle, fertility medications are given to stimulate the ovaries into producing multiple eggs. When the eggs are produced, they are retrieved using the same process as natural cycle IVF. The eggs are then fertilized in the laboratory. One or more of the embryos are used for implantation. The rest of the embryos may be frozen for a future IVF cycle.

Deciding which treatment is right

Many women are not sure at the outset which treatment is right for them. There are a number of things to consider before making a decision, such as:

  • Can embryos be cryopreserved for future use? Preservation of embryos allows subsequent cycles if the first one is not successful. It also allows mothers to extend their family at a later date. Also, genetic testing can be performed on frozen embryos.
  • How much will each cycle cost? Generally, a natural cycle is less expensive than a medicated cycle because fewer medications are involved.
  • Are there any health risks involved? Women who undergo ovarian stimulation with medications may be at risk of ovarian hyperstimulation. This occurs when the body over-responds to the drugs.
  • What are the clinic’s success rates? Typically, pregnancy and live birth rates are higher with a medicated IVF cycle.
