Natural cycle IVF is an IVF or ICSI cycle in which one egg is collected from your ovary during your natural menstrual cycle. Low levels of drugs may be used to stimulate egg production.
- Women with low ovarian reserve (based on hormone results FSH, AMH etc) or women who have responded poorly to previous IVF cycles with standard ovarian stimulation (sometimes called "poor responders"). For these women even though natural cycle IVF will not have a high success rate, it can be the only option before treatment with oocyte donation
- Women with extremely high risk for ovarian hyperstimulation syndrome (OHSS) or women who have previously been hospitalised due to OHSS
- Women with a contradiction to IVF drug stimulation either due to a history of cancer, medical history or an allergic reaction to medications
