NATURAL IVF does not require a woman to take medication to stimulate production of eggs. Instead, a clinic tracks a woman's own cycle and when an egg is ready for ovulation, it is collected.
This involves using a simple surgical procedure to maximise the chances of fertilisation. The egg is then fertilised in the lab with the use of technology and transferred to the woman two days later. If unsuccessful it can be attempted again during her next cycle.
The fact that it is medication-free means it is less expensive than conventional IVF.
