What is Modified Natural Cycle IVF?
Modified Natural Cycle IVF gives lower doses of fertility medication than conventional IVF. The drug dosage is enough to encourage at least one follicle to develop and to promote egg growth. As in traditional IVF, once your eggs are ready an injection of hCG is given to trigger egg maturation, followed by egg collection.
To help support your body and implantation of the embryos after transfer, progesterone supplements are also given.
At KNH Fertility Centre we only recommend Modified Natural Cycle IVF for very few patients because of its high cancellation and very low success rates.
Modified Natural Cycle IVF may be of benefit if:
- You are over 43 years old
- You’ve responded very poorly to IVF stimulation
- Your results show you have a very low AMH level
Disadvantages of Modified Natural Cycle IVF
It’s important to remember that even with a modified approach, there is a much higher risk compared to conventional IVF that your treatment cycle will be stopped for poor response, no eggs will be collected, of failed fertilisation or embryo development. You will not have as many eggs to fertilise, and resulting embryos to transfer, through Modified Natural Cycle IVF compared to conventional treatment. You are also very unlikely to get any embryos for freezing.
So Modified Natural Cycle IVF isn’t something that’s suited for every patient. We will discuss with you whether it is something you could consider, based on your individual test results and previous treatment history. We would only recommend it as an option if we think it gives you a good chance of success.
