Modified 'Mild' IVF: Why It's Not Suitable for Everyone

This information was correct at the time of publishing. It may not reflect our current practices, prices or regulations.

With newly revealed statistics showing that a ‘natural’ type of IVF fails in 90% of cases, is it worth you trying to get pregnant using alternative IVF methods? 

Many clinics offer variations of IVF that are promoted as more ‘gentle’. These range from full natural cycle IVF, which relies solely on the egg you naturally ovulate each month, to Modified Natural Cycle or ‘mild’ IVF

But the truth is that these types of IVF treatments are only suitable for certain cases, and should not be offered to all patients regardless of diagnosis as a ‘safer’ alternative to conventional IVF, which has a much higher success rate.

Who is suitable for Modified Natural Cycle IVF? 

At Manchester Fertility, we only offer Modified Natural Cycle IVF. It’s simply a stimulation protocol where lower doses of fertility drugs are used to stimulate the ovaries compared to standard drug protocols.

This protocol is designed for patients with extremely low ovarian reserve – which means a very low number of eggs in the ovary to begin with - and high doses of drugs would not yield any more eggs than with the modified natural regime. 

This type of stimulation protocol is used if they want to try to conceive with their own eggs, instead of using donor eggs. Modified Natural IVF may also only be advised if you’ve had failed conventional stimulation protocols.

Our open and honest approach to your IVF treatment

Success rates however using this method are very low, and you may need a number of cycles to try to achieve pregnancy. We would always be realistic with you about whether Modified Natural IVF is likely to be successful for you, and which treatment options give you the best chance of a baby – even if that is through the use of donor eggs.

Using fertility drugs: Effective and safe IVF treatment

If you’re considering Modified Natural IVF simply because you’re concerned about using fertility drugs and their potential side effects, you can be assured that at Manchester Fertility all fertility drug regimens are personalised and tailored to each patient, with a focus on the quality of eggs - not the quantity.

This individualised approach, combined with monitoring throughout from our team, means your IVF stimulation phase is safe and effective with complications such as Ovarian Hyperstimulation Syndrome significantly reduced.
