Re: Mini / Mild IVF

I think all the clinics in NZ will offer mild stimulation for IVF for private treatment if requested. It will not be cost effective for public treatment in most cases, since the aim of public treatment is to maximise your chance of a baby within acceptable safety limits.

In general ovarian stimulation for IVF in NZ is milder than in the USA, and more like that in Europe and Australia.

Some people consider alternatives to conventional stimulation because they do not respond well to conventional stimulation. In this case it is about using cheaper drugs to try to obtain a similar outcome, since it is the woman's ovarian reserve which is limiting response to drugs.

It is important to remember that it can be difficult to control the number of eggs the body produces in response to ovarian stimulation drugs - halving the dose doesn't halve the number of eggs. Most people have a threshold below which the drugs don't have any effect, while above the threshold there is not much control over the number of follicles that grow. There is also a lot of variation from one IVF cycle to the next in the same woman using the same dose of drugs and the same stimulation protocol. As a rule of thumb, you can expect to get the same number of eggs the in next IVF cycle plus or minus 3 80% of the time. This means that if you got 8 eggs the first time, you still have a 10% chance of getting more than 11 (=8+3) the next time, and a 10% chance of getting fewer 5 (=8-3) the next time.

Hope this helps. John Peek, Moderator.
