Hi Shazbub,
I haven't really got much experience behind me but had my first ever assisted conception cycle in November with ICSI. I had gonal-F and started on 300 units. At my first blood test my levels were still base line and I'd bleed for about 2 days, so they increased the dose to 450 units. 3 days later I had another blood test and went for scan to only find 2 mature enough eggs to think about collection and the other ovary had 3 well underdeveloped, and not worth considering. The FS said if the bloods came back at really high levels he would collect them. As expected though, my bloods had gone up slightly from base line but not enough to allow collection, so my cycle got cancelled. I was on Lucrin from CD5 and started the Gonal-F around a week later.

After the cycle was cancelled I decided to ovulate naturally but had another 2 days of unusual bleeding in the following weeks and continuing discomfort around one of my ovaries so am going to have it investigated next month with a lap. Provided everything is all clear, I'll be starting our next ICSI cycle straight after but starting straight up with 450units, which is the maximum dose our clinic will administer. I've heard in the past they used to allow 600 units but apparently there is sufficient research to state the ovaries don't really work any harder on anything past 450 units so its not worth it.

A friend had her second child with IVF and the first cycle she did was apparently very similar to mine. Her levels were ridiculously low and she wasn't responding to the drugs so the next cycle they started with high levels and got enough eggs to fertilise a few and the first fresh transfer resulted in her son.

So my fingers, legs, toes and hair fibres are all crossed that this next cycle produces some eggs for us to work with, and that your #4 cycle is a winner!
