They told me at the hospital that you will never produce more follies than you are born with so if you only ever had say 5 then thats all you will ever have no matter how high the drugs are... i will bei interested to see how many i have this time. I did have 9 last time and two small ones that did not grow enough to produce any eggs. Maybe i only have 11? Jesus its worrying.
This is not quite true Sammy - either your hospital are misinformed, or you slightly mis-understood what you were told.
You are born with all the eggs you are ever going to have, follicles are different things - they are like doors for your eggs to leave your ovaries from. At the start of each cycle (whether on IVF or not) your ovaries are ready to develop a certain number of follicles, and this usually diminishes as your ovarian reserve diminishes - so as a teenager you might have 20-30+ potential follicles at the start of each month, and as you get older it gets less, so by the time you reach your mid 30s, at the start of each cycle you may only have 10 potential follicles a month (though if you have good reserves it could still be 20+). In none medicated cycles, very early on one follicle becomes dominant and grows and matures one egg, and all the other follicles just give up the race and those eggs just get absorbed by your body. So in an IVF cycle, the maximum number of follicles you will potentially grow during that cycle can be seen via an antral follicle scan (not all clinics do this, as seeing it can't change it, however, if there are a large number of antral follicles, then this should be taken into consideration with drug doses), and this will vary from month to month, but it's a downward trend.
This also explains why repeated IVF and other medicated cycles don't bring on the menopause any earlier than if you don't have treatment. Our FS explained it like a 100m sprint, in a regular race 10 athletes line up to start, but there is only one winner, but in an IVF cycle, there is a potential 10-way tie for first place, as all the athletes have taken performing enhancing drugs!
Ladies with PCOS are pretty much the same, but don't get an early dominant follicle, so often end up with many partially matured eggs, and so have trouble getting pregnant as they don't so often produce good mature eggs.
