IUI is similar to ivf in the early bits - still have ovulation induction, but instead of aiming for heaps of eggs for EPU, they aim for only a couple. instead of the eggs being collected and fertilised in the lab, ovulation is triggered, and then hubby's swimmers are inseminated into my uterus, so that they get to the right place right time.

my first two cycles used synarel but my body refused to wake up with the puregon, so the other 6 stim cycles have been without synarel at all. i've been lucky and only managed a couple of mild doses of OHSS that have mostly resolved themselves (although at the moment, my right ovary is something in the vacinity of 40 times larger than the left due to the stim drugs!)
