Having PCOS complicates everything. For me, the dosage needs to be high enough to get a response, but there's a VERY fine line between no response and too much response with me. It's always easier to stimulate the ovaries of woman without PCOS as things can be a little more predictable. Some clinics take the cautious approach while others... well... they tend to go to egg collection and freeze all rather than cancel, but this can leave you very sick - I was in hospital for a week after my second EPU.

IUI is intra-uterine insemination.
