Hi wayzee,
PCOS is a very individualistic disorder and does affect each woman with it very differently.
I have PCOS and was diagnosed with this on the basis of my highly irregular cycles and my bloodwork which showed the LH/FSH imbalance. I've also got the cystic follicles associated with this condition as well. Also the polycystic ovary can appear larger than a normal sized ovary (which is about the size of a walnut).
I would think you have more than 4 or 5 cystic follicles; the cystic follicles associated with PCOS are very small and it can take a skilled operator to spot them. Also such cystic follicles disappear - only to be replaced by further cystic follicles.
Some of these follicles contain hormones, others are dormant, some contain an egg.
Its a very thin line between polycystic ovaries and the syndrome but both have a commonality - the cystic follicles.
I was in a similar position to you at one time. I was offered the injectibles but opted for ovarian surgery due to funding issues with the trust (I would have to have waited six months before I could receive the injectible drugs). The diathermy surgery worked for me as I am now a parent as a direct result of such surgery.
You should be closely monitored whilst on IUI - what are your LH levels like now?.
Am glad you are managing to stay within the correct weight range for you height - this is important as weight gain can exacerbate symptoms.
I would keep the ovarian diathermy as an option open to you - would strongly suggest that you find out before you have this op (if you do end up having this surgery) how much experience the surgeon has had with this procedure and what his success rate has been.
I would also have a long chat with the cons about how he feels about you doing IUI and how many attempts he feels you need.
How often do you see the hospital team - at the very least you should be seen at least once every month by them and see the same people each visit (seeing different people each time is not helpful in terms of continuity of care).
Wishing you the very best of luck. As mentioned Verity's website is very good and would recommend that particular site to anyone with PCO/PCOS.
