hi bianeczka,

i just responded to you in the other thread, but thought i would let you know that i have read that co-enzyme Q10 (you can buy it from the pharmacy), is sposed to help with egg development. on the back of the pack it actually says it helps with sperm development too. i havent tried it myself, but im sure some other girls in here have who might be able to tell you their experiences with it.
also, a friend was telling me the other day about a treatment for poor fertalisation rates/embryo development, HA-ICSI or PICSI. from what i understood a solution is added to the sperm sample, and only the top sperm will bind to this solution. they then use these sperm for injecting in to the egg. monash ivf have a useful fact sheet on their site about it, i am not with that clinic but found the info useful. something i might look in to if i dont get a successful result soon.
the only other thing i have pressed my FS for in my quest to find a reason for my unexplained infertility is to have the blood clotting tests done. just a blood test, usually they take around 7-9 vials for testing. sometimes they dont request these tests unless you ask. i guess if you are 'normal' on paper, they dont like to order unecessary tests.
i am hearing you about everyone else getting pregnant - my sister, older than me, got pregnant her first month of trying. its hard, but you've got to keep trying.
im sure the other girls in here will have more ideas for you too, but i tend to think that sometimes it is just luck. we can do all we can to improve our chances, but we are just waiting for that one perfect embryo to decide it will stick around. i hope you get yours soon.

goodluck.
