HI Rubles
'Fraid I can't help with the blood test questions, but just wanted to sympathsise. If you've gone through all this before, it seems ridiculous. Also goes to show it really does depend on your GP - mine is more than happy to refer me, even though I've managed to have DD and obviously got pg again before the MC and I'm only 31 [but then it did take 2 years to have DD, and a further 9 mths for 2nd pg]. Because we had already managed to conceive twice, she said there was no point doing all the normal bloods and DH sperm test, so she would refer me straight off.
Not wanting to obviously question your DH's virility, but when my DH had a sperm test when we were undergoing preliminary tests prior to DD, his results came back as sluggish, with 50% swimming the wrong way! He was obviously gutted, but I have to admit it made me giggle just thinking about confused, tired worms . But with my irregular cycle and his retarded sperm, it's really quite a miracle we've managed to conceive twice already!
Anyway, for DH sperm test, he simply had to collect a bottle from our local GP surgery, do the deed and get it to our local fertility clinic within 30 minutes!! and before 10am. Keeping the sample at body temperature on the way (so he stuck it in a sock down his trousers!). So it was pretty straight-forward - although he absolutely hated doing it.
I suppose what I'm saying is, your GP should look at things further, as just because you have already conceived, doesn't mean that you should wait another year before getting help. I would try yet another opinion, if you get no further.
Take care
