Thanks everyone for your support and advice.

DP's low sperm count has been attributed to a problem with a hernia operation years ago, however, his count was not this low on our last cycle or on previous sperm tests (it was low, but not THIS low!)

We have decided that we need a severe lifestyle change before we commence our next cycle. Neither DP or I eat properly (he works nights and I get slack with cooking as it's just for me) and he has a very stressful job. He has given up alcohol but still drinks a lot of coke and to be honest we don't do much exercise.
We are going to sit down together on the weekend and work out a plan of attack. I'm going to do menu planning to ensure we eat better, he is giving up the soft drink, I am going to start acupuncture (and try and talk him in to doing it as well) and talk to the acupuncturist about herbs ect...RH76, I'll see if I can convince my DP like you did yours!
Melsta, might have to talk DP in to wearing boxers ALL the time aswell

We will go and see our current FS again and see what he says. If we are still not happy with him we will go to someone else.

We did our 2 stim cycles back to back, so I think we might have a break for 2-3 months to get our lifestyle on track and give it a chance to increase the count! It's just so hard to wait that long at our age, feels like every week is going to make our chances even lower!

I know we've only done 2 cycles and so many have done much more. I feel guilty complaining about it. I think this week was just such a shock to have zero fertilise, but maybe it's given us a kick up the *** to get healthier
We want to do everything we can before we have to look in to other options.

I wish everyone all the best.
Lissie good luck with your 4 little embies.
Tigerlinda, sending you lots of and best of luck on your next cycle.
