A bit late to this thread, and I see you've already had lots of useful information, but just wanted to add in my two pence worth.
DH has morphology issues, with 0-1% normal results. We ended up seeing Dr Ramsay about this, to see if we could improve things.
He started by saying that morphology is the hardest of the parameters to improve, and lifestyle can have a small effect but there is no magic bullet for the vast majority of cases. DH did pay (a small fortune) to have a lot of additional tests including ones for infections, as there are occasionally patients who have infections causing the morphology issues, and these can be treated with antibiotics. All his tests came back clear, and at this point, he said that we have to accept it is never going to improve. He also tried all the 'heat avoidance' things like baggy pants, no laptop on the lap, and even giving up running because it made him really really hot and sweaty. None of it worked for us, but it is probably worth trying. Bear in mind any change needs to be kept up for 3 months as that's how long it takes for the sperm to be produced...
However, we did also do a DNA fragmentation test, which looks at whether each sperm has normal DNA. This is obviously essential for a pregnancy. Ours came back very good, and Dr Ramsay said we basically have a packaging issue. The contents are fine but the packaging is dented. This did mean that we could do ICSI without too much worry that we wouldn't create normal embryos, and have had above-average fertilisation rates with our cycles.
Some clinics have better track records with male factor issues than others, because a lot of it comes down to the embryologist's skill and ability when injecting the eggs with the sperm (this is what ICSI is, and what you'll pay the premium for on top of the IVF cycle fee...)
A blunt instrument for spotting good male-factor clinics is to look for the ones that offer 'top up' treatments such as IMSI (ICSI with an extra-strong microscope) and PICSI (ICSI where they select the sperm by watching which ones swim towards a spot on the petri dish which is coated with the same chemical that eggs release to guide the sperms towards it)
Dr Ramsay told us he rated The Lister, but he works there so obviously would say that! We have also had cycles at Create and Chelsea & Westminster (the latter being our NHS round) and had more or less the same fertilisation rates at all of them.
