1% normal would be the morphology. This is how the sperm is shaped. My specialist described it to us like this "its a bit like a beauty contest, the egg is very picky and will only allow 'good looking' sperm in".
If the motility is 50% then it is at the low end of the 'normal' scale.
I hope I don't scare you but I would DEFINITELY be seeing a specialist. If you don't feel you're ready for that then there is a suppliment out called 'menevit' which is full of important sperm repairing anti oxidants and it has had a lot of success.
A specialist (eg at an IVF clinic) would organise another sperm analysis where they do the usual sperm count, motility, morphology etc but they also wash and spin the sperm and check for DNA fragmentation (damage).
If DH has only had 1 test, then be sure to get at least 1 more test done. How long did he abstain for? My specialist (who also specialises in male factor infertility) said to abstain no longer than 3 days, any longer and it can give an inaccurate reading.
GP's honestly don't know much, and no, i'm not a doctor, but with all DH's sperm probs I have learnt A LOT about sperm and what is and isn't normal and low morphology isn't normal. Its not normal for it to be really high, but they do like it to be a minimum of 5%.
Just to give you an idea, my DH had 3 regular lab tests and 2 big ones with our IVF clinic.
His latest one came back as:
Count - can't remember but it was below normal
Motility - 35% (it has been as low as 1% before)
Morphology - 1%
DNA Fragmentation (damage) - 19% (which is quite high as any higher than 29% they cannot work with).
With those results our only option is IVF ICSI. Unfortunately there is nothing (except for life style changes and even then its only a 'maybe') available for men in the form of treatment.
If you have any questions ask away, and as I said I hope I didn't scare you! Was your DH's count good? If so, then morphology is your only major problem, motility a bit low but wouldn't make it impossible to conceive naturally.
