In September, DH had his sperm tested and his morphology was low at 2% (normal should be more than 4%). Well, four months on and he has been re-tested, and it has gone from 2% to 6%.
His sperm count has also gone from 61 million to 99 million (normal is over 15 million). So, not only has the percentage of his normal shaped sperm tripled, but there's also a lot more of them!
I have seen lots of threads from other posters whose DHs have low morphology so I thought I'd share the changes we made. Essentially, it's a lot of daily supplements! Here goes:
The latter two were started due to me researching threads on here about anti-oxidants having a good effect on sperm!
In terms of lifestyle changes, the only one he's really made is not putting his laptop directly on his lap when working, he will put it on a cushion instead. He is a couple of stones overweight but we have had a lot going on in the past few months (including a CP 
) and we haven't really been in the headspace to exercise. However we both had it as a new year's resolution so have been trying to do some over the past couple of weeks, but I'm pretty sure that won't have had an effect on things.
I have worked out that whereas in September, one, er, session shall we call it, would have produced 2.68 million progressive, normal shaped sperm, this is now up to 12.92 million sperm. I just wish one of them would find its way to my eggs haha!
Best of luck everyone, I hope this is of use to someone!!
