SA Viscosity Question

[Popsiclewopsicle]

Hiya. Dh has a SA done recently and all the results are fine...
Total motility - 58% (progressive were 56%, non progressive 2%, and immotile 42%)
Count - 48 million
Ph- 8.2
Morphology- 7%

But they’ve said the viscosity was too high at 3.06ml and a high viscosity can interfere with sperm determination of motility and concentration.
But is that the case then if everything else came back above the lower reference limits? And anybody got any tips on how to thin it out?!
