Hi hun
Has hubby done 2 or even 3 samples hun before they diagnosed him, i only ask because my hubby SA was on the slow side but large volumes(lazy like him

), but we where told at my clinic they NEVER go by one sample, because the day that sample was done hubby could of been stressed, run down, ill anything, and they always do two samples to conclude a diagnosise hun, sometime even three if they are not sure....
Mayby if they only did one sample it would be worth doing another one to compare them, if not medical advances are AMAZING hun, and its not the end of the world, but a wee bump in the road to motherhood...
Its crazy we grow up being petrified of falling pregnant and when we "try" its VERY hard, anyway ALL the luck and positive vibes in the world, and keep us posted, and remember your hubby will be needing as much support through this as yourself, so give him a HUGE cuddle xxxxxx
