They finally called me back!
It was very difficult to get out of him how long it took to be analysed but he eventually said that it would have been around 90 minutes!!!
I said everything I had read even from World Health Org states it should ideally be within 30 mins but an hour at the absolute latest as otherwise surely they start dying off but he said that was rubbish and when they collect a sample for ivf they take it in the morning and don't use it until the afternoon and they are still flying around.
He said samples do fluctuate over time and some days are better than others and have obviously caught DH on a bad day but that his last test was also slightly below the norm and so that's two tests now and indicates that motility would def be sub optimal. I wondered whether the low volume DH produced the first time affected motility on that occasion but I forgot to ask that.
I really don't know what to think now
