Since there is no volunteer andrologist I figured I would ask this here in case anyone can offer any information.
It is my understanding that the normal total motility standard for ejaculated samples is over 40%.
I have read some studies that show that it is normal for total motility to decrease after freezing, however some of these studies are older and may now be outdated.
If it is normal for total motility to drop off after freezing, is there a corresponding "normal standard" for motility post thaw?
I ask because DH recently had a sample frozen which had a total motility of 47% before freezing (in the normal range) and the total motility post thaw was 23%. We were told that this means that DH's sample is of poor quality because the total motility post thaw has to be over 40% to be considered normal.
If anyone has any information it would be appreciated!
