My husband just got the results of his SA. He has a low count at 5.4. Has anyone had similar numbers? 
His motility was really good... I keep thinking 'it only takes 1 to get through...' But realistically I just want to know if it's possible naturally. 
I of course have been reading up on everything....
He was referred to a urologist... And I'm just going crazy in the meantime. 
Just a little more about me, 
I have 2 children with my ex. I have a regular cycle no issues that I know of with my fertility.
