Sperm Analysis?!

Stephanie
... Has anyone had 2 miscarriages within a year and needed to do a sperm analysis? My doctor won't do one because he said "MC" is common, and males reproduce sperm every 72 days...
... My Hubs is 47, I'm 33. I just feel like we need one after a loss, but in between the 2 MC we had a baby at 20 weeks with birth defects that had to be terminated. :( I feel something is wrong. Not the ole, don't worry!
