My husband and i have been trying for 18 months. I have had blood tests - all fine, im ovulating, periods are regular, my overies have been checked all ok. My husband did a seman sample and he has a low sperm count so the doctor has suggested IUI. My husband has to do another seman sample this week to see if any of his sperms are good ones. My question is if there are (hopefully!) then what do they do with that sperm? Do they freeze them until im ready to ovulate? If its not succesful how many trys do you get? My huband is trying to loose weight, does this really make a difference to his sperm count or the quality?
