Doc says sperm count is low on the first sample given so wants to repeat the test before referring hubby to a urologist. I've heard that samples vary a lot - is this true?... so there might actually be nothing wrong? My initial thoughts are that it's too soon to repeat the test as lifestyle factors need to be ruled out (eg. alcohol intake) before going to a urologist. Can anyone else share their experiences? We're also concerned about the cost as our insurance won't cover it.
