Sherrie, The probability that your sons are carriers is 50%. Those odds are not affected by whether or not your first husband was a carrier. The two possible sets of odds for any children you had by your first husband are: If your first husband is a carrier children's odds are: 25% Normal 50% carrier 25% CAH If your first husband is normal (doesn't have CAH and is not a carrier) children's odds are: 50% Normal 50% carrier The best thing is for your sons to be tested. Hope this helps, JoanJoanW
