Hey there, I have a mate who is in a very similar prediciment! when they got married five years ago, the found out her husband would never be able to father kids! So they remained positive, and decided to find a sperm donor.
So march 2003, she found out she was pregnant! and both were over the moon, and she gave birth to a most beautiful little boy in October that year. (NOW DONT pass this bit on to her) unfortunately after a rather great pregnancy, this baby died twelve hours later, thru complications from birth, so in retrospect, this couldve happened to anyones baby, and was in no way couteractive of the conception.
That pregnancy took 3 attempts, which is pretty good, and she is now pregnant with her second child (12 weeks) and this time it only took one attempt. She had to take hormone pills for both attempts, but her and her husband were able to choose their sperm donor, and luckily have been able to use him for this pregnancy, so all her kids when she has more, haahah will have full blooded connections.
Hope all goes well with your mate, they have to remain positive, and if they really want this, it is within their reach, but the longer they leave it, the harder it could get.!!!
Hope this helps Love Kel and mckenzie xoxoxox
