I realize this is probably an ignorant question - and is certainly one I should have asked in the lengthy preparatory process that my clinic requires! Our donor database lists the blood type of each donor, so I assume that means I should be concerned about or otherwise pay attention to it? I'm ashamed to say that I have no earthly idea what my own blood type is - and I assume that matters too? Ack? Advice and guidance appreciated! Thx!

I didn't know my blood type either - some intended parents select a donor with the same blood type so that their child will have the same blood type that they would have had without a donor - I'm not sure exactly why, but I guess it makes it easier not to tell your child or their medical providers about using DE. Blood type wasn't a factor in our donor choice - we will be open with our child. Good luck with your donor selection - I read your other thread and sounds like you and your husband made a great choice!

then it's advisable to choose a donor that has a blood type that's compatible to what you and your DH have, but it is in no way necessary. Your chances are the same regardless. Good luck to you!

Do a search and you should find charts online to show what blood types can result from parents with specified blood types. For example, I'm O-, so I'm pretty much a blank slate -- I could choose a donor with my blood type (which make for a very limited donor pool) or either allele of my partner's blood type.

This actually turned out to have been an issue for me inasmuch as I gave the Czech clinic where I cycled my blood type, but we were using DS and my partner actually did not know his blood type (and I planned to tell, so I didn't care). But when I didn't specify a blood type for my SD, the clinic unilaterally decided to choose O- donors (remember, I'm a blank slate, so ED had to be O-, too) as I didn't state that it didn't matter, and only about 8% of Caucasians are O-, so that greatly limited the donor pool and I got a BFN.

When I realized what happened, I was so paranoid that they might overlook or ignore a request that blood type didn't matter that I went to Wikipedia and looked up the largest blood type group for central Europe and gave that as DH's blood type for my second cycle. BFP.

All-in-all, even though we're pretty much tell to the world due to my age, I wish we had known DH's blood type -- he has had something like five major surgeries; how the heck did he not know? I've donated gallons of blood, so it's hard to imagine not knowing.

and the only other thing my OB mentioned was that where your blood type differs from your donor's, there can sometimes be an issue with different blood types crossing the placenta (the antibodies of one type may attack the other? sorry to be so vague - i need to look into this furhter). that being, she said this is rare and treatable but something they need to watch for where the blood types differ. I'm in this boat. SMRC

Equally spread across all of the blood groups, 15% of each blood group is Rh negative. 85% are Rh positive. If the pregnant mom is Rh negative and the baby is Rh positive, the mom has to have a couple of shots so she can't build up immunities to future RH positvie babies. The shots are no big deal at all and every mom is routinely checked nowadays. I wouldn't refuse a donor just because she's positive unless you and your husband both are negative and you're no-tell. Best of luck!

My donor happened to have my blood type, but I was fine with finding a donor that would result with a child with a blood type that is possible from my blood type and that of my (now X) husband. We are no tell so I didn't want this giving it away unless I wanted to disclose.

Those are in the 'tell camp' aren't as concerned about it.

As I am far from science minded & am confused. I may have misunderstood but if I am O+ and DH is AB neg and hopeful donor is A neg will that mean there will be a problem?

acc'd to this, there could be a child who has AB type blood from donor + DH blood types, and AB result is not a possibility with your blood type.
