Sperm donors - does blood type matter? MOT10 OR MOT20? Confused!

Hi ladies,

About to order some sperm - yikes.

Can anyone help me with the below? My clinic nor the sperm bank are being very helpful, hence why I need you lovely ladies!

1) Should I purchase MOT10 or MOT20?

2) Is MOT10 better quality sperm than MOT20, or just more volume of the same quality?

3) How many "straws" should I purchase (they are expensive)? Do you need one straw per cycle, or can I purchase a MOT20 straw and it lasts for many cycles?

4) Roughly, how many cycles would an MOT10 or MOT20 straw last for?

5) Does blood type matter? I read something about this, but not sure if there is any truth to it?

Thanks so much xx

Hi Anna

I’ve no idea what MOT10 or 20 are but I can answer the other questions.

Blood type doesn’t matter but depending on your clinic your CMV does. I had to have a test to see if I was CMV positive or negative before I ordered. If your blood type is CMV negative then you need a negative donor as your blood antibodies can react against the positive donor if you choose the wrong type.

I only purchased 1 straw at a time. This would work for one IUI or one round of IVF/ICSI.

Good luck and let me know if you have any more questions x

Hi I don’t know the answers to most of your question but I would say blood type does matter if you have negative blood and have anti D in your system maybe from a previous pregnancy or miscarriage. I’m sure if that’s the case your doctors would advise. I had anti d so needed a negative egg donor and luckily my hubby was negative so no probs xxx

Thanks so much! What is anti D? xx

Hi Anna. Doesn’t really matter. However, if you have a rhesus negative blood group, you will be offered an anti D injection to protect baby from developing an incomparable blog group - quite safe. Diane

Thanks so much Diane. I am B+ - does this mean I am not in the negative blood group and every blood type is ok?

Hi. Yes, just appplies to you being negative. Diane

Hello! I'm in the same boat.

I am A negative, and dont know CMV status (but I'm told it doesnt matter).

Wondering if I should only pick a negative RH donor sperm, but there are already so few donors. I also wonder if picking an A+ if I'm giving the kid a chance to have a more common blood group.

Its overwhelming I know I can have an injection at 28 weeks, but still wondering if I'm stacking the odds against my baby. I only plan 1, but you never know, and I think it can impact 2nd pregnancies..
