Male donor is Kell positive. What are the associated risks to the surrogate?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My husband and I will be using a surrogate to have kids. My husband is Kell-positive (heterozygous). What are the risks to this that the surrogate would need to be aware of?

Kindly help.

Answered by Dr. Kamal Kant Sahu

Hello,

Welcome to icliniq.com.

A few points include:

1. As per medical facts, the first pregnancy remains silent. In your case, the surrogate is Kell negative, which means her body is still not exposed to Kell antigens, which is good, so this pregnancy will be safe.

2. As the husband is heterozygous, it means he has only a 50% chance of having a baby who is Kell positive. In the other 50%, there is no risk of complications.

So, theoretically, this pregnancy should go silent without complications. But then the surrogate will be exposed to the Kell antigen from your husband; she should be aware of this risk, which can create trouble in future pregnancies if the male is Kell positive.

I hope this helps.
