Only because the seamen contains no sperm. The germline is unaffected by marrow transplants

  Right, his red blood cells have donor DNA, and when they die they leave DNA fragments that eventually get excreted in seminal fluid. This isn't some weird testicle transplant situation. It's closer to other stories of micro or "trace" contamination.

  whose DNA will the kid have?

    Semen without sperm will not produce a child, I’d imagine.

    The sperm is what makes the child (along with the egg, obviously), which is what is meant by "the germline is unaffected". Thus, the child will have the DNA of the mother and the father. The donor doesn't really factor in to that story. Given the generally separate nature of testicles, it would be really surprising if that wasn't the case.
