Dr. Mary Wingfield:

That particular phrase can apply to sperm, eggs and embryo. The phrase of itself is okay but it is used throughout the document and is confusing because there are sections in the document that refer to a child being conceived using "human reproductive material" from a man only. That cannot happen because a sperm and egg are needed. It means the man who is intending to be the parent. The way it is written is very confusing. That situation refers to a couple in which the man is using his sperm and donated eggs. It would be much simpler to say sperm and eggs rather than "human reproductive material" from a man only.
