Which term describes the ART cycle involving donor gametes or embryos not originating from the recipient?

• A. Embryo bank
• B. Embryo donation (for reproduction)
• C. Embryo transfer (ET)
• D. Ejaculation

Answer: (B)

When an ART cycle uses genetic material not from the recipient, you’re looking at donor-assisted reproduction. Specifically, embryo donation refers to using embryos created from donor gametes and donated for transfer to the recipient, or using donor embryos themselves for implantation. This captures the idea of a cycle powered by material that doesn’t originate from the recipient, enabling conception without the recipient’s own gametes contributing. The other options don’t describe this cycle. An embryo bank is a storage facility for embryos, not the cycle itself. Embryo transfer is the procedure of placing embryos into the uterus. Ejaculation is unrelated to the ART cycle terminology.
