An ART cycle consisting of the transfer of an embryo to the uterus or fallopian tube of a female recipient, resulting from gametes that did not originate from the female recipient or from her male partner, if present?

An ART cycle consisting of the transfer of an embryo to the uterus or fallopian tube of a female recipient, resulting from gametes that did not originate from the female recipient or from her male partner, if present?

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

Answer: (A)

Embryo donation involves using embryos created from donor gametes and transferring them into a recipient. In this scenario, the embryo placed into the recipient comes from gametes that did not originate with the female recipient (or her partner, if present), so the cycle is defined by the donor origin of the embryo. The act of transferring the embryo to the uterus or fallopian tube is the embryo transfer procedure, but the key factor here is that the embryos are donated from outside the couple, which makes it embryo donation. The other options describe different concepts: embryo transfer is the placement step, embryo bank is storage, and embryo fragmentation refers to a cellular/embryo quality issue rather than donor origin.
