In ART terminology, which term denotes the transfer of one or more embryos into the uterus or fallopian tube to achieve pregnancy?

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

Answer: (C)

Embryo transfer is the step in assisted reproductive technology where the embryo or embryos are placed into the uterus (or, in rare older techniques, into the fallopian tube) so that implantation and pregnancy can begin. After eggs are retrieved and fertilized in the lab, selected embryos are carefully loaded into a thin catheter and transferred through the cervix into the uterus, giving them the best chance to implant in the lining. This term specifically describes the act of moving the embryos into the reproductive tract to achieve pregnancy, which is why it’s the correct choice. The other options describe different concepts: embryo fragmentation refers to a condition where some cells in an embryo have broken apart, not a transfer action; embryo donation involves giving embryos to another person or couple, not placing them into the uterus for a specific pregnancy; ejaculation is a male reproductive process and not related to transferring embryos.
