Placement into the uterus of an embryo at any embryonic stage from day 1 to day 7 after IVF or ICSI. Embryos from day 1 to day 3 can also be transferred into the fallopian tube

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

Answer: (A)

Embryo transfer describes placing an embryo created by IVF or ICSI into the uterus, at various ages after fertilization—from day 1 up to day 7. Some protocols historically used tubal transfer, where embryos that are day 1–3 could be placed into the fallopian tube, but the common practice today is uterine transfer. This distinguishes it from embryo fragmentation (embryo cells breaking apart), embryo donation (giving embryos to others for reproduction), and ejaculation (a male process unrelated to embryo placement).
