What is the term for an ART cycle that was started with ovarian stimulation but did not proceed to follicular aspiration or embryo transfer?

• A. Blastocoele
• B. Blastocyst
• C. Blastomere
• D. Canceled ART cycle

Answer: (D)

In ART, cycle status terminology is about what happens after stimulation. When ovarian stimulation is started but the cycle stops before any follicular aspiration (egg retrieval) or embryo transfer, that cycle is labeled a canceled ART cycle. This designation specifically indicates that stimulation occurred, but the intended procedures did not proceed. It’s different from embryo-stage terms—blastocyst, blastomere, and blastocoele describe embryos at various development stages, not the status of the cycle itself. Cancellations can happen for clinical or safety reasons, such as poor ovarian response or risk concerns, or other technical issues that prevent retrieval or transfer from taking place.
