Question #45561
The Question
During an Assisted Reproductive Technology (ART) procedure, an embryo at the 16-blastomere stage is transferred into the uterus of a female patient. Concurrently, a physiological defect causes the premature regression of her corpus luteum. Which of the following is the most likely outcome and its correct physiological basis?
Options
- A.
The embryo will successfully implant because Intra Uterine Transfer (IUT) structurally bypasses the requirement of the fallopian tube's secretory phase.
- B.
Implantation will fail because the abrupt decline in progesterone prevents the maintenance of the secretory endometrium, leading to its sloughing.
- C.
The procedure will fail because embryos with more than 8 blastomeres require Zygote Intrafallopian Transfer (ZIFT) for proper development.
- D.
The embryo will implant but fail to develop further due to the absence of estrogen from the degenerating Graafian follicle.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often compartmentalize ART techniques (structural placement based on blastomere count) and human reproduction (hormonal control).
The trap is assuming that advanced ART techniques (like IUT) guarantee success by bypassing natural anatomical barriers, forgetting that the fundamental biochemical environment (progesterone-primed endometrium) is an absolute prerequisite for implantation.
