Question #45576
The Question
A 30-year-old female with a history of chronic, untreated Neisseria gonorrhoeae infection presents with secondary infertility due to severe Pelvic Inflammatory Disease (PID). The physician recommends in vitro fertilization (IVF). Which of the following embryo transfer strategies is strictly contraindicated for this patient, and what is the precise biological rationale?
Options
- A.
IUT; because an embryo with more than 8 blastomeres requires functional ciliated epithelium in the fallopian tubes for successful implantation.
- B.
ZIFT; because the transfer of a zygote or early embryo (up to 8 blastomeres) into the fallopian tube risks ectopic pregnancy or implantation failure due to tubal occlusion.
- C.
GIFT; because the transfer of a donor ovum and sperm into the uterus will fail due to PID-induced endometrial scarring.
- D.
ZIFT; because the transfer of an embryo with more than 8 blastomeres into the fallopian tube cannot bypass the tubal blockage.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often memorize ART acronyms without visualizing the anatomical locations and physiological prerequisites.
The core trap requires linking the pathological consequence of an STI (tubal blockage via PID) to the mechanical requirements of ART.
Furthermore, Option D exploits a classic NCERT quantitative nuance trap by mixing up the blastomere count for ZIFT (up to 8) and IUT (more than 8).
