Question #45547
The Question
A 30-year-old female patient seeks Assisted Reproductive Technology (ART) to conceive. Clinical evaluation reveals she cannot produce functional ova, though her uterine endometrium is highly receptive. Additionally, hysterosalpingography indicates severe bilateral oviductal adhesions (blocked fallopian tubes). Based on NCERT principles, which of the following ART strategies is scientifically justified for this patient?
Options
- A.
GIFT using a donor ovum, as it provides the missing gamete while utilizing her natural capacity for in vivo fertilization.
- B.
ZIFT using a donor ovum, because transferring a pre-formed zygote bypasses the need for oviductal fertilization.
- C.
IVF using a donor ovum followed by IUT, as it completely bypasses the structural requirement of patent fallopian tubes.
- D.
ICSI followed by GIFT, to ensure fertilization is guaranteed before the gametes undergo tubal transport.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often blindly map 'cannot produce ovum' directly to 'GIFT' based on a memorized NCERT line.
The trap lies in failing to synthesize the structural prerequisite for GIFT and ZIFT: at least one patent (open) fallopian tube is mandatory for fertilization and/or subsequent transport to the uterus.
Blocked tubes strictly necessitate IUT.
