A 34-year-old woman with unexplained infertility has undergone 3 cycles of IUI without success. She is now offered IVF. The main advantage of IVF over IUI in this indication is:
- A Higher per-cycle pregnancy rate and ability to assess fertilisation and embryo quality ✓
- B Lower cost per cycle
- C Avoidance of ovarian stimulation
- D Eliminates the need for tubal patency testing
Correct answer: A. Higher per-cycle pregnancy rate and ability to assess fertilisation and embryo quality
Explanation
IVF offers a significantly higher per-cycle pregnancy rate than IUI (approximately 30–40% vs 10–15% per cycle in women under 35) and allows direct assessment of fertilisation capacity, embryo quality, and the opportunity for preimplantation genetic testing. IVF requires ovarian stimulation and is far more expensive. Tubal patency must still be assessed before IUI, but IVF bypasses tubal function entirely.
