Administration of additional 'rescue' hCG immediately after IUI appeared to intensify considerably the pregnancy rate in IUI cycles. With a strong confirmatory result, it might eventually lead to avoidance of expensive artificial reproductive techniques i.e. IVF or ICSI in selected couples undergoing infertility treatment. 'Rescue' hCG post-IUI in couple with repeated failed conventional IUI may be recommended as it appeared to be safe with minimal detrimental effect.
