Stimulated Intrauterine Insemination: Efficient, cost-effective, safe?

Abstract

A retrospective report of pregnancy and birth rates achieved in 1010 cycles of stimulated intrauterine insemination (SIUI). Over the years there has been an increasing emphasis on safety, particularly towards reducing the number of high order multiple pregnancies. SIUI is a complex form of assisted conception and requires a high level of clinical judgement to maintain an optimal balance between maximising pregnancy and birth rates and minimising complications, of which the most serious is multiple pregnancy. Extrapolating from these results, it is concluded that a well managed SIUI programme that selects patients appropriately, monitors them intensively and has in place effective strategies to manage over-responders safely, should be able to deliver at least a 15% live birth rate per cycle started with only a 5% cycle cancellation rate. Although SIUI birth rates are lower than IVF rates, the much lower cost of SIUI means that this treatment can be more cost-effective than IVF. However SIUI remains more risky than IVF and, despite careful management, high order multiple pregnancy rates will occasionally occur. It is estimated that the rate of unavoidable high order multiple pregnancies (triplets and above) is 4 per 1000 cycles started.
