Within the artificial insemination sector, the dominant Market segment in South Korea is Intrauterine Insemination (IUI), accounting for the largest volume of procedures among all Assisted Reproductive Technology (ART) cycles in 2022. IUI is favored as the initial, less invasive, and more cost-effective treatment for couples with unexplained infertility, mild male factor infertility, or those using donor sperm. Its dominance at the volume level is critical because it acts as the primary gateway for couples entering the formal fertility treatment process. The procedural volume for IUI cycles significantly outstrips more complex methods, even though the total revenue generated by IVF may be higher due to the latter’s higher price point. This segmentation is heavily influenced by the structured approach to fertility care, where medical guidelines often mandate trying multiple IUI cycles before progressing to IVF, especially in subsidized or publicly funded systems. The government's recent expansion of the total number of subsidized cycles available to couples—up to 25 cumulative treatments for IVF and IUI combined—ensures that the IUI segment will retain its high procedural volume status for the foreseeable future.

The segmentation analysis also extends to the products and components used in the procedure. This includes consumables like IUI catheters, which must meet stringent quality standards and are seeing increasing demand, as well as specialized media for sperm washing and preparation, which are vital for optimizing success rates. The market for donor services also forms a distinct segment, though cultural and legal constraints in South Korea mean that services involving donor gametes, while available, operate under a different regulatory and ethical framework than non-donor cycles. As treatment protocols become more personalized, sub-segments based on the cause of infertility, such as mild endometriosis or ovulatory dysfunction, will also grow in importance, influencing the specific drug and device combinations used alongside the core IUI procedure. Accurate measurement of the IUI South Korea Artificial Insemination Market segment is therefore essential for strategic resource allocation across the entire reproductive healthcare supply chain.
