Previous studies have demonstrated hysterosalpingography (HSG) in general, and specifically with an oil-soluble contrast medium, directly increases pregnancy rates. Decision modelling was performed to compare fertility management using three HSG diagnostic strategies: (i) water-soluble contrast medium (WSCM)-HSG; (ii) Lipiodol® Ultra Fluid (LUF)-HSG; and (iii) No HSG, for women aged ≤39 years with unexplained infertility. Four reimbursement scenarios were modelled to reflect the various funding arrangements across the regions of the United Kingdom. Compared with WSCM-HSG, the live birth rates after 24 months increased by 3.4% with LUF-HSG and decreased by 2.7% with no HSG. From a patient perspective, fertility management with LUF-HSG is the most cost-effective strategy with cost-savings ranging from £299 to £857 per patient depending on the funding arrangement for IVF. From an NHS perspective, fertility management with LUF-HSG is cost-effective when 2 or more IVF cycles are NHS-funded. If none of the IVF cycles are NHS-funded, fertility management with LUF-HSG can be considered cost-effective if society is willing to pay £8,353 for an additional live birth. The findings from this analysis suggest that fertility management with WSCM-HSG is cost-effective compared to no HSG and LUF-HSG is the most cost-effective with increased live birth rates after 24 months.
