Oil-Based or Water-Based Contrast for Hysterosalpingography in Infertile Women.

Abstract Pregnancy rates among infertile women have been reported to increase after hysterosalpingography, but it is unclear whether the type of contrast medium used (oil-based or water-soluble contrast) influences this potential therapeutic effect.

AB  - BACKGROUND: Pregnancy rates among infertile women have been reported to increase 
      after hysterosalpingography, but it is unclear whether the type of contrast
      medium used (oil-based or water-soluble contrast) influences this potential
      therapeutic effect. METHODS: We performed a multicenter, randomized trial in 27
      hospitals in the Netherlands in which infertile women who were undergoing
      hysterosalpingography were randomly assigned to undergo this procedure with the
      use of oil-based or water-based contrast. Subsequently, couples received
      expectant management or the women underwent intrauterine insemination. The
      primary outcome was ongoing pregnancy within 6 months after randomization.
      Outcomes were analyzed according to the intention-to-treat principle. RESULTS: A 
      total of 1119 women were randomly assigned to hysterosalpingography with oil
      contrast (557 women) or water contrast (562 women). A total of 220 of 554 women
      in the oil group (39.7%) and 161 of 554 women in the water group (29.1%) had an
      ongoing pregnancy (rate ratio, 1.37; 95% confidence interval [CI], 1.16 to 1.61; 
      P<0.001), and 214 of 552 women in the oil group (38.8%) and 155 of 552 women in
      the water group (28.1%) had live births (rate ratio, 1.38; 95% CI, 1.17 to 1.64; 
      P<0.001). Rates of adverse events were low and similar in the two groups.
      CONCLUSIONS: Rates of ongoing pregnancy and live births were higher among women
      who underwent hysterosalpingography with oil contrast than among women who
      underwent this procedure with water contrast. (Netherlands Trial Register number,
      NTR3270 .).
