Tubal patency was assessed twice. Initial assessment of tubal patency had been performed by hysterosalpingo-contrast sonography (HyCoSy) or hysterosalpingography (HSG) and had suggested bilateral occlusion in the DTB group (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200938) and bilateral patency in controls (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200938).
