BACKGROUND: A multicentre randomized controlled trial with or without hysterosalpingography (HSG) was conducted to assess the usefulness of HSG as a routine investigation in the fertility workup prior to laparoscopy and dye. METHODS:From 1 April 1997 to 1 April 2002, subfertile women were allocated by a computer-based 1 : 1 ratio randomization procedure, either for an HSG followed by laparoscopy and dye (the intervention group) of for laparoscopy and dye only (the control group) as a part of their fertility workup. Cumulative pregnancy rate (CPR) within 18 months after randomization was the primary outcome of interest. RESULTS:344 women were randomized to the intervention group (n = 169) and the control group (n = 175). There was no significant difference in CPR at 18 months in the intervention group (49.1%) [95% confidence interval (CI) 41.6 to 56.6] and the control group (50.3%) (95% CI 42.8 to 57.8), a difference of -1.2% (95% CI -11.8% to 9.5%). CONCLUSION: The routine use of HSG at an early stage in the fertility workup prior to laparoscopy and dye does not influence CPR, compared with the routine use of laparoscopy and dye without HSG.
