- Brief summaryIn the evaluation of female subfertility, hysterosalpingography (HSG) is an important examination because of its diagnostic value. The procedure delineates the uterine cavity contours and the rugation and the patency of the fallopian tubes. Since the introduction of HSG as a diagnostic test, various contrast media have been used, from water-soluble to oil-soluble, ionic to nonionic, and high osmolarity to low osmolarity.

A possible therapeutic effect of diagnostic tubal patency testing has been debated in the literature for more than 50 years.

There are some small studies that show that flushing with Oil-soluble contrast medium (OSCM) has a significant higher odds ratio of live birth compared to flushing with Water-soluble contrast medium (WSCM). But other small studies showed no significant different in odds ratio of pregnancy or live births after flushing during HSG examination with OSCM or WSCM.

The purpose of this multi centre, randomised controlled trial, is to determine whether at HSG the use of oil-based contrast media results in higher ongoing pregnancy and live birth rates compared to the use of water-based contrast media.
- Main changes (audit trail)7-feb-2017: Changes in primary and secondary outcome-EB

- Primary outcome:
“Ongoing pregnancy rates” changed in
“Ongoing pregnancy defined as registered heartbeat on ultrasound beyond 12 weeks of gestation within the first 6 months after randomisation.”

- Secondary outcome
“Live birth rates, miscariages, ectopic pregnancy and pain scores.” changed in:
“Clinical pregnancy, defined as an ultrasound visible gestational sac.”
“Miscarriage, defined as a spontaneous loss off pregnancy”
“Ectopic pregnancy, defined as an embryo implants outside the uterine cavity.”
“Pregnancy leading to live birth”
“Live birth, defined as the birth of at least one living child.”
“Pain scores after the procedure.”
“Cost calculations of OSCM / WSCM and assisted reproductive technology (ART) treatments.”
