Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Women of reproductive age (<50 years) and who have a regular cycle that suggests ovulation, who are due to undergo hysterectomy for benign gynaecologcical conditions, will be recruited into the study. Following ethical approval and in the context of fully informed and written consent, 45 women will be randomised to one of three groups (n = 15 per group) in one single block of n=45 in a parallel-group design.

In the follicular phase of the cycle prior to hysterectomy Group 1 will receive a Lipiodol hysterosalpingogram (HSG), Group 2 will receive a control water soluble contrast media HSG and Group 3 will receive no intervention.

The dose of administered Lipiodol will not exceed 10mL in each case for each patient, with the duration of administration being confined to time of HSG procedure only (once off use). The mode of administration is via instillation through the cervical canal into the cervix and follopian tubes via a hysterosalpingography (HSG) procedure.

The attending Radiologist/physician will determine the exact dose of administered Lipiodol at the time of a HSG procedure. The minimum dose of Lipiodol to be administered above 5mL (including dead-volume in catheter) and until Lipiodol spill through the fimbriae is visualised by attending specialist radiologist under flouroscopy. A participant’s HSG procedure can vary in length, depending on clinical conditions between patients, however is not expected to exceed 20 mins in duration. A specialist Radiologist will administer the HSG procedure. The mode of administration is via instillation through the cervical canal using either a) Leech Wilkinson Cannula, or b) Cook Ballloon HSG Catheter, or c) a Rocket HSG Catheter. The type of water soluble contrast media utilised will be either Telebrix Hystero or agitated saline (which ever method is preferred by the Radiologist and in accordance to local protocol for HSG). The water soluble contrast media will be administered as per the lipidol administration procedure, the minimum dose will be above 5mL.

All HSG procedures completed by the respective Radiologists in each center will follow a clearly stipulated protocol for HSG as described above. Any deviations will be recorded by the attending radiologist and reported immediately to the trial coordinator.

Can healthy volunteers participate?
Yes
Key exclusion criteria
Exclusion criteria are:
- Any fibroid larger than 10cm in maximum dimension; (this change was made after 2 participants were recruited and at the initial screening stages of the MoFEEL trial)
- Known Malignancy;
- Known carrier of organism(s) associated with sexually transmitted infection (STI);

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
45 women will be randomised to one of three groups (n = 15 per group) in one single block of n=45 in a parallel-group design.

Allocation concealment will involve contacting the holder of the allocation schedule who was "off-site" or at central administration site (the trial coordinator).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence generation will involve simple randomisation using a randomisation table from a statistic book.
Stratified allocation will be employed in this study, utilising factors that can be used for stratification include centre, age, gender or previous treatment.

Statistical methods / analysis
Fifteen per group is a typical number of participants in trials that might unearth important differences or non-significant trends in the key immune-biological variables under study. Certainly, this number of participants per group will be sufficient to give information about likely differences in magnitude between the different interventions and the variation of the chances for each variable within each group.

Summary
Brief summary
Lipiodol, an oil soluble contrast medium (OSCM) has a clear fertility enhancing effect, but its mechanism of action is uncertain. This trial seeks to determine the feasibility, from both the clinical perspective and the laboratory perspective, of changes brought about by lipiodol within the endometrium, the fallopian tubes and the peritoneal lining. Establishing the variables within these tissues that demonstrate the trends of effect of largest magnitude when women who have had a lipiodol hysterosalpingogram (HSG) are compared to women who have had an HSG with a water soluble contrast medium (WSCM), and when women who have had a lipiodol HSG are compared to women who have had no intervention, is likely to point towards candidate mechanisms. This pilot randomised controlled trial (RCT) will then inform the feasibility of testing such variables in a definitive RCT of women with infertility that could, in the future, assess whether such changes are associated with a successful fertility outcome. Future RCTs examining the fertility efficacy of lipiodol could then endeavour to link fertility efficacy to the candidate mechanism as part of the entire RCT or within a cohort of women who form part of the overall RCT group, but in whom the mechanisms of lipiodol are also sought.
