Eligibility
Key inclusion criteria

Minimum age
18 Years
Maximum age
No limit
Sex
Females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Have had any disruptive instrumentation within the uterine cavity (e.g. hysteroscopy, hysterosalpingogram, laparoscopy, surgically managed miscarriage or endometrial biopsy) within three months prior to day one of the planned embryo transfer cycle, or planning to undergo a procedure involving disruptive instrumentation at any stage during the study.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
To ensure allocation concealment, randomisation of eligible individuals will be performed by an online randomisation system built into the data collection software.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated block randomisation schedule, stratified for each fertility centre, will be created and protected by the database manager.
Masking / blinding
