Scientific title	A multicentre randomised controlled study of the effects of outpatient hysteroscopy on the outcome of the subsequent in-vitro fertilisation (IVF) cycle after recurrent IVF failure
Study acronym	Trophy in IVF
Study hypothesis	A recent systematic review suggested the outcome of in-vitro fertilisation (IVF) treatment could be improved in patients who have experienced recurrent IVF failure if an outpatient hysteroscopy (OH) is performed prior to starting the new treatment cycle. The review recommended performing a randomised trial to settle this research question. Therefore, this trial proposes to test the hypothesis that performing an OH prior to starting an IVF cycle improves the live birth rate of the subsequent IVF cycle in women who have experienced 2 - 4 previous failed IVF cycles.
Ethics approval(s)	Not provided at time of registration
Condition	Recurrent in-vitro fertilisation (IVF) failure
Intervention	The trial participants are randomised to one of two regimens: 1. Out-patient hysteroscopy in the follicular phase (days 5 - 14) of the menstrual cycle where the IVF cycle is due to start, followed by standard IVF treatment (according to local standard IVF protocol with or without the use of intracytoplasmic sperm injection 2. Standard IVF treatment (as above) without a prior out-patient hysteroscopy
Intervention type	Procedure/Surgery
Primary outcome measure	Live birth event per cycle started, measured after 9 months of embryo transfer.
Secondary outcome measures	1. Embryo implantation rate 2. Pregnancy rate per IVF cycle started 3. Clinical pregnancy rate per IVF cycle started 4. Miscarriage rate per pregnancy achieved Measured 2 and 4 weeks after embryo transfer.
