Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Local Endometrial Trauma (LET), a randomised timed Pipelle endometrial biopsy. This would be done in the mid-luteal phase in the month immediately preceding the IVF treatment.
Intervention code [1] 287938 0
Treatment: Surgery
Comparator / control treatment
A randomised timed placebo biopsy where the patient would have the insertion of the Pipelle device into the cervix but not into the uterine cavity and no vacuum being drawn, thereby avoiding endometrial trauma whilst giving the impression of a biopsy. This would be done in the mid-luteal phase in the month immediately preceding IVF treatment.
Control group
Placebo

Secondary outcome [1] 304599 0
The effect of the LET procedure on positive serum HCG pregnancy test two weeks after embryo transfer

Secondary outcome [2] 304704 0
Pregnancy outcome up to delivery. Seen by regular pregnancy monitoring such as ultrasound, blood pressure testing and urine testing.

Secondary outcome [3] 304705 0
Endometrial tissue collected during the LET will be analysed for markers of successful implantation such as activin A, activin B, follistatin and their receptors.

Summary
Brief summary
The objective of this study is to determine wether local endometrium trauma (LET), applied once during the mid-luteal phase of the cycle preceding in vitro fertilization (IVF) treatment, can improve the chance of pregnancy for women with recurrent implantation failure.

The primary aim of this study will be the prescence of fetal heart activity seen on transvaginal ultrasound approximately four weeks after embryo trasnfer.

The secondary outcome will be the effect of the LET procedure on positive pregnancy test two weeks after embryo transfer, ongoing pregnancy, pregnancy outcome and complications up to delivery. Endometrail tissue collected during the LET will be analysed for putative markers of successful implantation.
