NCT01882842

Brief Summary

This study aims to see if taking a small sample from the lining of the womb (the 'scratch') before starting in vitro fertilization (IVF) treatment can influence the chance of getting pregnant and having a healthy, term baby. This study also aims to explore why an embryo is not accepted or indeed rejected by the lining of the womb. This will be analysed by carefully looking at the sample taken from the lining of the womb under the microscope and analysing the levels of natural killer (NK) cells. These cells are thought to regulate the implantation process and to be altered in some women with infertility and miscarriage.

Outcome Measures

Primary Outcomes (1)

  • A difference in the term (37 completed weeks of gestation), singleton live birth rate in women undergoing IVF/ICSI treatment following endometrial biopsy versus control subjects.

    Approximately 9 months after completion of the last procedure of the last study participant.

Secondary Outcomes (7)

  • A difference in the live birth rate (birth of a live baby after 24th week of gestation and before 37th completed weeks) in women undergoing IVF/ICSI treatment following endometrial biopsy versus control subjects.

    Approximately 9 months after completion of the last procedure of the last study participant.

  • A difference in the multiple pregnancy rate in women undergoing IVF/ICSI treatment following endometrial biopsy versus control subjects.

    Approximately 9 months after completion of the last procedure of the last study participant.

  • A difference in the implantation rate in women undergoing IVF/ICSI treatment following endometrial biopsy versus control subjects.

    Approximately 9 months after completion of the last procedure of the last study participant.

  • A difference in the biochemical pregnancy rate in women undergoing IVF/ICSI treatment following endometrial biopsy versus control subjects.

    Approximately 9 months after completion of the last procedure of the last study participant.

  • A difference in the clinical pregnancy rate in women undergoing IVF/ICSI treatment following endometrial biopsy versus control subjects.

    Approximately 9 months after completion of the last procedure of the last study participant.

  • +2 more secondary outcomes

Other Outcomes (1)

  • Sonographic markers of endometrial receptivity

    Approximately 2 years

Study Arms (2)

Endometrial biopsy arm

EXPERIMENTAL

Participants randomised to this arm arm will undergo an endometrial biopsy procedure using Pipelle endometrial sampler (Pipelle de Cornier, Laboratoire CCD, Paris, France) or Wallace/ Wallach endometrial sampler as an alternative device on cycle day LH+7 to LH+9 of the cycle directly preceding commencement of down-regulation prior to IVF or ICSI treatment. A transvaginal ultrasound scan will be performed prior to the biopsy.

Procedure: Endometrial biopsyDevice: Transvaginal ultrasound

Control group

NO INTERVENTION

Participants randomised to control group will undergo a transvaginal ultrasound scan on day LH+7 to LH+9 of the cycle directly preceding commencement of IVF/ICSI treatment.

Interventions

Endometrial biopsy will be performed in the study group and timed according to a positive urinary LH (ovulation) kit at LH+7 to +9 days.

Also known as: Pipelle de Cornier (CCD, Paris).
Endometrial biopsy arm

A detailed assessment of the endometrium will be performed including two- and three- dimensional ultrasound, as well as power Doppler acquisitions.

Also known as: GE Voluson E8 (Austria)
