Endometrial Curettage Before Embryo Transfer

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

Studies have shown that endometrial sampling in the month prior to embryo transfer may increase pregnancy rates. We wish to test this hypothesis by performing a hysteroscopy and curettage in the month proceeding embryo transfer during IVF, IVF/ICSI or Frozen/Thawed cycles.

Condition Intervention
Infertility Procedure: Hysteroscopy and Curettage

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Endometrial Hysteroscopy and Curettage Prior to Embryo Transfer

Further study details as provided by HaEmek Medical Center, Israel:

Primary Outcome Measures:
  • Implantation rate
  • Pregnancy rate
  • Endometrial receptivity

Estimated Enrollment: 90
Study Start Date: December 2005
Detailed Description:

It has been suggested that local injury to the endometrium doubles the rate of implantation and successful pregnancies in IVF patients.


  1. To determine whether performing curettage the month prior to embryo transfer (ET) increases the chance of embryo implantation.
  2. To study molecular attributes of the endometrium taken at curettage and to compare them to those cycles resulting in pregnancy and those which do not result in pregnancy.

Samples will be grown as primary culture in the research laboratory and possible molecular markers and attachment assays for endometrial receptivity will be studied.

Patient selection: Patients undergoing IVF or IVF-ICSI at Ha'Emek medical center/ IVF unit. Woman over 35 years of age will be excluded since implantation failure is more likely to be due to genetic, chromosomal or cytoplasmic aberrations in their oocytes.

Proposed protocol:

  1. Informed consent obtained from prospective candidates.
  2. Participants randomly divided to three groups

    1. Control group
    2. Hysteroscopy and curettage performed on days 15-17 of menstrual cycle
    3. Hysteroscopy and curettage performed on days 19-22 of menstrual cycle
  3. After the following menses an IVF, IVF-ICSI, or frozen embryo cycle is performed according to the unit's standard protocols.
  4. The primary end point of the study will be the implantation rate after ET and the expression of possible molecular markers for endometrial receptivity in the pregnant patients.
