Endometrial thickness and texture assessed via transvaginal ultrasound and MRI-measured junctional zone thickness can predict pregnancy success. Specific measurements indicate higher pregnancy rates and aid in diagnosing adenomyosis, a cause of IVF failure.

Area of Science:

  • Reproductive Endocrinology
  • Medical Imaging
  • Infertility Research

Context:

  • Transvaginal sonography is used to evaluate endometrial characteristics.
  • Adenomyosis is a recognized cause of recurrent implantation failure in in vitro fertilization (IVF).
  • Previous IVF attempts may not have fully explored all potential causes of implantation failure.

Purpose:

  • To determine the predictive value of endometrial thickness and texture for pregnancy.
  • To assess the utility of Magnetic Resonance (MR) imaging in diagnosing adenomyosis.
  • To establish MR imaging-based criteria for predicting implantation failure in IVF.

Summary:

  • Endometrial thickness less than 6 mm is associated with very low pregnancy rates.
  • Type C endometrium (multilayered, specific echogenic patterns) ≥ 6 mm thick shows good pregnancy rates per embryo transfer.

Related Experiment Videos

  • MR imaging accurately diagnoses adenomyosis, with junctional zone thickness (AJZ > 7 mm, MJZ > 10 mm) being a strong negative predictor of implantation failure (97%).

    • Impact:

    • Transvaginal sonography can guide fertility treatments by assessing endometrial receptivity.
    • MRI evaluation of junctional zone thickness is recommended for women with two consecutive IVF implantation failures.
    • This research advocates for routine MRI assessment of junctional zone thickness in specific patient populations to improve IVF outcomes.
