Does a reproductive medicine perform endometrial receptivity testing?

Endometrial receptivity testing, sometimes called an ERA test or implantation window test, examines a small sample of the uterine lining. A reproductive medicine doctor decides whether the test could add useful information, plans the cycle timing, and arranges laboratory analysis. The sample is usually collected with a catheter passed through the cervix, and some people experience cramping or light bleeding afterward.

The result may be discussed alongside your medical history, embryo details, uterine assessment, and previous treatment. It does not replace an individual review of other factors that can affect embryo implantation. Your clinician should explain what the result can and cannot change before you consent.

Ask the clinic which cycle medicines and appointments are needed, how the biopsy date is selected, and when results are expected. Tell the team about pregnancy possibility, pelvic infection symptoms, allergies, medicines, or a condition affecting bleeding. Arrange a plan for pain relief that fits your health history, and keep the written instructions available on the day.

Contact your care team after the biopsy if pain is severe or worsening, bleeding is heavy, fever develops, or discharge has an unusual smell. Seek urgent medical help for fainting, severe weakness, or sudden severe abdominal pain. Report symptoms promptly so the team can assess infection, bleeding, or another cause rather than assuming they are expected effects.

Consider asking: Why might this test help in my situation? How is the biopsy timed? What discomfort and aftercare should I expect? How could the result affect embryo-transfer timing or medicines? What other explanations will be considered if the result does not change the plan?
