Endometrial receptivity testing can help provide new information about the uterus

Some fertility doctors may recommend endometrial receptivity testing to patients. This testing, in combination with a mock cycle and regular blood and ultrasound cycle monitoring, can provide valuable information about a woman’s uterine lining (endometrium).

The uterine lining is critical for supporting a pregnancy. During a woman’s menstrual cycle, this lining will thicken and be ready for an embryo to attach. This happens around cycle days 19-21 for most women with a normal cycle.

Why is endometrial receptivity important?

During an IVF cycle, our Las Vegas fertility doctors prescribe hormone medications to mimic the changes that happen in the uterus during natural conception. While these techniques prepare the uterus for most women, some patients may benefit from endometrial receptivity testing. This testing may assist in ensuring that a woman’s uterus is ready for an embryo to implant after an embryo transfer.

How does endometrial receptivity testing work?

For endometrial receptivity testing, a fertility doctor will prepare the patient’s uterus as if they will perform an embryo transfer, commonly known as a “mock transfer” or “mock cycle”. On the day when the transfer would occur, the doctor will perform an in-office uterine biopsy instead.

It takes about two weeks for the test results to come back. These results indicate whether the uterus was receptive during the mock cycle. If the uterus was not receptive, the doctor will make changes to make it more receptive to the actual embryo transfer in the future.

Who would benefit from endometrial receptivity testing?

Not every patient will need to undergo this type of testing. However, fertility doctors may recommend it for patients in certain situations.

  • Patients with repeated IVF failure. If a woman undergoes multiple IVF embryo transfers without successful implantation, our doctors may recommend this testing.
  • Patients who want to maximize their chance of success. Even patients who have not had an embryo transfer may consider this testing. For example, a patient who has only one or two high-quality embryos may undergo this testing to increase the chance of success with each transfer.

Our team recommends speaking with your doctor to determine whether endometrial receptivity testing is right for you and your family-building goals. If you have any questions about this or any other testing, contact us to schedule an appointment with our Las Vegas fertility doctors.
