What is an OAR?

450x336-sep0413

During your matching process with an egg donor you will be presented the results of her OAR, or Ovarian Assessment Report. This test presents a complete picture of what each donor’s egg production results may look like while on fertility treatments.

The test is compiled after a simple blood sample has been taken from your donor. It will check for multiple things including hormone levels that, when compared against her age, will provide an egg retrieval score- a grading of potential ovulatory egg supply.

In general, the blood sample will be collected during her menstrual period, most typically on day 2, 3, or 4. The accuracy of the test depends on testing when estrogen levels are at their lowest. This is typically within 96 hours of full menstrual flow starting. In some rare cases estrogen levels may still be too elevated for the test to be accurate. In these cases your donor may need to have the test completed a second time.

When the results come back they are graded and assigned a category. The results will be either below normal, normal, or above normal. These designations are generally assigned based on the number of average eggs that can be expected to be retrieved during a given cycle.

  • Below Normal- These donors are expected to have an average of 9 eggs or fewer available for retrieval during a cycle. These donors are generally not ideal for gay couples using two sperm contributors and are usually only considered appropriate for a one person contribution case.
  • Normal- Or “average” results are donors who produce around 13 eggs for retrieval.
  • Above Normal- These donors are also coded as “excellent” and generally have an average of 20 eggs retrieved during her process. These donors are considered the gold standard for two contributor cases.

Most often, if a potential donor receives a “Below Normal” result she will be excluded from progressing further into our program. Certain forms of birth control can have adverse effects on an OAR test. In rare cases women on these forms of birth control may be asked to discontinue use of this birth control method, wait two full menstrual cycles, and then complete the OAR again.
