GERT (GENNET Endometrial Receptivity Test)
A specialized genetic test that evaluates the readiness of the uterine lining to receive an embryo.
Endometrium (uterine lining)
The inner lining of the uterus that changes throughout the cycle and enables embryo implantation.
Endometrial receptivity window (implantation window)
A short period when the uterine lining is optimally prepared to accept an embryo.
Embryo implantation
The process by which an embryo attaches to and embeds in the uterine lining.
Embryo transfer
The placement of an embryo into the uterus during fertility treatment (e.g., IVF).
Biochemical pregnancy
A very early pregnancy detected only by laboratory tests (e.g., blood tests) that does not progress further.
Implantation failure
A condition in which the embryo repeatedly fails to implant in the uterus.
Endometrial biopsy
A procedure in which a small sample of the uterine lining is collected for examination.
Cervix
The lower part of the uterus through which instruments are inserted into the uterine cavity.
Catheter
A thin, flexible tube used for sampling or embryo transfer.
Genetic testing
Laboratory analysis that examines genetic activity in cells to help determine optimal conditions for treatment.
Cycle (menstrual cycle)
A regular hormonal process in a woman’s body preparing for possible pregnancy.
We are now offering patients the GERT - GENNET Endometrial Receptivity Test, which we have developed in our laboratories. The test allows a very detailed qualitative examination of the uterine lining and determines the so-called endometrial receptive window - the time when the uterine lining is ideally prepared for successful embryo implantation. It helps each patient individually to determine the most suitable time for embryo transfer.
GERT is recommended for women:
- repeated failures of embryo implantation
- problems with the uterine lining
- in repeated biochemical pregnancies
The examination is performed without anaesthesia by biopsy of the uterine mucosa, optimally in the cycle preceding the cycle when the embryo transfer is planned. The doctor inserts a thin catheter through the cervix and takes a sample; the procedure takes 10 to 15 minutes. The material obtained is then subjected to special genetic testing in the laboratory. Based on the results, it is evaluated whether the test was carried out at the ideal time or whether the implantation window is delayed (which is the case for about one in five women).
We offer the test as part of a comprehensive infertility treatment solution to our patients, please inquire with your coordinator. If you are not one of our patients yet and are interested in receiving treatment at the GENNET clinic, schedule a free initial consultation HERE.
