Repeated Implantation Failures
Regrettably, some couples suffer from repeated failures of IVF cycles, either not achieving a positive result or early pregnancy failing to progress. The investigations for this are
Maternal Blood Tests
- Clotting (thrombophilia) screen – small clots in the blood have been identified as a possible cause of a pregnancy to fail to progress
- Immune screen – increased levels of natural killer cells (white blood cells) and autoantibodies (antibodies attacking specific organs) have also been suggested as a cause for the repeated failure of cycles.
- 3D ultrasound
- Hysteroscopy/endometrial scratch
- Endometrial Receptivity Array
- Sperm DNA fragmentation
- CGH (comparative genomic hybridization)
- Embryoscope.
