What to expect from PGT-A for implantation failure

PGT-A examines selected embryo cells for chromosome numbers. It does not identify every genetic or structural problem, and it cannot explain every reason an embryo fails to implant. The process usually includes ovarian stimulation, egg collection, fertilisation, embryo culture, biopsy, laboratory testing, and freezing while results are reviewed.

A result may be described using laboratory terms such as euploid, aneuploid, or mosaic. Your fertility specialist explains what the result means in your clinic and whether transfer, further testing, or another plan is appropriate. Implantation failure can have causes unrelated to embryo chromosome findings.

Ask how many embryos may be available for testing, what happens if there are none suitable for biopsy, and how results affect transfer planning. Share previous IVF records and any known family or genetic information. Discuss medication instructions, the timing of a frozen transfer, consent, and whether genetic counselling is recommended. Give yourself space to process uncertain or unexpected results.

During stimulation or after egg collection, contact the clinic urgently for severe abdominal pain, marked swelling, vomiting, faintness, or breathing difficulty. After transfer, seek advice for heavy bleeding, severe pain, fever, or feeling acutely unwell. Emotional distress after repeated treatment deserves support too, particularly if sleep, eating, or safety is affected.

Ask what PGT-A can add in your circumstances, how mosaic findings are handled, what other causes of implantation failure will be assessed, and how results change the next transfer decision.
