When is PGT-A recommended for implantation failure?

PGT-A examines cells from an IVF embryo to look for extra or missing chromosomes before an embryo transfer. Repeated failed transfers can have several explanations, including embryo factors, uterine conditions, sperm factors, or timing. PGT-A addresses one part of that picture; it does not diagnose every cause of implantation failure and cannot predict whether a pregnancy will continue.

A fertility specialist may review embryo development, previous transfer details, ovarian response, uterine assessment, and the number of embryos available. Testing may be less useful when few embryos are expected, because biopsy and laboratory findings may leave no embryo suitable for transfer.

Ask for a review of the full history before deciding. The team can explain whether PGT-A is technically feasible, what a biopsy involves, how results are reported, and whether an untested transfer or another evaluation may be reasonable. Confirm how embryos are stored while results are processed and how the result will affect transfer planning.

Bring records from previous IVF cycles and ask whether both partners need additional assessment. Genetic counselling can help you weigh the possible information from PGT-A against biopsy, mosaic or inconclusive results, and the chance that no tested embryo is available.

Contact your fertility clinic promptly for heavy bleeding, severe pelvic pain, fainting, fever, or shortness of breath after a procedure or medication. Seek urgent medical care for sudden severe pain or collapse. These symptoms need assessment regardless of whether PGT-A is being considered.

Which possible cause of implantation failure would PGT-A address in my case? What other checks should happen first? How might the result change embryo-transfer choices?
