A failed euploid embryo transfer means a chromosomally normal (PGT-A–tested) embryo was placed in the uterus but did not result in a pregnancy. It is a specific, common scenario: after two or three such failures, the problem shifts away from embryo chromosomes toward the endometrium and other receptivity factors. Importantly, “euploid” sharply lowers — but…
After a day-3 embryo arrest, the consult can feel overwhelming and you may walk out with more emotion than information. These ten questions are designed to turn a vague “it just didn’t work” into a structured review you can act on. Pick the ones most relevant to your cycle, write the answers down, and bring…
Changing your IVF protocol after a day-3 embryo arrest is sometimes the right move — but it should be a decision, not a reflex. The key question is whether your cycle showed a modifiable problem (low fertilization, untested sperm DNA, an obviously poor response) versus a non-modifiable one (embryo chromosome error, which no stimulation tweak…
Yes — sperm DNA fragmentation (DFI) can contribute to embryo development problems, but its role is more established for later stages (blastocyst formation, implantation, and miscarriage) than for a pure day-3 arrest. Standard semen analysis (count, motility, morphology) often looks normal while DFI is high, which is why this factor is so frequently missed after…
A day-3 embryo arrest often gets labeled, in forums and in our own heads, as “my eggs are bad.” That shortcut is understandable — but it is usually wrong as a conclusion from a single cycle. “Egg quality” is a statistical, population-level concept: it describes the probability that eggs in a cohort are competent, not…
Before you change anything for your next IVF cycle, the highest-value move is to review the data you already have — not to assume the worst. A day-3 arrest is a signal to investigate, not automatic proof that “your eggs are gone” or that your clinic failed you. The most useful pre-next-cycle review looks at…
When embryos stop growing, the embryology report is your most concrete source of truth — but it is written in shorthand. This guide explains the usual fields so you can understand what happened in your cycle, ask better questions, and avoid misreading a normal variation as a failure. The two numbers that matter most are…
Embryos that stop dividing around day 3 usually reflect a loss of “developmental competence” — the embryo’s built-in ability to keep cleaving and reach the blastocyst stage. The single most common driver is chromosome abnormality (aneuploidy) inside the embryo itself, and the risk rises steeply with maternal age. Other contributors include egg (oocyte) factors such…
