Trophectoderm Biopsy

A new method for embryo evaluation, the trophectoderm biopsy, is gaining traction. Unlike traditional biopsies that take individual cells, this approach removes several cells from the placenta-forming layer (trophectoderm) of a 5-7 day old embryo (blastocyst stage). These cells, while not directly contributing to the fetus, hold valuable genetic information about the developing life. This makes the biopsy appealing as it avoids harming the embryonic tissue itself while still providing crucial insights.
