Endometrial bleeding in the neonate, an event totally neglected by modern investigators, may play a role in the pathogenesis of at least early onset endometriosis and represent a potential source of endometrial stem cells. The bleeding is a well-established phenomenon occurring at the end of the first week, but is more often occult than visible. The structure and functional obstruction of the endocervical canal in the fetus at term suggest increased likelihood of retrograde flow of the endometrial shedding.
Comprehensive chromosome screening of trophectoderm with vitrification and later transfer in an unstimulated cycle may be the key to providing elective single-embryo transfer for the older woman undergoing IVF.
Polar body biopsy combined with array comparative genomic hybridization allows detection of maternal chromosomal aberrations. Although it has limitations, it can be seen as an alternative to blastomere and trophectoderm biopsy.
Aneuploidy screening of all chromosomes (preimplantation genetic screening) at each stage of embryo development, the techniques available, and the advantages and disadvantages of each technique are reviewed.
