Repeat biopsy for preimplantation genetic screening (PGS) reanalysis does not adversely impact obstetrical outcomes

T-shaped uterine cavity morphology as assessed by three-dimensional ultrasound (3D US) is associated with lower sustained implantation rates and higher clinical loss rates following frozen embryo transfer

Inner cell mass and trophectoderm morphology impact the likelihood of achieving sustained implantation among expanded, euploid blastocysts

Total motile sperm count trend over time across two continents: evaluation of semen analyses from 119,972 infertile men

ABC trial: appraisal of body content. frozen embryo cycles are not impacted by the negative effects of obesity seen in fresh cycles

Only patients with obvious adenomyosis on three-dimensional ultrasound (3D US) are at increased risk of clinical loss following frozen embryo transfer

Initial serum human chorionic gonadotropin levels predict live birth outcomes following frozen embryo transfer with and without preimplantation genetic testing for aneuploidy (PGT-A)

Sperm DNA fragmentation (SDF) index on day of transvaginal oocyte retrieval (TVOR) does not correlate with the incidence of segmental aneuploidy in blastocysts analyzed with targeted next generation sequencing (NGS)

Worth the wait? Findings from culturing embros through day 7

Double embryo transfer of a euploid blastocyst after a failed single embryo transfer does not improve live birth rate but significantly increases the risk of twins
