متن کاملPregnancy outcomes in women with repeated implantation failures after intracytoplasmic morphologically selected sperm injection (IMSI)
BACKGROUND The purpose of this study was to compare laboratory and clinical outcomes of intracytoplasmic morphologically selected sperm injection (IMSI) and conventional intracytoplasmic sperm injection (ICSI) in couples with repeated implantation failures. METHODS A total of 200 couples with at least two prior unsuccessful ICSI cycles were enrolled: 100 couples were submitted to IMSI and 100...
متن کاملEvidence of prostaglandin involvement in blastocyst implantation.
Delayed-implantation mice were used to test for local implantation induction effects of prostaglandins E2 and F2 alpha. Evidence of implantation was gathered by microdissection of implantation sites and by scanning electron microscopy. Indomethacin was tested for the ability to interfere with the mechanisms of estrogen-induced, normal implantation. Both prostaglandins appear to have significant...
متن کاملDiverse Roles of Prostaglandins in Blastocyst Implantation
Prostaglandins (PGs), derivatives of arachidonic acid, play an indispensable role in embryo implantation. PGs have been reported to participate in the increase in vascular permeability, stromal decidualization, blastocyst growth and development, leukocyte recruitment, embryo transport, trophoblast invasion, and extracellular matrix remodeling during implantation. Deranged PGs syntheses and acti...
متن کاملBlastocyst gene expression correlates with implantation potential.
OBJECTIVE To investigate the role of the blastocyst in implantation failure. This study examined trophectoderm (TE) gene expression relative to pregnancy outcome. DESIGN Retrospective experimental study. SETTING Nonprofit research foundation. ANIMAL(S) Six-week-old BDF1 female mice. INTERVENTION(S) Hatching blastocysts underwent trophectoderm biopsy before single blastocyst transfer (on...
