Embryos that are transferred after in vitro fertilization frequently fail to implant in the uterus; in
many cases, this failure is due to chromosomal abnormalities in the embryo. The current …

The frequency of multinucleated blastomeres (MNB) in 2-and 4-cell stage human embryos
was recorded immediately before embryo transfer using a high-power inverted microscope …

Preimplantation genetic testing for aneuploidy (PGT-A) is widely used in IVF and aims to
improve outcomes by avoiding aneuploid embryo transfers. Chromosomal mosaicism is …

Studies of human cleavage stage embryos, 3 days after fertilization of the oocyte, have
revealed remarkably high levels of chromosome abnormality. In addition to meiotic errors …

Objective To investigate the parameters of mosaicism and the biological mechanisms
leading to healthy pregnancies from mosaic embryo transfers. Design Prospective study …

Embryonic mosaicism occurs when two or more cell populations with different genotypes are
present within the same embryo. New diagnostic techniques for preimplantation genetic …

Purpose: To examine the rate of monozygotic twinning associatedwith blastocyst transfer
using commercially available, cell-free culture systems with unmanipulated blastocysts …

Details of 767 clinical pregnancies and 500 births from Bourn Hall are reported. All treated
patients included some over 40 years old, many with ovarian or uterine defects, male …

The aim of the present study was to investigate pregnancy rates ensuing from transfer of
