Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the ...

Embryo development begins with fertilisation of the ovum and proceeds through successive cleavage divisions, compaction into a morula, and differentiation into a blastocyst. At the blastocyst stage, ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

Lipid and fatty acid metabolism is central to the maturation of the oocyte and the subsequent development of the embryo. Fatty acids serve not only as dense energy substrates but also as precursors ...
