The journey of early pregnancy begins with fertilisation and continues as the embryo travels to the uterus. Timing plays a ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

The earliest days of pregnancy depend heavily on the health of the egg and sperm. Week 3 marks the stage when fertilisation occurs, and rapid cell division begins. Egg and sperm quality influence how ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Researchers at Vanderbilt University have developed a new embryo culture dish that significantly improves microscope imaging, a longstanding barrier in in‑vitro fertilization (IVF). Traditional 3D ...
