Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

The work appears in Cell. "Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said ...

Australian scientists created the first kangaroo embryo via IVF, a breakthrough in species conservation. Using eastern grey kangaroo specimens, the technique involved injecting a single sperm cell ...

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to ...

Oxytocin, a hormone already known for its role in childbirth, milk release, and mother–infant bonding, may have a newfound purpose in mammalian reproduction. In times of maternal stress, the hormone ...

A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that ...

Statements in English by Samuel Ojosnegros Martos, Principal Investigator of the Bioengineering for Reproductive Health Group at the Institute for Bioengineering of Catalonia (IBEC), and leader of the ...
