Scientists have found microplastics in human semen and follicular fluid, according to new research on a small group of adults ...

Hanna and Żernicka-Goetz, with their respective teams, worked on separate model embryos that demonstrate human development through 14 days after fertilization.

The guinea pig serves as an alternative model to study human preimplantation development. Nature Cell Biology , 2025; 27 (4): 696 DOI: 10.1038/s41556-025-01642-9 Cite This Page : ...

Researchers hope these model embryos will shed light on the “black box” of human development, the period following 14 days after fertilization, which is the agreed limit for scientists to grow ...

The Japanese experiment may change the science of human reproduction. The first successful in-vitro fertilization, in 1978, made it possible to conceive an embryo outside the body.

But so far animal studies suggest these model embryos do not have the same potential as a human embryo and would not survive if implanted. "This suggests something is missing," Dr Limnios says.

The European Society of Human Reproduction and Embryology was founded in 1985 by Robert Edwards (University of Cambridge) and J. Cohen (Paris), who felt that the study and research in the field of ...

A new study shows that microplastics have been discovered within human reproductive cells. The Cool Down reports that the study, carried out in Italy, found microplastics in 14 of the 18 samples ...

A report released in September by the US National Academies of Science, Engineering, and Medicine points out that almost no research has been done on human reproduction in space, adding that our ...

A new study reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development.
