Researchers say both mothers‑ and fathers‑to‑be play an important role in pregnancy and offspring outcomes.

In A Nutshell Men who ate more ultra-processed foods were more likely to face fertility challenges. Women’s intake didn’t ...

A study reveals that consuming ultra-processed foods may affect men's fertility and early embryo development. While men risk subfertility, women face smaller embryonic growth. This research, part of ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth ...

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

Healthy development The researchers found that higher variability in cell division leads to a more optimal arrangement of cells within the embryo, which promotes healthy development. "Our work ...

The early beginnings of an embryo as it transforms from a clump of cells to a tiny human is a bit of a mystery — scientifically speaking. We know many of the broad strokes, but there are a lot of ...

Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos. Scientists studying gene activity data of the early human embryo have discovered an ...
