Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton's third law of motion to do so. To figure out how they slither through substances that should, in ...

A new study shows that lab-grown sperm cells can be derived from stem cells. July 9, 2009 — -- The face of infertility-- in literature, in the media, in advocacy groups -- is so predominantly ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

Two new studies uncover how DNA folding controls sperm cell development. Researchers identified proteins that rearrange genomic architecture, setting cellular memory and fate. This 3D genome mapping ...

Germ cells pass DNA to the next generation and undergo massive reorganization of their DNA packaging to generate totipotency, or the ability to differentiate into any cell type. Understanding the ...

Even then, it only takes one sperm to fertilise an egg, with only around 200–500 sperm typically surviving the journey to reach it. Added to that, it turns out that a woman's uterus can actually taste ...

(CNN) — Scientists have long questioned whether human papillomavirus, or HPV, infections in men could affect their sperm health and fertility. Now, an early study finds that high-risk HPV infections ...

When we talk about a biological clock ticking, it usually means the pressure women feel to get pregnant before a certain age. It's linked to the decline in eggs (ova) and fertility as females age.
