For generations, who carried the unspoken weight when a couple faced difficulties conceiving? Historically, misconceptions ...

The winner of the first-ever Sperm Race has been crowned. Yep, you read that right. On Friday, two students set out to change ...

This important paper describes the regulatory pathway of rRNA synthesis by Meioc-Piwil1 in germ cell differentiation in zebrafish. Using the molecular genetic and cytological approaches, the authors ...

A 26-year-old American man has become the world’s first to receive a sperm-making stem cell transplant in a groundbreaking experiment aimed at reversing infertility. Jaiwen Hsu suffered from ...

This study provides valuable findings on the role of site-specific DNA methylation changes during spermatogenesis and their contribution to paternal epigenetic inheritance. The study proposes that ...

A man in his early 20s has received the world's first sperm-making stem cell transplant in a new procedure that could be groundbreaking for infertility treatment. Until now, the procedure had ...

In most cells, DNA is wrapped around proteins called histones, allowing it to be loosely packed and accessible for gene activity. However, in sperm cells, histones are replaced by protamines ...

A man who battled childhood cancer has received the first known transplant of sperm-producing stem cells, in a study aimed at restoring the fertility of cancer's youngest survivors. Jaiwen Hsu was ...

Nevertheless, such observations are complex─they require delicate samples kept in the liquid phase, low electron dose, and proper cell viability verification methods. Despite being highly demanding, ...

Just because a sperm is a strong swimmer doesn't necessarily mean it has the right amount of DNA, Dr. Lisa Lee told Newsweek.

More than a decade ago, scientists succeeded for the first time in generating primordial germ cells—the precursors of sperm and eggs—from embryonic stem cells, a process that led to functional sperm ...
