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 ...

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 ...

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 ...

A man in his early 20s received a transplant of his own sperm-producing stem cells, which had been frozen since his childhood, in an attempt to regain fertility. Doctors are waiting to see if the ...

WASHINGTON (AP) _ Embryonic stem cells have been encouraged to grow into sperm cells for the first time, Japanese scientists report. The work is very preliminary, and was done in the laboratory with ...

Generational wounds may live in our genes. New research suggests that childhood trauma leads to a difference in the epigenetics of a sperm cell, which can impact a child's development and also be ...

In-vitro gametogenesis, or IVG, is a concept that sounds like science fiction but is slowly becoming a real possibility. Imagine creating eggs or sperm from skin cells, all outside the body. It’s a ...

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...
