Can sperm cells remain in the body and fertilise months after intercourse or can one only conceive one month at a time... Step into a world where the truth shines bright, and every headline is worth ...

Monash researchers have discovered that swimming sperm create swirling fluid vortices—shaped like rolling corkscrews—giving them an extra boost in the race to the egg. The study, published in ...

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 ...

His parents enrolled him in a study that was collecting and storing immature testicular tissue, and the sperm-forming stem cells in them, from young patients with the goal of eventually giving ...

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 ...

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 ...

A novel screening system developed at Kyoto University enables researchers to investigate sperm cell development and health at the molecular level. The study, published in Cell Genomics and led by ...

Men who use their cell phones frequently have lower sperm counts than men who don’t, according to new research published in Fertility and Sterility on Tuesday, offering a fresh insight into a ...

A study of nearly 3,000 Swiss men over the course of 13 years has shown a link between frequent cell phone use and a decrease in sperm quantity. What's more, today's 4G and 5G networks may have ...

The behavior of sperm cells is due, in part, to the individual DNA make-up of these cells, rather than only to the genetics of males, finds a team of scientists. Its results, which provide a new ...
