In the United States, an estimated 645,000 men ages 20 to 50 have azoospermia, a condition in which no sperm are present in their ejaculate. Now, scientists are testing a potential treatment: ...

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm production, new research has revealed. In a landmark study published today ...

While men may be able to have children much later than women, doing so could come with an increased risk of inherited disease for their children. Researchers from the Wellcome Sanger Institute have ...

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 ...
