Researchers at Stockholm University have uncovered the hidden intricacies of how sperm develop from passive spectators into dynamic swimmers. This transformation is a crucial step on the path to ferti...
Using the model organism Caenorhabditis elegans, biologists have identified molecular mechanisms that cause DNA damage in sperm and contribute to male infertility after exposure to heat. In humans, th...
Motile sperm are difficult to collect using conventional cell sorters because they are susceptible to physical damage. As part of a research collaboration between Kumamoto University and Kyoto Univers...
Sperm cells are highly specialized cells with only one goal: to fertilize an egg. On the road to fertilization, sperm must travel a long journey to the female's fallopian tube, avoiding several deadly...
The success of in vitro fertilization depends on many factors, one of which is sperm viability. A recent study by the University of Illinois Urbana-Champaign documents a new method for selecting viabl...
A Yale-led research team has discovered how a naturally occurring biological mechanism found in mammals can prevent sperm from interacting with an egg, thus standing in the way of fertilization. The d...
Researchers at Crick have discovered which genes on the Y chromosome regulate sperm development and affect fertility in male mice. This research could help to understand why some men do not produce en...
Obesity is a major global health issue and continues to rise. In addition to a variety of chronic diseases such as diabetes and cardiovascular disease, obesity is also associated with reduced sperm qu...
