Competition between sperm is fierce – they all want to be the first to reach the egg to fertilize it. A research team from Berlin has shown in mice that the ability of sperm to move forward depends ...
In vitro fertilization (IVF) is a time-consuming and often stressful procedure, but it is increasingly being used to help couples realize their dream of having a child. But how does stress affect the ...
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...
