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...
A groundbreaking study led by University of Colorado Anschutz Medical Campus researchers led by Nickole Moon, PhD, first author of the study and a student at CU Anschutz who is part of the research te...
During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. Certain proteins around which the DNA thread is wrapped - the protamines - play a...
Researchers at the University of Toronto have mapped the spatial distribution of around 700 long non-coding RNAs, also known as lncRNAs, in the testes. The team discovered many more lncRNAs in the tes...
