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...
Taurine Deficiency in Sperm Leads to Male Infertility
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 Development of the Embryo is the Key to a Healthy Lifestyle

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...
Naturally Occurring Mechanism Impairs Fertility

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...
Clarifying the Role of Y-Chromosome Genes in Male Fertility
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...
Inflammation in the Testicles Could Explain the Link Between Obesity and Reduced Fertility
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...
Groundbreaking Research Sheds Light on the Hidden Effects of Stress on Sperm
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...
What Role Certain Proteins Play in Sperm Production
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...
