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...
Why Heat Stress Damages Sperm
Bacterial Vaginosis Affects One in Three Women: Groundbreaking Study Shows That Men are the Missing Link in the Chain
A groundbreaking study shows that bacterial vaginosis (BV), a condition that affects nearly one-third of women worldwide and leads to infertility, premature birth, and neonatal mortality, is in fact a...
How Certain Technologies Help Select the Right Sperm to Increase the Success Rates of In Vitro Fertilization
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...
New IVF Method Mimics Fallopian Tube Environment and Increases Sperm Viability
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...
