Scientists at the University of Liverpool have found that male fruitflies experience a type of 'paranoia' in the presence of another male, which doubles the length of time they mate with a female, despite the female of the species only ever mating with one male. Females in many species of animal have multiple mates and males have evolved particular reproductive characteristics to ensure their sperm are successful when in competition with the sperm of other males. Adaptations include physical...

Fertility scientists have created artificial sperm using stem cells for the first time in a breakthrough that could lead to new treatments for infertile men. In the revolutionary experiments, the Japanese researchers at Kyoto University have made sperm from scratch, and, for the first time, successfully used it to produce healthy baby mice. The landmark research paves the way for new drugs for infertility -- a condition that affects one in six couples. When the sperm cells were transplanted...

Research could lead to techniques to improve fertilization in humans In new research that could have implications for improving fertilization in humans and other mammals, life scientists studied interactions between individual sperm and eggs in red abalone, an ocean-dwelling snail, and made precise chemical measurements and physical models of these interactions. They are the first scientists to do so. By simulating the natural habitat of the abalone in the laboratory, the scientists were able...

The loss of a protein that coats sperm may explain a significant proportion of infertility in men worldwide, according to a study by an international team of researchers led by UC Davis. The research could open up new ways to screen and treat couples for infertility. A paper describing the work is published July 20 in the journal Science Translational Medicine. The protein DEFB126 acts as a "Klingon cloaking device," allowing sperm to swim through mucus and avoid the immune system in order to...

Vitamin D is important for optimal reproductive function in both animals and humans. It has long been known that serum vitamin D level is important for reproductive function in various animals, but now researchers from the University of Copenhagen and Copenhagen University Hospital have shown that this relationship can also be demonstrated in humans. A new study conducted in 300 normal men showed a positive correlation between the percentage of motile sperm and serum vitamin D levels. The...

Egg cells failing to properly arrange chromosomes Washington State University researchers have confirmed a critical step in cell division that results in age-related miscarriages and birth defects, including Down syndrome. Writing in the upcoming issue of the journal "Current Biology," the researchers say they recreated the conditions in which an egg cell will continue to undergo cell division without properly arranging its chromosomes, creating offspring with aneuploidy, or an abnormal...
