Men's diets, in particular the amount and type of different fats they eat, could be associated with their semen quality according to the results of a study published online in Europe's leading reproductive medicine journal Human Reproduction today (Wednesday). The study of 99 men in the USA found an association between a high total fat intake and lower total sperm count and concentration. It also found that men who ate more omega-3 polyunsaturated fats (the type of fat often found in fish...

Yale researchers have discovered how the "guardian of the genome'' oversees quality control in the production of sperm – and perhaps in many other cells as well. The research published online Feb. 16 in the journal Current Biology opens up the potential of developing new forms of birth control and fertility treatment – and even new ways to combat many forms of cancer. Sperm and other cells go through a sort of inspection process triggered by a key regulatory gene, p53, which...

Wi-Fi technology could be dangerous to a man´s sperm quality, suggests a new study published in the journal Fertility and Sterility. Argentinean scientists, led by Conrado Avendano of the Nascentis Center for Reproductive Medicine in Cordoba, describe in their report how they got semen samples from 29 healthy men, placed a few drops from those samples under a laptop with a Wi-Fi connection, and then used the laptop to do various everyday tasks. Within four hours of use, 25 percent...

Scientists have discovered exactly how a human egg captures incoming sperm to begin the process of fertilization. The new study could help future couples who suffer from infertility. The international team of researchers found that a specific kind of sugar molecule makes the outer coat of the egg "sticky," which helps the egg and sperm bind together. "The details we've discovered here fill in a huge gap in our knowledge of fertility and we hope they will ultimately help many of those...

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...

A new study has shown that a surgical technique called microdissection testicular sperm extraction (TESE) can effectively locate and extract viable sperm in more than one-third of adult male childhood cancer survivors who were previously considered sterile due to prior chemotherapy treatment. As a result, many of the men were subsequently able to father children with the help of in vitro fertilization. The findings offer a new option for many cancer survivors who want to have children but...

A new study published in the International Journal of Andrology reveals that semen quality has significantly deteriorated during the last ten years in Finland, a country that previously was a region with high sperm counts. At the same time, the incidence of testis cancer in the Finnish population showed a remarkable increase, following the worrying trends observed in several countries in Europe and the Americas. Led by Jorma Toppari, MD, PhD, of the University of Turku, researchers examined...

A study said that most exercise appears to have little relationship with the quality or quantity of sperm, but men who bike at least five hours a week have fewer and less active sperm than men who did not exercise. Lauren Wise at Boston University, who led the study, said that research among competitive athletes has linked biking to genital or urinary problems and poor semen quality. "However, we were uncertain whether we would find an association among a sample of men engaged in more...
