Plastics Chemical BPA Tied to Poor Sperm Quality
Posted 29 Oct 2010 by Drugs.com
THURSDAY, Oct. 28 – Men with high amounts of the controversial plastics chemical bisphenol-A (BPA) in their urine also tend to have impaired semen quality, a new study of factory workers in China reveals. The research, funded by the U.S. National Institute of Occupational Safety and Health, found high urine levels of BPA to be significantly associated with a drop in sperm concentration, overall sperm count, sperm vitality and sperm motility. Although prior work with mice and rats had uncovered troubling associations between BPA exposure and damage to the male reproductive system, the current finding is the first drawn from research involving people. "Compared with men without detectable urine BPA, those with detectable urine BPA had more than three times the risk of lowered sperm concentration and lower sperm vitality, more than four times the risk of a lower sperm count, and more than ...

Dietary Fats Seem to Affect Sperm Quality
Posted 26 Oct 2010 by Drugs.com
TUESDAY, Oct. 26 – Men who eat foods containing a lot of saturated fats – think burgers and fries – and monounsaturated fats may be harming their sperm, a new study by Harvard researchers suggests. Men consuming a lot of these types of fats may be producing fewer and less active sperm. Conversely, men who consume foods containing healthier, polyunsaturated fats such as omega-3 and omega-6 fatty acids (fish, whole grains) may be producing healthier sperm, the study suggested. "We observed significant relationships between dietary fat and semen quality," said lead researcher Dr. Jill Attaman, an instructor in obstetrics, gynecology and reproductive biology. "This shows an association between modifiable lifestyle factors, specifically nutrition, and male fertility potential." The reasons for the apparent connection aren't clear, Attaman said. But, she added, different types of fats are ... Read more

Genetic Glitch Tied to Disrupted Sperm Production
Posted 1 Oct 2010 by Drugs.com
THURSDAY, Sept. 30 – The cause of male infertility often escapes experts, but scientists have found a genetic mutation that appears to disrupt sperm production. "This may be the most frequent single gene defect that is associated with male infertility known to date, with 4 percent of men with unexplained severe spermatogenic failure carrying a mutation," said Kenneth McElreavey, a researcher at the Pasteur Institute in France and a member of the team that made the discovery. The gene, NR5A1, has been associated with other reproductive problems, McElreavey noted. "Studies in the last 10 years have linked mutations involving NR5A1 to defects in the development of external genitalia in boys," he said. "Last year, we identified mutations in this gene associated with a range of reproductive problems in women." The new study links mutations in the same gene with reduced sperm count, which ...
