WASHINGTON -- It isn't only women who face a ticking biological clock when planning parenthood. New research has found that as men age, the quality of their sperm deteriorates, making it more likely they will have trouble becoming fathers and increasing the possibility of having a child with dwarfism. The study, led by Andrew Wyrobek of Lawrence Livermore National Laboratory and Brenda Eskenazi of the University of California, Berkeley, School of Public Health, appears in this week's online...

NEW YORK (Reuters Health) - Even though success rates in achieving pregnancy with frozen sperm are high, not many men take advantage of sperm preservation before they undergo cancer treatment that can make them sterile, Spanish investigators report. "Amazingly, the number of males banking sperm under these circumstances is extremely low in comparison with the number of newly diagnosed tumors in men younger than 40-45 years of age," Dr. Marcos Meseguer and his team note in an article in the...

LONDON (Reuters) - Toxic man-made industrial chemicals in the environment can damage sperm but do not seem to dramatically effect male fertility, scientists said on Thursday. They tested the impact of polychlorinated biphenyls (PCBS), so called gender bending chemicals which are blamed for causing genetic abnormalities in fish, but found no serious threat to health. The damage to sperm increased with the level of exposure to the chemicals in European men but did not have the same...

NEW YORK (Reuters Health) - Acupuncture may have a role as a treatment for certain types of male infertility, researchers suggest.

Dr. Jian Pei, from Christian-Lauritzen-Institut in Ulm, Germany, and colleagues assessed the benefits of acupuncture therapy in 28 men with unexplained sperm abnormalities, including malformed and...

By Will Boggs, MD NEW YORK (Reuters Health) - Contrary to earlier reports, everyday exposure to phthalates -- chemical plasticizers used extensively in household products and in certain medical products -- may not have harmful effects on fertility in young men, a new study shows. Previous studies suggested that low levels of phthalate exposure could adversely affect human semen, the authors explain in a report in Epidemiology, a medical journal, but high doses of phthalates are required to...

NEW YORK (Reuters Health) -- For men with low sperm counts, sexual abstinence -- but only for a day -- increases semen quality. More prolonged sexual abstinence may actually reduce sperm numbers, a new study indicates. "After only two days of abstinence, sperm from patients with male factor infertility initiate a process of quality degradation," Dr. Eliahu Levitas of Soroka University Medical Center in Beer-Sheva, Israel, and colleagues report. The findings are important for men trying to...

Findings have implications for middle-aged, wanna-be dads HealthDay News -- Older men have much more sperm DNA damage than young men do, which reduces their chances of fathering children, a Canadian study finds. The study of over 2,100 men found that injury to sperm DNA was significantly higher in men over 45 years old than in all younger age groups. Men over 45 years had double the sperm DNA damage compared with men younger than 30 years old. The research was presented Tuesday at the annual...
