Small defects in the male chromosome may be responsible for some cases of infertility, University of Minnesota doctors report in the New England Journal of Medicine. Dr. Jon Pryor and his team found that 7% of the 200 infertile men they studied were missing tiny pieces of their Y chromosomes, genetic material found only in males.

However, further study revealed that the deleted pieces did not always cause infertility. Out of six infertile men with the deletions, two had fathers with the same defect.
