NEW YORK (Reuters Health) - A gene mutation that causes formation of abnormally shaped sperm results in male infertility, according to a report in the advance online publication of Nature Genetics.The mutation, which is located in the aurora kinase C gene (AURKC), is associated with large-headed sperm with too many sets of chromosomes and multiple flagella, or tails, which allow the cells to move. Previous research identified only deletions of the Y chromosome as a cause of altered sperm formation, the authors explain.>>> Discuss This Story
