In this week's Analytical Chemistry, scientists at Indiana University Bloomington report biochemical machinery that allows mouse sperm cells to follow the weakest of scents. Even when ovary extracts were diluted 100,000 times, some sperm cells still found their mark.
"Sperm are known to exhibit chemotaxis toward extracts from various female reproductive organs, but the role of chemotaxis in reproduction is not known," said IUB Associate Professor of Chemistry Stephen C. Jacobson. "The chemicals that actually attract sperm have not been identified. Systematic study of various compounds released by the female reproductive organs under various conditions might further our understanding of these processes."
