This project applies both theoretical and experimental fluid                    mechanics and rheology to a fundamental problem in the biology of               sperm motion and eventual fertility.  The problem involves the                  interaction of swimming sperm with biopolymeric fluid secretions                found within the female reproductive tract, primarily cervical                  mucus.  Spermatozoa must successfully migrate through such                      biopolymeric gels in order to reach the egg.  At present,                       relatively little is known about the fundamental mechanics of the               sperm-mucus interaction: i.e. of the material properties of mucus               which sperm experience; and of the hydrodynamics of sperm                       swimming in such obviously non-Newtonian fluids.  The proposed                  project, in order to address an important biomedical question,                  will undertake studies that address these two questions.
