MONTREAL, July 23, 2013 /CNW Telbec/ - Why does only one sperm cell out of 100 million get through to fertilize the egg? According to the investigations of Jackson C. Kirkman-Brown, from the Reproductive Biology and Genetics Research Team at the University of Birmingham, UK, multiple physical factors can affect the behaviour and success of the sperm in fertilizing the egg. Kirkman-Brown will present a talk on this subject this week at the 46th annual meeting of the Society for the Study of Reproduction at the Palais des congrès de Montréal.
Many reproductive biologists have proposed the chemotactic or "attractive egg" hypothesis for fertilization, for which there is little concrete evidence. Most have neglected to consider the role played by the viscosity of the mucous layers (which coat the entire genital tract and through which sperm must swim) in both sperm selection and ongoing modulation of their behaviour. Dr. Kirkman-Brown addresses this topic in his research, which focuses upon a greater understanding of physical, physiological, and cell signaling processes that regulate the function of sperm and eggs. This covers everything from understanding how a sperm recognizes an egg and other crucial events in fertilization, to how the sperm negotiates the physical obstacle course it faces in the female body.
The presentation will take place during the 46th Annual Meeeting of the Society for the Study of Reproduction, hosted in Montréal by the Réseau Québécois en Reproduction, from July 22 to July 26 in the Palais des Congrès de Montréal. http://www.ssr.org
