Summary
For process of fertilization to occur both in natural and in IVF conditions certain minimal amount of sperm cells are required. That minimal amount is species specific. Based on previous hypothesis in the oscillatory model of mammalian fertilization the theory of sperm penetration mechanism is proposed trough biomechanical model. In this model each sperm is consider as a material particle with certain mass, with three spherical coordinates, certain oocyte contact surface and velocity. In order to predict the penetration area on the surface of an oocyte an algorithm that calculates the maximum and minimum penetration forces of radial and tangential components of the force generated by the different sperm cells that influence the oocyte surface at the same time interval is generated.
