A new study of the human sperm by an researcher in Applied Mathematics has revealed that the design of the sperm influences fertility than sperm count.
The findings are based on a virtual sperm model developed by Hermes Gadelha, Lecturer in Applied Mathematics, University of York. In this model, the researchers varied the features of the tail based on tails of different species.The human sperm has to traverse through thick cervical mucuos, deadly acids of the vagina to reach the egg to be fertilized. It was found in the virtual model that human sperm could easy move in liquid like water and thicker liquids similar to cervical mucuos.
The findings may enable the identification of fittest sperms in In Vitro Fertilization (IVF) and sperm count is a poor predictor of success in fertility. Stress, lifestyle changes and certain diseases have increased male fertility in many countries and hence the importance of this research finding.
