The unusual, coiled-ribbon pattern was significantly more complex than sperm swimming patterns we observed last year , all findings that could have implications for fertility, health and our understanding of the microscopic world. This paper proposes an automatic framework based on concatenated learning approaches to segment the external and internal parts of the sperms. A highly effective tail is needed in order for a sperm to be able to swim, and for an egg to be fertilised. The research was started in order to see what human sperm tails look like in 3D.

The external parts of the sperms are segmented using two convolutional neural network CNN models which produce the probability maps of the head and the axial filament regions.

By transmitting the genetic information to the next generation and marking the beginning of a new life, the encounter between female and male gametes at fertilisation is one of the most fundamental processes in biology. Reproduction, Fertility and Development Google Scholar. We had to develop special microscopy techniques that could achieve the necessary high resolution and fast frame rates. In summary, our results illustrate and quantify the parameters of an entirely new swimming pattern — chiral ribbons — and could help us better understand the statistical behavior of various microswimmers, possibly shedding light onto the biophysics of their 3D motion.
