Experts from the National Autonomous University of Mexico (UNAM) study in the movement of sperm in 3D to detect failures that prevent fertilization of the egg, in addition to contributing to the creation of new male contraceptives.
The coordinator of the Computer Imaging and Vision Laboratory of the UNAM Institute of Biotechnology (IBt), Gabriel Corkidi, pointed out that the application of basic knowledge could help to develop a technology to detect failures in sperm mobility, which cannot be observed with current technology.
He highlighted that after visualizing the swimming in 3D, it was established for the first time that the intracellular calcium of the human spermatozoon varies in a synchronized way with the movement of the tail or flagellum.
He explained that the calcium contained in different regions of the sperm has a direct relationship with the way it moves and is particularly important in the flagellum. So, if we can understand the way in which this element within the cell is related with its movement, it may be possible to understand some conditions that prevent fertilization.
The sperm has to travel through the female genital tract freely, with the technique used in the INAM it is possible to see that cell behaving in a similar way, he added.
The specialist explain that sperms are the male reproductive cell, formed by: a head , that allows it to enter the egg and which contains the DNA; the middle part, that contains mitochondria that supply it with energy; and a tail or flagellum, to move towards the egg.
