Anthony van Leeuwenhoek, who once studied his own ejaculate hundreds of years ago, concluded that human spermatozoa move very quickly and rapidly, floating in a chaotic manner, from side to side. The invention of the microscope allowed medicine to make a big leap forward and begin to develop in a new direction for itself, then bacteria and other microorganisms were discovered.
Leeuwenhoek described his discovery in the field related to the study of spermatozoa, which he called "impudent animals": "They moved forward thanks to the movement of their tails, such as the movement of a snake or eel swimming in water." For centuries, this judgment has not been challenged. However, now, using the latest modern instruments and 3D microscopy, scientists have managed to see and record the real movements of the sperm.
In fact, according to study author Hermes Gadelch, head of the Polymaths laboratory at the Department of Engineering Mathematics at the University of Bristol in the UK, sperm do not move from side to side, but rotate in a "tailspin", like otters spinning in water as they play. According to scientists, this discovery in the future will help solve problems with the reproductive health of men, in particular the problem of infertility.
