Sperm use the Secret Corkscrew power to swim swimming

When we get to know “birds and bees”, we learned that after sexual intercourse of two different sexes, sperm swim through the vagina, after the womb, and in the fallopian tube, where one fertilizes an egg issued by the ovaries. However, it turns out that sperm is not only to swim clock – they are racing via the female reproductive system, driven by rotating fluid veil that form like a rolling zipper.

Researchers from the University of Monash and the University of Melbourne used advanced photography to analyze 3D fluid movement around the sperm for swimming. As is detailed in a Ticket It was published on Tuesday in Cell Cell in the physical sciences, and the photography revealed that the one rosary sperm creates multiple swirls attached to the cell and revolves around each other in a simultaneous, promoting the push of sperm. This discovery sheds light on how CORKSCREW flow patterns affect sperm mobility and can have direct importance to reproductive sciences.

“While the sperm swims, its whip (the tail) generates a jail movement that creates a whirlpool liquid currents that can improve their push in the reproductive canal,” said Reza Nosrati, the co -author of the study and lecturer in the Department of Mechanical Engineering and Space in Monash, at the University of Monash, said statement. “What is really cool is how these” fingerprints “that resemble a whirlpool in the surrounding liquid attaches to the sperm’s body and rotates in sync, adding an additional payment.”

If you are having difficulty visualizing this exceptional payment method, this is somewhat similar to two columns revolving around each other. Or “Imagine to take a straight rubber band and wrap it in a spiral. Now, add another turn to create Superhelix-tightly wrapped structure,” explained Nosrati. “For sperm, this additional development in the liquid enhances their movement, and follow them during its tightening, allowing them to swim more efficiently.”

Nosrati and his colleagues claim that he was the first to issue both sperm tail and a three -dimensional flow field. Since this payment method may affect how sperm interacts with its surroundings, it may have important effects on fertility research. On a wider scale, picking up the movement of “young swimmers” can be closely related to understanding how other young swimmers, such as bacteria, and interacting with their environments, according to researchers.

“These perceptions help us to better understand fluid dynamics and the way sperm and other microorganisms move through different fluids,” explained Nukrati.

It turns out that making children actually revolve around the right moves – the whole way to the design of sperm.
