When do sperm start to swim

That device gathered information about sperm movement at the level of submicron resolution, smaller than one-millionth of a meter.

Each sperm cell moved like a spinning top, rotating around its own axis, and also around a middle axis. Human spermatozoa are not the only microorganisms to function this way—mouse and rat sperm and the flagella of Chlamydomonas , a type of green algae, also have asymmetric movements and an underlying asymmetric shape.

To truly understand sperm, it must be observed in its intended, selective environment—the female reproductive tract, which scientists also need to study more. Doctors think that this new discovery showing how sperm move can help treat infertility , a condition that affects roughly 50 million couples globally. Male biological factors are solely responsible for an average of 20 to 30 percent of cases of infertility, and contribute to about 50 percent over all.

Still, these statistics are biased based on countries where data from IVF and other fertility treatments are common, so sperm factors could be even more significant than recorded. The more accurately scientists can understand the fundamental molecular biology of sperm motility, the better doctors may be able to address motility issues associated with infertility, says Tanrikut.

Giving sperm a boost as they near their target. The switch that transforms sperm into super-swimmers in the race towards the egg has been identified at last. The discovery could lead to drugs that boost male fertility and new forms of male contraceptives. It could also explain why zinc deficiency and smoking cannabis can impair male fertility. Sperm are relatively immobile before ejaculation. But once they get inside the female reproductive tract, they start swimming and speed up as they near the egg.

This enabled them to monitor the flow of protons across the membrane. When the channels open, protons stream out of the sperm cells, causing the pH inside the cell to rise and the sperm to swim.
