Recent studies investigating possible causes of male subfertility have largely focused on how lifestyle or environmental factors impact on the process of spermatogenesis. Markedly, fewer studies have investigated those risk factors that result in reduced sperm quality, such as poor sperm motility.

Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it. Barely years ago, it was considered a major scientific breakthrough when scientists came up with the idea that a fully formed, tiny human inhabited the head of each sperm — totally debunked and untrue.

New research done at Max Planck Gesellschaft has found that it isn't the concentration of chemicals released by the egg that control the speed of sperm, but a derivative of that. Our male readers will be happy to learn that their sperm is even smarter than they thought. It's been known that the egg releases chemicals that alter the concentration of calcium inside the sperm, which in turn changes how fast the sperm wag their tails. Turns out that it's not the concentration level itself that controls the speed, but the change in the concentration.
