Human sperm can tell when they've taken a wrong turn - and try to get back on track, according to a researcher.
However, other experts suggest it is highly unlikely that sperm have any sort of memory or intelligence.
Researchers at University Hospital Zurich have found that sperm appear to have hidden abilities.
They allowed hundreds of sperm to swim towards a t-junction offering a left or right choice. As expected, half of them headed right, and half headed left.
Dr Peter Brugger, the neurobiologist who conducted the tests suggested that the sperm have an innate ability to "correct" the original right turn by choosing to turn left later on. This keeps them heading in as straight a course as possible.
