THE physics of how sperm navigate their way to an egg in mammals like humans and cattle are not well understood.
But the tendency for sperm to cluster together as they make their way upstream through the thickish, elastic-like fluid of the female reproductive tract is more than just random behaviour, scientists have found.
Think bicycle riders gathering in a ‘peloton’ formation to avoid wind resistance.
In a series of experiments using cattle sperm, researchers have found biological benefits for sperm working together that may have implications for fertility studies.
Despite the…
