A clinical sexologist, Dr. Lindsey Doe, has explained ways the sperm is capable of revealing if one’s partner is cheating on them.
She said that up to 40 per cent of male ejaculation is made up of so-called “kamikaze” or “fighter sperm” designed to prevent another man’s sperm from fertilizing the egg.
According to her, when a man suspects that his partner is being unfaithful, the number of these aggressive sperm increases to tackle the perceived threat.
Explaining the phenomenon, Doe said, “Researchers have looked into the microscope and seen that maybe we have what are called kamikaze sperm; killer sperm; fighter sperm.
“This is because 40 per cent of sperm that is in an ejaculate are actually designed to fight off another man’s sperm.
“This means the fighter sperm isn’t designed to fertilize the egg. Instead, it’s included purely to prevent another male’s sperm from doing so.”
Dr. Doe further described this method of preventing other sperm from reaching the egg as “blocking.”
She said that “The fighter sperm use their tails as coils to set up traps by weaving them together to create walls and barricades.”
Doe added “that some fighter sperm would go and attack any sperm it sees as a threat in order to kill them.
“These fighter sperm are referred to as ‘kamikaze sperm.’”
Doe explained that, “When males suspect their partners are not being monogamous, Doe said, their body will produce more ‘fighter sperm’ as the threat is perceived to be greater.
“This does the job of increasing the level of protection against sperm from other males; but it can significantly reduce the number of sperm whose job it is to fertilize the egg and therefore reduce the chances of the female getting pregnant at all.”
