Strong And Fast Sperms Are Bad
Weak sperms are bad, strong sperms are also bad, then how?
It is well known that having too few sperm can cut a man’s chances of fatherhood.
But some may be suffering because they are producing super-sperm which are too fast and powerful, scientists believe.
Evolutionary biologist Oren Hasson believes they race past the defences thrown up by a woman’s body so effectively that more than one sperm penetrates the egg.
This process, known as polyspermy, ruins the egg – and the chances of fertilisation.
In Britain, around one in six couples has trouble conceiving naturally and almost 35,000 women a year resort to IVF.Dr Hasson believes stressful lifestyles, infection and pollution alone cannot explain the high levels of infertility.
