The world’s first unisex contraceptive – made from olives

Eating handfuls of olives will not prevent pregnancy, but a chemical found within them can stop a sperm from reaching an egg, the Daily Mail reports.
The natural compound, also found in grapes and mangos, could replace the morning after pill if taken within five hours of unprotected sex.
It could also become the first unisex pill, able to be taken by both men and women without the current side-effects of heart disease, blood clots and depression.
The chemical, lupeol, works by stopping the sperm’s “power kick”, where its tail is whipped up forcefully to propel it towards and into the egg. Another chemical, primisterin, which is found in the thunder god vine used in Chinese medicine, has the same effect.
Researchers at the University of Berkeley in the US say it could be available within two years for women to take before or after sex, and within four years for men.
Co-author Dr Polina Lishko said: “It is not toxic to sperm cells – they still can move. But they cannot develop this powerful stroke, because this whole activation pathway is shut down. This is a potentially safer morning after pill, regular pill, and a future male contraceptive. Essentially it is a future version of a unisex contraceptive.”
Fertility expert Allan Pacey, professor of andrology at the University of Sheffield, said:
“This is probably one of the most innovative approaches to male contraception, allowing men to take equal responsibility for family planning that we have seen in a long time.
“Scientists have been tinkering with different kinds of hormonal contraceptives for men for 30 years and they have not yet got them to marketplace, so we really need a new kind of approach like this.”
