Israeli scientists have shed light on an unusual factor behind fertility problems in women.

Researchers at the Weizmann Institute have found that the substances found in face-creams and some food and drink can reduce women’s chances of pregnancy.

Professor Nava Dekel made the discovery after finding that antioxidants can cause ovulation levels in female mice to drop “precipitously”.

She said the research showed that “more caution should be taken when administering such substances”

She said: “These findings could prove useful to women who are having trouble getting pregnant.”

However Professor Dekel added that the research could also have another positive consequence for women.

She said: “Certain antioxidants might be effective means of birth control that could be safer than today’s hormone-based prevention.”

The professor and her team will now investigate their findings further.
