Having five best friends ‘can boost women’s fertility’

New research has revealed that women who have a close-knit circle of five friends could boost their fertility.

Professor Robin Dunbar, from Oxford University, UK, revealed that his research suggests that the stress of having to maintain too many friendships may have an effect on female hormones and therefore their ability to reproduce.

Discussing his findings at the American Association for the Advancement of Science conference in Boston, Massachusetts, Prof Dunbar said: “The stresses you incur destabilise the menstrual system endocrinology and very quickly lead to infertility.

“What primates have had to do is develop these very intense small scale coalitions, that sit at the base of all their social systems which effectively buffer you against social stresses.”

According to the research, women are able to maintain their friendships by phone conversations, while men have to meet up in person to stay friends.ADNFCR-2094-ID-801832605-ADNFCR
