Some like Akinyemi support the yam theory -- and point specifically to the reputedly high oestrogen content of agida, the local name for yam tubers.

"We eat a lot of okro leaf or Ilasa soup. We also consume a lot of agida. This diet influences multiple births," he said.

Others are not so sure.

"The real cause of the phenomenon has not been medically found," said Akin Odukogbe, a senior consultant gynaecologist with the University Teaching Hospital (UCH) in Ibadan, the nearest big town.

"But people attribute the development to diet," he continued, adding that studies have shown that yam can make women produce more than one egg which can be fertilised.

Chief nursing officer at the hospital Muyibi Yomi, who records a monthly average of five twins for every 100 births, puts it all down to genetics.

"If a family has a history of multiple births, this will continue from generation to generation," she said.

That should be good news for Yorubaland, where twins are regarded as a special gift from God and bearers of good luck, Akinyemi said.

"Twins are treated with affection, love and respect. Their birth is a good omen," he said.

But while many African cultures see twins as blessed, they often believe twins also have divine powers and the ability to harm those who cause them displeasure.

In pre-colonial times some communities used to kill twins and occasionally their mothers, believing a double birth was an evil portent and that the mother must have been with two men to bear two children at once. A Scottish missionary is credited with ending this practice.

In Yorubaland and indeed in large swathes of sub-Saharan Africa, twins are also believed to possess one soul between them. This belief accounts for a whole series of distinctive, and in some cases macabre rituals that are often country specific.
