The global average birth rate for twins is around 12 per 1,000 births, but in Igbo-Ora it is reported to be about 45 per 1,000. According to oral folklore, the village was founded in the 14th Century by an exiled prince of the Oyo Kingdom, who was told to make specific offerings to the Yoruba gods in pairs and in return, the village was blessed with twins. Many locals though put their fertility down to a dish called “ilasa”, made from okra leaves. Researchers are investigating whether natural chemicals in the local food, like ilasa or perhaps even the local yams, might make women produce multiple eggs. Prof Akinola Kehinde Akinlabi, rector of the Oyo State College of Agriculture and Technology based in Igbo-Ora, thinks genetics may have more to do with it.
