Igbo-Ora
Igbo-Ora is a town located in Oyo State, Nigeria, known colloquially as the "Twin Capital of the World." This reputation stems from the unusually high rate of twin births within the community. While the exact reasons for this phenomenon are still debated, it is widely attributed to dietary factors, particularly the consumption of yams and other local foods believed to contain compounds that stimulate multiple ovulations. Scientific research into this connection is ongoing, and various studies have been conducted to explore the potential links between diet and the prevalence of twinning in Igbo-Ora. The town attracts tourists and researchers interested in the unique phenomenon.
