Nigeria missing from the list of top 10 countries with the largest penis in the world

According to research of top 10 countries with the largest penis in the world conducted by the University of Ulster in 2017, African countries dominated top 20 and other contries were Asian contries, which means Africans have big cassava.

But Nigeria men that always make noise that they have big cassava was not included, which got me thinking. Why didn't they include Nigeria? So Nigerians that always make noise of big cassava don't have big cassava, that's a shame.
