A Colombian poet and journalist has offered his testicles for sale to fund a trip to introduce Europeans to his work.

Raffael Medina Brochero yesterday told Radio Caracol he would sell them to the first person to agree to pay 375 million pesos ($A209,049) so that he could travel to Europe.

His testicles could be transplanted into a sterile person or used to make soup, said the 52-year-old poet, who has had 11 books published.
