Two squirts of Krazy Glue may soon be all it takes to prevent pregnancies. Gregory Berkey, radiologist at the hospital of the University of Pennsylvania, administered small quantities of methylcyano-acrylate (MCA), into the fallopian tubes of 17 rabbits, blocking the tubes and preventing all rabbit pregnancies even 6 months after mating.
Berkey predicts that the risk of pregnancies would be less than 1 in 300. The technique has not been applied on women, pending federal approval. It is known to cause cancer in rats when introduced directly into the liver in high doses.
