Gumming up the works

 
Published: Sunday 30 April 1995

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.
