The manufacturer of the entire world supply of quinacrine pellets, used to chemically sterilize women in developing nations, said it will no longer make the pellets. The decision by Sipharm Sissein Ag, a closely held firm based in Sissein, Switzerland, follows a one page article in the Wall Street Journal about the use of pellets to sterilize more than 100,000 women in about 20 countries. The Journal article reported instances in which quinacrine sterilizations were performed without women's knowledge or against their will.
