In 1968, abortion by the instillation of saline solution accounted for 28% of those procedures performed legally in San Francisco, California. Intrauterine instillation (of all kinds) declined from 10.4% of all legal abortions in the U.S. in 1972 to 1.7% in 1985, falling to 0.8% of the total incidence of induced abortion in the United States during 2002, and 0.1% in 2007.
This passage describes the decline of intrauterine instillation as a method of abortion in the United States between 1968 and 2007, highlighting its decreasing prevalence over time.
