100 000 quinacrine nonsurgical female sterilizations have been complet
ed over the past decade involving transcervical insertion of quinacrin
e (252 mg) as pellets by one, two or three monthly insertions. No deat
hs have been reported and serious complications are far fewer than for
surgical sterilization. Side-effects are mild and transient. Efficacy
has improved from 3 pregnancy failures per 100 women at one year to a
pproximately 1 by improved insertion technique and use of adjuvants. L
ong-term follow-up of early cases in Chile shows no increased risk of
cancer for this method. The main advantage of quinacrine sterilization
is its ability to raise contraceptive prevalence and thereby reduce m
aternal mortality and morbidity, especially in rural and urban slum ar
eas of developing countries. It should be made available as an option
to well informed women everywhere as an economical and safe permanent
family planning method.
