Copper levels & reactive oxygen species in uterine flushings in copper intrauterine contraceptive device users.
Copper levels were estimated in the uterine flushings in 15 copper 'T' 200 device acceptors. There was a statistically significant difference in the preinsertion and one week post insertion values (P < 0.001). This also corresponded to a high level of generation of reactive oxygen species. The levels of reactive oxygen species were similar to preinsertion values at 4 and 12 wk. The copper values declined over the 3 months but were still higher at 12 wk as compared to preinsertion levels and this difference was statistically significant. Hence addition of copper to the intrauterine device besides enhancing the contraceptive efficacy, perhaps also plays an important role in microbicidal activity and helps in overcoming the infection introduced at the time of insertion.
