Cervical mucus was collected from 24 normal (control) women, and 45 cases fitted with Cu T200 IUDs. Glucose concentration was measured by spectrophotometry before and after insertion of the IUDs. In the control group, glucose concentration at midcycle was 1.802 +or- 0.235 mg/gm wet weight cervical mucus. Pre- and postinsertion mean values in Cu T200 users were 0.746 +or- 0.149 mg/gm and 0.487 +or- 0.045 mg/gm of mucus respectively. This decrease in mucus glucose concentration in Cu T200 users may be a factor by which this device affects sperm migration at the cervical level.
