Abstract
Carbonic anhydrase activity is present in human cervical mucus throughout the normal menstrual cycle. Lowest activity occurs in the ovulatory phase. A similar pattern of activity is seen in the presence of either an 'inert' or copper-releasing intrauterine contraceptive device (IUCD). The overall levels of activity are not significantly altered by the presence of either type of IUCD. A cyclic pattern of activity is retained even though endogenous ovarian function is suppressed by combined oestrogen-progestogen oral contraceptives.Keywords
