Abstract

Background: This study evaluated the contraceptive effectiveness of progesterone releasing intrauterine contraceptive devices (IUCD) and compared it with the Copper T device.

Methods: Seventy patients were selected in each group. Menstrual charts were maintained and data recorded at one, three, six months and one year after insertion of the device.

Result: One year follow up was completed by 66 patients in the Levonorgestrel Releasing Intrauterine System (LNG-IUS) group and 62 in the Cu T group. They were age, parity and education level matched. The mean duration of menstrual flow for the LNG-IUS group was 3.6 days and that for CuT group was 5.1 days (p>0.05). Insertion of LNG-IUS was found to be significantly difficult than the Cu T 380, with increased pain at insertion (p<0.05). There was no pregnancy in the LNG-IUS group and expulsion rates were low. The most significant difference was scanty periods and at times amenorrhoea in the LNG-IUS group. Termination rates for various reasons were almost equal in both groups.

Conclusion: Both devices were effective, safe, well accepted and tolerated. LNG-IUS scores high in patients with preexisting menorrhagia or dysmenorrhoea while Cu T 380 has advantages of lower cost, ease of insertion and comparable efficacy.
