Abstract

Background: The aim was to compare the efficacy and acceptability of two Internet-supported fertility-awareness-based methods of family planning. Study design: Six hundred and sixty-seven women and their male partners were randomized into either an electronic hormonal fertility monitor (EHFM) group or a cervical mucus monitoring (CMM) group. Both groups utilized a Web site with instructions, charts and support. Acceptability was assessed online at 1, 3 and 6 months. Pregnancy rates were determined by survival analysis. Results: The EHFM participants (N= 197) had a total pregnancy rate of 7 per 100 users over 12 months of use compared with 18.5 for the CMM group (N= 164). The log rank survival test showed a significant difference (p<.01) in survival functions. Mean acceptability for both groups increased significantly over time (p<.0001). Continuation rates at 12 months were 40.6% for the monitor group and 36.6% for the mucus group. Conclusion: In comparison with the CMM, the EHFM method of family planning was more effective. All users had an increase in acceptability over time. Results are tempered by the high dropout rate.
