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 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.
