The Bioself 110 is a hand-held electronic device that combines the BBT and calendar methods of fertility regulation for planning or preventing pregnancy. A pilot study was undertaken in three centers in the United Kingdom to evaluate the Bioself 110 as a contraceptive aid. This paper deals with 1238 cycles from 131 women. Only one unplanned pregnancy occurred where a volunteer correctly used the Bioself 110 and had intercourse on a supposedly "safe" day. A second pregnancy was experienced by a volunteer who incorrectly used the device and had intercourse on what she though was a "safe" day. Another 11 unplanned pregnancies occurred due to barrier method failures, as well as 11 pregnancies where the volunteers knowingly had unprotected intercourse during the fertile phase. There were five planned pregnancies. The Bioself 110 was correctly used in 71% of the cycles studied. Eighty-four percent of the volunteers indicated that they were satisfied with the Bioself 110 after six to twelve cycles of use. It was concluded that the Bioself 110 can serve as an effective family planning aid and should be added to the menu of contraceptive methods available to women today.
Bioself 110是一种手持电子设备，它结合了基础体温法和日历法来调节生育，用于计划怀孕或避孕。在英国的三个中心进行了一项试点研究，以评估Bioself 110作为一种避孕辅助工具的效果。本文涉及131名女性的1238个月经周期。只有一名志愿者在正确使用Bioself 110的情况下，在一个被认为是“安全”的日子发生性行为后意外怀孕。另一名志愿者在错误使用该设备且在她认为是“安全”的日子发生性行为后怀孕。由于屏障避孕法失败，还发生了另外11例意外怀孕，以及11例志愿者在排卵期明知未采取保护措施而发生性行为导致的怀孕。有5例是计划内怀孕。在所研究的周期中，71%的周期正确使用了Bioself 110。84%的志愿者表示，在使用六至十二个周期后，他们对Bioself 110感到满意。研究得出结论，Bioself 110可作为一种有效的计划生育辅助工具，应纳入当今女性可用的避孕方法清单。
