Formant frequency as an effective treatment for non-invasive assessment of menstrual cycle

The World Health Organisation (WHO) established in 1972 a special programme to assess and improves the safety and efficacy of the existing method of fertility regulation. This task force supported research on variety of methods based on determination of the fertile period. An attempt was made by the authors to identity physical parameters which could be used to precisely and reliably predict ovulation using a bioengineering approach (a noninvasive one). The approach is based on a noninvasive technique that involves monitoring the formant frequency-response of a lady´s sound utterances. It was found that all 52 Hindi segmentals were able to represent the menstrual cycle. For the ease in analysis the authors have chosen only seven representative words. It is concluded that with this new approach the woman herself can determine the fertile phase of her menstrual cycle. The suggested new method will be helpful for a family planning programme as well as for health care due to menstrual irregularity and illness
