Objective and subjective data for fertile period diagnosis in women: comparison of methods

The Authors have evaluated the reliability of various methods, both natural and biochemical, for the identification of the female ovulatory period in women with regular periods. They compared these methods among themselves and with echographical checking of ovulation. It emerged clearly from the study that the greatest reliability among the natural methods is obtained through the evaluation of the presence of cervical mucus, while among biochemical methods the best results are obtained by a semiquantitative colorimetric test. Brilliant prospects have also been opened by research on saliva.
