Introduction: Fertility signals from the fertile window can improve the prediction, detection and diagnosis of the fertile phase
in subfertile woman. The effectiveness of the use of such signs in subfertile women can help to get pregnant. This article includes
subfertiles women who incorporated fertility biomarkers of cervical secretion fertility, in the range of left kurtosis of the curve of
the fertile phase.
Material and Method: This report includes 30 sub-fertile women with an average age of 34.3 years (sem 0.96); range: (26-46
years). An individual approach was adopted through the evolution of biophysical parameters of viscoelasticity and transparency
of cervical secretion. The progression of the biomarkers was located in the fertile window, with the purpose of improving the
perception in the recognition of the evolution of the biophysical properties of the cervical mucus.
Results: Pregnancy was obtained in 33% of the cases, in which 27% (8/30) were women under 35 years of age. Pregnancy was
obtained in two cases in women older than 35 years. The success rate to achieve a pregnancy was higher in the group of women
under 35 years of age. Ten cases of patients with male factor were included, achieving two cases of pregnancy equivalent to 6.6% of
the sample in the group of patients under 35 years of age.
Conclusion: Subfertile couples with risk factors such as age, dilation in time to look for a pregnancy, and sperm of poor quality,
may be candidates to consider advancing gestational desire, or consider protocols that help to detect the fertile window through
observation of the evolutionary pattern of cervical secretion.
