Determination of ovulation through saliva

How does the ovulation affect the crystallization of saliva?

 

From years ago, scientists have been researching about the changes produced in the fluid of women during the different phases of their menstrual cycle to identify all the stages and predict better the best moment to get pregnant.

Dr. Papanicolau was one of them. He observed in the 1945 that the vaginal fluid crystalizes differently depending on the phase of menstrual cycle in which the woman was, but it wasn’t until 1969 when the gynecologist Dr. Biel Casals discovered that saliva has a different pattern of crystallization during the different phases of the ovulation cycle.

The crystallization of saliva is produced by the increase of estrogens (main female sex hormone) during the pre-ovulation phase, this results in an increase of the salinity of saliva (due to it is produced an optimum concentration of water, salts and sialomucins in it). This increment in the salinity produces changes in the saliva and crystalline structures that are visible with a microscope appear. The crystallization of saliva in the pre-ovulation phase approaches the ovulation, the period of about 48 hours in which woman is fertile.

Because of that, thanks to the crystallization of saliva during these days, ferns with a high number of branches can be seen.

Ovulation cycle with branches periods

When a woman is looking to get pregnant, we recommend:
  • Keep sexual relations when the branches is already looked during the pre-ovulation period, because although it isn’t the period fertile yet, spermatozoa have a 72 hours of life, and they will be in the woman organism until the ovulation will be produced.
  • Have sexual relations in alternate days from the branch are seen, with the main of the sperm has quality and then it covers all the fertile period
