When high levels of estrogen are present, such as just before ovulation (or during pregnancy), the cervical mucus forms fern-like patterns due to crystallization of sodium chloride on mucus fibers. This pattern is known as arborization or 'ferning'. When progesterone is the dominant hormone, as it would be in the
It is also higher in electrolytes, which results in the "ferning" pattern that can be observed in drying mucus under low magnification; as the mucus dries, the salts crystallize, resembling the leaves of a fern. [12] The mucus has a stretchy character described as Spinnbarkeit most prominent around the time of ovulation. [26]
Like amniotic fluid, blood, semen, vaginal secretions in the presence of infection, [9] soap, [10] urine, and cervical mucus [8] also have an alkaline pH and can also turn nitrazine paper blue. [9] Cervical mucus can also make a pattern similar to ferning on a microscope slide, but it is usually patchy [9] and with less branching. [8]
Postcoital test. The postcoital test (PCT), also known as the Sims test, Hühner test , Sims–Hühner test, or cervical mucous penetration assay is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix. The PCT examines sperm survival in cervical mucus during the pre-ovulatory period and ...
During this window, ferning structures occur in cervical mucus as well as saliva. Computerized fertility monitors, such as Lady-Comp, are available under various brand names. These monitors may use BBT-only systems, they may analyze urine test strips, they may use symptothermal observations, they may monitor the electrical resistance of saliva ...

The cervical mucus plug (CMP) has a viscoelastic structure which is a gel like. The CMP occupies the cervical canal during pregnancy. It displays potent antimicrobial properties against bacteria such as Staphylococcus saprophyticus, S. aureus, Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecium, Streptococcus pyogenes, and S. agalactiae.
The mucus may be tinged with blood and the passage of the mucus plug is called bloody show (or simply "show"). As effacement takes place, the cervix then shortens, or effaces, pulling up into the uterus and becoming part of the lower uterine wall.
