Summary
Human cervical mucus exhibits four distinct morphological types (L, S, P, G), varying in crystallization and ultrastructure. These mucus types are secreted from different cervical zones and change throughout the menstrual cycle.
Area of Science:
- Reproductive Biology
- Gynecology
- Microscopy
Background:
- Human cervical mucus morphology was investigated using light microscopy (LM) and scanning electron microscopy (SEM).
- Samples were collected from the cervical lumen and secretory zones of the cervical mucosa.
Purpose of the Study:
- To morphologically characterize different human cervical mucus types.
- To analyze variations in mucus from the cervical lumen and secretory zones.
Main Methods:
- Examined 230 samples from 195 women using LM and SEM.
- Assessed 'ferning' phenomenon in air-dried and glutaraldehyde-fixed samples.
- Studied cervical lumen and crypt secretions via SEM.
Main Results:
- Identified four distinct morphological mucus types: L, S, P, and G.
- Observed these types in both dried and fixed sample preparations.
- Demonstrated heterogeneity in cervical lumen mucus.
Conclusions:
- Cervical lumen mucus is morphologically diverse, containing variable secretion proportions across the menstrual cycle.
- Different mucus types exhibit unique crystallization and ultrastructural patterns, linked to glycoprotein network arrangement.
- Distinct secretory zones within cervical crypts produce specific mucus types.
