The ultrastructure of the vaginal fluid of cows at oestrus was analysed by scanning electron microscopy. Samples of vaginal fluid were collected from 7 normally cycling and healthy cows, 3 to 4 years of age, in oestrus. Evaluation of the patterns of crystallization was used as a previous assessment of the quality of the samples. SEM images revealed a structure made up of non-oriented filaments constituting a network with a three-dimensional arrangement. These filaments were of different diameters and ranged between 50 and 400 nm. Mesh size, defined as the minimum distance measurement between strands, ranged between 2 to 8 μm.
