“…A STUDY of certain rheological properties of human cervical secretion was undertaken at the suggestion of G. W. Scott Blair, D.Sc., whio had observed certain significant rheological phenomena in bovine cervical secretion when working on the problems of the time of ovulation and pregnancy diagnosis in cows, at the National Institute for Research in Dairying, Reading. Scott Blair (1937) described an emptying-tube viscometer for use with rheologically complex materials. Scott Blair, Folley, Malpress and Coppen (1941) found that the viscous and elastic properties of bovine cervical se3cretions vary regularly during the cestrous cycle ( fig.…”

The object of this Communication was to demonstrate two rheological properties of cervical secretion, namely, flow-elasticity and Spinnbarkeit. There is evidence that these properties undergo cyclic variation during the menstrual cycle and bear relation to ovulation, to penetrability by spermatozoa and to pregnancy. By means of the menstroscope, designed by Scott Blair, flow-elasticity or elastic recoil can be measured. It is found to be most marked at the time of ovulation when also the mucus is thin and transparent. Spinnbarkeit—the capacity of liquids to be drawn into threads—is also capable of accurate measurement by drawing away a coverslip placed on a blob of mucus which is drawn out into a long thread. It is also more marked at the time of ovulation and is almost absent in pregnancy. Plasticity and tack, two further properties of cervical mucus, were also discussed. It is believed that these tests will prove to be of value in diagnosis of ovulation and in the study of sterility.

“…Secretion belongs to materials that do not give straight-line flow-curves and therefore show anomalous viscosities (see Note 1). Scott Blair et al (1941) It occurred to us, that since ovulation normally occurs immediately after cestrus in cows, it might well be that the phenomenon flow-elasticitv is associated directly with the cestrin secretion which normally accompanies ovulation (Seguy and Vimeux, 1933, correlated an increase in urinary folliculin with visual evidence of ovulation by inspection of the ovaries at laparotomy in women). We were therefore led to investigate the possibilities of flow-elasticity of human cervical secretion, as an indication of the time of ovulation in women.…”

ABSTRACT.-The object of this Communication was to demonstrate two rheological properties of cervical secretion, namely, flowelasticity and Spinnbarkeit. There is evidence that these properties undergo cyclic variation during the menstrual cycle and bear relation to ovulation, to penetrability by spermatozoa and to pregnancy. By means of the menstroscope, designed by Scott Blair, flow-elasticitv or elastic recoil can be measured. It is found to be most marked at the time of ovulation when also the mucus is thin and transparent. Spinnbarkeit-the capacity of liquids to be drawn into threads-is also capable of accurate nmeasurement by drawing awav a coverslip placed on a blob of mucus which is drawn out into a long thread. It is also more marked at the time of ovulation and is almost absent in pregnancy. Plasticity and tack, two further properties of cervical mucus, were also discussed. It is believed that these tests will prove to be of value in diagnosis of ovulation and in the study of sterility.
