The post-coital test evaluates the penetration of spermatozoa into cervical mucus; it relies on subjective measurements and therefore lacks precision. Enzymatic liquefaction of cervical mucus allows sperm concentration to be measured in post-coital test samples, but the reliability of such measurements is not known. Donor cervical mucus was used as a model to test the accuracy and sensitivity o...

This study was planned to determine the physical and chemical properties of cervical mucus collected during normal and induced estrus of Ossimi ewes. Estrus of 14 Ossimi ewes were induced by intravaginal sponges for 14 days. Estrus was observed one to two times in ewes after estrus induction with a range of 17-21 days. Cervical mucus samples were collected from all ewes (14 each for induced and...

BACKGROUND In 1996, an estimated 15,700 new cases of cancer of the uterine cervix and 4,900 deaths from this disease were expected to occur in the United States. In a recent international study, human papillomavirus DNA was found in more than 90% of cervical tumor specimens examined, irrespective of the nationality of the patients from whom the samples were obtained. Although infection with hum...

The objective of the experiment was to study the changes in different characteristics of cervical mucus of Murrah buffaloes in relation to occurrence of estrus. The Murrah buffaloes maintained at Livestock Research Centre (LRC), ICAR-NDRI, Karnal were classified into three groups viz. heifers, primipara and pluripara. Cervical mucus was collected on the day of estrus prior to the artificial ins...

BACKGROUND The aim of this study was to separate bactericidal proteins from healthy female cervical mucus. METHODS Cervical mucus was collected and dissolved in 1% acetic acid. The antimicrobial activity of acid-soluble extracts was detected by gel overlay assay against Escherichia coli ATCC 43827. The extracts showed considerable amount of antibacterial activity with a clearly visible band. ...

The indirect immunofluorescent technique performed on spermatozoa provides a suitable method for detecting spermatozoa1 antibodies in cervical mucus. Blood sera and preovulatory cervical mucus samples from I3 women with infertility of unknown ori...

Molecular characterization of sperm proteins and their immunoreactions to sera from subfertile/infertile animals may give deeper insight to the immunological reason of infertility. The purpose of this study was to characterize antigenic sperm proteins by reacting with blood serum and cervical mucus of variably inseminated heifers/cows using immunoblotting and immunofluorescence techniques. Immu...

The objective of the present study was to determine if exposure of cervical mucus to air during specular examination could modify mucus pH. Detection of changes is justified because of their possible interference with sperm-mucus interaction, since an acidic pH is unfavorable to sperm penetration and is associated with infertility due to the cervical factor. Twenty women with good quality mucus...

Bovine spermatozoa have been shown to metabolize exogenous substrates both aerobically and anaerobically (Mann, 1964). Fructose (Mann, 1946) and sorbitol (King & Mann, 1958) have been unequivocally identified in seminal plasma, but evidence for the presence of metabolizable substrates in the cervical mucus rests on much less secure foundations. A number of reports that glucose is present in cer...

OBJECTIVE To determine whether cervical mucus aspiration before intrauterine insemination (IUI) has any effect on clinical pregnancy rates. METHOD The outcomes of 186 IUI cycles in 95 consecutive patients in whom mucus was aspired prior to IUI were compared retrospectively with those of 1057 IUI cycles in 505 women. RESULTS The pregnancy rate was 15.1% (28 pregnancies for 186 cycles) in the...
