Human sperm quality and lipid content after migration into normal ovulatory human cervical mucus containing low numbers of leukocytes.
The aim of this study was to investigate whether a relationship exists between the presence of low numbers of leukocytes in normal ovulatory cervical mucus and sperm quality and lipid content after migration. The percentages of live, motile and morphologically normal spermatozoa, movement parameters assessed by computer-aided sperm analysis (CASA), and ionophore-induced acrosome reaction measur...
متن کاملAntimicrobial activity of human cervical mucus.
The antibacterial activity of human cervical mucus (CM) was examined on standardized microbial colonized agar plates (agar diffusion test). In parallel, the lysozyme content of CM was determined by means of a turbidimetric test system in aliquots of the same CM specimens. Suspensions of living lyophilized Micrococcus lysedeikticus were used as bacterial substrate. Testing was performed in a tot...
متن کاملGlobular structure of human ovulatory cervical mucus.
Human cervical mucus is a heterogeneous mixture of mucin glycoproteins whose relative concentration changes during the ovulatory phases, thereby producing different mucus aggregation structures that can periodically permit the transit of spermatozoa for fertilization. In preovulatory phase, mucus is arranged in compact fiber-like structures where sperm transit is hindered. Previously, through o...
متن کاملSperm counts in enzymatically liquefied cervical mucus: quantitative validation using donor cervical mucus.
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...
متن کاملHuman sperm swimming in a high viscosity mucus analogue.
Remarkably, mammalian sperm maintain a substantive proportion of their progressive swimming speed within highly viscous fluids, including those of the female reproductive tract. Here, we analyse the digital microscopy of a human sperm swimming in a highly viscous, weakly elastic mucus analogue. We exploit principal component analysis to simplify its flagellar beat pattern, from which boundary e...
