The movement of human spermatozoa in cervical mucus.
Movement characteristics of freely swimming spermatozoa were studied with high-speed cinemicrography. At 21 degrees C, flagellar beat frequency was higher in midcycle human cervical mucus than in native semen or Tyrode's solution; the beat shape differed, possessing diminished amplitude and wavelength. Although the spermatozoa swam straighter in the mucus, the progressive swimming speeds did no...
متن کاملEvaluation of Discontinues Puresperm Gradient in Separation of X And Y Bearing Human Spermatozoa by Fluorescent in Situ Hybridization (FISH)
Introduction: To evaluate the 8 layer discontinues puresperm gradient in separation of human spermatozoa according to sex chromosomes by fluorescent in situ hybridization (FISH). Material and Methods: This study was carried out on three patient referring to Royan fertility and infertility center. Semen analysis was assessed according to WHO criteria. Each sample was divided into two aliquots, ...
متن کاملRelationship of cytoplasmic droplets to motility, migration in mucus, and volume regulation of human spermatozoa.
A significantly greater percentage of motile than immotile spermatozoa bore droplets at the osmolality of semen and cervical mucus. The percentage of spermatozoa with droplets was not significantly correlated with the osmolality of semen or the extent of cell swelling in response to quinine in hypotonic medium. Droplets appeared slightly more frequently (ie, were more obvious) in the presence o...
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...
