Antisperm antibodies modify plasma membrane functional integrity and inhibit osmosensitive calcium influx in human sperm.
BACKGROUND The hypo-osmotic swelling (HOS) test evaluates the ability of the functional sperm plasma membrane to stretch following cell swelling when exposed to hypo-osmotic solutions. Sperm samples with low HOS scores show low fertilization and pregnancy rates during assisted reproductive techniques, though data are controversial. The aim of this study was to compare the results of the HOS tes...
متن کاملTreatment of human spermatozoa with seminal plasma inhibits protein tyrosine phosphorylation.
It has long been known that seminal plasma contains factors that influence the fertilizing capacity of spermatozoa in many different ways. However, little is understood of the biochemical cascades triggered when spermatozoa and seminal plasma interact. In this study, we examined how incubation with seminal plasma affected protein tyrosine phosphorylation in human spermatozoa. Increased protein ...
متن کاملeffects of cryopreservation on plasma membrane glycoconjugates of human spermatozoa
background: cryopreservation has some detrimental impacts on sperms surface molecules. modification of the sperm surface molecules can affect on fertility rate. one of the important surface molecules are glycoconjugates. objective: the objective of this study was to evaluate the changes of content of the glycocalyx after standard cryopreservation procedure. materials and methods: forty five h...
متن کاملGlycodelin-A interacts with fucosyltransferase on human sperm plasma membrane to inhibit spermatozoa-zona pellucida binding.
Fertilization depends on successful binding of the spermatozoa to the zona pellucida of the oocyte. Glycodelin-A inhibits spermatozoa-zona pellucida binding. Previous data showed that glycodelin-A receptor(s) and zona pellucida protein receptor(s) on human spermatozoa are closely related. Using a chemical cross-linking approach, the glycodelin-A-sperm receptor complex was isolated. The receptor...
متن کاملDetermination of membrane integrity of canine spermatozoa
Semen samples from 9 sexually mature dogs of different breeds, aged from 1 to 5 years were used. Quality of sperm was evaluated using the following parameters: progressive motility (subjective), then structural and functional integrity of spermal membrane (supravital colouring (eosine/nigrosine) and HOS test). The majority of HOS reactive or swollen spermatozoa was placed in a hypoosmolar solut...
