Quantification of bovine sperm separation by a swim-up method. Relationship to sperm motility, integrity of acrosomes, sperm migration in polyacrylamide gel and fertility
Quantification bovine sperm separation swim-up method
2009/2/23
The number of bovine spermatozoa separated in a swim-up procedure was quantified using an electronic cell counter. In an initial test of the swim-up procedure, non-frozen sperm samples with differen...
Compromised sperm protein phosphorylation after capacitation, swim-up, and zona pellucida exposure in teratospermic domestic cats
Cat sperm teratospermia tyrosine phosphorylation zona pellucida
2009/2/16
Tyrosine phosphorylated proteins recently have been found in mouse and human spermatozoa. Our objectives were to (1) determine if domestic cat spermatozoa also express tyrosine phosphorylated pro...
Relationship between morphology and motion characteristics of human spermatozoa in semen and in the swim-up sperm fractions
sperm morphology motility patterns swim-up separation
2009/2/6
In this study, the authors evaluated the morphology pattern and motion characteristics of human spermatozoa before and after swim-up separation. Samples were divided into two, morphologically diff...
Teratospermic and normospermic domestic cats：ejaculate traits, pituitary-gonadal hormones, and improvement of spermatozoal motility and morphology after swim-up processing
domestic cat sperm morphology teratospermia
2009/2/6
Electroejaculate traits, testicular volume, and circulating FSH, LH, and testosterone concentrations were compared between two populations of domestic cats consistently producing either a high (grea...
Ram Sperm Selection by a Dextran/Swim-Up Procedure Increases Fertilization Rates Following Intrauterine Insemination in Superovulated Ewes
Sperm quality reproductive efficiency IUI
2008/12/22
The objective of this study was to compare the efficacy of 2 dextran/swim-up media to increase the sperm quality parameters and the maintenance of these parameters at 15°C and 30°C over 6 hours. A...
Spontaneous DNA Fragmentation in Swim-Up Selected Human Spermatozoa During Long Term Incubation
DNA damage necrosis phosphatidylserine translocation reactive oxygen species sperm
2008/12/19
The origin and the meaning of DNA fragmentation in ejaculated human spermatozoa are not yet clear, although some hypotheses have been proposed. In the present study, we used investigated sperm DNA fra...
Aneuploidy and chromosome breakage in swim-up versus unprocessed semen from twenty healthy men
Aneuploidy chromosome breakage unprocessed semen twenty healthy men
2008/12/2
Toxicological and epidemiological studies have investigated several factors that are believed to induce cytogenetic damage in human sperm cells in an effort to estimate heritable risk to future gene...
