Artificial insemination using cryopreserved semen is a common management tool of the contemporary livestock producer. However, cryopreservation is detrimental to sperm function and fertility, kill...
Sperm surface proteins after capacitation. Expression of vitronectin on the spermatozoan head and laminin on the sperm tail
Sperm surface proteins vitronectin spermatozoan head laminin sperm tail
2009/2/11
Several integrins recognize as ligands proteins containing the Arg-Gly-Asp (RGD) sequence, such as fibronectin, vitronectin, and laminin. It has been previously demonstrated that oligopeptides con...
Longitudinal study of semen quality of unexposed workers：sperm head morphometry
morphology morphometry sperm head statistics tolerance intervals
2009/1/5
As part of a longitudinal study of human semen characteristics of unexposed workers, sperm head measurements were made using image analysis (Image Technologies Corp., Deer Park, NY). Morphometry was...

2008/12/26
This study was conducted to investigate the relationships between results of computer-assisted semen analysis (spermatozoal motility and sperm head morphometry) and fertility of boars. In addition, ...
Functional Significance of the Sperm Head Morphometric Size and Shape for Determining Freezability in Iberian Red Deer（Cervus elaphus hispanicus）Epididymal Sperm Samples
cryopreservation morphology postmortem recovery

In order to examine the predictive value of determining the sperm head shape, the acrosomal size, the presence of acrosomal vacuoles, and the challenged acrosome reaction (AR) on the outcome of a stan...
Involvement of Cytoplasmic Free Calcium in Boar Sperm: Head-to-Head Agglutination Induced by a Cell-Permeable Cyclic Adenosine Monophosphate Analog
Capacitation BAPTA thapsigargin fluo-3 Ca2+-ATPase
2008/12/18
When boar spermatozoa are incubated in a medium designed for in vitro fertilization, many of them become agglutinated at the acrosomes. We previously reported that bicarbonate and cyclic adenosine...
