Efecto de la refrigeración sobre la motilidad, integridad de membrana acrosomal y reacción acrosomal en espermatozoides caninos
(Universidad Nacional Mayor de San Marcos, 2005)
Preservation methods of spermatozoa using refrigeration have been developed for
canine sperm; however, the rate of fertilization is still low, possibly due to cell damage for
unknown reasons. The objective of this study ...
Video imaging of the sperm acrosome reaction during in vitro fertilization
(Landes Bioscience, 2011-07)
Mammalian spermatozoa become competent for fusion with oocytes while traveling through the female reproductive tract and the oocyte´s extracellular investments. Recent studies highlighted the molecular mechanism of the ...
Proacrosin/acrosin quantification as an indicator of acrosomal integrity in fresh and frozen dog spermatozoa
(ELSEVIER, 2006)
The scope of the present study was to evaluate the presence and activation of proacrosin/acrosin as a tool to determine the acrosomal status of fresh and frozen/thawed dog spermatozoa. Monoclonal antibody C5F11, directed ...
An intact acrosome is required for the chemotactic response to progesterone in mouse spermatozoa
(Wiley-liss, Div John Wiley & Sons Inc, 2017-04)
Mammalian sperm become fertilization-competent in the oviduct, during a process known as capacitation that involves the acquisition of the ability to exocytose the acrosome but also the chemotactic responses—both of which ...
Effects of pentoxifylline treatment before freezing on motility, viability and acrosome status of poor quality human spermatozoa cryopreserved by the liquid nitrogen vapor method
(Associação Brasileira de Divulgação Científica, 2007-07-01)
The objective of the present study was to investigate the effects of the direct addition of pentoxifylline (PF) to the ejaculates of men with poor sperm quality before freezing on post-thaw sperm motility, viability, ...
Effect of cryopreservation on the acrosomal integrity of viable alpaca spermatozoa evaluated by flow cytometryEfecto de la criopreservación en la integridad acrosomal de espermatozoides viables de alpaca evaluada mediante citometría de flujo

Effect of manganese supplementation on the membrane integrity and the mitochondrial potential of the sperm of grazing Nelore bulls
(Elsevier B.V., 2014-11-10)
The effect of dietary manganese (Mn2+) supplementation on the reproductive performance of Nelore bulls was evaluated by assessment of sperm membrane integrity. Sixty Nelore bulls (Bos taurus indicus) aged 18-20 mo were ...
