“…A similar finding has been reported in the stallion [34]. In the boar, an increase in the M540-YP stainability has been reported as early as 100 seconds after exposure to bicarbonate [5].…”

“…Merocyanine 540 (M540) detects bicarbonate-induced changes in lipid packaging and distribution within the sperm plasma membrane [34], which are thought to be very early changes in the capacitation process [5]. As membrane fluidity increases, more M540 is able to intercalate into the membrane, thereby acting as a useful marker for membrane destabilization [5,11,[35][36][37][38][39].…”

“…Yet, capacitation‐like changes (cryocapacitation) occur in spermatozoa subjected to cooling and/or cryopreservation, and these changes are similar to true capacitation (Bailey et al, 2000; Green and Watson, 2001). A substantial proportion of boar spermatozoa may undergo protein tyrosine phosphorylation during the cryopreservation process (Kumaresan et al, 2011, 2012a,b). Recently, Harayama et al (2010) also reported a relationship between the level of tyrosine phosphorylation in frozen‐thawed semen and tolerance to frozen storage in bulls.…”

“…O colesterol tem múltiplos efeitos sobre as membranas plasmática e acrossomal, incluindo estabilização, redução da permeabilidade, o que melhora as características morfológicas de membrana permitindo interações célula-célula, que influencia a transição de fase da membrana, proporcionando microambientes adequados (química e/ou física) para proteínas associadas, e servindo como um antioxidante (CROCKETT 1998). Também é relatado que o processo de criopreservação pode levar à criocapacitação do sêmen equino (ANDRADE et al, 2012), suíno (KUMARESAN et al, 2011), bubalino (KADIRVEL et al, 2009KUMAR et al, 2014) e ovino (GILLAN et al, 1997;ROVEGNO, et al, 2013 A teoria de formação de cristais de gelo intracelular é, no entanto, controversa e contradita em diversos estudos, os quais não os observaram em espermatozoides bovinos (RAPATZ et al, 1966), suínos HERNANDEZ et al, 2007), equinos (MORRIS et al, 2007) e humanos (MORRIS, 2006) Com isso, observa-se que o processo de congelação, apesar de importante para a utilização do sêmen em protocolos de inseminação artificial, possui pontos negativos para a célula. É notório que esse processo leva a diminuição de parâmetros espermáticos como a motilidade, atividade respiratória, estado das membranas e qualidade do DNA (GILLAN et al, 2004).…”
