The role of dimethyl sulfoxide in the cryopreservation of Curimba (Prochilodus lineatus) semen

Abstract

A criopreservação de sêmen de Curimba (Prochilodus lineatus) é de importância ecológica e comercial. O objetivo deste estudo foi avaliar o efeito de diferentes concentrações (2, 5, 8 e 11%) de dimetilsulfóxido (DMSO) diluído em Betsville Thawing Solution (BTS) sobre a qualidade do sêmen de Curimba pósdescongelamento. Foram analisadas a taxa e período de motilidade, viabilidade espermática, integridade da membrana plasmática e do DNA, funcionalidade mitocondrial, e taxa de fertilização e eclosão. A membrana plasmática e a integridade do DNA a uma concentração de DMSO de 11% obtiveram melhores resultados que na concentração de 5% (p <0,05). Contudo, o tratamento de 5% de DMSO resultou em um aumento da latência e uma maior taxa de fertilização e de eclosão, com as demais qualidades do esperma sendo semelhante ao de sêmen fresco. Os resultados deste estudo indicam que 5% de DMSO é ideal para a criopreservação do sêmen Curimba

Cryopreservation of Curimba semen (Prochilodus lineatus) is ecological and commercial importance. The objective of this study was to evaluate the effect of different concentrations (2, 5, 8 and 11%) of dimethyl sulfoxide (DMSO) diluted in Betsville Thawing Solution (BTS) on the quality of post-thaw semen Curimba. We analyzed the rate and period motility, sperm viability, membrane integrity and DNA, mitochondrial functionality, and fertilization and hatching rate. The plasma membrane and DNA integrity of a DMSO concentration of 11% obtained better results than the concentration of 5% (p <0.05). However, treatment of 5% DMSO resulted in a longer latency and a higher fertilization rate and hatching, in other sperm quality equal to that of fresh semen. The results of this study indicate that 5% DMSO is ideal for cryopreservation of semen Curimba.
