Cryopreservation of Prochilodus lineatus semen: effect of cryoprotectants combination

Abstract: The study was conducted with the objective of comparing the toxicity and the effect of the combination of intra and extracellular cryoprotectants in curimba Prochilodus lineatus sperm cells subjected to cryopreservation. Semen from 19 males were analyzed and diluted in four solutions comprise of intra and extracellular cryoprotectants in the following combinations: methanol+lactose, methanol+egg yolk, DMSO+lactose and DMSO+egg yolk. A portion of the diluted semen was frozen while the remaining fraction was kep… Show more

“…However, none of the treatments exceeded 50% of sperm morphological alterations. Vasconcelos et al () did not verify significant differences between major and minor morphological changes when evaluating the effects of different cryoprotectors on P. lineatus semen freezing using the standard method (“dry‐shipper + nitrogen cylinder”). However, these authors did not evaluate freezing curves and used dry‐shipper (uncontrolled cooling rate) as a cryopreservation method.…”

“…Alguns estudos demonstraram que a presença de carboidratos (sacarose, lactose e frutose), em diluidores foram benéficos para criopreservação de sêmen de peixes (VASCONCELOS et al, 2018), bovino (FARIAS et al, 2019) e equinos (HEMPEL, 2019). Nosso estudo acredita que o Ca 2+ pode ter uma participação indireta com o processo de motilidade espermática, uma vez que não conseguimos descrever o mecanismo de ação desse elemento, nas condições deste estudo.…”
