“…As noted above, some scientists suggested using fish spermatozoa freezing model to investigate the mechanisms of why cryoprotectant-free vitrification for human ejaculates is better than conventional freezing and vitrification with cryoprotectants [15,16,50].…”

Sperm cryopreservation has been widely used in assisted reproductive technology (ART) and has resulted in millions of live births. Two principal approaches have been adopted: conventional (slow) freezing and vitrification. As a traditional technique, slow freezing has been successfully employed and widely used at ART clinics whereas the latter, a process to solidify liquid into an amorphous or glassy state, may become a faster alternative method of sperm cryopreservation with significant benefits in regard to simple equipment and applicability to fertility centers. Sperm vitrification has its own limitations. Firstly, small volume of load is usually plunged to liquid nitrogen to achieve high cooling rate, which makes large volume sample cryopreservation less feasible. Secondly, direct contact with liquid nitrogen increases the potential risk of contamination. Recently, new carriers have been developed to facilitate improved control over the volume and speed, and new strategies have been implemented to minimize the contamination risk. In summary, although sperm vitrification has not yet been applied in routine sperm cryopreservation, its potential as a standard procedure is growing.

“…Despite its benefits, vitrification exposes spermatozoa to physiologically inappropriate conditions and, consequently, leads to cell damage due to osmotic and thermal shock, biochemical changes in seminal plasma and oxidative stress; therefore, it reduces sperm quality (Kopeika & Kopeika, 2008) and, consequently, sperm's capacity to fertilize. Some factors required for the vitrification process may be deleterious to cells: the first is the use of high cryoprotectant concentrations, which may have toxic effects on cells, and the second is the use of high cooling and heating rates, which can be difficult to achieve when using large volumes of solution (Rubinsky, 2003;Xin et al, 2017).…”

Currently, aquaculture has been growing due to factors such as increased fish consumption and production, population growth, higher family income and urbanization (Food and Agriculture Organization of the United Nations (FAO), 2019). Therefore, studies that focus on investigating the reproductive biology of fish have been intensified to develop species conservation and genetic improvement programmes (Denniston, Michelet, & Godke, 2000), as well as to enable an increase in aquaculture production and reduce pressure on natural stocks. Thus, species belonging to genus Prochilodus, like Prochilodus brevis, a rheophilic species native to Northeast Brazil, have shown increasing potential for use in Brazilian aquaculture (Peixe Br, 2019) to meet the great demand for fish, as they are among the most important species in both commercial and subsistence continental

“…The need for standardized approaches is recognized in some publications, but not dealt with beyond research scale (e.g., Asturiano et al 2017). Many of these reviews also focus on direct comparisons of protocol details (e.g., extender and cryoprotectant) and results (e.g., motility, fertility, and cell viability) (e.g., Cabrita et al 2010; Xin et al 2017) despite the tremendous differences in practice, terminology, and reporting that disallow or weaken such comparisons.…”

Addressing Reproducibility in Cryopreservation, and Considerations Necessary for Commercialization and Community Development in Support of Genetic Resources of Aquatic Species

For the past six decades a repeated cycle of developing new cryopreservation protocols or simply reinventing them to counteract a lack of reproducibility has led to hundreds of published studies that have offered little to the establishment of a genetic resources community for aquatic species. This has hampered repository development and inhibited industrial application. Most protocols were developed without standardized approaches, leading to irreproducible studies and questionable or meaningless comparisons. Thus cryopreservation of germplasm in aquatic species would greatly benefit from strategies to facilitate reproducibility. Our objectives were to: (1) identify major sources of irreproducibility across research, small-scale, repository, and commercial-scale development levels, (2) provide recommendations to address reproducibility challenges, and (3) offer suggestions on how researchers can directly influence commercial development and application of cryopreservation research. Sources of irreproducibility include lack of standardized procedural approaches, lack of standardized terminology, and lack of reporting guidelines. To address these challenges, we propose implementation of standard operating procedures (SOP), support of stock centers and internet content for development of training programs, and strengthening of the role of scientific journals and reviewers in reducing the frequency of irreproducible outcomes. Reproducibility is the foundation for quality management programs and product reliability, and therefore standardization is necessary to assure efficient transition to commercial-scale application and repository development. Progress can only be possible through community-based approaches focused on coalescence and consensus of disparate groups involved in aquatic species cryopreservation and management of genetic resources.
