[PMID: 37229958 DOI: 10.1016/j.theriogenology.2023.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/04/2023] [Accepted: 05/04/2023] [Indexed: 05/27/2023]
Abstract
Ovarian fluid is essential for successful fertilization by maintaining the viability, motility, and velocity of sperm. The organic compounds and inorganic ions in ovarian fluid significantly influence spermatozoa's motility, velocity, and longevity. However, the effect of ovarian fluid on sperm performance is limited in teleost fish. In this study, the effect of ovarian fluid on sperm performance and its components in external fertilization species (Scophthalmus maximus, turbot) and internal fertilization species (Sebastes schlegelii, black rockfish) was investigated using computer-assisted sperm analysis, high-performance liquid chromatography, and metabolome analysis. The ovarian fluid had a distinct and species-specific effect on both species. In the black rockfish, the ovarian fluid from turbot significantly increased sperm motility (74.07% ± 4.09%), as well as VCL (45 ± 1.67 μm/s), VAP (40.17 ± 1.6 μm/s), and VSL (36.67 ± 1.86 μm/s), and longevity (352 ± 11.31 min) (P < 0.05). In the turbot, only the longevity (71.33 ± 5.69 min) and fertilization rate (65.27% ± 11.59%) showed significantly improvement (P < 0.05). The ovarian fluid was rich in organic compounds, suggesting enrichment in the glycolysis/gluconeogenesis pathways. The results suggest that glycometabolism plays a crucial role in improving sperm performance in teleost with internal fertilization. Thus, incorporating ovarian fluid into the sperm activation medium can enhance artificial fertilization in fish breeding.

Abstract
Sexually selected traits can be costly to produce and maintain. The amount of resources available to an individual is therefore expected to influence investment in costly sexual traits. While resource-dependent expression of sexually selected traits has traditionally been examined in males, resource limitation can also influence how sexual selection operates in females. Female reproductive fluids are thought to be costly to produce and may play an important role in shaping the outcome of postcopulatory sexual selection by influencing sperm performance. However, we know surprisingly little about whether and how female reproductive fluids are influenced by resource limitation. Here, we examine if resource restriction influences female reproductive fluid-sperm interactive effects in the pygmy halfbeak (Dermogenys collettei), a small internally fertilizing freshwater fish where females store sperm. After experimentally altering female diets (high vs. restricted diets), we compared how female reproductive fluids influence two key metrics of sperm quality: sperm viability and velocity. While female reproductive fluids enhanced sperm viability and velocity, we found no evidence that female diet influenced the interactive effect between female reproductive fluids and sperm viability or velocity. Our findings build on the growing evidence that female reproductive fluids influence sperm performance and call for further attention to be devoted to understanding how resource quantity and quality influence how female reproductive fluids affect sperm performance.

Animals (Basel) 2023; 13:ani13040572. [PMID: 36830358 PMCID: PMC9951666 DOI: 10.3390/ani13040572] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 01/27/2023] [Accepted: 02/03/2023] [Indexed: 02/10/2023] Open
Abstract
The purpose of this study was to compare four activation solutions (AS)-Woynarovich, Lahnsteiner, Kucharczyk, and Perchec-with the addition of 0.5% bovine serum albumin (BSA) for ide (Leuciscus idus) sperm activation and analysis with a CASA system. It was found that ide sperm can be activated using each AS within a pH range of 7.4-9.0 and an osmolality range of 160-200 mOsm kg-1. The effect of Woynarovich and Perchec solutions supplemented with BSA and casein at concentrations of 0.25, 0.5, 1.0, and 2.0% were also analyzed during the experiment. These two AS without protein supplementation (pure solutions) were the controls. Woynarovich and Perchec solutions supplemented with the minimum BSA concentration (i.e., 0.25%) significantly improved sperm motility (89.05% and 86.63%, respectively) compared to the controls (20.39 and 28.48%, respectively). Similar increases were also noted in progressively motile sperm (PRG, %), the curvilinear velocity of sperm (VCL, µm s-1), and the amplitude of lateral head displacement (ALH, µm). A similar trend in CASA parameters was also noted when casein was added to Woynarovich and Perchec solutions at a concentration of 0.25%. We concluded that 0.25% doses of each of the proteins were sufficient to prevent sperm adhesion to glass slides, and they can be used in research on ide sperm motility measurements.

Abstract
In a large majority of animal species, the only contribution of males to the next generation has been assumed to be their genes (sperm). However, along with sperm, seminal plasma contains a wide array of extracellular factors that have many important functions in reproduction. Yet, the potential intergenerational effects of these factors are virtually unknown. We investigated these effects in European whitefish (Coregonus lavaretus) by experimentally manipulating the presence and identity of seminal plasma and by fertilizing the eggs of multiple females with the manipulated and unmanipulated semen of several males in a full-factorial breeding design. The presence of both own seminal plasma and foreign seminal plasma inhibited sperm motility, and the removal of own seminal plasma decreased embryo survival. Embryos hatched significantly earlier after both semen manipulations than in control fertilizations; foreign seminal plasma also increased offspring aerobic swimming performance. Given that our experimental design allowed us to control potentially confounding sperm-mediated (sire) effects and maternal effects, our results indicate that seminal plasma may have direct intergenerational consequences for offspring phenotype and performance. This novel source of offspring phenotypic variance may provide new insights into the evolution of polyandry and mechanisms that maintain heritable variation in fitness and associated female mating preferences.

Abstract
In this study, semen seminal plasma contents and the motility of sperm cells were determined in Capoeta trutta via a computer-assisted sperm analysis system. In addition, we evaluated the relationship between semen seminal plasma ions and the velocities of sperm cells. Although the predominant ions were K ( 206.84 ± 20.61 mg L- 1 ) and Na ( 128.06 ± 23.82 mg L- 1 ) in the semen seminal plasma, Ca ( 14.05 ± 4.13 mg L- 1 ) and Mg ( 3.35 ± 0.44 mg L- 1 ) were not predominate according to our results. However, partially strong relationships between the curvilinear velocity value (VCL) and K (R 2 = 0.67 ; p < 0.05 ) were found, while it was moderate with Mg (R 2 = 0.48 ; p < 0.05 ). There was a weak relationship with Na (R 2 = 0.17 ; p < 0.05 ) and Ca (R 2 = 0.34 ; p < 0.05 ). In our results, while the trace metals were determined as Zn > Al > B > Li > Cu in semen seminal plasma, they are not correlated with sperm cell velocities. Finally, we hope that the present information on the motility parameters of Capoeta trutta in this paper will eventually help artificial insemination in reproduction practices.

Abstract
Male and female gametes are often embedded in fluids that are produced by gonads and other reproductive tissues. Female reproductive fluids, usually called ovarian fluid (OF), which often constitute a relevant volumetric component of the egg mass, are rich in ions, sugars and proteins, and are involved in several functions, from protecting gametes to facilitating fertilization, and often act as mediators of post-mating sexual selection. Despite their applied and evolutionary importance, we know virtually nothing about the costs of female reproductive fluid production. We investigated the effect of nutritional condition on OF quality by experimentally manipulating the diet of two groups of female guppies (Poecilia reticulata) which were maintained for 20 days either on a restricted diet or had ad libitum access to food. In this species, OF enhances sperm swimming longevity and velocity (a predictor of sperm competition success) and mediates post-copulatory inbreeding avoidance. We found that sperm velocity was significantly lower in the OF of diet-restricted females, indicating that OF quality is dependent on female nutritional condition. Our results demonstrate that OF represents a non-trivial component of female reproductive investment and provides a tool to investigate which OF constituents are involved in modulating OF-sperm interactions and fertilization.

Abstract
Factors such as gamete quality can profoundly affect fertility, but the spawning micro-environment that surrounds the spermatozoa and eggs during gamete contact has largely been neglected. In fishes, understanding these gametic interactions is crucial because each female creates a unique spawning environment by simultaneously expelling her distinct ovarian fluid (OF) along with an egg batch. In turn, OF has been shown to influence spermatozoa performance traits by modifying spermatozoa behaviors and fertilization outcomes. Here, we shed light on these gametic interactions by overviewing literature on OF and how it impacts spermatozoa performance traits. Fish OF is clear or has slight coloration and can constitute ≤10-30% of egg mass. Viscosity of the OF is ∼2- to 3-fold higher than water and its pH ranges 6.2 to 8.8. Osmolality of the OF is lower in freshwater (190-322 mOsmol/kg) than marine species (289-514 mOsmol/kg). Na+ (98.3-213.7 mmol/L) and Cl- (89.8-172.7 mmol/L) are predominant ions in OF, while K+ (1.7-19.3 mmol/L), Mg2+ (0.4-8.1 mmol/L), and Ca2+(0.5-9.7 mmol/L) ions are detected at lower concentrations. Protein levels can be high in OF and exhibit intra- and inter-species variation (54-826 mg/100 mL). Fish OF also contains a series of organic components and substances that enhance and/or attract sperm towards the vicinity of an egg. OF can also differentially impact sperm based on genetic relatedness of mates, male phenotype (i.e. alternative reproductive tactics), or geographic origin. To conclude, when testing further reproductive paradigms, we suggest a shift from classic spermatozoa activation medium (water only) to more natural spawning media, which encompass OF-spermatozoa interactions.
