Summary: The study compares a chemically-defined, soy-based medium (SOY) to a commercial egg yolk-based medium (TEY) for sperm cryopreservation in four small cat species. There were no differences in post-thaw traits between the treatments for all four species, suggesting that SOY may be a preferable alternative to TEY for sperm cryopreservation in these felid species.

Summary: This study found that Nobiletin (NOB) can promote the cryosurvival and embryo development of porcine sperm after in vitro fertilization (IVF). The addition of NOB improves sperm motility, acrosome integrity, viability, and mitochondrial membrane potential, reduces lipid peroxidation, and increases cleavage and blastocyst formation rates. Furthermore, NOB treatment upregulates the expression of genes related to pluripotency and cell differentiation in the resulting embryos.

Summary: Catfish farming accounts for 75% of total U.S. finfish aquaculture production, with the channel catfish female x blue catfish male hybrid being the major contributor. The current hatchery technology for producing hybrids is labor-intensive and requires the sacrifice of males. This study aims to optimize the use of available sperm cells and evaluate the health and development of offspring using fresh and cryopreserved sperm.

Summary: Injecting gonadotropin-releasing hormone agonist to induce ovulation in cultured female Senegalese sole, and collecting sperm from cultured males for in vitro fertilization can improve fertilization success rate. The viability of unfertilized eggs stored at room temperature gradually decreases, and faster fertilization results in higher egg viability.

Summary: The expression of life-history traits in fish is influenced by both current and past environmental conditions. This study investigates the effects of carry-over from larval traits and environmental conditions on the life-history traits of European seabass using otolith microstructure analysis. The results show that larval traits have a minor impact compared to the nursery environment on post-settlement traits.

Summary: Studies on the CRISP protein family in mammalian fertilization have provided insights into their essential roles in gamete interaction and male fertility. Knockout experiments with different CRISP genes revealed their involvement in both gamete interaction and subsequent processes such as sperm transport and early embryo development within the female reproductive tract.

Summary: In vitro oocyte maturation (IVM) has been implemented worldwide, but it is not widely adopted in current in vitro fertilization (IVF) due to the lack of synchronization in protocols and definition criteria, resulting in difficulty in collecting proper outcome data and understanding the exact procedure. This review aims to consolidate the current clinical practice of IVM and explore its theoretical basis, as well as discuss potential future uses and the importance of collaboration among IVM centers for better clinical data collection and safety purposes.

Summary: Transgender women undergoing semen cryopreservation have poor sperm quality compared to the general population, with further impairments in specimens collected after discontinuation of gender-affirming hormone treatments. Post-thawing sperm total motile count, motility, and overall sperm survival are also reduced in transgender women.

Summary: The study compared the use of fresh and cryogenically frozen lumpfish sperm for fertilization, with fresh sperm resulting in higher fertilization and survival rates for eggs, although there was no significant difference in the weight of the larvae.

Summary: The study utilized the pseudogenization of the AMEL gene as a molecular dating tool to estimate that the loss of dentition in the family Bufonidae occurred approximately 46-60 million years ago. The inactivation of AMEL in modern bufonids and the high sequence identity among AMEL pseudogenes in the family suggest a correlation between genomic mutation patterns and the rise of true toads within the Bufonidae lineage.

Summary: This study investigates the long-term physiological effects of early hypoxia exposure in the economically significant species Pacific abalone, revealing that juvenile abalones exposed to hypoxia at early development stages exhibit higher hypoxia tolerance but slower weight growth. These phenotypic effects are driven by strong selection of genes involved in signal transduction, autophagy, apoptosis, and hormone regulation, as well as the regulation of long non-coding RNA.

Summary: This study characterized the sublethal effects of four environmental toxic compounds on Rhinella arenarum tadpoles in two experimental pollution scenarios. Results showed that these harmful substances can cause morphological abnormalities, decreased thyroid levels, inhibited AChE activity, and developmental delay in tadpoles.

Summary: Fertilization is a crucial process in sexual reproduction, but the molecular mechanisms behind it are still unclear. A study on zebrafish reveals that Spaca6, a conserved protein, is essential for sperm-egg binding and fusion. The research also uncovers a previously unknown dependence of Dcst2 expression on Spaca6 in sperm.

Summary: This study explored the effects of aging on sperm quality in the endangered Mississippi gopher frog, with results showing that older males had longer sperm while younger males had more atypical sperm. There were no significant differences in sperm quality based on induction hormones or source populations used at different institutions. This information is valuable for captive breeding programs, indicating that older males may have better sperm quality for fertilization success.

Summary: Zoos and natural history museums are collections-based institutions that play important roles in biodiversity research and education. Despite their overlapping missions, formal partnerships between these institutions are rare. By strengthening the dialogue between zoos and museums, a more comprehensive research dataset could be achieved.

Summary: Ecoimmunology helps us understand immunological processes by considering external factors such as thermal microenvironment. This study examined innate immunity in two species of zoo-housed tortoises and found that both species demonstrated immunocompetence against all bacterial challenges, but only bactericidal ability against Escherichia coli varied over months. There were differences in optimal bacterial killing assay serum dilutions, blood glucose levels, and fecal corticosterone concentrations between the two species. The study also showed that the thermal microenvironment influenced the tortoises' bactericidal ability against E. coli.

Summary: This study investigates the hatching of a tree frog with terrestrial eggs in response to flooding conditions. The findings suggest that flooding-induced hatching is important for the survival of the frog, and the ability to hatch early improves survival rates. These results highlight the significance of hatching plasticity in amphibians with terrestrial eggs.

Summary: This study focused on the post-release growth and survivorship of amphibian offspring produced from frozen/thawed sperm for conservation translocation. It found that these offspring were smaller than natural counterparts, and early-life growth differences could lead to substantial differences in final life fecundity and population trends. The study emphasizes the need for more attention to the differences between captive-bred and cryo-derived individuals compared to natural counterparts, as well as the development of viable cryopreservation technologies for conservation translocation at the population level.
