Cryopreservation is a widely used technique to store spermatozoa for a long time. Some Published articles have identified the cryoprotective effect of nanoparticles on sperm quality after the freeze-thaw process, but others have suggested the opposite results. PubMed, ISI Web of Science, and Scopus were systematically searched in animal studies by ("sperm" OR "spermatozoa") AND ("cryopreservation" OR "cooling storage" OR "freezing" OR "thawing") AND ("nanoparticle (lecithin nanoparticle, selenium nanoparticle, zinc nanoparticle, zinc oxide nanoparticle, nanoliposome, solid lipid nanoparticle (SLN), micelle, hydrogel, nanogel, silica nanoparticle, quantum dot, dendrimer, gold (Au) nanoparticle, silver nanoparticle, nanocomposite and mesoporous)"). Among 154 publications, data on sperm quality were extracted from 11 articles. The meta-analysis results demonstrated that nanoparticles had a positive impact on sperm progressive motility (WMD= 9.72, 95 % CI: 4.70, 14.75, p < 0.0001), total motility (WMD= 6.78, 95 % CI: 0.78, 12.78, p = 0.027), viability (WMD= 14.30, 95 % CI: 9.48, 19.13, p < 0.0001) and plasma membrane integrity (WMD = 13.74, 95 % CI: 8.20, 19.29, p < 0.0001). In conclusion, our results indicated the positive effects of nanoparticles as cryoprotectant agents on post-thawed sperm motility, viability, and membrane integrity.

Polylactic Acid Micro/Nanoplastic Exposure Induces Male Reproductive Toxicity by Disrupting Spermatogenesis and Mitochondrial Dysfunction in Mice.

Although considered an "eco-friendly" biodegradable plastic, polylactic acid (PLA) microplastic (PLA-MP) poses a growing concern for human health, yet its effects on male reproductive function remain underexplored. This study investigated the reproductive toxicity of PLA in male mice and its potential mechanisms. To this end, our in vivo and in vitro experiments demonstrated that after degradation in the digestive system, a significant number of PLA-MP-derived nanoparticles could penetrate the blood-testis barrier (BTB) and localize within the spermatogenic microenvironment.

More than 90% of spermatozoa of boars in pork producing countries is stored in liquid at 17 °C; however, the quality of these spermatozoa is affected by bacterial breeding and oxidative damage. This study analyzed sperm quality and sperm capacitation after storage to study the effects of the effects of ZnO nanoparticles (ZnO NPs) supplementation on seminal plasma (SP)-free sperm preservation. We investigated the effects of adding 20, 50, 100 and 200 μg/mL of ZnO NPs to a seminal free boar sperm diluent over a 7-day period at 17 °C to assess the changes in non-capacitated/capacitated sperm quality parameters, antioxidant capacity, ATP content and extent of protein tyrosine phosphorylation.

Perfluorooctanoic acid (PFOA) and nano-titanium dioxide (nano-TiO₂) are widely used in industrial applications such as manufacturing and textiles, and can be released into the environment, causing toxicity to marine organisms. To study the effects of these pollutants on the gonadal development, we exposed the males of Mytilus coruscus to varying PFOA concentrations (2 and 200 μg/L) alone or combined with nano-TiO (0.1 mg/L, size: 25 nm) for 14 days.

Doxorubicin (DOX) is a powerful antineoplastic FDA-approved anthracycline-derived antibiotic and is considered as the most suitable intervention for solid tumors and hematological cancers therapy. However, its therapeutic application is highly limited due to acute and chronic renal, hematological and testicular toxicity. Oxidative stress, lipid peroxidation and apoptosis in germ cells as well as low sperm count, motility and disturbing steroidogenesis are the principal machineries of DOX-induced testicular toxicity.

Magnetic microrobots are significant platforms for targeted drug delivery, among which sperm-inspired types have attracted much attention due to their flexible undulation. However, mass production of sperm-like soft magnetic microrobots with high-speed propulsion is still challenging due to the need of more reasonable structure design and facile fabrication. Herein, a novel strategy is proposed for large-scale preparation of microalgae-based soft microrobots with a fully magnetic head-to-tail structure, called AlgaeSperm with robust propulsion and chemo-photothermal performance.
