Summary: The study showed that under simulated transport conditions, the response of boar spermatozoa to agitation stress is influenced by the type of semen extender, time after semen processing and temperature. Some samples experienced reduced sperm motility and viability after shaking during storage, while others were unaffected by agitation-induced loss of quality.

Summary: The optimum storage temperature for liquid-preserved boar semen is between 17 and 25 degrees C to maintain stable sperm quality and energy status. Temperatures below 10 degrees C can cause cold shock and imbalance in available ATP in viable spermatozoa, affecting sperm quality and motility. Further measures are needed to address this issue for hypothermic boar semen preservation below 17 degrees C.

Summary: Sperm sexing is a technique commonly used in the dairy industry to sort sperm cells based on X or Y chromosomes. This study analyzed the characteristics of sexed semen compared to conventional semen and found that the enzymatic activity of GAPDHS was significantly higher in sexed samples. This enzyme plays a significant role in sperm motility and may contribute to enhancing the fertility characteristics of sexed semen.

Summary: Epididymal semen from dogs and cats provides an additional source of gametes for preserving valuable genetics, especially in cases where ejaculation is not possible, castration is necessary, or unexpected death occurs. Understanding the differences between epididymal semen and ejaculated semen is crucial for optimizing cryopreservation and enhancing the applications of assisted reproductive technologies. Factors affecting epididymal semen quality and freezability need to be identified and addressed to improve post-thaw semen quality and ART outcomes.

Summary: The study found that severe clinical disease and the presence of C. pecorum in the semen were associated with significantly higher sperm DNA damage in wild male koalas. Conversely, wild koalas with severe clinical signs but negative for C. pecorum in semen had the highest percentage of morphologically abnormal spermatozoa. In vitro incubation with C. pecorum led to decreased sperm motility and viability over 24 hours.

Summary: This study examined the impact of exposure to multiple heavy metals on bone density using NHANES data, and found that age, body mass index, and urinary concentrations of arsenic, cadmium, and tungsten play significant roles in bone mineral density loss. The classification model based on these factors achieved high accuracy, sensitivity, and specificity in predicting bone density loss, highlighting the importance of arsenic, cadmium, and tungsten in overall bone health.

Summary: Water contaminants in polluted reservoirs can impact the reproductive physiology of Astyanax fasciatus and Hoplias malabaricus males, potentially affecting the endocrine system and physiological adjustments. The biomarkers analyzed in polluted reservoirs show changes in gonadal steroid concentrations, suggesting the presence of endocrine disrupting compounds. Despite physiological changes, both species are able to maintain testicular function for reproduction in highly polluted environments.

Summary: The study investigated the effects of water acidity, temperature, and aluminum on the seminal profile, reproductive parameters, and embryonic development of Astyanax altiparanae. Aluminum exposure decreased fertilization and hatching rates, as well as increased mortality and abnormal larvae. Temperature influenced fertilization time, hatching rate, and morphology. Males exposed to aluminum had lower fertilizing capacity, affecting embryonic development negatively.

Summary: The study conducted in communities directly affected by the disaster revealed high levels of exposure to toxic metals such as aluminum, arsenic, mercury, and nickel. Factors such as community, drinking water, fish and seafood consumption, and smoking habits were found to be associated with metal/metalloid levels in their body. Well and tap water intake were identified as important sources of exposure to aluminum and nickel. The findings represent health risks to the groups living in the areas affected by the tailings dam failure, calling for further studies to evaluate the potential health effects of high exposure to metals and remediation actions from public health Brazilian authorities.
