Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Redox‐Associated Renal and Male Reproductive Alterations Following Dexamethasone Exposure in Male Rats: Histopathological and Spermatological Evaluations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Dexamethasone (DEX) is widely used in clinical practice, although it may also cause oxidative stress–related damage in different tissues, including the kidney and male reproductive system. This study investigated DEX‐induced renal and reproductive injury in rats and evaluated the modulatory effect of reduced glutathione on DEX‐associated redox

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.

Potential Neuroendocrine Disruption by Benzodiazepines and Its Impact on Male Fertility

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neuroactive substances have emerged as potent endocrine disruptors affecting male reproductive health through central and peripheral mechanisms. Among these, benzodiazepines, which are widely used for the management of anxiety, insomnia, epilepsy, and neuromuscular disorders, are known as GABA A (gamma‐aminobutyric acid type A) receptor ...

Monitoring Changes in Sperm Concentration and Quality Help Improve Captive Breeding Outcomes of the Endangered Amphibian Rawlinsonia littlejohni

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are among the most threatened taxonomic groups, with many species experiencing rapid declines that have resulted in small, isolated populations vulnerable to inbreeding depression and reduced fertility. One major outcome of inbreeding is lowered fecundity, often linked to morphological changes in gametes.

Sperm Motility and Morphology after Preparation Using the Percoll Gradient Method Compared with the IxaPrep Gradient Method

Siriraj Medical Journal, 2003
In order to compare the Percell gradient and IxaPrep gradient methods, the percentage of progressively motile sperm and the percentage of sperm with normal morphology were examined. Thirty five normal semen sample were collected from the male partners of
