Male age: negative impact on sperm DNA fragmentation

Aging, 2019
The main goal of semen processing in Assisted Reproductive Techniques (ART) is to select sperm with good viability and, at the same time, remove Reactive Oxygen Species (ROS) sources (such as leukocytes) and reduce the percentage of morphologically abnormal sperm for fertility treatment.

Leptin induced changes in sperm parameters in Sprague-Dawley rats: role of oxidative stress and its prevention by melatonin / Fayez A. M. Almabhouh [PDF]

, 2016
Exogenous leptin administration has been shown to adversely effect sperm count and sperm morphology in normal adult rats. It is however unknown if it affects sperm DNA integrity and increases apoptosis of sperm and testicular tissue cells.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

Environmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.
