Females frequently mate with several males, whose sperm then compete to fertilize
available ova. Sperm competition represents a potent selective force that is expected to …

This review summarizes current knowledge on ultraviolet radiation (UVR)-induced cellular
and molecular damage in marine ectotherms (invertebrates and fish). UVR impairs sperm …

Hypoxia has a profound effect on fish reproduction and development. Behavioral studies
revealed that hypoxia can affect courtship behaviors, mate choice, and reproductive efforts …

Abstract Silver nanoparticles (Ag-NPs) are increasingly used in a wide range of consumer
products and such an extensive use raises questions about their safety and environmental …

As a result of endocrine disruptor studies, there are numerous examples of male related
