TL;DR: Most plasticizers appear to act by interfering with the functioning of various hormone systems, but some phthalates have wider pathways of disruption, and given the sensitivity of some invertebrates, effects assessments are warranted in other invertebrate phyla.

TL;DR: Despite many years of research, sperm quality assessment methods continue to provide imprecise data about fertility; here it is suggested that this may be a consequence of using tests that focus on the spermatozoa that would normally be unable to fertilise under natural conditions.

TL;DR: The wide-ranging physiological differences seen between dominant and subordinate zebrafish as a consequence of their social status suggest negative health impacts for subordinates after prolonged durations in those hierarchies.

TL;DR: Contrary to the findings demonstrating mechanisms that promote MH complex heterozygosity, the results showed that males won significantly greater relative fertilization success when competing for eggs from genetically similar females at the MH class I.

TL;DR: It was demonstrated that EE(2) exposure compromised the reproductive health of breeding zebrafish at environmentally relevant concentrations and the molecular mechanisms mediating some of these effects were identified and included those impacting processes central to gametogenesis in both males and females.
