Question Answer
Major constituents of the Endocrine system female ovaries, male testes, and the adrenal, thyroid, and pituitary glands
sex steroids androgens (masculinizing) and estrogens (feminizing)
estrogen resembling contaminants PCBs and Bisphenol-A; cause estrogen like response/block natural estrogen
Effects of Metals on Reproduction of Fish Deleterious effects on reproductive gland growth, hormone concentration, sex expression, oogenesis + lipid content in ooplasm, fertilization success, and sperm motility
Effects of Metals on Other Taxa Polychaetes + corals: Change in #no of eggs fertilized → toxicity to sperm and eggs Echinoderms: no effects on sperm motility
Effects of Metals on Crustaceans Deleterious effects on reproductive glands, egg production and yolk content, hatching rates, maturation, growth, and molting
Effects of Metals on Mollusks Deleterious effects on fertility (imposex + sterilization), levels of sex free/esterified hormones, gamete maturation/expression, GSI, sexual maturation, and sperm motility
Effects of Organics on Crustaceans deleterious effects on gonadal development, hatching success, offspring mortality, development, and mating success
Effects of Organics on Fish deleterious effects on hormone levels, gonad development/growth, sperm count, egg/oocyte development, migratory/reproductive behavior, offspring survival, hatching rate/fecundity, and offspring development
Effects of Organics on Mollusks deleterious effects on gonad development/function, gamete development/maturation, gamete production, and offspring development
Effects of Organics on Other Taxa deleterious effects on reproductive success, sex hormone levels, thyroid steroids, larvae release, fertilization, and offspring development/survival
Effects of Climate Change on Fish higher susceptibility to other pollutants, alteration in reproductive investment/habits
Effects of Climate Change/Acidification on Crustaceans little deleterious effect (some hormesis), but at higher levels -> delayed hatching, reduced hatching success, and decreased offspring development/growth
Effects of Acidification on Other Taxa Corals - reduced sperm count + motility Echinoderms - no effects
Effects of hypoxia on fish reduced gonad growth
Effects of Hypoxia on Crustaceans deleterious effects on offspring survival, fertility; resistant species in estuaries -> only slower brood production
Effects of CECs on Fish deleterious effects on sex hormone production, fertilization, gonad development, and spawning success
CuO vs CuCl2 effects on Mollusk reproduction nano-CuO had more deleterious effects on reproduction than CuCl2
Effects of Polluted Sites on Fish deleterious effects on gonadal development, hormone levels, reproductive behavior, egg production/development, fertilization + fecundity, offspring survival, and sexual maturation
Effects of Polluted Sites on Crustaceans deleterious effects on sex expression/hormone levels, egg development/survival, body size, and offspring production
Effects of Polluted Sites on Mollusks deleterious effects on spawning rate/period, gametogenesis, oocyte resorption, sex expression, fertilization, offspring survival, and populations of reproductive individuals
Effects of polluted sites on Other taxa Corals: though hormone levels were altered by steroid pollution, no effects on reproductive success were observed
Overall Effects on Fish Deleterious effects on gonad development/growth, hormone concentration, sex expression, oogenesis + lipid content in ooplasm, fertilization success, sperm count and motility , migratory/reproductive behavior, offspring survival, hatching rate/fecundity, spawning success, susceptibility to other pollutants, and offspring development
Overall Effects on Crustaceans Deleterious effects on gonadal development/growth, sex expression, hormone levels, fertility, egg production and yolk content, egg survival, hatching rates/success, offspring mortality/development, body size, sexual maturation, and mating success
Overall Effects on Mollusks Deleterious effects on fertility (imposex + sterilization), sex expression, levels of free/esterified sex hormones, gamete development/maturation/expression, oocyte resorption, GSI, sexual maturation, sperm motility, fertilization, gonad development/function, spawning rate/period, offspring development/survival, and populations of reproductive individuals
Overall Effects on Other Taxa polychaetes: Change in #no of eggs fertilized (toxicity to sperm and eggs); corals: Change in #no of eggs fertilized (toxicity to sperm and eggs), fewer breeding colony populations, lower ovary count, premature ejection of larvae, abnormal larval behavior, reduced growth, reduced gonad size, decreased sperm count/motility, Mammals: premature birth, decreased reproductive success, hormone levels,
