Description
Yves Moreira Ribeiro and co-authors present a 2026 journal article on how the natural estrogen estrone, a pollutant in farm runoff and sewage, harms fish reproduction. Zebrafish were exposed for forty-nine days to three estrone levels found in real surface waters, from twenty to two thousand nanograms per liter. The team then examined ovaries, hormone levels, and spawning success.
Exposure reshaped the ovary: more immature egg cells and withered follicles, more inflammation, and fewer support cells. A related hormone and a growth factor signal rose at the lower doses, while a nitrogen stress marker climbed at the higher ones. Egg production fell in every exposed group, and fertilization rates dropped significantly at the two higher doses, even at common environmental levels.
