[EN] The role of seminal plasma sodium and activation media sodium on sperm motility was examined by selectively removing the element from these two media, in European eel sperm. Sperm size (sperm head area) was also ...
[EN] The biodiversity of marine ecosystems is diverse and a high number of species coexist side by side. However, despite the fact that most of these species share a common fertilization strategy, a high variability in ...

[EN] This study evaluates the effects of temperature on hCG-induced spermatogenesis in European eel (Anguilla anguilla), subjected to three thermal regimes: T10: 10 degrees C (first 4 weeks), 15 degrees C (next 3 weeks) ...
[EN] Wild female European eels were matured with CPE (carp pituitary extract) under three thermal regimes, two of
which were variable (T10–15 and T15–18, moving from 10 to 15 °C and from 15 to 18 °C, respectively) and ...
[EN] Estradiol (E-2) can bind to nuclear estrogen receptors (ESR) or membrane estrogen receptors (GPER). While mammals possess two nuclear ESRs and one membrane GPER, the European eel, like most other teleosts, has three ...
[EN] This research investigated the regulation of aromatase and
androgen receptor gene expression in the brain–pituitary–
