“…After their juvenile growth period in continental waters, eels change from yellow eels to prepubertal silver eels, future genitors that will undergo the transoceanic reproductive migration. In captivity, the reproductive cycle is still not closed, and long-term hormonal treatments (fish pituitary extracts for females, and human chorionic gonadotropin, hCG, for males) are required to induce sexual maturation in silver eels (Boëtius and Boëtius, 1967;Pérez et al, 2000;Asturiano et al, 2006;Gallego et al, 2012). This, together with the dramatic reduction in the wild European eel population (ICES, 2012) has increased the interest in deciphering the basic mechanisms controlling the reproduction of this species.…”

“…Former studies have shown that hCG could induce spermatogenesis and sperm maturation in the European eel [4,[19][20][21][22][23]. This treatment promotes a plasma increase of androgen (11-ketotestosterone ) by the Leydig cells [13,15,16,24,25].…”

“…The subjective sperm quality evaluation, widely used in many laboratories working with male gametes, depends on the skill, perception, and training of the researcher who evaluates the sperm samples , Rurangwa et al, 2004Asturiano et al, 2006). In the past few years, several CASA software systems have been developed with the aim of achieving an objective evaluation of sperm quality parameters (Amann and Katz, 2004).…”
