The spermatozoa of most fish species are immotile in the testis and seminal plasma.
Therefore, motility is induced after the spermatozoa are released into the aqueous …

Fish spermatozoa acquire potential for motility in the sperm duct where they are immotile.
Osmolality of the seminal plasma is a key factor to maintain spermatozoa in the quiescent …

As the chemical environment of semen can have a profound effect on sperm quality, we
examined the effect of pH on the motility, viability and capacitation of human sperm. The …

Motility is a key factor in function of the spermatozoon and determines semen quality and
fertilizing capacity. Effective motility occurs when sperm is diluted in a swimming solution …

The relationships between the compositions of ovarian, seminal fluids and sperm function
are not well known in teleostean fish species. The objective of the present study was to …

Zinc as an essential micronutrient in organisms and natural environments plays an important
role in many biological activities. In this study, the effects of feeding with different sources of …

Northern pike (Esox lucius L.) spermatozoa are uniflagellated cells differentiated into a head
without acrosome, a midpiece and a flagellar tail region flanked by a fin structure. Total …

The objectives of the present study were to characterize sperm volume and density, seminal
plasma indices (ionic contents and osmolality) and to study the effects of dilution ratio, ions …

The giant grouper, Epinephelus lanceolatus, is one of the most valuable tropical commercial
fishes. The asynchronous maturity periods between males and females hampers breeding …

In the present review, sperm morphology, acrosome reaction, motility, short-term storage
and cryopreservation are summarized and discussed in sturgeon (Chondrostei …
