Penetration of zona-free hamster, bovine and equine oocytes by stallion and bull spermatozoa pretreated with equine follicular fluid, dilauroylphosphatidylcholine or calcium ionophore A23187
(Elsevier B.V., 2001-09-15)
Experiments evaluated the ability of follicular fluid (FF), dilauroylphosphatidylcholine (PC12) and the calcium ionophore A23187 (A23187) to induce capacitation in stallion and bull spermatozoa, determined by the ability ...
Significance of large nuclear vacuoles in human spermatozoa: implications for ICSI
(Reproductive Healthcare Ltd, 2008-07-01)
The aim of this study was to determine the extent of DNA fragmentation and the presence of denatured single-stranded or normal double-stranded DNA in spermatozoa with large nuclear vacuoles (LNV) selected by high magnification. ...
Microtubular defect in equine spermatozoa associated with infertility
(Equine Veterinary Journal Ltd, 1997-11-01)
Proacrosin/acrosin quantification as an indicator of acrosomal integrity in fresh and frozen dog spermatozoa
(ELSEVIER, 2006-06)
The scope of the present study was to evaluate the presence and activation of proacrosin/acrosin as a tool to determine the acrosomal status of fresh and frozen/thawed dog spermatozoa. Monoclonal antibody C5F11, directed ...

Potassium Current in Mature Bovine Spermatozoa
(INFORMA HEALTHCARE, 2008)
Ion channels have been assigned a pivotal importance in various sperm functions and are therefore promising targets for contraceptive development. The lack of data on channel functionality and pharmacology has hampered ...
Cryopreservation of rainbow trout (Oncorhynchus mykiss) spermatozoa using programmable freezing
(Elsevier B.V., 1996)
In an attempt to establish a protocol for the cryopreservation of the spermatozoa of the rainbow trout (Oncorhynchus mykiss), we studied the effect of various cryoprotective agents (CA) in spermatozoa motility and viability, ...

(Sociedad Chilena de Anatomía, 2005)
Spermiogenesis and spermatozoa ultrastructure in Salminus and Brycon, two primitive genera in Characidae (Teleostei : Ostariophysi : Characiformes)
(Wiley-Blackwell, 2006-10-01)
In Salminus, spermiogenesis is cystic and gives origin to a type I aquasperm. Spermatid differentiation is characterized by chromatin condensed into thick fibres, nuclear rotation, nuclear fossa formation, cytoplasmic ...
