Seminal Plasma Heparin Binding Proteins Improve Semen Quality by Reducing Oxidative Stress during Cryopreservation of Cattle Bull Semen
Seminal Plasma Heparin Binding Protein [HBP] Cryopreservation Function Tests Sperm Cattle Bulls
2016/11/10
Heparin binding proteins (HBPs) are produced by accessory glands. These are secreted into the seminal fluid, bind to the spermatozoa at the time of ejaculation, favour capacitation, acrosome reaction,...
Comparison of oxidant and antioxidant status of seminal plasma and spermatozoa of several fish species
antioxidant enzymes oxidative stress fish sperm
2015/6/24
Oxidant and antioxidant activity in seminal plasma was compared with that in spermatozoa of teleost (common carp Cyprinus carpio and brook trout Salvelinus fontinalis) and chondrostean (Russian sturge...
Proteolytic and anti-proteolytic activity in the seminal plasma of Eurasian perch (Perca fluviatilis L.) during the spawning period
European perch seminal plasma protease and anti-protease activity
2015/6/9
The aim of this study was to describe possible changes in protease and anti-protease activity in the seminal plasma of European perch (Perca fluviatilis L.) during the spawning time. No significant di...
Relationships between seminal plasma composition and sperm quality parameters of the Salmo trutta macrostigma (Dumeril, 1858) semen: with emphasis on sperm motility
spermatological parameters spermatozoa seminal fluid Salmo trutta macrostigma
2015/6/9
The mineral and organic composition of seminal plasma, physical spermatological parameters and their physiological relationships were investigated in Salmo trutta macrostigma. The seminal plasma conta...
