This study was aimed at investigating the use of seminal plasma protein concentration to predict fertility and hatchability in the domestic fowl. Forty cocks with acceptable sperm motility and morphology were used and the seminal plasma protein concentration determined by the Biuret method. The result revealed a negative significant correlation between the seminal plasma protein concentration w...

Serum amyloid P component (SAP) belongs to the pentraxin family of proteins. SAP is evolutionary conserved, and involved in amyloidosis, innate immunity, inflammation, and apoptosis. We have previously described SAP in the male reproductive tract, where it occurs in seminal fluid, on spermatozoa, and in epididymal, seminal vesicle, and prostate tissue. In the present investigation, our aim was ...

Dietetic habits revealed significant effect on seminal plasma vitamin B12 levels. The mean values for seminal plasma vitamin B12 activity in lactovegetarians from normozoospermic, oligozoospermic and azoospermic groups are significantly lower than the corresponding mean values observed in the nonvegetarian subjects. The mean vitamin B12 content of seminal plasma in azoospermic group was distinc...

The oxygen uptake of bovine endometrium was less when perfused with seminal plasma than when perfused with Krebs-Ringer phosphate buffer solution. Dialysing the seminal plasma against Krebs\x=req-\ Ringer phosphate buffer solution did not alter the depressant action of the seminal plasma. The depressant substance was shown to be partially heat labile. Variable mineral concentrations were not re...

BACKGROUND The objective of the present study was to isolate and purify the protein fraction(s) of llama seminal plasma responsible for the ovulation-inducing effect of the ejaculate. METHODS Semen collected from male llamas by artificial vagina was centrifuged and the seminal plasma was harvested and stored frozen. Seminal plasma was thawed and loaded onto a Type 1 macro-prep ceramic hydroxy...

conclusions our results show that oxidative stress could play an important role in male infertility as well as in sperm motility and sperm morphology. patients and methods this case control study was conducted using 35 men with idiopathic infertility and 34 men with proven fertility. seminal plasma tac and mda were measured by ferric reducing ability of plasma (frap) and thiobarbituric acid (tb...

The objective of this study was to investigate aspartate-amino-transferase (AST), γ-glutamyl-transferase(GGT), alkaline phosphatase (ALP), lactate-dehydrogenase (LDH) and acid phosphatase (AcP) activities andsemen parameters (volume, pH, concentration, total sperm number (TSN), progressive motility, dead sperm,total morphological defect (TMD) and hypo-osmotic swelling test (HOST)) in seminal pl...

Seminal plasma is comprised of the extracellular sperm milieu from spermatogenesis in the testes, through to maturation in the epididymis, as well as secretions from the accessory sex glands. Consisting primarily of proteins, this substance has a multitude of functions in mammalian reproduction. Seminal plasma influences sperm physiology, success of semen freezing, migration of spermatozoa thro...
