Background: The aim of this study was to evaluate seminal plasma coenzyme Q10 levels and oxidative stress in patients with different types of male infertility. Materials and Methods: The study took place in the Department of Chemistry and Biochemistry, College of Medicine, Al-Nahrain University- Baghdad-Iraq from the period of November 2004 till July 2006. Sixty patients with male infertility w...

semen hyperviscosity (shv) is one of the factors involved in deficiency in sperm function. this research aimed to evaluate seminal plasma total antioxidant capacity (tac) and malondialdehyde (mda) levels in infertile patients with hyperviscous and non-hyperviscous semen samples to understand whether hyperviscous semen is associated with oxidative damage in infertile subjects. in this cross sect...

Bovine Leukemia ProVirus: Evidence of Presence of Part of Gag Gene in Seminal Plasma of Naturally Infected Bulls It is of critical importance to understand the modalities of BLV presence in semen, especially with regard to artificial insemination (AI). Presence of bovine leukemia provirus was demonstrated in fresh and frozen semen samples by researchers. In this study paired blood and semen sam...

background: there is growing evidence that damage to spermatozoa by reactive oxygen species (ros) play a key role in male infertility. objective: the aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (tac) and activities of catalase and superoxide dismutase (sod) in men with asthenozoospermia, asthenoteratozoospermia and olig...

Background: Zinc in human semen seems to play an important role in the physiology of spermatozoa. Zinc deficiency leads to gonadal dysfunction, decreases testicular weight, and causes shrinkage of seminiferous tubules. The adult human body contains 1-3 g of zinc, about 0.1% of which is replenished daily. Excessively high amounts of zinc has been reported in human seminal plasma by many authors,...

Some biological aspects of semen were investigated in the Persian sturgeon, Acipenser persicus, by determination of seminal plasma indices (ionic composition and osmolality), sperm density and their relationships with sperm motility. The osmolality of seminal plasma ranged from 42.00 to 111.00 mOsmol Kg-1. The concentrations of Sodium (Na+), Potassium (K+), Chloride (Cl-), Calcium (Ca2+) and Ma...

background: leptin is a polypeptide hormone secreted by white adipose tissue in proportion to body energy. although the participation of leptin in female reproduction is well established any role in male reproductive function is at best tenuous. objective: the objective of this study was to compare the leptin concentration in human seminal plasma and then the relationships between seminal lepti...

results seminal plasma tac level in normospermic men was significantly higher than asthenoteratospermic men (p < 0.001) and oligasthenoteratospermic men (p < 0.001) and had posetive correlation with sperm count, motility and morphology. in contrast mda levels in normospermic men were significantly lower than in asthenoteratospermic men (p = 0.049) and oligoasthenoteratospermic men (p = 0.001) a...

The aim of this study was to investigate the comparison between some seminal plasma parameters and age of the bull. Concentrations of various biochemical parameters like fructose, glucose, total proteins, albumin and inorganic ions including Na, K and Cl ions of seminal plasma of breeding Sahiwal bulls of different ageswere assessed. Methods: 40Sahiwal bullsdivided into 4 age groups.Semen (2ml ...
