introduction artificial insemination (ai) has only been used as a supplement to natural mating. ai, when used in conjunction with accurate progeny testing schemes, can substantially increase the rate of genetic progress compared with that of natural service. moreover, the use of ai causes the limitation of the transmitted diseases. cervical insemination with frozen-thawed ram semen has not been...

Background: Oligoasthenospermia (OAS) is a condition characterized by low sperm count associated with low sperm motility. Medical treatment is not known in allopathic system for treatment of oligoasthenospermia. Homeopathic medicine is effective in more than 95% patients. Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology...

a:4:{s:9:"Objective";s:402:"Uric acid (UA) is crucial for sperm metabolism; it protects seminal plasma against oxidative damage. Zinc, too, plays a central role in sperm metabolism. The current study was designed to investigate the role of zinc supplementation on the qualitative and quantitative properties of seminal fluid, in parallel with the UA level and urate pathway enzymes in the semen of...

OBJECTIVE This prospective study was designed to investigate the relationship between lipids levels in both serum and seminal plasma and semen parameters. METHODS 631 subfertile men were enrolled. Their obesity-associated markers were measured, and semen parameters were analyzed. Also, seminal plasma and serum TC, TG, HDL and LDL and serum FFA, FSH, LH, total testosterone (TT), estradiol (E2)...

Understanding the biochemical processes associated with ovum fertilization and knowledge about the structure and function of individual substances participating in these processes is crucial for the development of biotechnological methods to improve reproduction of animals and humans. Among many components of seminal plasma, proteins and peptides play a specific role in regulation of the fertil...

In this study immunoelectrophoretic and double immunodiffusion analyses were used to investigate the antigenic character of zinc-binding proteins (ZnBPs), whereas the indirect immunofluorescence technique was used to identify their origin in boar reproductive tract. The mmunoelectrophoretic analysis of ZnBPs of the seminal plasma resulted in the appearance of three antigenic protein complexes, ...

Total lipid concentration was elevated in the seminal plasma of oligo- and azoospermic men. The total cholesterol content was comparatively more in the seminal plasma of azoospermic men than in that of normo- and oligospermic men. In general, infertility was associated with increased seminal concentrations for most of the neutral lipid classes. However, total phospholipids and most of the phosp...

Variation in the effect of seminal plasma on sperm function and fertility has been hypothesised to be due to differences between males and their seminal plasma composition. The freezing resilience of individual rams (n=17) was investigated to characterise inter-male variation. This was determined by measuring the degree of change in motility induced by cryopreservation (Experiment 1). Experimen...
