Glycoprotein fucosylation is increased in seminal plasma of subfertile men.
Fucose, the monosaccharide frequent in N- and O-glycans, is a part of Lewis-type antigens that are known to mediate direct sperm binding to the zona pellucida. Such interaction was found to be inhibited in vitroby fucose-containing oligo- and polysaccharides, as well as neoglycoproteins. The objective of this study was to screen seminal plasma proteins of infertile/subfertile men for the conten...
متن کاملImpact of DNA Damage on the Frequency of Sperm Chromosomal Aneuploidy in Normal and Subfertile Men
Background: Various frequencies of sperm aneuploidy are reported in sperms of subfertile patients compared to normal individuals. Moreover, sperm DNA damage is shown to be associated with male infertility. In this study, the rate of DNA damage and frequencies of aneuploidy in sperms of subfertile patients was investigated. Methods: Semen samples were obtained from healthy normal and subfertile ...
متن کاملCorrelation between Seminal Fluid Analysis and Levels of Gonadotropins in Serum and Seminal Plasma of Normozoospermic Men and Infertile Patients
Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...
متن کاملRelationship between Lipids Levels of Serum and Seminal Plasma and Semen Parameters in 631 Chinese Subfertile Men.
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)...
متن کاملRelationship between seminal plasma zinc concentration and spermatozoa-zona pellucida binding and the ZP-induced acrosome reaction in subfertile men.
The aim of this study was to determine the relationship between seminal zinc concentration and spermatozoa-zona pellucida (ZP) binding and the ZP-induced acrosome reaction (ZPIAR) in subfertile men. Semen analyses and seminal zinc concentration assessments were carried out according to the World Health Organization manual for 458 subfertile men. A spermatozoa-ZP interaction test was carried out...
