Human xylosyltransferase (EC 2.4.2.26, XT) is the initial enzyme involved in the biosynthesis of the glycosaminoglycan chains in proteoglycans. XT activity in body fluids was shown to be an indicator for the actual proteoglycan biosynthesis rate.MethodsXylosyltransferase activity was determined in seminal plasma and serum samples of 50 healthy semen donors, 20 infertile men with oligo-, astheno- or teratozoospermia and men after vasectomy. For identification of the XT secreting glands split ejaculates were analyzed.ResultsXT activity in seminal plasma samples of infertile men was significantly reduced (mean 1.53 mU/l, 90% range 0.95-2.52 mU/l, p<0.05) in comparison to healthy donors (mean 3.21 mU/l, 90% range 1.82-4.65 mU/l). The analysis of the fractionated ejaculates revealed that the highest XT activity was found in portions secreted by the seminal vesicle glands.ConclusionsIn view of the increasing interest for in vitro fertilization, monitoring the seminal plasma XT activity of men with unexplained infertility is proposed to be an advantageous additional biochemical parameter that could be useful for improving the methods producing pregnancy in some couples."xsd:string |
