The goal of this work was to correlate oxidative stress caused by reactive oxygen species (ROS) and DNA damage with classic semen parameters in spermatozoa and seminal plasma of fertile and subfertile stallions. Oxidation was measured in both lipids and proteins, using the thiobarbituric acid reactive species (TBARS) assay and the DNPH carbonyl groups assay, respectively. Sperm DNA damage was m...

Background: The incidence of anti-chlamydia trachomatis immunoglobulins in serninal plasma and serum of infertile men was detected by microimmuno fluorscence (MIF) test .The main objective was to determine and compare the performance of seminal plasma and serum in the diagnosis of chlamydia trachomatis genital infection in Iraqi infertile men. Patients and Method: Seminal fluid and blood sample...

Background: Plasma membrane of the spermatozoa interacts with and is altered by abundant seminal PDC-109 present in their immediate milieu in vivo with damaging effect in a time- and concentration- dependent manner. Therefore we hypothesized that sequestration of detrimental protein from ejaculates would be beneficial for cryopreservation of sperm cells. To this aim we evaluated the effect of s...

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...

From the experimental results of three independent methods: (1) indirect immunofluorescence employing monospecific anti-seminalplasmin-IgGs, (2) cell-free translation of poly(A)+ RNA from seminal vesicle and testicular tissue, as well as (3) Northern analysis of poly(A)+ RNA of the latter tissues with a synthetic seminalplasmin-specific antisense DNA probe, it is concluded that the biosynthesis...
