background: prostate specific antigen (psa) is an important laboratory marker for diagnosis of prostatic cancer. thus, development of diagnostic tools specific for psa plays an important role in screening, monitoring and early diagnosis of prostate cancer. in this paper, the production and characterization of a panel of murine monoclonal antibodies (mabs) against psa have been presented.  metho...

BACKGROUND Zinc in human seminal plasma is divided into three types of ligands which are high (HMW), intermediate (IMW), and low molecular weight ligands (LMW). The present study was aimed to study the effect of Zn supplementation on the quantitative and qualitative characteristics of semen along with Zinc Binding Protein levels in the seminal plasma in asthenozoospermic patients. METHODS Sem...

Asian elephants (Elephas maximus) have highly variable ejaculate quality within individuals, greatly reducing the efficacy of artificial insemination and making it difficult to devise a sperm cryopreservation protocol for this endangered species. Because seminal plasma influences sperm function and physiology, including sperm motility, the objectives of this study were to characterize the chemi...

The presence of various cytokines, namely the tumor necrosis factor (TNF-alpha), interferon (IFN-gamma), and interleukins (IL-1 beta and IL-6), was investigated in seminal plasma of fertile, infertile, and immunoinfertile men using specific immunoradiometric assays. TNF-alpha and IL-1 beta were not detected. IFN-gamma was detected, but the differences between the levels of fertile and infertile...

BACKGROUND To determine any correlation between infertility and semen quality with concentrations of L-carnitine in human seminal plasma. METHODS This case-control study performed in Fatemieh Hospital in Hamadan, Iran. Seminal plasma of 72 infertile men and 80 men with proved fertility as a control group was investigated and L-carnitine level was determined using UV enzymatic test at 340 nm. ...

The profile of the zinc ligand high molecular weight proteins was investigated in the seminal plasma of 55 normozoospermic subjects by size exclusion high performance liquid chromatography (HPLC). The proteins were recovered from Sephadex G-75 gel filtration of seminal plasma in three zinc-containing fractions which were then submitted to HPLC analysis. The results were, that in all the samples...

To investigate the impact of calcium, magnesium, zinc, and copper in blood and seminal plasma on semen parameters, 107 fertile and 103 subfertile males provided a standardized blood and semen specimen. Total calcium and magnesium concentrations were determined with colorimetric end point assay procedures. Zinc and copper were determined by flame atomic absorption spectrophotometer (AAS). Semen ...

Human seminal plasma has potent anti-inflammatory properties which are thought to confer a survival advantage to the spermatozoa within the hostile female genital tract. In contrast, a profound pro-inflammatory leukocytosis has been observed post-coitus in animals and humans. Whether components of seminal plasma are involved in initiating this leukocytic reaction is not known. This study invest...

INTRODUCTION HIV transmission risk is highest during acute HIV infection (AHI). We evaluated HIV RNA in the anogenital compartment in men who have sex with men (MSM) during AHI and compared time to undetectable HIV RNA after three-drug versus five-drug antiretroviral therapy (ART) to understand risk for onward HIV transmission. METHODS MSM with AHI (n=54) had blood, seminal plasma and anal la...

Introduction&Aim of the work: to assess effects smoking on TAC and NO levels in seminal plasma patients who suffer from oligoasthenozoospermia.
