Azoospermia and Sperm Predict Approximately 10-15% of men struggling with interfertility are diagnosed with azoospermia, which means they have no sperm in their semen. Obstructive azoospermia (OA), caused by blockages in the reproductive tract, is responsible for 40% of cases, while the remaining 60% are due to issues with sperm

Sperm DNA Quality It has been determined that high rates of sperm DNA damage are associated with male infertility, decreasing pregnancy rates and increases in pregnancy loss rates. Sperm DNA fragmentation assessment is a valuable test, with high DNA damage being the single best sperm test to predict higher pregnancy

What is sperm aneuploidy? Typically sperm will have either 22 + X or 22 + Y chromosomes. Addition or loss of a single chromosome results in sperm aneuploidy. Sperm aneuploidy occurs due to errors during meiosis. Even perfectly fertile men have sperm with aneuploidy rates between 0.1 – 0.5% per

Verification of male infertility biomarkers in seminal plasma by multiplex selected reaction monitoring assay Seminal plasma is a promising biological fluid to use for noninvasive clinical diagnostics of male reproductive system disorders. To verify a list of prospective male infertility biomarkers, we developed a multiplex selected reaction monitoring assay and

Differential diagnosis of azoospermia with proteomic biomarkers ECM1 and TEX101 quantified in seminal plasma Male fertility problems range from diminished production of sperm, or oligozoospermia, to nonmeasurable levels of sperm in semen, or azoospermia, which is diagnosed in nearly 2% of men in the general population. Testicular biopsy is the

Immunocapture-Selected Reaction Monitoring Screening Facilitates the Development of ELISA for the Measurement of Native TEX101 in Biological Fluids Monoclonal antibodies that bind the native conformation of proteins are indispensable reagents for the development of immunoassays, production of therapeutic antibodies and delineating protein interaction networks by affinity purification-mass spectrometry. Antibodies generated

Preclinical evaluation of a TEX101 protein ELISA test for the differential diagnosis of male infertility Background: TEX101 is a cell membrane protein exclusively expressed by testicular germ cells and shed into seminal plasma. We previously verified human TEX101 as a biomarker for the differential diagnosis of azoospermia, and developed a first-of-its-kind

Discovery of a Human Testis-specific Protein Complex TEX101-DPEP3 and Selection of Its Disrupting Antibodies TEX101 is a testis-specific protein expressed exclusively in male germ cells and is a validated biomarker of male infertility. Studies in mice suggest that TEX101 is a cell-surface chaperone which regulates, through protein-protein interactions, the maturation

Sperm DNA Fragmentation: Consequences for Reproduction DNA fragmentation, or the accumulation of sin- gle- and double-strand DNA breaks, is a common property of sperm, and an increase in the level of sperm DNA fragmentation is known to influence natural reproduction. The effect of sperm DNA fragmentation on male infertility and
