Sperm Quality and Seminal Biochemical Parameters in Infertile Men with and without Leukocytospermia

Antioxidant levels in blood and seminal plasma and their impact on sperm parameters in infertile men.

Excess reactive oxygen species (ROS) beyond the scavenging capacity of antioxidants leads to DNA damage and oxidation of lipoprotein components at the cellular and subcellular level. The oxidative stress (OS) adversely affects sperm function by altering membrane fluidity, permeability and impairs sperm functional competence. In the present study, the OS status in seminal plasma and blood serum ...

Onm-6: Apoptosis and the Quality DecreaseOf Sperm Parameters in Infertile Men.

Reactive oxygen species and sperm DNA damage in infertile men presenting with low level leukocytospermia

BACKGROUND Leukocytes contribute directly and indirectly to reactive oxygen species (ROS) production. Although leukocytospermia is defined as the presence of ≥ 1 × 106 white blood cells/mL (WBC/mL) in a semen sample, the presence of less than 1×10(6) WBC/mL (low-level leukocytospermia) can still produce a detectable amount of ROS, impairing sperm function and lowering the chances of pregnancy. ...

Sperm chromatin structure, semen quality and lead in blood and seminal fluid of infertile men.

BACKGROUND Exposures to lead above the threshold value of 50-60 μg/dL have been linked to diminished semen quality parameters. Worldwide, the lead exposure has been diminished during the last years. Therefore, it has become of a great concern to examine the effects of lead exposures on semen quality at low levels of exposure. OBJECTIVE To evaluate the effect of low level (<20 μg/dL) blood lea...
