Male factors account for 20% to 50% of infertility cases, and infection in the genitourinary tract may play a contributing role in up to 15% of male infertility. Leukocytospermia is a well-known indicator of infection or inflammation in the male sex glands and the urogenital tract. Although great deal of effort has been expended to elucidate definite management strategies in infertile men with ...

Leukocytospermia has been associated with notable adverse effects on semen parameters and sperm function. The present study was undertaken to identify men with leukocytospermia and prostatitis in an infertility population and assess the effects of various treatments. One million white blood cells (WBC)/ml semen was defined as leukocytospermia. An expressed prostatic fluid was analyzed for the p...

BACKGROUND It is not well established whether the increased number of leukocytes in the seminal fluid impairs the outcomes of assisted reproductive technology (ART). This investigation analysed the outcomes of the intracytoplasmic sperm injection (ICSI) and intracytoplasmic morphologically selected sperm injection (IMSI) cycles in couples in which the male partner exhibited 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. ...

OBJECTIVE Discuss the changes and roles of PAF in the reproductive tract infection by observing the expression of platelet activating factor (PAF) and tumor necrosis factor α (TNF-α) in seminal plasma of patients with leukocytospermia. METHODS The seminal plasma was obtained from 22 cases of leukocytospermia and 15 cases of normal males; the peroxidase dyeing method was adopted for seminal pl...

This study set out to establish a new method, using flow cytometry, to evaluate leukocytes in semen. Ejaculates of 59 males, asymptomatic for genitourinary infections, were examined. Routine semen analyses were carried out as well as peroxidase and polymorphonuclear granulocyte-elastase detection. Leukocytes were detected combining flow cytometry and monoclonal antibodies (anti-CD45, anti-CD53)...

Background Leukocytes linked directly and indirectly to reactive oxygen species (ROS) formation. 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 1×106 WBC/mL (low-level leukocytospermia) still can produce a detectable amount of ROS, impairing sperm function and lowering the chances of pregnancy. Low concen...

To investigate the role of increased seminal leukocytes in enhancing reactive oxygen species (ROS) production by human spermatozoa.A prospective study. Male infertility clinic.Forty-eight infertile men. Standard semen analysis. Assessment of sperm nuclear DNA damage by sperm chromatin structure assay. Incubation of spermatozoa from nonleukocytospermic samples with blood neutrophils. Spontaneous...
