Leukocytospermia is associated with increased   reactive oxygen species production by human spermatozoa.
OBJECTIVE: To investigate the role of increased seminal leukocytes in enhancing reactive oxygen species (ROS) production by human spermatozoa. DESIGN: A prospective study. SETTING: Male infertility clinic. PATIENT(S): Forty-eight infertile men. INTERVENTION(S): Standard semen analysis. Assessment of sperm nuclear DNA damage by sperm chromatin structure assay. Incubation of spermatozoa from nonleukocytospermic samples with blood neutrophils. MAIN OUTCOME MEASURE(S): Spontaneous and ... إقراء المزيد

Increased sperm nuclear DNA damage in normozoospermic infertile men: a prospective study.
OBJECTIVE: To evaluate levels of sperm nuclear DNA damage in infertile men with normal and abnormal standard semen parameters. DESIGN: Prospective study. SETTING: Male infertility clinic. PATIENT(S): Ninety-two men seeking infertility treatment and 16 fertile volunteers. INTERVENTION(S): Standard semen analysis was performed according to the World Health Organization guidelines.

Negative effects of increased sperm DNA damage in relation to seminal oxidative stress in men with idiopathic and male factor infertility
OBJECTIVE: To examine the effects of increased sperm DNA damage in relation to seminal oxidative stress in men with idiopathic and male factor infertility. DESIGN: Prospective study. SETTING: Infertility clinic at a tertiary care academic institution. PATIENT(S): Ninety-two infertile men with normal female partners. Sixteen fertile donors served as the control group. INTERVENTION(S): Standard semen analysis and assessment of levels ... إقراء المزيد

Increased sperm nuclear DNA damage in normozoospermic infertile men: a prospective study.
Conclusions: The results of this study indicated a significant incresae of SCSA-defined sperm nuclear DNA damage can be found in sperm from infertile men with normal standard semen parameters. Therefore, sperm DNA damage analysis may reveal a hidden abnormality of sperm DNA in infertile men who were previously classified as idiopathic based on apparantly normal standard semen parameters. إقراء المزيد
