Methods： Fifty-one patients referred to our Sterility Center for semen analysis were selected. Sperm parameters were assessed before and after patient＇s treatment with beta-glucan, lactoferrin, papaya, and vitamins C and E. DNA damage was assessed by the acridine orange test and sperm structural characteristics were evaluated by transmission electron microscopy. Results： After 90 days of treatment, an increase in the percentage of morphologically normal sperm （17.0 ± 5.2 vs. 29.8 ± 6.5） and total progressive motility （19.0± 7.8 vs. 34.8 ± 6.8） were detected. Structural sperm characteristics as well as chromatin integrity were also improved after treatment. In terms of leukocyte concentration in seminal fluid, a significant reduction was recorded （2.2 ± 0.9 vs. 0.9± 0.2）. Conclusion： The treatment of an inflammatory process by the synergic action of immune modulators and anti-oxidants could protect sperm during maturation and migration, leading to improved sperm function. （Asian JAndrol 2008 Mar;. 10： 201-206）展开更多

The presence of more than one million peroxidase positive white blood cells (WBC) per ml is considered abnormal and is labeled as “leukocytospermia” [1]. But, is there any deterioration in the semen parameters in cases where the number of leukocytes is higher than “normal”, or is it an indication for infection? Objective: To test the significance of the presence of leukocytes in the semen sample. Design: A retrospective randomised study. Materials and Methods: 6481 semen samples were divided into two groups according to the availability of the leukocytes. Group I includes samples with ≤1 × 106 leukocyte/ml (n = 3948) and group II includes samples with >1 × 106 leukocyte/ml (n = 2533). Semen samples were from partners of couples undergoing infertility evaluation. Specimens were collected by masturbation, and subjected to routine semen analysis including count, motility, sperm morphology (assessments were performed according to the Tygerberg strict criteria), number of leukocytes present (identification of Leukocytes was done using peroxidase staining) and Mixed Antiglobin Reaction (MAR) test was done for detection of sperm surface antibodies. All semen samples from group II were sent for culture. Results: A comparison in the mean ± standard deviation (mean ± SD) between the two groups showed statistical significant differences in the mean ± SD motility (55.9 ± 27.8 vs 53.4 ± 27.3, P Conclusion: From the results obtained, we support the studies showing that the presence of leukocytes may not be linked to infection. Future studies are needed to verify the effect of lipoperoxidation process as a result of leukocytes’ presence and to determine the cut off number of leukocytes in semen to be considered of importance since the semen parameters were affected significantly.展开更多

Methods: It is a prospective study consisting of 30 infertile men and 12 fertile normozoospermic volunteers. A full history, clinical examination and scrotal ultrasound were done to exclude other related factors such as smoking and varicocele. Presence of white blood cells (WBCs) in semen samples was evaluated by peroxidase staining. Lipid peroxidation in spermatozoa was induced after incubating with ferrous sulphate (4 mmol/L) and sodium ascorbate (20 mmol/L). Induced peroxidation of spermatozoa was assessed by determining the production of thiobarbituric acid reactive substances (TBARS). Acrosin activity was measured using the gelatinolysis technique. The halo diameters around the sperm heads and the percentages of spermatozoa showing halo formation were evaluated. An acrosin activity index was calculated by multiplying the halo diameter by the halo formation rate. Results: A significant difference was observed in acrosin activity parameters and TBARS levels between samples with WBCs (>1×106/mL of ejaculate) and those without. This difference was also noted between the normozoospermic and the oligoasthenoteratozoospermic semen samples. The TBARS production by spermatozoa had a significant negative correlation with the acrosin activity index (r = -0.89, P <0.001). Conclusion: The presence of oxidative stress in an individual with leukocytospermia and/or abnormal semen parameters is associated with impaired sperm function as measured by its acrosin activity.展开更多
