QUINTERO PEREZ, William et al. Efecto del estrés oxidativo sobre la calidad del semen de pacientes infértiles con leucocitospermia. Rev Cubana Invest Bioméd [online]. 2000, vol.19, n.3, pp. 183-185. ISSN 1561-3011.
Leucocytospermia has been associated with alterations of the quality of semen. However, the mechanisms involved in this damage have not been exactly determined yet. This paper was aimed at knowing whether leucocytospermia and its contribution to the oxidative stress generated in the reproductive system may affect the quality of semen. To this end, a sample of 52 male patients members of infertile couples that were attended in the department of infertility of the National Institute of Endocrinology, in 1998 and 1999, was studied. The semen was analyzed according to the habitual procedures. Malondialdehyde, catalase and superoxide dismutase were also determined. The superoxide dismutase activity was negatively correlated to the number of leucocytes and positively to the mobility b and the mobility a+ b. It was concluded that leucocytes may affect the balance between the factors that favor and prevent the oxidative stress. The protection against the oxidative stress is beneficial for the quality of semen
