SEMEN CULTURE, LEUKOCYTOSPERMIA, AND THE PRESENCE OF SPERM ANTIBODIES IN SEMINAL HYPERVISCOSITY.

Seminal hyperviscosity is generally thought to reveal genitourinary infection. The aim of the present work was to study this hypothesis. A total of 65 semen samples were obtained from males presenting for infertility screening. The samples were evaluated according to WHO criteria and microbiologically investigated, including culturing for Mycoplasma hominis and Ureaplasma urealyticum, and microscopic observation of Chlamydia trachomatis by a direct fluorescence assay. Determination of local antisperm antibodies was performed. Semen was categorized according to consistency: normal (n = 31) and high (n = 34). No difference was recorded either in the number of positive cultures, or in the number of species found in each sample. The number of white blood cells and the percentage of antibody-bound sperm showed no difference in the groups under study. There was no association between seminal hyperviscosity, positivity in semen cultures, number of species isolated in semen cultures, leukospermia, or presence of sperm antibodies. Further studies should be performed considering the evolution of the genital-infected patients to clarify the etiology of the hyperviscosity. [ABSTRACT FROM AUTHOR]
