Abstract
This study was aimed at investigating whether semen characteristics in different clinical diagnoses of infertility are associated with PMN elastase, IL-6, IL-8, IL-1beta and TNFalpha levels detected in seminal plasma. Sixty-eight patients were divided into groups according to their clinical diagnosis: idiopathic infertility (group I), varicocele with infections (group II), varicocele (group III), infections (group IV), controls (group V). Physical examination and scrotal Eco-color Doppler was used to detect the varicocele. Patients with positive bacteriological semen analysis were considered as having an infection of the male reproductive tract. Samples were examined by light microscopy and transmission electron microscopy (TEM). TEM data were quantified with a mathematical formula furnishing a fertility index and the percentage of sperm apoptosis, immaturity and necrosis. PMN elastase/alpha1-PI complex levels were determined by ELISA and IL-6, IL-8, IL-1beta, TNFalpha by Bio-Plex Cytokine assay. Sperm concentration (I-II: p < 0.005; III-IV: p < 0.0001), motility (I-IV: p < 0.0001) and the fertility index (I: p < 0.005; II-IV: p < 0.0001) were significantly lower in the groups vs. controls, whereas sperm pathologies, except for...Continue Reading
