Relative reactivity of seminal plasma IgG with fucose-specific lectins

Group	IgG (mg/l)	Relative reactivity with lectins (AU)
		AAL	UEA	LTA
Normal (n = 17)	67.7 ± 29	1.2 ± 0.3	0.42 ± 0.2	0.35 ± 0.3
Leukocytospermia (n = 28)	131.7 ± 103	0.82 ± 0.3	0.34 ± 0.3	0.51 ± 0.4
	p < 0.02	p < 0.002

The concentration of IgG in seminal plasmas was determined by radial immunodiffusion according to Mancini et al. [22], using goat anti-human IgG polyclonal antibodies. In both seminal plasma groups, the relative reactivity of IgG (100 ng/100 μl) with fucose-specific lectins was determined by lectin-ELISA [23] using biotinylated lectins AAL, UEA and LTA, and expressed in absorbance units (AU). Results are given as mean value ± standard deviation. A two-tailed p-value of less than 0.05 was considered significant
