Cadmium Concentrations in Blood and Seminal Plasma: Correlations with Sperm Number and Motility in Three Male Populations (Infertility Patients, Artificial Insemination Donors, and Unselected Volunteers)

Table 2 The relationship between metal levels in blood and seminal plasma in three populations of men.^a

Subjects	Metal 1	Metal 2	n	r	P value
Group 1: infertility patients	Seminal plasma cadmium	Blood plasma cadmium	91	−0.092	0.386, NS
Group 2: AI donors	Seminal plasma cadmium	Blood plasma cadmium	14	−0.029	0.916, NS
Group 3: general population volunteers	Seminal plasma cadmium	Blood plasma cadmium	35	0.210	0.225,NS

^aSpearman correlations were performed using mean values for cadmium levels for each subject, r = Spearman correlation coefficient; NS, not significant.
