Although the iron-chelating protein lactoferrin is secreted by the seminal vesicles, the precise role of lactoferrin in semen is unclear. This study aimed to determine whether there is any association between seminal lactoferrin concentrations and normal and abnormal semen samples with and without leucocytospermia. Lactoferrin concentrations were measured by radial immunodiffusion of semen samples from 368 men attending a regional andrology referral center. Routine seminal analysis, including the presence of leucocytospermia, was also performed. Results showed increased seminal lactoferrin in samples showing oligospermia (13.3 mg/100 ml) and oligoasthenospermia (13.4 mg/100 ml) compared to normospermic samples (11.2 mg/100 ml). There were no significant differences in seminal lactoferrin between normospermic samples and azoospermic samples or asthenospermic samples with normal sperm density. Although there was a trend toward increased lactoferrin concentration with leucocytospermia, this was not significant. Possible causes for raised lactoferrin in association with oligospermia are discussed.
