Human seminal transferrin: correlation with seminal and hormonal parameters.

Transferrin (TF) concentrations were assessed in semen from 10 fertile controls and 79 infertile patients by a radioimmunoassay method. A positive correlation between seminal TF concentration and sperm count was found in the whole sample of patients and within the control group. A statistically significant difference was found between azoospermic and severely oligospermic patients and all the others. No correlation was found with other seminal parameters or hormonal values.
