SYNOPSIS

Plasma testosterone values were obtained by the RIA method from two groups of cluster headache male patients in separate laboratories. In each group testosterone levels were compared between controls and cluster patients in active and remission periods. Significantly lower values were found in active cluster patients when compared to either cluster-remission or controls. The results are preliminary and suggest a possible association of lowered plasma testosterone levels with active cluster period in cluster headache male patients.
