Circannual cycle in plasma testosterone levels in man.

A G Smals, P W Kloppenborg, T J Benraad.

Abstract

In a groups of 15 healthy male subjects a statistically significant circannual cycle in plasma testosterone levels was assessed by sampling blood at 3-monthly intervals. Peak levels were found in summer and early autumn and a nadir in the winter and early spring.
