Abstract
The dynamics of serum testosterone was studied in laboratory male rats kept separately from females. Infradian rhythm of changes in testosterone level equal to 4 days and ultradian (within 24 h) periods equal to 160 and 480 min were detected. The maximum serum level of testosterone in male rats was synchronized with the greatest number of estrous females.Entities:
