AIM: To investigate the effects of 17beta-estradiol (E2), Peganum harmala extract (PHE) and caloric restriction (CR) on various testis parameters during aging. METHODS: Twelve month-old male rats were treated for 6 months with either E2 or PHE, or submitted to CR (40%). RESULTS: Our results show that estrogens and CR are able to protect the male gonad by preventing the decrease of testosterone and E2 levels as well as the decrease of aromatase and estrogen receptor gene expressions.
