摘要: Abstract Sexual behavior declines in old male rats, and testosterone therapy does not restore the to levels found young males. If as a result of aging, males have less capacity aromatize or reduce testosterone, dihydrotestosterone plus estradiol treatment should be more effective than restoring sexual castrated In test this hypothesis, (24 months) Fischer 344 given injections propionate (TP) (DHTP) benzoate (EB) that sham-operated vehicle were observed. The DHTP/EB proved overall TP increasing second experiment, (3 (30 tested verify reduced effectiveness was age-related. Testosterone equally most measures no these same measures. Neither hormone increased level Since is stimulating males, likely explanation for decreased responsiveness rats.
