[Serum testosterone after HCG in thyroidectomized or hyperthyroid male rats (author's transl)].
Serum testosterone levels were measured by radioimmunoassay in young male rats before and after IM HCG (500 IU) in basal conditions, after thyroidectomy, or during thyroxine administration. Basal testosterone levels decreased significantly with time in control group (p less than 0.025) and in thyroidectomized rats (p less than 0.025). After HCG, testosterone increased in the 3 groups. There was no difference between control and hypothyroid groups but a lower response (p less than 0.005) in hyperthyroid rats.
