gnrh release from the hypothalami of castrated rats treated with testosterone propionate , 100 or 500 mug daily , was 25.0+/-3.4 pg/h and 27.9+/-3.6 pg/h , which is significantly greater ( p < 0.05 and p < 0.01 , respectively ) than that from hypothalami of castrated rats treated only with sesame oil.a similar decrease in gnrh release from hypothalami of hypophysectomized rats and prevention of this decrease by treating the hypophysectomized rats with testosterone propionate is evidence that the observed effects of testosterone are not mediated via luteinizing hormone and ( or ) follicle-stimulating hormone secretion .
