[Effect of sex steroids on the rat testicular blood supply].
The effect of oestradiolundecilate and testosterone oenanthate on the blood supply of the testicle of rats was investigated by means of the Xe-133 tissue clearance. The investigation shows the following results: 1. Oestradiolundecilate leads to a highly significant decrease of the blood supply of the testicles. 2. The effect of testosterone oenanthate depended upon the dosage. 0.3 mg three times a week led to a reduction of the blood supply, whereas below 3.0 mg three times a week no difference of the values of blood supply appeared in comparison to the initial values. Connections between the functional changes evoked by the application of the sexual steroids and the behaviour of the blood supply are discussed.
