[Secretion into the plasma of testosterone and estradiol 17 beta by the human testicle. Value of the study in male sterility].
The levels of oestradiol and of testosterone were estimated in the spermatic and in the perpheral veins in two series of 13 subjects.  The one was a control group and the other stimulated with 10,000 International Units of chorionic gonadontrophir (II.C.G).  The follwing conclusions can be drawn. --the first is that the testis secretes simultaneously testosterone and oestradiol 17 beta --the second is that the level of oestradiol is significantly raised after the administration of II.C.G. whereas the level of testosterone hardly alters.  This leads on to the supposition that oestradiol does not arise from the same source in the testis as testosterone.
