Abstract: | High testosterone concentrations were found in the plasma of male fetus at the stage of sexual differentiation. Then the fetal testis is the principal source of circulating testosterone; its action on the Wolffian duct would occur by the systemic pathway. In female fetus, androgens were synthesized by the gonad and the relatively high levels found in the plasma have probably another source. |
