[Pituitary control of androgen synthesis in the rat embryo].
Removal of the hypophysis by decapitation of the 19--or 20 days--old Rat embryo is followed by a significant decrease in the ability of the embryonic testis to synthesize testosterone and androstenedione from acetate in vitro. It is concluded that pituitary-testis relationships first appear at 19 days of intrauterine life.
