“Addition of androstenedione (500 ng/mL) to the culture medium enhanced 25 ng T3 induced testosterone and oestradiol secretions.”
“While androstenedione potentiated the stimulatory effect of T3 (25 ng) on LH (25 ng) induced testosterone and oestradiol secretions, it reversed the inhibitory effect of 50 ng T3 on LH mediated testosterone secretion which was accompanied by a decrease in oestradiol secretion.”
