The adrenal medulla produces the amino acid-derived hormones epinephrine and norepinephrine (adrenaline and noradrenaline) Estrogen and progesterone // development of female reproductive tissues and secondary sex characteristics. Testosterone // development of male reproductive tissues and secondary sex characteristics. Aldosterone // regulation of blood pressure and electrolyte balance.
