Mechanism of action

Testosterone undecanoate is a long-acting androgen replacement therapy that restores physiological testosterone levels in hypogonadal men. PDE-5 inhibitors (such as sildenafil, tadalafil, or vardenafil) block phosphodiesterase-5 enzyme, preventing degradation of cGMP and promoting smooth muscle relaxation and vasodilation in the corpus cavernosum. The combination addresses both hormonal deficiency and erectile dysfunction.
