Vardenafil is a potent and highly selective phosphodiesterase type 5 (PDE5) inhibitor with a potency about 10-fold higher than sildenafil.伐地那非是一種強效、高選擇性的5型磷酸二酯酶(PDE5)抑制劑，對PDE5的抑制作用約為西地那非的10倍。

Vardenafil, as a novel and highly selective phosphodiesterase 5 inhibitor, has been proved by many clinical trials to be quite safe for the cardiovascular system.伐地那非是一種新型高選擇性磷酸二酯酶5型抑制劑，它對心血管系統的安全性已被多項臨牀試驗所證實。

Objective: To compare the differences of expressions of adenylyl cyclase (AC) and phosphodiesterase (PDE) in ejaculated spermatozoa between healthy volunteers and the patients with asthenospermia.目的：比較腺苷酸環化酶（AC）和磷酸二酯酶（PDE）在活動力正常和活動力低下的人精子表達的差異。 ^[1]
