Scrotal hemorrhage after testicular sperm aspiration may be associated with phosphodiesterase-5 inhibitor administration: a retrospective study

Background Scrotal hemorrhage after testicular sperm aspiration (TESA) is uncommon in clinical operation. Phosphodiesterase-5 inhibitors (PDE5i) are commonly given to men who have difficulty providing a sperm sample for assisted reproductive technique such as in vitro fertilization. In this study, we examine the incidence of scrotal hemorrhage after TESA in men who received a PDE5i.
