Abstract:
PURPOSE: This study was performed to investigate whether rebamipide is useful in the treatment of male infertility due to oxidative damage. MATERIALS AND METHODS: 50 infertile males with elevated reactive oxygen species (ROS) in their semen were enrolled. All patients were given an oral daily dose of 900mg rebamipide for at least 3 months. The concentrations of rebamipide and ROS, and the levels of lipid peroxidation, sperm motility, vitality and fertilizing capacity were measured by a high-performance liquid chromatography (HPLC) fluorescent method, chemiluminescence, the thiobarbituric acid method, a computer assisted semen analyzer, eosin-nigrosin staining and hypo-osmotic swelling test, respectively. Additionally, the clinical outcomes, including pregnancy and delivery, were observed at the gynecology outpatient and IVF clinics. RESULTS: The rebamipide concentration in semen after medication was 220.77+/-327.84ng/ml (SD), with a large deviation, but this was higher than the level found in the serum, which was 126+/-76ng/ml (SD). The levels of seminal ROS and lipid peroxidation were significantly decreased according to the duration of treatment (p<0.05). The sperm vitality and fertilizing capacity were also significantly improved at 2-3 months post treatment (p<0.05). Out of the 41 cases with trial pregnancies, 20 (48.8%) became pregnant, consisting of childbirth, miscarriage or ongoing in 17, 2 and 1 case, respectively. Side effects were observed in only 1 case (2%) with self-limits. CONCLUSIONS: These results suggest that rebamipide is an effective free radical scavenger, which may be useful as an oral antioxidant in patients with male infertility due to oxidative damage caused by high tissue affinity to the male accessory organ, antioxidant effect and the improving effect of seminal parameters.
