We report two cases of bilateral renal angiomyolipoma with tuberous sclerosis who had skin lesions like butterfly shaped adenoma sebaceum on face, shagreen patch on back, leaf-shaped hypopigmented spot on both extremities, mental retardation, and seizure, which they are treated unilateral simple nephrectomy and selective arterial embolization, each other.

PURPOSE: To determine whether seminal malondialdehyde and carbonyl group have any relation to sperm motility. MATERIALS AND METHODS: Human semen samples were obtained by masturbation after 3 days of abstinence from patients consulting an infertility clinic. Using conventional semen analysis, samples were divided into two groups according to sperm motility (group 1: motility > OR =50%, group 2: motility <50%). Malondialdehyde and carbonyl group were measured in whole semen. RESULTS: The amount of malondialdehyde and carbonyl group was slightly lower in group 1 than group 2. CONCLUSIONS: Although the difference between the groups was not statistically significant, it seems possible that malondialdehyde and carbonyl group, which are produced from reactive oxygen, are negatively correlated with sperm motility.
