Abstract

The authors retrospectively examined whether long-term administration of tranilast improves semen parameters in severe oligoasthenozoospermia. Fifty-two patients presenting with sperm concentration of less than 10 x 10(6) sperm/mL were enrolled. Subjects were partitioned into 3 groups as follows: patients displaying an atrophic testis with elevated (FSH) (group 1), patients exhibiting normal testicular volume with elevated FSH (group 2), and patients with normal testicular volume and normal FSH levels (group 3). Tranilast (300mg/day) was administered until pregnancy was achieved or for a period of up to 12 months. Sperm concentration was significantly increased at 3 months in 16 subjects (44%) in groups 1 and 3. In group 2, sperm concentration was increased at 12 months (5 of 16 subjects; 31%). Total sperm count was obviously elevated at 3 months in groups 1 and 2, and at 6 months in group 3. Six pregnancies were achieved via natural intercourse. Tranilast, a mast cell blocker, demonstrates a certain clinical benefit in terms of improvement of semen parameters involving severe oligoasthenozoospermia, but it does not appear to afford clinical benefit in long-term administration.
