In recent years, research has focused on the impact that diabetes mellitus (DM) has on male reproductive function. The available evidence has mainly considered type 2 DM (DM2). However, we have previously shown that type 1 DM (DM1) also aects male reproductive health. Given the ecacy of carnitine in the treatment of male infertility, a topic that merits further investigation is its role in the treatment of infertile patients with DM1. Aim. To investigate the ecacy of carnitines for the treatment of asthenozoospermia in DM1 patients. Methods. This was a two-arm single-blind, randomized control trial. The patients enrolled in this study were assigned to the group receiving L-acetylcarnitine (LAC) (1.5 g daily for 4 months) or to the group receiving LAC (same dosage) plus L-carnitine (LC) (2 g daily for 4 months). Serum-glycated hemoglobin levels did not dier significantly after either of the two treatments given. Administration of LAC plus LC showed greater ecacy on progressive sperm motility than single therapy (increase 14% vs. 1% after treatment, respectively). Discussion. The results of this study showed that the administration of LAC plus LC is more eective than the administration of LAC alone. The lower ecacy of LAC alone could be due to the lower overall administered dosage. Alternatively, a selective defect of carnitine transporters at an epididymal level could be hypothesized in patients with DM1. Further studies are needed to clarify this point.
