Antioxidant treatment with carnitines is effective in infertile patients with prostatovesiculoepididymitis and elevated seminal leukocyte concentrations after treatment with nonsteroidal anti-inflammatory compounds

Abstract

Objective: To evaluate whether the association of antioxidants and anti-inflammatory compounds may be beneficial in treatment of patients with abacterial prostatovesiculoepididymitis (PVE) and elevated seminal leukocyte concentrations.

Design: Open, prospective, random study.

Setting: Academic research environment.

Patient(s): Ninety-eight patients with PVE who had increased seminal leukocyte concentrations (>1 x 10(6) cells/mL). Carnitines (group A; n = 30) or nonsteroidal anti-inflammatory drugs (group B; n = 16) for 4 months; nonsteroidal anti-inflammatory drugs for 2 months, followed by treatment with carnitines for 2 months (group C; n = 26); or nonsteroidal anti-inflammatory treatment given concomitantly with carnitines (group D; n = 26) for 4 months.

Main outcome measure(s): Semen variables, production of reactive oxygen species, and pregnancy outcome were evaluated before and after treatment and following a 3-month washout period.

Result(s): Patients in group C had the highest reduction in production of reactive oxygen species associated with increased sperm motility and viability. Groups B and D experienced intermediate effects, and group A experienced the least effect.

Conclusion(s): Antioxidant treatment with carnitines is effective in patients with abacterial PVE and increased seminal leukocyte concentrations if these patients have been pretreated with nonsteroidal anti-inflammatory drugs.
