OBJECTIVES: To determine, in a prospective randomized, double-blind placebo-controlled study, the effect of 6 weeks of high-dose (5 g/day) orally administered nitric oxide (NO) donor L-arginine on men with organic erectile dysfunction (ED). PATIENTS AND METHODS: The study included 50 men with confirmed organic ED who were randomized after a 2-week placebo run-in period to receive L-arginine or placebo. A detailed medical and sexual history, O'Leary's questionnaire, a specially designed sexual function questionnaire and a sexual activity diary were obtained for each patient. All participants underwent a complete physical examination including an assessment of bulbocavernosus reflex and penile haemodynamics. Plasma and urine nitrite and nitrate (designated NOx), both stable metabolites of nitric oxide, were determined at the end of the placebo run-in period, and after 3 and 6 weeks. RESULTS: Nine of 29 (31%) patients taking L-arginine and two of 17 controls reported a significant subjective improvement in sexual function. All objective variables assessed remained unchanged. All nine patients treated with L-arginine and who had subjectively improved sexual performance had had an initially low urinary NOx, and this level had doubled at the end of the study. CONCLUSIONS: Oral administration of L-arginine in high doses seems to cause significant subjective improvement in sexual function in men with organic ED only if they have decreased NOx excretion or production. The haemodynamics of the corpus cavernosum were not affected by oral L-arginine at the dosage used.

Effects of long-term oral administration of L-arginine on the rat erectile response.

PURPOSE: Nitric oxide (NO), the neurotransmitter responsible for mediating penile erection in the rat, is synthesized from L arginine by nitric oxide synthase (NOS) in a reaction blocked by L-NAME (N-omega-nitro-L-arginine methyl ester). To determine whether dietary supplementation of L-arginine can stimulate penile erection and whether ancillary pathways for penile erection may exist, a series of experiments were conducted in the Fischer 344 rat. MATERIALS AND METHODS: Adult male (5 month old) and aged (20 month old) rats were fed L-arginine (2.25%) and L-NAME (0.7%) dissolved in tap water for 8 weeks. Animals (n = 6) underwent electrical field stimulation (EFS) of the cavernosal nerve to induce erection and both maximal intracavernosal pressure (MIP) and mean arterial pressure (MAP, mm. Hg +/- SEM) were measured. Tissue and serum levels of L-arginine were measured by an automated amino acid analyzer. Penile eNOS (endothelial) and nNOS (neuronal) content were measured by western blot densitometry. Total penile NOS enzyme activity was measured by the L-arginine to L-citrulline conversion assay. RESULTS: The L-arginine fed animals demonstrated a significant increase in EFS-induced MIP when compared to the controls in both the adult (104 +/- 4 vs. 86 +/- 6, p = 0.04) and aged (87 +/- 5 vs. 66 +/- 4, p = 0.02) animals, without changes in MAP. L-NAME virtually abolished the MIP in adult rats (8 +/- 3, p < 0.0001), while increasing the MAP (186 +/- 8, p < 0.0001). Serum and penile tissue levels of L-arginine were increased by 64-148% in all groups compared to control animals. Penile eNOS and nNOS content remained unchanged in control and treated animals. Penile NOS activity was increased nearly 100% in the L-arginine treated groups vs. controls. CONCLUSIONS: Long-term oral administration of supra-physiologic doses of L-arginine improves the erectile response in the aging rat. We postulate that L-arginine in the penis may be a substrate-limiting factor for NOS activity and that L-arginine may up-regulate penile NOS activity but not its expression. The blockade of penile erection by EFS with L NAME suggests that if ancillary corporeal vasodilator mechanisms develop, a basal level of NO synthesis is still required for activation and relaxation of the corporeal smooth muscle. These data support the possible use of dietary supplements for treatment of erectile dysfunction.

Pessoal

Procurei um médico urologista e ele me receitou Durateston, mas estou com medo de mandar aplicar porque já ouvi falar muito mal desse medicamento.

O lance é que quando treino minha libido fica legal, mas se não treino não tenho libido.

Gostaria de saber de quem conhece/usa/usou quais são os problemas. Será que devo procurar outro médico? A ultima coisa que quero é piorar minha situação. O que é ciclar?

o problema é q vc fica com o local da aplicação muito dolorido nos dias seguintes.
