Levitra online pills, which are so popular today, have no effect on semen parameters with prolonged use. Effect of inhibitors of PDE-5 on the characteristics of the sperm and the level of reproductive hormones was studied in men with erectile dysfunction. In a randomized, double-blind, placebo-controlled study have been involved 200 men, taking 20mg of Levitra or a placebo for 6 months. Assessed measure was the percentage of patients with more than 50% reduction in sperm concentration compared with baseline data, and placebo. The difference between patients (Vardenafil minus placebo) with more than 50% reduction sperm concentration after 6 months of treatment was 0.07% (95% CI, -8.53% to 8.39%). Generic Levitra had no clinically significant effect on any other semen parameters, the level of reproductive hormones compared with placebo.
The study shows that Vardenafil had no negative impact on semen parameters (concentration, number of sperm in the ejaculate, morphology and motility) and the concentration of sex hormones in the application of the maximum soluble dose for 6 months.
Levitra online is available in 10, 20 and 50mg dosages. It is advisable to start with small doses - 10mg, no more than once a day. Further, the dose may be increased.
