Everything you need to know
What is the cause of erectile dysfunction?
Testosterone is important for muscle mass, bone strength, energy levels, libido, erections, mood and concentration, among other things. It also plays a role in sperm production and the maintenance of male characteristics.
Is it treatable?
A deficiency can cause symptoms such as reduced sex drive, erectile dysfunction, fatigue, reduced muscle strength, increased fat, feelings of depression and difficulty concentrating. These symptoms often develop gradually.
What is erection dysfunction?
Testosterone is the most important male sex hormone. It is mainly produced in the testicles and plays a major role in both physical and mental processes. Everyone has testosterone, but men have much more of it than women.
What can I expect?
Both pills are effective. But which one is best for your specific needs is another question. While Sildenafil can take 30 minutes to an hour to take effect and work for 4-5 hours, Tadalafil can work within 30 minutes and last up to 36 hours.
