Welcome to the just answer website.
There are various over the counter supplements(Like Nitrozyt) available but there is no credible medical evidence that the supplements are safe, effective, and perform the way they claim.My advice is don't go for any pills or any herbal products you have seen in advertisements for penis enlargement.There is no scientific proof about their effectiveness in general.
First the cause of ED(erectile dysfunction) should be evaluated.Its most common causes are: aging,diabetes,hypertension (high blood pressure
),cardiovascular diseases,cigarette smoking,nerve or spinal cord damage,low testosterone
levels,certain medications,depression and anxiety.
Various tests like ultrasound,neurological evaluation,Dynamic infusion cavernosometry and cavernosography (DICC),Nocturnal tumescence test.The treatment includes Oral medications like Sildenafil
,Tadalafil,life style improvements (for example; quitting smoking, and exercising more), Inserting medications into the urethra (intra urethral suppositories), penile prostheses,testosterone.Prostaglandin E1 (intraurethral alprostadil or MUSE) can be inserted in a pellet (suppository) form into the urethra to attain erections.
So I advice you to make an appointment with your urologist for these tests & examination to know the exact cause & then treatment will be done accordingly.Please feel free to ask if you have any other question.
