What is the normal length of the penis?
Usually the normal length of the penis during erection is 10-15 cm and if yours is less than 7 cm it's considered small and requires an assessment by the urologist 

How to increase the length of the penis?
Firstly, you should visit the urologist in order to make a full assessment to your condition especially if your penis length is less than the normal one during erection. As the small penile length might need an intervention such as silicone injections or pump implants inside the penis. Furthermore, it should be noted that the products that are being sold in the market for penile enlargement are not effective as studies have shown and we do not recommended them to be used.

What are the required medical tests ?
Usually you condition does not require any medical tests except the clinical examination to be done by the urologist

Causes of short penis:

• Old age
• Obesity
• Previous prostate surgery
• Drinking alcohol and smoking
• others

Advice:
If the length of your penis is less than normal, it is recommended to see a urologist.
