Hello dear, Thank you for your question. Erectile dysfunction (ED) is a common problem that affects the life of many men. It is of crucial importance that you understand ,that not every problem with erection, is necessarily a definitive case of ED. Factors that can cause the problem you have been experiencing may include the following: 1- Conditions like: Diabetes, High Blood Pressure etc. 2- Psychological circumstances like: stress, anxiety, extended use of pornographic materials etc. 3- Certain drugs: like ant-depression drugs, some anti-hypertensive drugs etc. 4- Age is another factor as ED is common among elderly people. 5- Hormonal changes: thyroid disease, low levels of testosterone etc. Psychological stress is a common cause among young males. There is a simple way to differentiate if your problems come from stress. If your morning erection is preserved (erection when waking up in the morning), there is a high probability that your problems come from psychological factors. A consult with an urologist can give a more specialised insight for the causes of your condition. He/she may ask you to run some tests and/or an ultrasound of your penis in order to establish the cause of your problem. Some causes are perfectly treatable and you can regain your sexual health (ie if you have low levels of testosterone, substitute therapy will resolve your problem) There are many therapeutic options for the treatment of ED: 1- Drugs like Viagra, Cialis,Levitra etc that you take before you are planning to have sexual intercourse. These type of drugs are perfectly safe to use and have minor side effects like: headaches, dizziness etc which tend to abate in time. You need a consult with your doctor to find out if the are suitable for you. 2- Vacuum devices that create a mechanical pressure to give you an erection. They are very easy to use but may cause some discomfort, bruises etc. 3- Penile prosthesis when all the above measures are not effective in taking care of your problem. I hope this helped. Don t hesitate to contact me, if you have any further questions. All the best. Dr. Alma
