The IIEF-EF test

One of the most widely used questionnaires for erectile dysfunction is the IIEF-EF test. The short test can help you determine if you may have erectile dysfunction.
For the test consider the following:

✔ sexual activity includes intercourse, caressing, foreplay and masturbation
✔ sexual intercourse is defined as sexual penetration of your partner
✔ sexual stimulation includes situation such as foreplay, erotic pictures etc.
✔ ejaculation is the ejection of semen from the penis (or the feeling of this)
✔ orgasm is the fulfillment or climax following sexual stimulation or intercourse

Choose the most appropriate response for each question and add up the scores then you can contact your doctor for evaluation of the results obtained by filling out the IIEF-EF test.
