The Facts
Erectile difficulty is the frequent or consistent inability to get
or sustain an erection of the penis sufficient to engage in sexual intercourse.
While most men occasionally fail to get an erection, or lose one prematurely
during sexual activity, a large number of men suffer from these problems regularly.
Accurate statistics are lacking on how many men are affected by the condition,
but some doctors estimate that about half of men aged 40 to 70 have frequent
problems achieving or maintaining an erection. Erectile difficulties are far
more common in older men.
