Men who take Viagra are being warned that the treatment will not work if the reason for their erectile dysfunction lies with low testosterone levels according to Dr Geoffrey Hackett, a sexual health specialist at the Good Hope Hospital, Birmingham.
Although around 40% of men over 40 experience erectile dysfunction, more than 1 in 5 men experience erectile dysfunction resulting from a low level of testosterone. It is normal for the levels of this hormone to deplete over time however abnormally low levels of testosterone can be an indicator for future issues such as cardiovascular events, diabetes and osteoporosis.
Quite often we have men for whom Viagra and other medications such as Cialis and Levitra do not work and we always recommend a check up with a doctor face to face. Even if Viagra is working for a patient it is always advisable to rule out underlying health problems as the root cause.
