Someone told me since i am 19 with low testosterone (225 ng/dl), cialis will not work to help my erections. is this true? i hope not cuz im a virgin!!

Don't worry : A single measurement of testosterone is not diagnostic. To know whether you have low testosterone, a pooled study should be performed. This is done by collecting a tube of blood and then waiting 30 minutes for another and then 30 minutes for a third sample. These are combined and testosterone is then measured. At your age, if you have low testosterone, you should see an endocrinologist.
