Feasibility Study of Video Telehealth Clinic Visits in Urology. The Journal of Urology, 201(Supplement 4), e545-e545.

Oral Administration

Low testosterone or testosterone deficiency, also known as hypogonadism, is a condition in which patients develop symptoms such as low sex drive, erectile dysfunction (ED), and fatigue because the body doesn’t produce enough testosterone.

Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly.

Side Effects

Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body's normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, sildenafil helps to maintain an erection after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection. Sildenafil is also used in both men and women to treat the symptoms of pulmonary arterial hypertension.

Some side effects can be serious. If you experience any of the following symptoms, call your doctor immediately:

This is a type of high blood pressure that occurs between the heart and the lungs. When hypertension occurs in the lungs, the heart must work harder to pump enough blood through the lungs.
