Tests such as the bulbocavernosus reflex test are used to determine if there is sufficient nerve sensation in the penis.

A physician measures the latency between squeeze and contraction by observing the anal sphincter or by feeling it with a gloved finger inserted past the anus.

Hay una causa común en nuestra sociedad actual que es la “inactividad sexual”. Sin que exista ningún trastorno orgánico ni psicógeno, el individuo, por razones diversas, va distanciando progresivamente su actividad sexual, lo que va a afectar a las distintas fases de la respuesta sexual: deseo, excitación, orgasmo y satisfacción, causando frecuentemente anorgasmia femenina o impotencia masculina.
La Disfunción Eréctil es la incapacidad de obtener y mantener una erección para conseguir una relación sexual satisfactoria. Esta sintomatología debe persistir durante seis meses para ser considerada una patología. Además, debe haber un fallo cada cuatro relaciones sexuales para que el hombre empiece a sospechar que tiene un problema más allá de un simple gatillazo. En concreto, los signos que hacen sospechar la existencia de Disfunción Eréctil son, además de los citados: erecciones espontáneas por la mañana menos frecuentes y con menor rigidez; si se llega al clímax más rápido, en menos tiempo o con una erección incompleta; en caso de pérdida de erección al cambiar de postura; o cuando no se consigue una erección en absoluto.
