During the last decades, different and diverse criteria have been used to define this entity, although since 2013 it has adopted the definition of the International Society for Sexual Medicine (ISSM). Premature ejaculation may be primary (occurs from the time an individual begins sexual relations) or acquired (appears at some point in his life, with previous normal sexual performance), and is characterised by:
Two other premature ejaculation syndromes have also been recently proposed:
As for the frequency of this pathology, the biggest problem in measuring it is that, at the time when the largest studies were carried out, there was no agreed definition of the entity, so percentages of up to 31% of men aged 18-59 years have been described in the literature. Today, it is considered to affect around 5% of the older male population.
For the acquired type, the causes may be varied, such as the presence of urethritis, hormonal disorders or psychogenic factors. However, there is no clear etiology for the vast majority of the cases.
» Clinical interview with a super-specialised andrologist..
Personal background will be assessed and research will be done on the onset of symptoms, latency time, erectile function, time since the onset of symptoms, perception of control over the disease and distress caused by the problem. There will also be a guided physical exam.
» Validated questionnaires.
They help to establish, as objectively as possible, the severity of the pathology and the effect it has on the individual.
» Laboratory study.
Lipid profile, blood sugar level, hormone profile, thyroid function, kidney and liver function, prostate pathology. It helps to establish associations and discover secondary cases of the disease.
» Urethral discharge.
It rules out the presence of urethritis, which can cause or aggravate the pathology.
