Premature ejaculation (PE) is a condition in which a man ejaculates earlier than he or his partner would like him to. The condition has significant heterogeneity with regards to classification and etiology.

Premature ejaculation can be differentiated between two types. Primary, which is present from the time a male begins puberty, and secondary, which is acquired later in a man's life. Premature ejaculation can be further divided between global premature ejaculation, which occurs with all partners and in all contexts, and situational premature ejaculation, which occurs in certain situations or with specific partners.

The causes of premature ejaculation are unclear. Risk factors for PE are shown in Pic. 1. Many theories have been suggested, including that PE was the result of masturbating quickly during adolescence to avoid being caught by an adult, of performance anxiety, of passive-aggressiveness, and having too little sex; but there is little evidence to support any of these theories.

However, PE is rarely caused by a physical problem (such as diabetes, high blood pressure, thyroid problems and prostate disease). In fact, evidence supports the notion that sexual control is actually a learned behavior that a man can relearn.

Idiopathic male infertility

Unexplained infertility is infertility that is idiopathic in the sense that its cause remains unknown even after an infertility work-up, usually including semen analysis in the man. Despite enormous progress in the understanding of human reproductive physiology, the underlying cause of male infertility remains undefined in about 50% of cases.

Men with premature ejaculation have no neurological reason for their dysfunction. These men could suffer the inability to climax during sexual stilmulace throughout their sexual life. Idiopathic premature ejaculation may be due to idiosyncratic patterns masturbation.

Ejaculatory disorders

Ejaculatory dysfunction, which includes a spectrum of disorders such as premature ejaculation, delayed ejaculation, anejaculation, painful ejaculation, retrograde ejaculation, and diminished volume or force of ejaculation, is an important public health problem that is often comorbid with erectile dysfunction and orgasmic dysfunction.

Ejaculatory and orgasm dysfunction are prevalent conditions and public health issues. Arousal, orgasm, and ejaculatory function are highly integrated and coordinated processes, and disorders in these categories often coexist.

It is estimated that 10-20% of men will have delayed ejaculation or an ejaculation, with 20-40% of men experiencing ejaculatory dysfunction at some point in their lives.
