Among a number of problems related with the sexual health of many men and of course his partner, we find Premature Ejaculation as the most common sexual problem occurring to a great number of men around the world; this is a pathology characterized by a lack of voluntary control over ejaculation. Masters and Johnson stated that a man suffers from premature ejaculation if he ejaculates before his partner achieves orgasm in more than fifty percent of his sexual encounters. Other sex researchers have defined premature ejaculation as occurring if the man ejaculates within two minutes of penetration; however, a survey by Alfred Kinsey, (yes the inquisitive scientist of the movie that recently showed at theaters) made in the 1950s demonstrated that three quarters of men ejaculated within two minutes of penetration in over half of their sexual encounters, so there is not a precise timing we can use to define a premature ejaculator.
Today, most sex therapists understand premature ejaculation as occurring when a lack of ejaculatory control interferes with sexual or emotional well-being in one or both partners. And it is known that about thirty percent of men suffer from premature ejaculation on a consistent basis.
Premature Ejaculation is believed to be a psychological problem and does not represent any known organic disease involving the male reproductive tract or any known lesions in the brain or nervous system. In short, PE is not a physiological problem or disease, though it manifests physiologically by considering the organ systems directly affected by PE, that include the male reproductive tract (i.e., penis, prostate, seminal vesicles, testicles, and their appendages), the portions of the central and peripheral nervous system controlling the male reproductive tract, and the reproductive organ systems of the sexual partner (for the purpose of this discussion, the partner is assumed to be female) that may not be stimulated sufficiently to achieve orgasm.
If the PE occurs so early that it happens before commencement of sexual intercourse and the couple is attempting pregnancy, then pregnancy is impossible to achieve unless artificial insemination is used. Perhaps the most affected organ system is the psyche of the partners. Both partners are likely to be dissatisfied emotionally and physically by this problem and it can put great stress on the relation.
The statistics of the premature ejaculation condition are as follows:
Frequency: In the US the prevalence rate of PE in American males is estimated to range from 30-70%.
Internationally: Estimates for European countries and India mirror the prevalence in the United States. The prevalence in other parts of Asia, Africa, Australia, and elsewhere is unknown.
Mortality/Morbidity: No known direct morbidity or mortality results from premature ejaculation.
Race: No reproducible data exist on major differences between racial groups with respect to the incidence or prevalence of PE.
Sex: PE is a condition that only affects males.
Age: Premature Ejaculation can occur at virtually any age in an adult man's life but it's most common in younger men (aged 18-30), than in older males (45-60).
