What is premature ejaculation?

Rapid ejaculation is most common type of sexual dysfunction, which affects men younger than 40 years. According to majority of doctors dealing with this problem, premature ejaculation is condition in which ejaculation occurs before it`s desired by both sexual partners. This definition allows you to avoid clear time frame, how long sexual intercourse should last, giving you opportunity to consider time of ejaculation as individual feature.

In those cases where premature ejaculation occurs occasionally, don`t take it as dysfunction. If premature ejaculation occurs in more than 50% of cases of sexual intercourse, we can talk about already existing problem.  In order to clarify meaning of this definition of premature ejaculation, you can give example: if man during sexual intercourse reaches its peak within eight minutes, and partner within five minutes, both remain satisfied.

In another case, man may delay ejaculation time up to twenty minutes, but his partner needs 35 minutes to set orgasm. Naturally, in the last example, partner’s satisfaction wouldn`t be achieved, but in this case it is impossible to speak of early ejaculation.

Since many women are incapable of vaginal orgasm, no matter how long sexual intercourse lasts, last example most likely demonstrates slowed orgasm in woman than premature ejaculation in a man. Thus, concept of rapid ejaculation depends on point of view of partners.

Features of manifestation

Premature ejaculation has the following manifestations:

  • Persistent ejaculation with little sexual stimulation before or immediately after start of sexual intercourse.
  • Psychological suffering or difficulties in relationship of sexual partners, with ejaculation can occur.

Sexual response in humans can be divided into 3 phases – desire (libido), arousal and orgasm. We divide sexual dysfunctions into four categories:

  • Primary.
  • Related to common diseases.
  • Caused by objective circumstances.
  • Nonspecific.

Each of these categories of sexual disorders in men affects all three phases of sexual response.

Classification of premature ejaculation

There are primary and secondary violations. In initial form of rapid ejaculation, man begins to experience violation before age when sexual activity begins.

In secondary form, rapid ejaculation develops after man has already experienced normal sexual relationships with controlled ejaculation.  Most often, secondary form occurs as nonspecific, not associated with any objective circumstances.

Currently, it`s believed that this form of premature ejaculation is in most cases associated with mental disorders.

Pathophysiology of premature ejaculation

Premature ejaculation is considered psychological problem, so for men there are no structural changes in organs involved in sexual life, as well as in central and peripheral nervous system. Organs and systems involved in rapid ejaculation include penis, testicles, epididymis, vas deferens, central and peripheral nervous system, and female organs of genitals.

In cases where premature ejaculation happens even before start of intercourse, fertilization becomes problematic and one has to resort to artificial insemination.

From point of evolution, rapid ejaculation is favorable factor. Since this is achieved fertilization in shortest possible time. After all, sexual intercourse itself is act that puts man in potentially defenseless position and at this time he can be killed or rejected by enemy. Thus, genes are responsible for rapid ejaculation in terms of procreation are useful.

For a long time, premature ejaculation was considered to be psychologically determined, originating in subconscious reinforcement of behavioral stereotype as soon as possible to complete sexual intercourse because of fear of being caught during masturbation in youth. With adulthood, such stereotype becomes persistent and very formidable.

Latest research still contributes to understanding of development of early ejaculation as result of disturbances in nervous system. It is known that ejaculation is controlled by nerves originating in lumbar spinal cord, which in turn are controlled by overlying structures of brain that use dopamine to transmit nerve impulses.
