Probably you have heard the term premature ejaculation or PE in some contexts other. Ejaculation means the outcome of sexual arousal and it happens simultaneously with orgasm. It may happen within 4 to 10 minutes after arousal and erection. This process of ejaculation a generally controlled by central nervous system and it is primarily a neurobiological phenomenon. With the help of a large number of neurotransmitters in the brain and spinal cord regulates the ejaculation process. The neurotransmitters important for this process include serotonin, dopamine, oxytocin and others. According to scientific studies, serotonin and specifically 5-HT receptors are responsible for activating this process.
In case of premature ejaculation or PE, something else happens in this process. The normal male sexual response is described as a sequence of phases which include four stages such as sexual desire, arousal, ejaculation or orgasm and resolution. The problem with the sexual function happens in one or more of the three first stages of this sexual response cycle. Such sexual dysfunction may include dysfunctions of sexual desire (e.g. hypoactive sexual desire), arousal (e.g. erectile dysfunction) and orgasm/ejaculation (e.g. premature ejaculation, retarded ejaculation or inability to ejaculate).
PE happens because of the rapid evolution of the first two stages of the sexual response cycle. It is a neurobiological problem which is generally linked to low serotonin levels in the central nervous system which is responsible for regulation of ejaculation.
Features of PE
PE or premature ejaculation is the most common type of sexual dysfunction in men below 60 years. People who suffer from this problem are forced to complete the sexual acts within 1 to 2 minutes after penetration as ejaculation occurs too fast and there is no control over the process. In this case, the phase of sexual arousal is too short where the person can achieve erection at a faster rate but ejaculation and orgasm happens rapidly. As a result of the other men cannot enjoy sexual intercourse.
The following are some of the common features of premature ejaculation-
Ejaculation always or almost always occurs before or within one minute after penetration of the penis into the vagina.
No control over ejaculation- after vaginal penetration, the person is not able to delay ejaculation.
Negative personal consequences and feelings– people who suffer from this problem also suffer from anxiety and disappointment and as a result of that they may try to avoid sexual and emotional intimacy.
One minute is crucial here because according to large epidemiological studies, 90% of men with PE reported to reach ejaculation within one minute from penetration. Short intercourse duration is a parameter that shows whether the person is capable of controlling ejaculation. However it does not measure the sexual satisfaction and disappointment because of this problem.
Types of Premature Ejaculation
There are two types of PE seen and the first one is the most common PE problem seen in case of men.
Primary PE- this is also called as chronic or lifelong PE. In this case the person has been experiencing PE from his very first sexual experience. In such cases ejaculation happens before vaginal penetration or within less than 1 to 2 minutes after penetration.
Secondary PE- it is also known as acquired PE. It can happen suddenly or gradually. Before this the person concerned may have been able to enjoy the sexual intercourse.
