What are the factors effecting premature ejaculation?
Psychological factors commonly contribute to premature ejaculation. While men sometimes underestimate the relationship between sexual performance and emotional well-being, premature ejaculation can be caused by temporary depression, stress over financial matters, unrealistic expectations about performance, a history of sexual repression, or an overall lack of confidence.
Interpersonal dynamics strongly contribute to sexual function, and premature ejaculation can be caused by a lack of communication between partners, hurt feelings, or unresolved conflicts that interfere with the ability to achieve emotional intimacy.
Neurological premature ejaculation can also lead to other forms of sexual dysfunction, or intensify the existing problem, by creating performance anxiety. In a less pathological context, premature ejaculation could also be simply caused by extreme arousal.
The neurotransmitor serotonin(5HT) has a central role in modulating ejaculation. Several animal studies have demonstrated its inhibitory effect on ejaculation modulated through the PGI system in the brain. Therefore, it is perceived that low level of serotonin in the synaptic cleft in these specific areas in the brain could cause premature ejaculation. This theory is further supported by the proven effectiveness of SSRIs, which increase serotonin level in the synapse in treating PE.
Sympathetic motor neurons control the emission phase of ejaculation reflex and expulsion phase is executed by somatic and autonomic motor neurons. These motor neurons are located in the thoracolumbar and lumbosacral spinal cord and are activated in a coordinated manner when sufficient sensory input to reach the ejaculatory threshold has entered the central nervous system.
Several areas in the brain, and especially the nucleus paragigantocellularis, have been identified to be involved in ejaculatory control.
Scientists have long suspected a genetic link to certain forms of premature ejaculation. In one study, ninety-one percent of men who suffered from lifelong premature ejaculation also had a first-relative with lifelong premature ejaculation.
Other researchers have noted that men who suffer from premature ejaculation have a faster neurological response in the pelvic muscles. Simple exercises commonly suggested by sex therapists can significantly improve ejaculatory control for men with premature ejaculation caused by neurological factors. Often, these men may benefit from anti-anxiety medication or selective serotonin reuptake inhibitors(SSRIs), such as sertraline or paroxetine, as these slow down ejaculation times. Some men prefer using anaesthetic creams, however, these creams may also deaden sensations in the man’s partner, and are not generally recommended by sex therapists.
