What other factors may affect how long a man lasts in bed?
Possible biochemical factors affecting premature ejaculation include testosterone, the male hormone which is thought to play a role in men’s ejaculatory reflex. Higher free testosterone levels occur in men with premature ejaculation. Another factor which may influence how along a man can last during sex are the biochemical parameters of the prostate and epididymis, because research in a Chinese andrology journal seemed to show that semen from men who lacked the ability to last longer during sex contained significantly less acid phosphatase and alpha-glucosidase than semen from other men.
And many men with premature ejaculation have low serum levels of prolactin; although in one study, men in the lowest quartile of serum prolactin levels also had some linked metabolic syndrome, together with erectile dysfunction, and higher than average levels of anxiety. So while prolactin may contribute to premature ejaculation, the presence of anxiety in many men with PE suggests that biochemical factors play only a minor (if any) role in the genesis of premature ejaculation.
While other factors may affect how to last longer during sex, we do know that psychological factors greatly influence premature ejaculation.
Men with premature ejaculation have much lower intravaginal ejaculatory latency time or IELT (obviously) – it just means they cannot last very long in bed - but a shorter IELT is not the only measure of premature ejaculation. In fact, perception of ejaculation control changes both partners’ sexual satisfaction or distress, regardless of how long a man can last during sex.
So while premature ejaculation is perhaps not entirely a psychological issue, such factors do indicate a massive psychological role. Men who wish to learn how to last longer during sex need to accept that the work starts with their minds….
