Analysis of the relationship between prostatitis and erectile dysfunction, premature ejaculation, and fertility

Is chronic prostatitis the same as erectile dysfunction or premature ejaculation? Why do some patients with chronic prostatitis experience erectile dysfunction?

Many medical and pharmaceutical advertisements often feature phrases like, "Having prostatitis will lead to impotence and premature ejaculation." With the relentless promotion by "specialist hospitals," this has become an accepted truth. At this point, you might realize that the claim that "chronic prostatitis is equivalent to impotence and premature ejaculation" is actually a marketing tactic employed by businesses, and a very successful one at that.

Indeed, the impact of chronic prostatitis on men's health is receiving increasing attention. Erectile dysfunction and premature ejaculation are common among prostatitis patients, but in most cases, these are simply coincidental occurrences and not directly caused by prostatitis. As you already know, penile erection is related to anatomy, the nervous system, the vascular system, and the endocrine system, and prostatitis does not directly affect any of these systems, therefore it does not directly impair male erectile function. As for premature ejaculation, only a small percentage of secondary premature ejaculation cases are related to prostatitis.

Why do some men with chronic prostatitis experience erectile dysfunction? This is mainly due to psychological reasons. Men with chronic prostatitis are prone to varying degrees of anxiety and depression, and anxiety and depression are the most common emotional problems leading to sexual dysfunction. Studies have found a correlation between anxiety levels and prostatitis symptoms; the higher the level of education, the higher the anxiety level. Furthermore, some men may experience sexual repression and avoidance due to the misconception that prostatitis is a sexually transmitted disease, worrying about infecting their wives or passing it on to their offspring, or fearing that chronic prostatitis is incurable.

In addition, men with chronic prostatitis may experience pain during ejaculation or scrotal and testicular pain, which may worsen after intercourse and affect their libido. Furthermore, a small percentage of men with prostatitis may experience premature ejaculation. Combined with their partner's poor satisfaction with sex, these factors can create psychological stress for men, affecting libido and erectile function, further exacerbating worry and anxiety, creating a vicious cycle, gradually leading to aversion and fear of sex, and ultimately impacting sexual function.

In short, the patient's decreased sexual function is not caused by a disease of the prostate itself, but by other organic or psychological reasons. If men with erectile dysfunction blindly treat it as prostatitis, it can easily cause unnecessary damage, resulting not only in the failure to cure erectile dysfunction but also potentially exacerbating the prostatitis.

Does prostatitis affect fertility?

Patients often say, "I've been married for many years, and my wife hasn't gotten pregnant. A semen analysis revealed a problem. The doctor ordered a prostate fluid test, saying I have chronic prostatitis. We've been treating the prostatitis for a long time, but my wife still hasn't conceived. What should I do?" Actually, this view that "prostatitis affects fertility, and treating infertility means treating prostatitis" is completely wrong and intentionally or unintentionally misleading. It's true that, superficially, prostate fluid is an important component of semen, the prostate is related to fertility, and long-term chronic inflammation can change the composition of prostate fluid, potentially affecting semen quality. However, there are many causes of infertility, and chronic prostatitis is by no means the most important one.

We already know that sperm are produced in the testes and mature in the epididymis, so the prostate has nothing to do with sperm production. Therefore, abnormal sperm density (such as azoospermia or oligospermia) is unrelated to the prostate.

The prostate gland participates in the liquefaction process of semen, producing enzymes that help liquefy it. Inflammation of the prostate can impair the secretion of these enzymes, leading to semen non-liquefaction. In other words, prostatitis can cause semen non-liquefaction, but abnormalities in the seminal vesicles can also cause it. Therefore, not all cases of semen non-liquefaction are caused by prostatitis.

So, is asthenospermia (poor sperm motility) related to prostatitis? Normal prostatic fluid has a pH of 6.5, which may rise to 7-8 during inflammation. Simultaneously, the levels of zinc and citric acid decrease, reducing the activity of related enzymes and potentially affecting sperm motility. However, sperm only mix with prostatic fluid after ejaculation, and because the time they spend together is short, the impact of prostatic fluid on sperm motility is relatively small. Furthermore, many factors affect sperm motility, and it cannot be explained solely by an abnormality in prostatic fluid. Therefore, asthenospermia, especially severe asthenospermia, is not strongly related to prostatitis.

In conclusion, while a small percentage of male infertility is indeed related to prostatitis, it is not the most significant contributing factor. Treatments that target prostatitis as the sole cause will not yield ideal results. Conversely, some medical institutions now offer various physical therapy methods for treating chronic prostatitis, such as interventional procedures, conductive ablation, intracavitary therapy, and prostate injections. These methods are based on thermotherapy, which can harm the spermatogenic function of the testes. Therefore, men who have not yet fathered children should use these treatments with caution.
