Chronic prostatitis is associated with poorer semen quality in men

A 2023 literature review reports poorer semen quality in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Across pooled studies, CP/CPPS was associated with lower sperm concentration and progressive motility. The 2017 meta-analysis covered 27 studies and 3241 participants.

Key Findings

  • A 2017 systematic review and meta-analysis of 27 studies with 3241 participants found CP/CPPS associated with lower progressive motility, sperm concentration and normal morphology, and with reduced semen volume.
  • A 2016 systematic review and meta-analysis compared 721 patients with CP/CPPS against 160 controls across six studies and found higher antisperm antibody levels in the patients.
  • Male accessory gland infection or inflammation (MAGI) occurred in 2 to 18% of infertile patients, depending on the diagnostic criteria used.
  • Reported prevalence of HPV in semen runs from 2 to 31% among men in the general population and from 10 to 35.7% among infertile men.
  • Proposed links between CP/CPPS and infertility include male accessory gland inflammation, metabolic syndrome, irritable bowel syndrome, HPV co-infection and autoimmunity.

Interpretation

The paper is a literature review that summarizes earlier clinical studies, systematic reviews and meta-analyses. Its own search selected 11 studies published from January 2012 to December 2022, out of 607 results. The authors state that a certain connection between the two conditions has not been found yet, and they present the mechanisms as proposed. The review did not consider treatment of CP/CPPS in men with semen alterations or infertility.

RRM Context

The review states that a male factor accounts for about 30% of infertility cases by itself and for a further 20% as a contributing cause. Restorative reproductive medicine evaluates both partners and seeks the cause of low fertility. The review lists gland inflammation, metabolic syndrome and autoimmunity among the proposed links between CP/CPPS and infertility. The authors advise a team approach for men with CP/CPPS who want a pregnancy.

Abstract

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is defined as urologic pain or discomfort in the pelvic region, associated with urinary symptoms and/or sexual dysfunction, lasting for at least 3 of the previous 6 months. The rate of symptoms related to prostatitis has a mean prevalence of 8-8.2%. CP/CPPS is most frequent in men younger than 50 years, among whom it is the most common urologic diagnosis. In the last decades, many studies have been published on CP/CPPS and its association with male infertility. The pathophysiologic relation between CP/CPPS and male infertility involves several aspects, which are not well studied yet. A reduction in semen parameters has been demonstrated in patients with CP/CPPS, and several mechanisms have been proposed to represent putative pathophysiological links between CP/CPPS and infertility, including male accessory gland inflammation, metabolic syndrome, inflammatory bowel disease, HPV co-infection and autoimmunity. In light of this evidence, a multidisciplinary approach is advocated for patients with known CP/CPPS, and particular attention is needed for male patients of infertile couples in order to evaluate male accessory glands correctly. In addition, it is advisable that future studies dealing with the treatment of CP/CPPS take into consideration all the different pathophysiological aspects implicated.
