Orchitis presents acutely or chronically. Viral or bacterial infections cause acute orchitis, while autoimmune conditions and unknown causes lead to chronic forms, impacting fertility.

Area of Science:

  • Reproductive immunology
  • Urological pathology
  • Infectious diseases

Background:

  • Orchitis, testicular inflammation, manifests acutely (viral, bacterial) or chronically (autoimmune, idiopathic).
  • Acute orchitis often stems from viral infections or secondary bacterial epididymitis.
  • Chronic asymptomatic orchitis involves testicular immune cell infiltration, noted in 25% of azoospermia cases.

Purpose of the Study:

  • To review the diverse clinical presentations and potential etiopathogenesis of orchitis.
  • To highlight the significance of chronic asymptomatic orchitis in male infertility.
  • To underscore the potential utility of animal models in studying orchitis immunology and therapeutics.

Main Methods:

  • Literature review of orchitis classifications, causes, and clinical observations.
Keywords:

  • Discussion of immunological aspects and diagnostic findings, particularly in azoospermia.
  • Exploration of etiological hypotheses including infectious and autoimmune mechanisms.
  • Main Results:

    • Orchitis encompasses acute symptomatic (viral, bacterial) and chronic asymptomatic forms.
    • Chronic orchitis is characterized by testicular immune infiltrates, often linked to azoospermia.
    • The precise causes of chronic orchitis, especially autoimmune reactions, remain largely unelucidated.

    Conclusions:

    • Understanding orchitis requires differentiating acute and chronic presentations and their underlying causes.
    • Chronic asymptomatic orchitis represents a significant, yet poorly understood, factor in male infertility.
    • Further research, potentially utilizing animal models, is crucial for elucidating orchitis pathogenesis and developing treatments.
