Abstract

INTRODUCTION: This study presents a unifying concept of the pathophysiology of endometriosis and adenomyosis. In particular, a physiological model is proposed that provides a comprehensive explanation of the local production of estrogen at the level of ectopic endometrial lesions and the endometrium of women affected with the disease. METHODS: In women suffering from endometriosis and adenomyosis and in normal controls, a critical analysis of uterine morphology and function was performed using immunohistochemistry, MRI, hysterosalpingoscintigraphy, videohysterosonography, molecular biology as well as clinical aspects. The relevant molecular biologic aspects were compared to those of tissue injury and repair (TIAR) mechanisms reported in literature. RESULTS AND CONCLUSIONS: Circumstantial evidence suggests that endometriosis and adenomyosis are caused by trauma. In the spontaneously developing disease, chronic uterine peristaltic activity or phases of hyperperistalsis induce, at the endometrial-myometrial interface near the fundo-cornual raphe, microtraumatizations with the activation of the mechanism of 'tissue injury and repair' (TIAR). This results in the local production of estrogen. With ongoing peristaltic activity, such sites might increase and the increasingly produced estrogens interfere in a paracrine fashion with the ovarian control over uterine peristaltic activity, resulting in permanent hyperperistalsis and a self-perpetuation of the disease process. Overt auto-traumatization of the uterus with dislocation of fragments of basal endometrium into the peritoneal cavity and infiltration of basal endometrium into the depth of the myometrial wall ensues. In most cases of endometriosis/adenomyosis, a causal event early in the reproductive period of life must be postulated leading rapidly to uterine hyperperistalsis. In late premenopausal adenomyosis, such an event might not have occurred. However, as indicated by the high prevalence of the disease, it appears to be unavoidable that, with time, chronic normoperistalsis throughout the reproductive period of life leads to the same extent of microtraumatization. With the activation of the TIAR mechanism followed by infiltrative growth and chronic inflammation, endometriosis/adenomyosis of the younger woman and premenopausal adenomyosis share in principle the same pathophysiology. In conclusion, endometriosis and adenomyosis result from the physiological mechanism of 'tissue injury and repair' (TIAR) involving local estrogen production in an estrogen-sensitive environment normally controlled by the ovary.

Written from the paper’s full text.

TL;DR

The paper proposes that endometriosis and adenomyosis share a pathophysiology driven by uterine peristalsis-induced tissue injury and repair (TIAR), with local estrogen production causing self-perpetuating hyperperistalsis and auto-traumatization. It integrates prior morphological, imaging, molecular, and clinical evidence into a unifying model rather than reporting a new primary study.

Key findings

  • Endometriosis and adenomyosis are proposed to result from trauma: chronic uterine peristaltic activity or hyperperistalsis induces microtraumatization at the endometrial–myometrial interface near the fundo-cornual raphe, activating TIAR and local estrogen production.
  • Locally produced estrogen acts in a paracrine fashion on the archimyometrium, interfering with ovarian control of uterine peristalsis, leading to permanent hyperperistalsis and self-perpetuation; overt auto-traumatization then dislocates basal endometrium into the peritoneal cavity and infiltrates the myometrium.
  • Iatrogenic uterine trauma (e.g., hysterotomy, curettage) may act as a strong one-time “first-step” injury; in rhesus monkeys, a history of estrogen patches plus hysterotomy trauma showed a significant association with endometriosis.
  • The basal endometrium in women with endometriosis is twice as thick as in healthy women; ER and PR expression declined in the functionalis and rose in the basalis and endometriotic lesions across the secretory phase, suggesting physiological progesterone resistance in basal/ectopic tissue rather than generalized progesterone resistance.

Methods

  • Narrative review/model synthesis: critical analysis of uterine morphology and function in women with endometriosis and adenomyosis and in normal controls using immunohistochemistry, MRI, hysterosalpingoscintigraphy, videohysterosonography, molecular biology, and clinical aspects.
  • Relevant molecular biologic aspects were compared with tissue injury and repair (TIAR) mechanisms reported in the literature.
  • No new primary cohort or trial is described; evidence is drawn from prior studies and clinical/experimental observations.

Limitations

  • Not stated in the paper: no formal limitations section.
  • Evident from the text: conclusions are based on “circumstantial evidence” and a proposed unifying model; causal mechanisms are inferred rather than prospectively tested.
  • Evident from the text: this is a narrative synthesis without systematic search or quantitative meta-analysis, and some elements are explicitly speculative (e.g., “tempting to speculate” about cycle irregularities).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
