Molecular Targets for Nonhormonal Treatment Based on a Multistep Process of Adenomyosis Development. Reprod Sci 2023; 30:743-760. [PMID: 35838920 DOI: 10.1007/s43032-022-01036-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Accepted: 07/09/2022] [Indexed: 10/17/2022]
Abstract
Adenomyosis is an estrogen-dependent gynecologic disease characterized by the presence of endometrial tissue within the myometrium. Adenomyosis presents with abnormal uterine bleeding, pelvic pains, and infertility. This review aimed to investigate the major estrogen downstream effectors involved in the process of adenomyosis development and their potential use for nonhormonal treatment. A literature search was performed for preclinical and clinical studies published between January 2010 and November 2021 in the PubMed and Google Scholar databases using a combination of specific terms. Adenomyosis presents with a wide spectrum of clinical manifestations from asymptomatic to severe through a complex process involving a series of molecular changes associated with inflammation, invasion, angiogenesis, and fibrosis. Adenomyosis may develop through a multistep process, including the acquisition of (epi)genetic mutations, tissue injury caused at the endometrial-myometrial interface, inside-to-outside invasion (from the endometrial side into the uterine wall), or outside-to-inside invasion (from the serosal side into the uterine wall), and epithelial-mesenchymal transition, tissue repair or remodeling in the myometrium. These processes can be regulated by increased estrogen biosynthesis and progesterone resistance. The expression of estrogen downstream effectors associated with persistent inflammation, fragile and more permeable vessel formation, and tissue injury and remodeling may be correlated with dysmenorrhea, heavy menstrual bleeding, and infertility, respectively. Key estrogen downstream targets (e.g., WNT/β-catenin, transforming growth factor-β, and nuclear factor-κB) may serve as hub genes. We reviewed the molecular mechanisms underlying the development of adenomyosis and summarized potential nonhormonal therapies.

Abstract
In brief Traditionally viewed as enigmatic and elusive, adenomyosis is a fairly common gynecological disease but is under-recognized and under-researched. This review summarizes the latest development on the pathogenesis and pathophysiology of adenomyosis, which have important implications for imaging diagnosis of the disease and for the development of non-hormonal therapeutics. Abstract Traditionally considered as an enigmatic disease, adenomyosis is a uterine disease that affects many women of reproductive age and is a contributing factor for pelvic pain, heavy menstrual bleeding (HMB), and subfertility. In this review, the new development in the pathogenesis and pathophysiology of adenomyosis has been summarized, along with their clinical implications. After reviewing the progress in our understanding of the pathogenesis and describing the prevailing theories, in conjunction with their deficiencies, a new hypothesis, called endometrial-myometrial interface disruption (EMID), which is backed by extensive epidemiologic data and demonstrated by a mouse model, is reviewed, along with recent data implicating the role of Schwann cells in the EMI area in the genesis of adenomyosis. Additionally, the natural history of adenomyotic lesions is elaborated and underscores that, in essence, adenomyotic lesions are fundamentally wounds undergoing repeated tissue injury and repair (ReTIAR), which progress to fibrosis through epithelial-mesenchymal transition, fibroblast-to-myofibroblast transdifferentiation, and smooth muscle metaplasia. Increasing lesional fibrosis propagates into the neighboring EMI and endometrium. The increased endometrial fibrosis, with ensuing greater tissue stiffness, results in attenuated prostaglandin E2, hypoxia signaling and glycolysis, impairing endometrial repair and causing HMB. Compared with adenomyosis-associated HMB, the mechanisms underlying adenomyosis-associated pain are less understood but presumably involve increased uterine contractility, hyperinnervation, increased lesional production of pain mediators, and central sensitization. Viewed through the prism of ReTIAR, a new imaging technique can be used to diagnose adenomyosis more accurately and informatively and possibly help to choose the best treatment modality.

The Role of Abnormal Uterine Junction Zone in the Occurrence and Development of Adenomyosis. Reprod Sci 2021; 29:2719-2730. [PMID: 34515984 DOI: 10.1007/s43032-021-00684-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 06/28/2021] [Indexed: 02/06/2023]
Abstract
Adenomyosis is a benign disease with a malignant behavior, bothering a lot of women at reproductive age who suffer from increased menstruation, prolonged menstruation, progressive dysmenorrhea, and infertility. At present, there is no effective treatment for adenomyosis. It seriously affects the life quality of these patients. However, the pathogenesis of adenomyosis is not yet clear. Recently, uterus junctional zone, defined as the inner 1/3 of myometrium between endometrium and myometrium, has gained broad attention. As is reported, the structure and function disorder of uterus junctional zone may play an important part in the occurrence and development of adenomyosis. In this issue, the present study generally reviews the role of uterine junction zone and the related mechanisms involved in adenomyosis, such as the local micro-damage, the formation of inflammatory and hypoxic microenvironment, changes of cytokines, and abnormalities of miRNA as well as signal pathways. It will provide new insights and potential therapeutic target strategies for clinical strategies in the management of adenomyosis.

Inflammatory Mediators and Pain in Endometriosis: A Systematic Review. Biomedicines 2021; 9:biomedicines9010054. [PMID: 33435569 PMCID: PMC7826862 DOI: 10.3390/biomedicines9010054] [Citation(s) in RCA: 54] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 01/01/2021] [Accepted: 01/03/2021] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND pain is one of the main symptoms of endometriosis and it has a deleterious effect on a patients' personal and social life. To date, the clinical management of pain includes prolonged medication use and, in some cases, surgery, both of which are disruptive events for patients. Hence, there is an urgency for the development of a sufficient non-invasive medical treatment. Inflammation is one of the causative factors of pain in endometriosis. It is well established that inflammatory mediators promote angiogenesis and interact with the sensory neurons inducing the pain signal; the threshold of pain varies and it depends on the state and location of the disease. The inhibition of inflammatory mediators' synthesis might offer a novel and effective treatment of the pain that is caused by inflammation in endometriosis. OBJECTIVES patients with endometriosis experience chronic pelvic pain, which is moderate to severe in terms of intensity. The objective of this systematic review is to highlight the inflammatory mediators that contribute to the induction of pain in endometriosis and present their biological mechanism of action. In addition, the authors aim to identify new targets for the development of novel treatments for chronic pelvic pain in patients with endometriosis. DATA SOURCES three databases (PubMed, Scopus, and Europe PMC) were searched in order to retrieve articles with the keywords 'inflammation, pain, and endometriosis' between the review period of 1 January 2016 to 31 December 2020. This review has been registered with PROSPERO (registry number: CRD42020171018). Eligibility Criteria: only original articles that presented the regulation of inflammatory mediators and related biological molecules in endometriosis and their contribution in the stimulation of pain signal were included. DATA EXTRACTION two authors independently extracted data from articles, using predefined criteria. RESULTS the database search yielded 1871 articles, which were narrowed down to 56 relevant articles of interest according to the eligibility criteria. CONCLUSIONS inflammatory factors that promote angiogenesis and neuroangiogenesis are promising targets for the treatment of inflammatory pain in endometriosis. Specifically, CXC chemokine family, chemokine fractalkine, and PGE2 have an active role in the induction of pain. Additionally, IL-1β appears to be the primary interleukin (IL), which stimulates the majority of the inflammatory factors that contribute to neuroangiogenesis along with IL-6. Finally, the role of Ninj1 and BDNF proteins needs further investigation.

Abstract
Nerve growth factor (NGF) has been verified to be expressed with higher level in adenomyosis uteri, and its neutralizing antibody has a strong inhibitory influence on inflammation. The present study aimed to explore the effect of anti-NGF on the expression of proteins in uteri of mice-induced adenomyosis and assessed its potential role in improving pregnancy rate. In this study, we established a mouse model of adenomyosis and administrated NGF-neutralizing antibody into mice. The mass spectrometry (MS) analysis of the uteri during the implantation window was performed to explore the essential proteins participating in therapy. Besides, embryos of healthy mice were transferred into the uteri to assess the implantation rate. The results of MS analysis demonstrated that 119 proteins were changed in the adenomyosis group compared with control group, and 126 proteins were differentially expressed in the anti-NGF group compared with the adenomyosis group (fold change > 1.5, P < 0.05. After performing cluster analysis using Mfuzz package, we found that a group of proteins participated in cell-cell adhesion and metabolic processes, which were attenuated in the adenomyosis group, while those were successfully recovered by anti-NGF treatment. Western blotting confirmed that the expression levels of integrin alpha-1 (ITGA1), integrin beta-1 (ITGB1), laminin subunit gamma-1 (LAMC1), and creatine kinase M-type (CKM) were decreased in adenomyosis group, whereas those levels were elevated after anti-NGF treatment. Embryo implantation rate in the adenomyosis group was significantly decreased compared with that in the control group (2.31% vs. 26.15%, P < 0.001) and anti-NGF treatment slightly enhanced the embryo implantation rate in mice with experimentally induced adenomyosis (9.23% vs. 2.31%, P = 0.017). Our results revealed that anti-NGF therapy can improve fertility of mice with experimentally induced adenomyosis, possibly through promoting integrin-related proteins.

Abstract
BACKGROUND Adenomyosis is a benign gynecological disorder associated with subfertility, pelvic pain and abnormal uterine bleeding that have significant consequences for the health and quality of life of women. Histologically, it is defined as the presence of ectopic endometrial islets within the myometrium. Its pathogenesis has not yet been elucidated and several pieces of the puzzle are still missing. One process involved in the development of adenomyosis is the increased capacity of some endometrial cells to infiltrate the myometrium. Moreover, the local and systemic immune systems are associated with the onset of the disease and with maintaining it. Numerous observations have highlighted the activation of immune cells and the release of immune soluble factors in adenomyosis. The contribution of immunity occurs in conjunction with hormonal aberrations and activation of the epithelial to mesenchymal transition (EMT) pathway, which promotes migration of endometrial cells. Here, we review current knowledge on the immunological changes in adenomyosis, with the aim of further elucidation of the pathogenesis of this disease. OBJECTIVE AND RATIONALE The objective was to systematically review the literature regarding the role of the immune system in development of adenomyosis in the inner and the outer myometrium, in humans. SEARCH METHODS A systematic review of published human studies was performed in MEDLINE, EMBASE and Cochrane Library databases from 1970 to February 2019 using the combination of Medical Subject Headings (MeSH): Adenomyosis AND ('Immune System' OR 'Gonadal Steroid Hormones'), and free-text terms for the following search terms (and their variants): Adenomyosis AND (immunity OR immune OR macrophage OR 'natural killer cell' OR lymphocyte* OR leucocyte* OR HLA OR inflammation OR 'sex steroid' OR 'epithelial to mesenchymal transition' OR 'EMT'). Studies in which no comparison was made with control patients, without adenomyosis (systemic sample and/or eutopic endometrium), were excluded. OUTCOMES A total of 42 articles were included in our systematic review. Changes in innate and adaptive immune cell numbers were described in the eutopic and/or ectopic endometrium of women with adenomyosis compared to disease-free counterparts. They mostly described an increase in lymphocyte and macrophage cell populations in adenomyosis eutopic endometrium compared to controls. These observations underscore the immune contributions to the disease pathogenesis. Thirty-one cytokines and other markers involved in immune pathways were studied in the included articles. Pro-inflammatory cytokines (interleukin (IL) 6, IL1β, interferon (IFN) α, tumor necrosis factor α, IFNγ) as well as anti-inflammatory or regulatory mediators (IL10, transforming growth factor β…) were found to be elevated in the eutopic endometrium and/or in the ectopic endometrium of the myometrium in women with adenomyosis compared to controls. Moreover, in women affected by adenomyosis, immunity was reported to be directly or indirectly linked to sex steroid hormone aberrations (notably changes in progesterone receptor in eutopic and ectopic endometrium) in three studies and to EMT in four studies. WIDER IMPLICATIONS The available literature clearly depicts immunological changes that are associated with adenomyosis. Both systemic and local immune changes have been described in women affected by adenomyosis, with the coexistence of changes in inflammatory as well as anti-inflammatory signals. It is likely that these immune changes, through an EMT mechanism, stimulate the migration of endometrial cells into the myometrium that, together with an endocrine imbalance, promote this inflammatory process. In light of the considerable impact of adenomyosis on women's health, a better understanding of the role played by the immune system in adenomyosis is likely to yield new research opportunities to better understand its pathogenesis.

Abstract
STUDY QUESTION Are selective markers for the neuronal differentiation such as microtubule-associated protein 2 (MAP-2) and synaptophysin (SYP) as well as the nerve growth factor (NGF) expressed by fibroids, myometrium and eutopic endometrium? SUMMARY ANSWER Neuronal markers NGF, MAP-2 and SYP are highly expressed in fibroids compared with matched myometrium, and this neurogenic pathway is upregulated by tumor necrosis factor (TNF) alpha in cultured smooth muscle cells (SMCs). WHAT IS KNOWN ALREADY Uterine fibroids or leiomyomas are the most common benign tumors, accounting for approximately one-third of hysterectomies. The present trend is to improve the medical treatment avoiding surgery, also for fertility sparing; hence, the pathogenic mechanisms are investigated, aiming to develop new therapeutic strategy. STUDY DESIGN, SIZE, DURATION This laboratory-based case-control study is focused on fibroids and myometrial specimens obtained between 2015 and 2017 from 15 women of reproductive age at the proliferative phase of the menstrual cycle. Leiomyomas, matched myometrium and endometrium from each woman were analyzed. Control endometrium was obtained from women undergoing surgery for ovarian cyst (n = 15). PARTICIPANTS/MATERIALS, SETTING, METHODS qRT-PCR, western blotting and immunostaining were applied to evaluate the expression of neurogenic markers; the effects of TNF on NGF, MAP-2 and SYP expression in cultured SMCs from leiomyomas and matched myometrium were analyzed. MAIN RESULTS AND THE ROLE OF CHANCE qRT-PCR analyses using tissues from clinical patients showed that the levels of NGF, MAP-2 and SYP mRNA were significantly higher in uterine leiomyomas compared with their matched myometrium (P < 0.05), whereas only NGF was significantly increased in eutopic endometrium compared with healthy endometrium. In primary SMCs, isolated from fibroids or from the adjacent myometrium, NGF, MAP-2 and SYP mRNA expression were significantly increased by TNF treatment (P < 0.05). Finally, human endometrial stromal cells prepared from the endometrium of patients affected by uterine fibroids display higher TNF expression (P < 0.001). LIMITATIONS, REASONS FOR CAUTION qRT-PCR analysis and immunofluorescence validation are robust methods demonstrating a clear upregulation of neurogenic factors in leiomyomas, even though additional studies are needed to establish a correlation between increased neuronal gene expression and degree of pain, as well as the involvement of inflammation mediators in the development of the neurogenic unhinge. Therefore, more in vivo studies are needed to confirm the results achieved from primary cultured SMCs. WIDER IMPLICATIONS OF THE FINDINGS The increased expression of neurogenic factors in uterine fibroids and endometrium may contribute to explain the painful stimuli. Accordingly, these neurogenic pathways may represent potential therapeutic avenues to treat the fibroid-related disorders. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by research grants from the University of Siena. The authors declare no conflict of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE to identify novel biomarkers for peritoneal endometriosis in eutopic endometrium thus giving an oportunity for non-invasive diagnosis. DESIGN A cross-sectional single-center study SETTING: tertiary care hospital PATIENTS: 49 patients subjected to laparoscopy because of suspected endometriosis, 33 patients out of the group qualified to the study had sufficient endometrial tissue taken and were in their follicular phase of menstrual cycle. INTERVENTIONS biopsy sampling of eutopic endometrial tissue during diagnostic or diagnostic and terapeutic laparoscopy, questionaires, MAIN OUTCOME MEASURE(S): qRT-PCR to evaluate the mRNA expression of selected candidate marker genes in endometrium: ARO1 (aromatase), CXCL8 (interleukin 8), NGF (nerve growth factor), VEGF-A (vascular endothelial growth factor A), PDGF-A (platelet-derived growth factor A). RESULTS mRNA expression of ARO1, CXCL8, VEGF-A and PDGF-A did not differ significantly between women with and without endometriosis. NGF mRNA expression was decreased in women with endometriosis. CONCLUSIONS Observed preliminary results suggest a possible role of NGF in early diagnosis of peritoneal endometriosis. The role of NGF changes in eutopic endometrium of patients with peritoneal endometriosis needs further evaluation.

Abstract
OBJECTIVE The aim of the study was to expand the understanding of pathogenesis of adenomyosis-associated pelvic pain. MATERIAL AND METHODS We studied 30 (n = 30) biopsy samples obtained after hysterectomy in women with diffuse adenomyosis of grade II-III, accompanied by severe pain syndrome, who did not receive hormonal therapy. The morphologic comparison group comprised 30 (n = 30) biopsy samples obtained from women with adenomyosis, without pain syndrome, operated on for abnormal uterine bleeding, who also did not receive hormone therapy. RESULTS The total density of immunological OTR labeling in the adenomyotic lesion foci was 73.7 ± 1.8%, and in the morphological control group it was 35.2 ± 1.4% (p <0.05), which indicates a significant effect of oxytocin as a ureterotonic peptide. Processes of local neurogenesis and growth of nerve fibers was established due to an increase in the expression of the nervous system growth factor NGF in the myometrium stroma, in comparison with biopsy samples of morphological control. UNLABELLED Conclusion: Pelvic pain pathogenesis in women with diffuse adenomyosis compared with the painless form of the disease is an increase in the activity of ureterotonic factors of OTR oxytocin. Compared to the painless form of adenomyosis, the myometrial innervation apparatus of patients with pelvic pain is characterized by a significantly higher expression of nerve growth factor.

Abstract
Adenomyosis, which manifests with focally or diffusely scattered endometrial tissue within the uterine myometrium, is an endometriosis-like disease with controversial pathogenesis and compromised reproductive outcomes. This review, including the in vitro and in vivo studies performed on human or mouse models, is aimed to summarize the specific molecular characteristics of endometrium in the biochemical microenvironments of uterine adenomyosis. Many studies attributed the endometrium as the main cause of pathogenesis, with evidence of differential genetic expression and/or epigenetic modulation as well as estrogen-induced epithelial-mesenchymal transition. However, some studies indicated that the myometrium could play a role in the development of disease, based on findings of smooth muscle metaplasia and/or fibroblast-to-myofibroblast transdifferentiation by the influence of local biochemical factors. To date, it remains unclear whether adenomyosis is a genetically determined or a microenvironmentally induced disorder or whether the dysregulation of local factors may elicit the alteration of genetic expression in the endometrium. Similarly, it is uncertain whether the endometrial characteristics would remain consistent or could change along with a woman's reproductive life. Further longitudinal studies of the epigenetic controls or system biology are needed to elucidate the pathogenesis. Discovery of effective conservative treatments to improve the reproductive outcomes of patients with adenomyosis is still warranted.

Abstract
Adenomyosis is a benign gynecological disorder associated with abnormal uterine bleeding, dysmenorrhea, dyspareunia and infertility, requiring a life-long management plan through medical or surgical treatment. The choice depends on woman's age, reproductive status and clinical symptoms. However, until now no drug labelled for adenomyosis is available; thus, the present review will focus on medical treatments currently used for adenomyosis and those in development. Adenomyosis may be considered a sex steroid hormone-related disorder associated with an intense inflammatory process. The use of gonadotropin-releasing hormone agonists (GnRH-a) for treating adenomyosis is described blocking the hypothalamic-pituitary-gonadal axis; however, it has long been associated with frequent and intolerable hypoestrogenic side effects. An antiproliferative effect of progestins suggests their use for treating adenomyosis, reducing bleeding and pain. Continuous oral norethisterone acetate or medroxyprogesterone acetate may help to inducing regression of adenomyosis, relief pain and reduce bleeding. The use of vaginal danazol has therapeutic effect on adenomyosis combining progestogenic and anti-inflammatory activity. The intrauterine device releasing levonorgestrel (Lng-IUD) is widely assessed in menorrhagia, and has been shown to be extremely effective in resolving pain and bleeding symptoms associated with adenomyosis. Recent data show a therapeutic effect of dienogest on adenomyosis symptoms. New drugs are under development for the treatment of adenomyosis, such as aromatase inhibitors (AIs) and selective estrogen receptor modulators (SERMs), that produce a hypoestrogenic environment reducing pain, but are correlated with some adverse effects and a recurrence of symptoms after discontinuation of treatment. Selective progesterone receptor modulators (SPRMs) may reduce adenomyosis-associated pelvic pain, by inhibiting endometrial proliferation and suppressing adenomyotic lesion growth, as shown in animal models; however, the long-term effect with SPRMs needs further determination.

Prostaglandin levels, vaginal innervation, and cyst innervation as peripheral contributors to endometriosis-associated vaginal hyperalgesia in rodents. Mol Cell Endocrinol 2016; 437:120-129.

Abstract
Endometriosis is a painful condition characterized by growth of endometrial cysts outside the uterus. Here, we tested the hypothesis that peripheral innervation and prostaglandin levels contribute to endometriosis-associated pain. Female Sprague-Dawley rats (n = 16) were surgically instrumented by transplanting uterine tissue onto mesenteric arteries within the peritoneal cavity to create a model of endometriosis which forms extra-uterine endometrial cysts and vaginal hyperalgesia. Our results describe a significant positive correlation between endometriosis-induced vaginal hyperalgesia and cyst innervation density (sensory, r = 0.70, p = 0.003; sympathetic, r = 0.55, p = 0.03), vaginal canal sympathetic innervation density (r = 0.80, p = 0.003), and peritoneal fluid levels of the prostaglandins PGE2 (r = 0.65, p = 0.01) and PGF2α (r = 0.63, p = 0.02). These results support the involvement of cyst innervation and prostaglandins in endometriosis-associated pain. We also describe how sympathetic innervation density of the vaginal canal is an important predictor of vaginal hyperalgesia.

Abstract
OBJECTIVES To evaluate the in vivo effect of dienogest on proliferation, apoptosis, aromatase expression, vascular density, nerve growth factor (NGF) expression and nerve fiber density in human adenomyosis tissue. STUDY DESIGN Twelve women who underwent hysterectomy for adenomyosis were enrolled. Six patients received dienogest treatment prior to hysterectomy (dienogest group), and age-matched six patients who had not received any hormonal treatment for ≥3 months before surgery (control group). Cell proliferation, vascular and nerve fiber density in adenomyosis tissue were evaluated by staining for Ki67, von Willebrand factor and PGP9.5, respectively. Apoptosis was detected using the TUNEL assay. The expression aromatase and NGF were evaluated by staining for corresponding antibodies. RESULTS The proportion of Ki67 positive epithelial cells was significantly lower in samples from dienogest-treated patients in comparison with controls (p<0.05). The density of blood vessels in adenomyosis was marginally lower in the dienogest group in comparison with controls but statistical significance was not reached (p=0.07). The intensity of NGF expression and the density of nerve fibers were significantly lower in the dienogest group compared with controls (p<0.05 for both). CONCLUSION This study demonstrates that adenomyosis, taken from patients treated with dienogest, shows remarkable histological features, such as reductions in proliferation, NGF expression and nerve fiber density. These findings indicate the impact of dienogest on local histological events, and explains its therapeutic effect on adenomyosis.

Abstract
OBJECTIVES To assess the association of adenomyotic foci with co-existing benign ovarian cysts. METHODS This prospective cross-sectional study consisted of 100 consecutive hysterectomy specimens referred to Histopathology Section of Pathology Department, Peshawar Medical College, Peshawar, Pakistan by its attached teaching hospitals from January 2011 to December 2012. Hematoxylin and eosin stained sections were examined for adenomyotic foci and the presence of co-existent ovarian cysts. For evaluation of estrogen receptor (ER) status immunohistochemical stains were applied and H-scoring system was used with a score greater than 50 as positive. RESULTS Out of the 100 hysterectomy specimens, 25 cases had both adenomyosis and ovarian cysts. The ER status of adenomyotic foci was positive in 20% cases and negative in 80% cases. The commonest type of ovarian cyst was hemorrhagic luteal cyst (28%), followed by serous and mucinous cystadenoma (20%) each. Out of the 28% cases of functional cysts, 71.5% were ER positive and 28.5% were ER negative. The p-value for association of ER status of adenomyotic foci with functional cysts was 0.0004; however, p-value was not significant in comparing cases with controls. All 72% cases of nonfunctional cysts were ER negative. However, 44% of functional cysts were not associated with adenomyotic foci. CONCLUSION This study concludes that besides functional ovarian cysts, other local factors may be responsible for the development of adenomyosis.
