Abstract
Infertility is an important socio-economic problem due to the fact that planned childbearing occurs much later than three decades ago. In recent years, more attention has been paid to the role of uterine leiomyoma in the development of infertility. Uterine leiomyoma is a benign monoclonal, well-demarcated encapsulated tumor originating from the smooth muscle cells of the cervix or body of the uterus. Uterine leiomyoma is the most common uterine tumor in the reproductive age group, affecting 20-50 % of women. With conceptual changes in marriage and childbearing, the number of women over 35 with leiomyoma who want to have children has also increased significantly. The need to treat submucosal fibroids is widely recognized, but fibroids of other locations and sizes remain a clinical mystery. The purpose of the literature review was to determine the role of uterine fibroids in predicting infertility. It has been established that the incidence of uterine leiomyoma in women of reproductive age is on average about 40 %, infertility associated with this pathology occurs in 5-10 % of women. In 10 % of cases of infertility, uterine leiomyoma is the only established cause of infertility. Uterine leiomyoma is common among women of reproductive age, and as women continue to delay childbearing, an increasing number of patients will require fertility-preserving treatment options. Leiomyoma affects not only fertility but also obstetric outcomes. Women with intramural fibroids without cavity deformity have a 21 % reduction in live birth rates after in vitro fertilization compared with controls without fibroids. Despite advances in fundamental understanding of the biology of leiomyomas, the role of different fibroid variants remains a matter of discussion. The question of the negative impact of submucosal nodes on infertility today is not in doubt, and the effect of subserous and intramural nodes requires further study.

Abstract
Infertility is a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse. Uterine fibroids are the most common tumor in women, and their prevalence is high in patients with infertility. Fibroids may be the sole cause of infertility in 2–3% of women. Depending on their location in the uterus, fibroids have been implicated in recurrent pregnancy loss as well as infertility. Pregnancy and live birth rates appear to be low in women with submucosal fibroids; their resection has been shown to improve pregnancy rates. In contrast, subserosal fibroids do not affect fertility outcomes and their removal does not confer any benefit. Intramural fibroids appear to reduce fertility, but recommendations concerning their treatment remain unclear. Myomectomy should be discussed individually with the patient; other potential symptoms such as dysmenorrhea or bleeding disorders should be included in the indication for surgery.

Abstract
The reproductive system in males and females reflects a highly dynamic underlying physiology. Yet our current understanding of this system is still largely based upon relatively simplistic snapshots of individual component cells and tissues. Gamete production as well as gonadal hormone synthesis and its influence are the manifestations of dynamic and redundant informational networks and processes, whose qualitative and quantitative dimensions, especially through development from embryo through puberty and adulthood into ageing, are still largely uncharted. Whilst the recent huge advances in molecular science have helped to describe the components of the reproductive system in ever greater detail, how these interact and function in space and time dimensions is still largely obscure. Recent developments in microfluidics, stem cell biology, and the integration of single-cell transcriptomics with tissue dynamics are offering possible methodological solutions to this issue. Such knowledge is essential if we are to understand not only the normal healthy functioning of this system, but also how and why it is affected in disease or by external impacts such as those from environmental endocrine disruptors, or in ageing. Moreover, operating within a complex network of other physiological systems, its integrational capacity is much more than the generation of male and female gametes and their roles in fertility and infertility; rather, it represents the underpinning support for health and well-being across the lifespan, through pregnancy, puberty, and adulthood, into old age.

Abstract
Available evidence from IVF studies supports a detrimental effect of submucosal and intramural fibroids on embryo implantation. It is misleading, however, to infer evidence obtained in IVF settings to natural fertility. Therefore, a systematic review and meta-analysis was conducted on the effect of fibroids on natural fertility. Studies comparing fertile and infertile women, and those investigating whether the presence of fibroids was a risk factor, were reviewed, as well as studies comparing women with and without fibroids. The aim was also to establish whether the frequency of infertility differed between the two groups. Seven out of 11 selected studies did not aim to establish whether fibroids caused infertility but, rather, whether a history of infertility could be a risk factor for fibroids. A meta-analysis of the four remaining studies that concomitantly evaluated the presence of fibroids and infertility studies highlighted a common odds ratio of fibroids in subfertile women of 3.54 (95% CI 1.55 to 8.11). When focusing on the two most informative studies, i.e. the studies comparing time to pregnancy in women with and without fibroids, the common OR was 1.93 (95% CI 0.89 to 4.18). In conclusion, the association between fibroids and infertility has been insufficiently investigated. Epidemiological studies suggest, but do not demonstrate, that fibroids may interfere with natural fertility. Given the high prevalence of these lesions in women seeking pregnancy, further evidence is urgently needed.

Impact of intramural non-cavity-distorting leiomyoma on placental histopathology and perinatal outcome in singleton live births resulting from in vitro fertilization treatment. J Assist Reprod Genet 2020; 37:1963-1974.

Abstract
PURPOSE To evaluate the effect of non-cavity-distorting intramural leiomyomas on the placental histopathology pattern and perinatal outcome in singleton live births resulting from in vitro fertilization treatment. METHODS The study population included all singleton live births following in vitro fertilization treatment with autologous oocytes during the period from 2009 to 2017. Primary outcomes included anatomical, inflammation, vascular malperfusion, and villous maturation placental features. Secondary outcomes included fetal, maternal, delivery, and perinatal complications. RESULTS A total of 1119 live births were included in the final analysis and were allocated to the group of pregnancies with non-cavity-distorting intramural myomas (n = 101) and without myomas (n = 1018). After the adjustment for confounding factors, the non-cavity-distorting intramural myomas were found to be significantly associated with assisted placental delivery (OR 2.4; 95% CI 1.5-3.9), furcate cord insertion (OR 3.6; 95% CI 1.4-9.3), circumvallate membranes insertion (OR 5.2; 95% CI 1.4-19.3), chronic deciduitis (OR 8.2; 95% CI 1.6-42.2), focal intramural fibrin deposition (OR 25.1; 95% CI 2.1-306.2), subchorionic thrombi (OR 3.6; 95% CI 1.7-7.6), maternal vasculopathy (OR 2.5; 95% CI 1.2-5.5), and chorangioma (OR 5.9; 95% CI 1.4-25.2) as well as with the failure of labor progress (OR 2.4; 95% CI 1.3-4.4) and induction (OR 3.2; 95% CI 1.2-9.0). CONCLUSION Intramural non-cavity-distorting myomas have a significant impact on the placental histopathology with a higher incidence of dysfunctional labor.

Abstract
BACKGROUND Recent advances in proteomics present enormous opportunities to discover proteome related disparities and thus understanding the molecular mechanisms related to a disease. Uterine leiomyoma is a benign monoclonal tumor, located in the pelvic region, and affecting 40% of reproductive aged female. OBJECTIVE Identification and characterization of the differentially expressed proteins associated with leiomyogenesis by comparing uterine leiomyoma and normal myometrium. METHODS Paired samples of uterine leiomyoma and adjacent myometrium retrieved from twenty-five females suffering from uterine leiomyoma (n=50) were submitted to two-dimensional electrophoresis (2-DE), matrixassisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and to reverse transcription polymerase chain reaction (RT-PCR). RESULTS Comparison of protein patterns revealed seven proteins with concordantly increased spot intensities in leiomyoma samples. E3 ubiquitin-protein ligase MIB2 (MIB2), Mediator of RNA polymerase II transcription subunit 10 (MED10), HIRA-interacting protein (HIRP3) and Fatty acid binding protein brain (FABP7) were found to be upregulated. While, Biogenesis of lysosome-related organelles complex 1 subunit 2 (BL1S2), Shadow of prion protein (SPRN) and RNA binding motif protein X linked like 2 (RMXL2) were found to be exclusively present in leiomyoma sample. The expression modulations of the corresponding genes were further validated which corroborated with the 2-DE result showing significant upregulation in leiomyoma. We have generated a master network showing the interactions of the experimentally identified proteins with their close neighbors and further scrutinized the network to prioritize the routes leading to cell proliferation and tumorigenesis. CONCLUSION This study highlights the importance of identified proteins as potential targets for therapeutic purpose. This work provides an insight into the mechanism underlying the overexpression of the proteins but warrants further investigations.

Intra- and Inter-Rater Agreement Describing Myometrial Lesions Using Morphologic Uterus Sonographic Assessment: A Pilot Study. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2019; 38:2673-2683.

Abstract
OBJECTIVES To evaluate the intra- and inter-rater agreement for myometrial lesions using Morphologic Uterus Sonographic Assessment terminology. METHODS Thirteen raters with high (n = 6) or medium experience (n = 7) assessed 30 3-dimensional ultrasound clips with (n = 20) and without (n = 10) benign myometrial lesions. Myometrial lesions were reported as poorly or well defined and then systematically evaluated for the presence of individual features. The clips were blindly assessed twice (at a 2-month interval). Intra- and inter-rater agreements were calculated with κ statistics. RESULTS The reporting of poorly defined lesions reached moderate intra-rater agreement (κ = 0.49 [high experience] and 0.47 [medium experience]) and poor inter-rater agreement (κ = 0.39 [high experience] and 0.25 [medium experience]). The reporting of well-defined lesions reached good to very good intra-rater agreement (κ = 0.73 [high experience] and 0.82 [medium experience]) and good inter-rater agreement (κ = 0.75 [high experience] and 0.63 [medium experience]). Most individual features associated with ill-defined lesions reached moderate intra- and inter-rater agreement among highly experienced raters (κ = 0.41-0.60). The least reproducible features were myometrial cysts, hyperechoic islands, subendometrial lines and buds, and translesional flow (κ = 0.11-0.34). Most individual features associated with well-defined lesions reached moderate to good intra- and inter-rater agreement among all observers (κ = 0.41-0.80). The least reproducible features were a serosal contour, asymmetry, a hyperechoic rim, and fan-shaped shadows (κ = 0.00-0.35). CONCLUSIONS The reporting of well-defined lesions showed excellent agreement, whereas the agreement for poorly defined lesions was low, even among highly experienced raters. The agreement on identifying individual features varied, especially for features associated with ill-defined lesions. Guidelines on minimum requirements for features associated with ill-defined lesions to be interpreted as poorly defined lesions may improve agreement.

Abstract
The objective of the study was to examine the expression and cellular distribution of key signaling components of the phosphatidylinositol-3-kinase (PI3K)/Phosphatase and Tensin Homolog Deleted on Chromosome Ten (PTEN)/Protein Kinase B (PKB/Akt) pathway during the window of implantation in infertile women with noncavity-distorting intramural uterine fibroids (n = 21) as compared to fertile controls (n = 15). Relative gene expression analysis of PIK3CA, PTEN, Akt1, and Akt2 genes in midluteal endometrial biopsies was performed by real-time polymerase chain reaction. Immunohistochemistry was used to evaluate the expression of PIK3CA, PTEN, phospho-PTEN, Akt1, Akt2, phospho-Akt1 (serine 473), phospho-Akt1 (threonine 308), and Ki67 proteins. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling assay was performed for apoptosis detection. In comparison to fertile controls, significant upregulation of Akt1 messenger RNA levels (2.16-fold; P < .05); cell-specific upregulation of the proteins phospho-PTEN ( P < .05), Akt1 ( P < .05), Akt2 ( P < .05), and p-Akt (S473; P < .001); and downregulation of PTEN ( P < .01) were observed in endometrium of infertile women with intramural fibroids. The ratio of p-PTEN/PTEN and p-Akt1 (S473)/Akt1 was also significantly higher in infertile women. Increased Ki67 labeling index in the glandular epithelium and significantly lower apoptotic index in glandular epithelium and stroma were seen in infertile women during the window of implantation. Aberrant Akt activation and the associated imbalance in endometrial proliferation and apoptosis observed in infertile women with intramural fibroids during the midsecretory phase might contribute to impaired endometrial receptivity leading to infertility in these patients.

Abstract
The appropriate biomechanical function of the uterus is required for the execution of human reproduction. These functions range from aiding the transport of the embryo to the implantation site, to remodeling its tissue walls to host the placenta, to protecting the fetus during gestation, to contracting forcefully for a safe parturition and postpartum, to remodeling back to its nonpregnant condition to renew the cycle of menstruation. To serve these remarkably diverse functions, the uterus is optimally geared with evolving and contractile muscle and tissue layers that are cued by chemical, hormonal, electrical, and mechanical signals. The relationship between these highly active biological signaling mechanisms and uterine biomechanical function is not completely understood for normal reproductive processes and pathological conditions such as adenomyosis, endometriosis, infertility and preterm labor. Animal studies have illuminated the rich structural function of the uterus, particularly in pregnancy. In humans, medical imaging techniques in ultrasound and magnetic resonance have been combined with computational engineering techniques to characterize the uterus in vivo, and advanced experimental techniques have explored uterine function using ex vivo tissue samples. The collective evidence presented in this review gives an overall perspective on uterine biomechanics related to both its nonpregnant and pregnant function, highlighting open research topics in the field. Additionally, uterine disease and infertility are discussed in the context of tissue injury and repair processes and the role of computational modeling in uncovering etiologies of disease.

Abstract
This study was designed to examine the expression and cellular distribution of homeobox ( HOX) genes ( HOXA10 and HOXA11) and cell adhesion molecules (E-cadherin, N-cadherin, and β-catenin) during the window of implantation in infertile women with noncavity-distorting intramural (IM) fibroids (n = 18) and in fertile controls (n = 12). Quantitative real-time polymerase chain reaction and immunohistochemistry were used to evaluate the messenger RNA (mRNA) levels and protein expression, respectively. When compared to fertile controls, reduced HOXA10 and HOXA11 transcript and protein levels were observed in infertile women. However, changes only in the expression of HOXA10 mRNA (-1.72-fold; P = .03) and stromal protein ( P = .001) were statistically significant. Significantly lower E-cadherin mRNA (-10.97-fold; P = .02) and protein levels were seen in infertile patients. E-cadherin immunostaining was significantly reduced both in the luminal ( P = .048) and in the glandular ( P = .014) epithelium of endometrium from infertile patients when compared to controls. No significant change was observed either in the mRNA levels or in the immunoexpression of N-cadherin and β-catenin. However, a trend toward lower N-cadherin expression in the luminal epithelium ( P = .054) and decreased β-catenin expression in the glandular epithelium ( P = .070) was observed in infertile patients. The present findings suggest that altered endometrial HOXA10 and E-cadherin mRNA and protein expression observed in infertile women with IM fibroids during the mid-secretory phase might impair endometrial receptivity leading to infertility in these patients.
