Abstract
Uterine leiomyomas (ULs) are the most common benign smooth muscle cell steroid-dependent tumors that occur in women of reproductive age. Progesterone (P4) is a major hormone that promotes the ULs development and growth. P4 action in ULs is mediated mainly by its nuclear progesterone receptors (PGRs), although rapid non-genomic responses have also been observed. Data on the membrane progesterone receptors (mPRs) regulated signaling pathways in ULs in the available literature is still very limited. One of the essential characteristics of ULs is the excessive production of extracellular matrix (ECM). P4 has been shown to stimulate ECM production and collagen synthesis in ULs. Recent research demonstrated that, despite their benign nature, ULs may present with abnormal vasculature. P4 has been shown to regulate angiogenesis in ULs through the upregulation of vascular endothelial growth factor (VEGF) and by controlling the secretion of permeability factors. This review summarizes the key findings regarding the role of PGRs and mPRs in ULs, especially highlighting the potential ECM and angiogenesis modulation by P4. An increased understanding of this mechanistic role of nuclear and specifically mPRs in the biology of P4-modulated ECM and angiogenesis in the growth of ULs could turn out to be fundamental for developing effective targeted therapies for ULs.

Abstract
BACKGROUND Uterine fibroids are the most common benign tumor in women. According to literature, submucosal myomas have a negative effect on reproductive outcomes in women undergoing assisted reproductive techniques (ART) but there are fewer data concerning intramural fibroids. During last years, ulipristal acetate (UPA) 5 mg was widely used as medical option of fibroid's treatment, but from 2020, the Pharmacovigilance Risk Assessment Committee (PRAC) has revoked the marketing authorization after some cases of liver toxicity. METHODS In this observational, retrospective study we collected data from a sample of 23 women affected by symptomatic uterine fibroids (from type 1 to type 7 according FIGO classification) followed in our center for assisted reproduction from 2016-2019. All patients received 5 mg/day UPA for three months, followed by two months of wash-out therapy. A group of 13 women treated with UPA, with intramural fibroid not distorting the uterine cavity, after wash-out therapy, affected by tubal or idiopathic factors of infertility too, underwent ART. We also evaluated a control group of women, not affected by fibroids, randomly selected from a general group of our ART patients, similar by age, BMI, and cause of infertility only idiopathic or tubal factors. We evaluated the impact of UPA on reduction of fibroid volume, symptomatology and distortion of the cavity in all the women treated, and the IVF (in-vitro fertilization) outcome between the fibroid group of women affected by intramural fibroids who underwent ART, and the control group. RESULTS In all the women treated with UPA the overall median fibroid volume pretreatment was 45.168±35.360 mm3, that decreased to a mean value of 22.592±22.116 mm3 post one cycle of UPA, with an overall mean decrease of -22.586 mm3 (of 49%) statistically significant (P=0.00001). After treatment, the distortion of the uterine cavity reduced in high percentage of cases: 85,71% (type 1-2), χ2 difference in respect to the value pretreatment of 0.3941, and 86.96% of patients subjectively referred an improvement in the symptomatology. In the group of 13 women that undergone ART, after one IVF cycle for each patient, we obtained 61% of positivity of dosage of beta human chorionic gonadotropin (hCG) after UPA treatment, and we obtained a similar value in the control group. CONCLUSIONS In our little sample we have observed that UPA represented a valid non-invasive medical treatment strategy for fibroids in women candidate for (IVF, not only in women affected by sub-mucosal, but also by intramural fibroids not distorting uterine cavity. After a single, three months course of treatment, we obtained good results in terms of reduction of fibroid's volume and improvement of symptomatology, without side effects, preparing a more favorable environment for ART.

Abstract
Uterine leiomyomas are the most common benign gynecologic tumors. This study was aimed to identify single nucleotide polymorphism of Fanconi anemia complementation group A (FANCA), associated with the rate of proliferation in uterine leiomyomas. In vitro study of patient-derived primary-cultured leiomyoma cells and direct sequencing of fresh frozen leiomyoma from each subject was conducted. Leiomyomas obtained from 44 patients who had underwent surgery were both primary-cultured and freshly frozen. Primary-cultured leiomyoma cells were divided into, according to the rate of proliferation, fast and slow groups. Single nucleotide polymorphism (SNP) of FANCA were determined from fresh frozen tissues of each patient using direct sequencing. Direct sequencing revealed a yet unidentified role of FANCA, a caretaker in the DNA damage-response pathway, as a possible biomarker molecule for the prediction of uterine leiomyoma proliferation. We identified that rs2239359 polymorphism, which causes a missense mutation in FANCA, is associated with the rate of proliferation in uterine leiomyomas. The frequency of C allele in the fast group was 35.29% while that in slow group was 11.11% (odds ratio (OR) 4.036 (1.176–13.855), p = 0.0266). We also found that the TC + CC genotype was more frequently observed in the fast group compared with that in the slow group (OR 6.44 (1.90–31.96), p = 0.0227). Taken together, the results in the current study suggested that a FANCA missense mutation may play an important regulatory role in the proliferation of uterine leiomyoma and thus may serve as a prognostic marker.

Abstract
Objective A retrospective study was performed to evaluate the safety and feasibility of cesarean myomectomy among pregnant women with uterine fibroids (UFs). Methods Upon data collection, the pregnant women with UF underwent cesarean section in the 39 hospital divided into two groups: cesarean myomectomy group, receiving cesarean section and myomectomy; cesarean group, receiving cesarean section only. Information about the type, location, and number of UFs was collected from the medical records or the prenatal ultrasound examinations. Results In the cesarean myomectomy group, the proportion of subserous UFs was significantly higher than the cesarean group (65.6% versus 49.3%, P < 0.0001). The comparison of postpartum hemorrhage, neonatal weight, fetal distress, and neonatal asphyxia showed no statistical significance. Multivariate logistic regression analysis demonstrated that birth weight ≥4000 g (OR 3.1, 95% CI:1.6–6.0) and presence of diameter > 5 cm fibroids (OR 2.2, 95%CI:1.3–4.0) were high risk factors for PPH ≥1,000 ml. Conclusions Myomectomy during cesarean section was a common procedure in mainland China. Myomectomy cesarean could be safe and feasible based on the estimation by experienced obstetricians. During the procedure, special attention should be paid to a large-sized leiomyoma ≥5cm and birth weight ≥4,000 g.

Abstract
OBJECTIVES Myomas are defined as benign tumours that arise from smooth muscle cells of the uterus. Clinically, they are found in 5-77% of women of reproductive age. The prevalence rate varies considerably in the literature and a large number of fibroids do not cause symptoms. The lifetime risk of acquiring myomas is 70% for Caucasian women and ≥ 80% for African American women. MATERIALS/METHODS The data of 265 patients undergoing surgery for symptomatic myomas by laparoscopy or laparotomy, performed in the gynaecological department of Hannover Medical School, Hannover, Germany, between 2009 and 2013, were retrospectively analysed in this retrospective design study. RESULTS High pregnancy rates (up to 70%) and birth rates (up to 86%) after myomectomy, regardless of the surgical approach adopted, were found in the current study. The trend was that ≥ 3 myomas and those that were ≥ 6 cm in size were almost always removed by laparotomy in our clinic. It was possible to remove up to 42 myomas without having to perform a hysterectomy. A statistically significant negative correlation was observed in relation to the association between the size of the largest myoma extracted and the pregnancy rate (p = 0.02). A statistically significant correlation between the number of removed myomas and the pregnancy rate was observed for patients who wished to bear children (p = 0.010). Elevated complication rates (of up to 50%) were reported for more than three extracted myomas with a statistically significance (p = 0.0471). CONCLUSIONS It is necessary to ensure sound preoperative selection of the surgical approach in order to achieve the most optimal results, especially for those patients who wished to bear children.

Abstract
Uterine fibroids are the most common type of benign gynecologic mass, and are present in up to 80 percent of women. Research exploring risk factors for fibroids presents conflicting or inconclusive findings. Symptoms for up to 50 percent of women experiencing fibroids include heavy menstrual bleeding, pelvic pressure or pain and gastrointestinal and genitourinary changes. Diagnosis is made by history and symptoms, physical examination and imaging. Several treatment options are available, and are based on symptoms, preferences and reproductive plans. Given the high prevalence of fibroids and the potential for women's health implications, it is essential that clinicians are aware of the latest evidence regarding fibroids to provide the highest quality of care for women whose health is affected by this condition.

Abstract
Renal cell carcinoma is the most common malignant renal tumor in the adults. Significant advances have been made in the management of localized and advanced renal cell carcinoma. Surgery is the standard of care and accurate pre-operative staging based on imaging is critical in guiding appropriate patient management. Besides staging, imaging plays a key role in the post-operative surveillance and evaluation of response to systemic therapies. Both CT and MR are useful in the staging and follow up of renal cell carcinoma, but CT is more commonly used due to its lower costs and wider availability. In this article, we discuss and illustrate the role of multi-detector CT in pre-operative staging, post-operative surveillance, and evaluation of response to systemic therapy in renal cell carcinoma.

Abstract
The aim of this study was to elucidate whether metformin can regulate the expression of vascular endothelial growth factor (VEGF) in rat-derived uterine leiomyoma cells (ELT-3 cells). In vitro studies were conducted using ELT-3 cells. Under normoxic conditions, metformin suppressed VEGF protein levels in the supernatant and cells in a dose-dependent manner. In hypoxia-mimicking conditions, VEGF and hypoxia-inducible factor-1α (HIF-1α) proteins were both highly expressed and were suppressed by the metformin treatment. Metformin did not affect HIF-1α mRNA levels, which indicated that its effects occurred at the post-translational level. Metformin inhibited mammalian target of rapamycin complex 1 (mTORC1) activity by phosphorylating the mTORC1 component raptor. This study revealed the anti-angiogenic activity of metformin in ELT-3 cells by suppressing the expression of VEGF via the mTORC1/HIF-1α pathway. These results indicate that metformin may represent an effective alternative in the future treatment of uterine leiomyomas.

Abstract
OBJECTIVE To investigate which clinical characteristics will influence the pregnancy rate and live birth rate after myomectomy. SUBJECTS AND METHODS Data of clinical characteristics and reproductive outcome from 471 patients who wished to conceive and who underwent abdominal or laparoscopic myomectomy in the Obstetrics and Gynecology Hospital of Fudan University from January 2008 to June 2012 were retrospectively analyzed. RESULTS Average age in the pregnancy group (30.0±3.7 years) and the nonpregnancy group (31.2±4.1 years) was statistically different (P=.000). The diameter of the biggest myoma had a positive relationship with the pregnancy rate when it was <10 cm (rs=0.095, P=.039). Abortions before myomectomy, operation type, number, location, and classification of myomas, uterine cavity penetration, and uterine volume seemed not to influence the pregnancy rate (P>.05). The location of the myoma may influence the live birth rate after myomectomy (rs=0.198, P=.002). Anterior and posterior myomas were associated with higher live birth rates than other locations (P=.001). The average interval between myomectomy and pregnancy was 16.0±8.7 months, and there was no difference between the abdominal (17.2±8.6 months) and laparoscopic (15.2±8.8 months) groups (P=.102). The interval in the live birth group was 15.0±8.4 months, and that in the non-live birth group was 18.9±9.3 months; the difference was significant (P=.005). CONCLUSIONS Patients' age, myoma size and location, and interval between myomectomy and pregnancy may influence the pregnancy rate and live birth rate after myomectomy.

Abstract
BACKGROUND To assess the impact of intramural fibroids on the intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycle outcome, when there is no compression of the endometrial cavity. METHODS In this retrospective, matched control study, the ICSI-ET outcome of sixty-two patients (Group I) with intramural fibroid (mean diameter <7 cm) and normal endometrial cavity demonstrated by office hysteroscopy was compared with matched-control group of patients (n = 301) with no fibroid (Group II). The diagnosis of fibroids was done by transvaginal ultrasonography. RESULTS The mean age in fibroid group was 32.66 +/- 5.30 while this figure was 32.95 +/- 3.98 in control group. The clinical pregnancy rate was significantly lower in the fibroid group although fibroids not distorting the uterine cavity (25.8% vs. 39.9%, p = 0.04). In fibroid group the implantation rate was significantly lower than control group (20.97 +/- 37.93 vs.32.89 +/- 43.18%, p = 0.04). However, spontaneous abortion rate was higher in fibroid group but it did not reach the significant level (12.5% vs. 9.2%, p > 0.05). CONCLUSION Women having intramural leiomyomas not encroaching on the uterine cavity have unfavorable ICSI/ET outcomes comparable to those of women without such leiomyomas. Therefore, myomectomy may be a good option for such patients with intramural fibroids even they do not have any endometrial distortion.

Abstract
Uterine leiomyomas have been reported to metastasize to various organs including the lungs, skeletal muscles, bone marrow, peritoneum, and heart. They may present with symptoms related to the metastases several years after hysterectomy. These tumors regress after menopause, and it is rare to detect active tumors in postmenopausal women. Despite their ability to metastasize, they are considered to be benign due to the lack of anaplasia. Pulmonary benign metastasizing leiomyoma is usually detected in the form of pulmonary nodules incidentally on imaging. Tissue biopsy of these nodules is required to identify them as benign metastasizing leiomyomas. Immunohistochemical analysis and molecular profiling may further help detect any malignant transformation in it. Untreated pulmonary benign metastasizing leiomyoma may result in the formation of cystic structures, destruction of lung parenchyma, and hemothorax and may cause respiratory failure. Surgical resection and hormonal therapy help prevent progression of this disease and provide an avenue for a cure.

Abstract
Gonadotropin-releasing hormone (GnRH) antagonists, which became commercially available from 1999, have been used for the prevention of premature luteinizing hormone (LH) surges in controlled ovarian stimulation for in vitro fertilization or intracytoplasmic sperm injection. This review focuses on the recent literature on the use of GnRH antagonists and provides guidelines for optimal use in light of increasing evidence showing that GnRH antagonists are safe and effective, allowing flexibility of treatment in a wide range of patient populations. This includes patients undergoing first-line controlled ovarian stimulation, poor responders, and women diagnosed with polycystic ovary syndrome. The GnRH antagonist offers a viable alternative to the long agonists, providing a shorter duration of treatment with fewer injections and with no adverse effects on assisted reproductive technology outcome. This results in a significantly lower amount of gonadotropins required, which is likely to lead to improved patient compliance.

Abstract
Biomarkers are biologic compounds that are easily accessible and reflect normal physiology or pathology. They are useful in a variety of clinical situations that involve detection of subclinical disease, risk stratification, preoperative planning, and monitoring treatment. A useful intervention needs to exist for a biomarker to be an effective tool. Many compounds have been investigated as potential biomarkers for the diagnosis and surveillance of uterine leiomyomas. Most of these compounds demonstrate subtle differences among patients when leiomyomas are compared with controls. The compounds investigated lack the diagnostic accuracy necessary to add any benefit to the current available modalities used to diagnose and monitor uterine leiomyomas.

Abstract
Uterine disorders like usual infertility factors (male factor, ovarian and tubal problems of women) may affect the outcome of infertility treatment in infertile patients. In our clinical trial, 110 couples diagnosed with infertility were candidate for intra uterine insemination (IUI). The patients were divided randomly into two equal groups (n = 55): In group one (control group), patients without hysteroscopy underwent ovulation induction by clomiphene citrate and hCG followed by intrauterine insemination. The second group (experiment group), patients were undergoing hysteroscopy before intra uterine insemination on the day 21 of the cycle and due to abnormal findings, going under surgical treatment if they needed. The rates of pregnancy complications in patients were evaluated. The age, BMI, kind of infertility, duration of infertility, number of previous trial, duration of stimulation, the type of procedures used and semen analysis (TMC, Motility and morphology of sperm) were similar for both groups and no statistically significant differences emerged at all between them. In experimental group, hysteroscopy revealed pathology in the uterine cavity in 26 out of 55 cases. The overall rates of clinical pregnancy were higher in experimental group compared to the control group. The findings from this study showed that the use of hysteroscopy as a diagnostic or therapeutic procedure before IUI, can increase the rate of pregnancy and finally decrease the failure rate of infertility treatment and perinatal complications in infertile couples.

Abstract
PURPOSE Uterine leiomyomas are common, benign, reproductive tract tumors affecting a majority of reproductive aged women. They are associated with gynecologic morbidity and detrimentally affect reproductive potential. The etiology of leiomyomas is poorly understood and their diagnosis prior to treatment with Assisted Reproductive Technologies (ART) represents a management dilemma. The purpose of this paper is to review known genetic and molecular contributions to the etiologies of leiomyomas, describe their impact on ART outcomes and reproductive potential, and review alternative therapies and future directions in management. METHODS A critical review of the literature pertaining to genetic component of uterine leiomyomas, their impact on ART and pregnancy and leiomyoma therapeutics was performed. RESULTS Uterine leiomyomas are characterized by complex molecular mechanisms. Their location and size determines their potential detriment to ART and reproductive function and novel therapeutic modalities are being developed. CONCLUSION The high prevalence of uterine leiomyomas and their potential detrimental influence on ART and reproductive function warrants continued well-designed studies to ascertain their etiology, optimal treatment and novel less morbid therapies.

Abstract
BACKGROUND The efficacy and safety of oral ulipristal acetate for the treatment of symptomatic uterine fibroids before surgery are uncertain. METHODS We randomly assigned women with symptomatic fibroids, excessive uterine bleeding (a score of >100 on the pictorial blood-loss assessment chart [PBAC, an objective assessment of blood loss, in which monthly scores range from 0 to >500, with higher numbers indicating more bleeding]) and anemia (hemoglobin level of ≤10.2 g per deciliter) to receive treatment for up to 13 weeks with oral ulipristal acetate at a dose of 5 mg per day (96 women) or 10 mg per day (98 women) or to receive placebo (48 women). All patients received iron supplementation. The coprimary efficacy end points were control of uterine bleeding (PBAC score of <75) and reduction of fibroid volume at week 13, after which patients could undergo surgery. RESULTS At 13 weeks, uterine bleeding was controlled in 91% of the women receiving 5 mg of ulipristal acetate, 92% of those receiving 10 mg of ulipristal acetate, and 19% of those receiving placebo (P<0.001 for the comparison of each dose of ulipristal acetate with placebo). The rates of amenorrhea were 73%, 82%, and 6%, respectively, with amenorrhea occurring within 10 days in the majority of patients receiving ulipristal acetate. The median changes in total fibroid volume were -21%, -12%, and +3% (P=0.002 for the comparison of 5 mg of ulipristal acetate with placebo, and P=0.006 for the comparison of 10 mg of ulipristal acetate with placebo). Ulipristal acetate induced benign histologic endometrial changes that had resolved by 6 months after the end of therapy. Serious adverse events occurred in one patient during treatment with 10 mg of ulipristal acetate (uterine hemorrhage) and in one patient during receipt of placebo (fibroid protruding through the cervix). Headache and breast tenderness were the most common adverse events associated with ulipristal acetate but did not occur significantly more frequently than with placebo. CONCLUSIONS Treatment with ulipristal acetate for 13 weeks effectively controlled excessive bleeding due to uterine fibroids and reduced the size of the fibroids.

Abstract
OBJECTIVE To describe a rare finding of a large leiomyoma and recurrence in an adolescent. DESIGN Case report. SETTING Major academic medical center. PATIENT(S) A 14-year-old gravida 0 presented with a 16-cm pelvic mass that was found to be an anterior uterine leiomyoma. INTERVENTION(S) Exploratory laparotomy with resection of leiomyoma followed by robotic myomectomy when the mass recurred. MAIN OUTCOME MEASURE(S) The incidence, pathogenesis, fertility implications, and treatment options for leiomyomas in adolescents. RESULT(S) Leiomyomas are rare in adolescents. The mass was resected and recurred within 1 year. There are no prior cases of recurrence in an adolescent. CONCLUSION(S) Benign leiomyomas should be considered in adolescents presenting with uterine masses, as malignancies are even less common. Myomectomy is the procedure of choice to preserve fertility in this population.

Abstract
Hysteroscopy is a widely used endoscopic method, the "gold standard" for the examination of uterine cavity changes. Office hysteroscopy is an intervention that makes the accomplishment of ambulant examination, opposite to the traditional method. Due to the small diameter of the device the anesthesia is unnecessary, because there is no need of the dilatation of the cervix. Indications of the examination are wide-ranging. Besides the abnormal uterine bleeding, it can be used in the examination of infertility, and those intrauterine changes (polyp, submucosus myoma, adhesion), that were diagnosed by other imagining methods that cause infertility complaints. The aim of our present review is recommend the use of this method because it does not need any preparation and it is minimal invasive. The use of traditional method that needs longer preparation, observation, anesthesia and operating theatre, is only suggested in cases of proven pathology.

Abstract
Uterine fibroids are benign tumours, which are associated with subfertility and early pregnancy loss. This study was carried out to examine the effect of submucous fibroids on concentrations of glycodelin, insulin-like growth factor binding protein-1 (IGFBP-1), interleukin-6 (IL-6), interleukin-10 (IL-10), tumour necrosis factor α (TNFα) and osteopontin in uterine flushings. Premenopausal women with a certain diagnosis of submucous fibroid confirmed on three-dimensional saline infusion sonohysterography were recruited into the study. The control group included women without ultrasonic evidence of any uterine or endometrial pathology. All women had uterine flushings performed 7days post LH surge. Enzyme linked immunoassays were performed to analyse glycodelin, IL-6, IL-10, TNFα and osteopontin, whilst immunoradiometric assay was used to analyse IGFBP-1. In 23 women with submucous fibroids, the concentrations of glycodelin and IL-10 in uterine flushings were significantly lower compared with 17 women in the control group (P=0.002; P=0.007, respectively). There were no significant differences between the two groups in concentrations of IGFBP-1, IL-6, TNFα and osteopontin. Women with submucous fibroids had significantly lower concentrations of glycodelin and IL-10 in mid-luteal phase uterine flushings. This finding may explain the association with submucous fibroids and adverse reproductive outcomes. Uterine fibroids are small growths from the muscle of the uterus (womb). Submucous fibroids protrude into the cavity of the womb. We do not know what causes fibroids to form and grow. In most women, fibroids cause no symptoms and they are sometimes detected on routine gynaecological examination. In some women, however, fibroids can cause heavier and longer menstrual periods. Another problem associated with fibroids is bleeding between periods. The effect of fibroids on fertility is not clear, but some doctors believe that they may also cause infertility and early miscarriage. This study tried to see whether presence of submucous fibroids has any effect on various substances produced by the lining of the womb to facilitate development of early pregnancy. Women with a confirmed diagnosis of submucous fibroids were asked to attend the clinic and have the uterine cavity flushed with a special solution 7days after ovulation. The fluid, which was taken back from the womb, was then analysed to measure the amounts of substances that favour pregnancy development. Women with a normal uterine cavity were also asked to have the uterine cavity flushed to act as a comparison. The study showed that the uterine cavities of women with submucous fibroids were producing decreasing amount of substances favourable to early pregnancy development. We speculate that this may explain why some women with submucous fibroids have difficulties falling pregnant. Our findings should be helpful to doctors advising women with submucous fibroids who wish to start a family.

Abstract
The present study was planned to review the pathophysiology of uterine myomas and emphasize the principles of logical management on the basis of literature review and synthesis of the author's experience. The growth of uterine myomas, the most common solid pelvic tumors in women, is related to genetic predisposition, hormonal influences and growth factors. The treatment options include pharmacologic, surgical and radiographic interventions. Most asymptomatic myomas can be followed serially for progressive growth or development of symptoms. The various diagnostic and therapeutic advancements available today permit higher management flexibility with safe options, which must be tailored to the individual patients requirement.

Abstract
Uterine leiomyomas are present in 30-70% of women of reproductive age. In addition to causing menstrual disorders and pain, uterine fibroids negatively affect fertility and pregnancy outcome for patients pursuing assisted reproduction. The two questions that have to be addressed are: which fibroids should be treated and how should they be treated? Submucosal fibroids are associated with a 70% reduction in delivery rate. Intramural fibroids had a lesser effect and reduced the delivery rate by approximately 30%. By contrast, studies have demonstrated that subserosal fibroids did not negatively impact fertility. Furthermore, both submucosal and intramural fibroids were associated with an increased risk of spontaneous miscarriage. Myomectomy is considered the treatment of choice to alleviate these detrimental effects. Further research is needed before alternative treatments can be recommended.

Abstract
PURPOSE To determine whether there is a superior treatment modality for 'poor' responders. METHOD Retrospective analysis of three stimulation regimens, with patients stratified based on age, stimulation regime and response in previous cycles ("poor' responder or "non poor" responder). Fertilisation, embryo utilisation and clinical pregnancy rates were assessed. There were a total of 1,608 cycles in the 'poor' responder and 8,489 cycles in the 'non poor' responder groups. RESULTS In 'poor' responders there was no significant difference in fertilisation rate, nor utilisation rate between the three stimulation regimes and no differences in the pregnancy rate/initiated cycle irrespective of age and stimulation regimen in any of the groups. 'Non poor' responders had a significantly greater pregnancy rate/initiated cycle for all stimulation regimens in both age groups compared with 'poor' responders. CONCLUSION This large retrospective study of 'poor' responders has not shown a difference in pregnancy rates/initiated cycle between stimulation regimens.

Abstract
There is debate regarding whether fibroids cause infertility or if they are simply an association. However, it is possible that fibroids are responsible for 2-3% of cases of infertility. The mechanisms by which these benign tumours could cause impaired reproductive function, both in terms of difficulty conceiving and early pregnancy loss, remain unclear. Myomectomy facilitates removal of a fibroid with preservation of reproductive potential. The procedure is associated with significant risks but, overall, some studies have suggested that this surgical option increases pregnancy rates significantly in women with fibroid-associated infertility. Miscarriage rates in women with fibroids and those who have undergone myomectomy vary considerably. It appears that miscarriage rates fall after myomectomy, although the overall rates of pregnancy loss remain higher than those seen in the general population. Fibroids affect 0.1-3.9% of pregnancies, and a number of complications encountered antenatally and post partum are thought to be directly related to the presence of these benign tumours. A number of contraceptive options exist for women with fibroids, with the choice depending on patient preference and both fibroid and patient characteristics.

Abstract
Uterine fibroids are composed of altered collagen fibrils and represent an arrested response to injury-initiating fibrosis. In many tissues, TSP-1 is secreted by adult macrophages and monocytes upon wounding and is involved in the activation of transforming growth factor beta. In the absence of TSP-1, the orchestrated process of wound healing is impaired. The authors obtained tissue from the edge and center of fibroids at the time of hysterectomy and compared them with adjacent myometrium. The pattern of TSP-1 and TSP-2 expression was correlated to that of COL1A1 and COL3A1. Collagen and hydroxyproline were increased in fibroids. Thrombospondin-1 was consistently underexpressed in both the edge and center of the fibroids, while COL1A1 and COL3A1 were consistently overexpressed. However, TSP-2 was inconsistently expressed. These findings lead to the conclusion that the underexpression of TSP-1 may contribute to the overall development of uterine fibroids.

Abstract
It is well known that focused ultrasound has a biologic effect on tissue. High intensity focused ultrasound (HIFU) on a small target area raises the temperature of the tissue enough to denaturate proteins and cause irreversible cell damage. The tight focus of the ultrasound energy allows delivery of the intended dose to a very precise location. The resulting coagulation necrosis is relatively painless. The application of this method in the human clinical setting has required pilot studies on an animal model. Although the treatment had a high success rate, there was a significant percentage of complications, mainly attributed to the technical drawbacks of the procedure. Therefore, this method has been modified for use in humans, and the HIFU is now guided, monitored and controlled by magnetic resonance imaging (MRI). In October 2004, Food and Drug Adiministration (FDA) approved MRI guided focused ultrasound treatment of uterine fibroids in humans. Since then, successful treatment of uterine myomas by HIFU has been performed in thousands of women.

Abstract
OBJECTIVE To investigate the relative expression and the DNA-binding status of estrogen receptors alpha and beta in fibroids and normal myometrial tissue to explore the molecular basis of altered estrogen responsiveness of leiomyomas. DESIGN Biopsy samples from uterine fibroids and adjacent normal myometrial tissue at the follicular phase of the menstrual cycle. SETTING Aretaieio University Hospital and the National Hellenic Research Foundation, Athens, Greece. PATIENT(S) Thirty-five patients who underwent hysterectomy or myomectomy because of myoma symptoms. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Deoxyribonucleic acid-binding status of estrogen receptors alpha and beta. RESULT(S) The level of messenger RNA expression of estrogen receptor alpha and beta and the level of estrogen receptor as a whole are increased on average to a similar extent in leiomyomas compared with normal myometrium. Occasionally, however, estrogen receptor alpha is disproportionately increased in leiomyomas, and this appears to increase the amount of estrogen receptor alpha that binds to the estrogen-responsive element of estrogen target genes as homodimer rather than as heterodimer with estrogen receptor beta. CONCLUSION(S) The estrogen receptor alpha-to-estrogen receptor beta expression ratio rather than the individual expression levels determines the fraction of DNA-binding homodimers of estrogen receptor alpha and possibly the growth potential of myomas.

Studies have analysed the reproductive results after myomectomy according to the size, location and number of fibroids removed, but data are insufficient about comparison of opening the uterine cavity or not during surgery. MATERIALS AND METHODS Two hundred twenty-nine abdominal myomectomies with the indication of infertility and/or recurrent pregnancy loss were analysed retrospectively. The main purpose was to compare postoperative pregnancy, delivery and miscarriage rates according to either the uterine cavity was opened or not during the surgery. As a secondary outcome postoperative pregnancy rates were assessed by location, size and number of fibroids. RESULTS There was no significant difference in reproductive results according to either the uterine cavity was opened or remained closed. Preoperative location, size and number of fibroids did not influence significantly the postoperative pregnancy rates. CONCLUSION Opening the uterine cavity does not impair postoperative pregnancy rates. Preoperative location, size and number of fibroids do not influence postoperative reproductive results.
