Abstract
Endometriosis-related infertility is one of the most debated topics in reproductive medicine. In recent years, prolonged pre-cycle hormonal regimens gained attention as a mean of improving the assisted reproduction technologies (ART) success rates in endometriosis patients. GnRH agonists, dienogest, medroxyprogesterone acetate, and aromatase inhibitors are the most studied medications. Conflicting results and a high risk of bias exist in almost all of the conducted studies in the field. However, current evidence suggests that pre-cycle treatment with GnRH agonists may be beneficial for patients with stage III/IV endometriosis. Dienogest and medroxyprogesterone acetate-based progestin-primed ovarian stimulation protocol was shown to be comparable to the prolonged GnRH agonists protocol. Finally, aromatase inhibitors seem to be of limited benefit to the assisted reproductive outcomes of endometriosis patients. Although it is challenging to draw any clinical conclusions, pre-cycle hormonal treatments seem to be best indicated in endometriosis patients who had previously failed ART treatment.

Abstract
Objective: The aim of this study is to assess the postoperative efficacy of the combined administration of dienogest (DNG) and gonadotropin-releasing hormone agonists (GnRH-a) in patients diagnosed with endometriosis (EMS), while acknowledging the extensive use of DNG in the extended therapeutic management of EMS. Methods: In this retrospective study, a cohort of 154 patients who underwent conservative surgical intervention for EMS were scrutinized. The cohort was stratified into two distinct groups based on their prescribed pharmacological regimens. Group A, 70 patients received postoperative oral administration of DNG at a dosage of 2 mg/day, whereas Group B, 84 patients underwent treatment involving 3 to 4 injections of GnRH-a post-surgery, followed by DNG therapy. Parameters assessed included pelvic pain visual analog scale (VAS) scores, quality of life metrics (EHP-5), and the incidence of adverse reactions within both groups. Results: Both groups exhibited sustained low VAS scores following the prescribed treatments. The predominant occurrence of adverse bleeding patterns manifested predominantly within the initial 6 months of the treatment. Notably, Group B demonstrated a significantly diminished of experiencing frequent and irregular bleeding in comparison to the DNG group (20.0% vs. 8.3%, 12.9% vs. 3.6%, p < 0.05). The administration of GnRH-a did not exacerbate the impact on bone health. Subsequent to health promotion interventions, the incidence of weight gain in both groups declined to 7.1% during the 6-month follow-up (p < 0.05). Group B exhibited a 100% satisfaction rate with the treatment, concomitant with a noteworthy reduction in EHP-5 scores (p < 0.05). Patients with deep infiltrating endometriosis (DIE) nodules displayed marginally higher postoperative VAS scores than their non-DIE counterparts (0.89 ± 0.96 vs. 0.49 ± 0.78). However, with sustained medication use, pain scores within the DIE group exhibited a continual decrease, maintaining a low level of 0.29 ± 0.67 at 12 months and beyond. Conclusion: The short-term adjunctive use of GnRH-a prior to DNG treatment postoperatively in patients with EMS proves efficacious in mitigating early adverse bleeding, enhancing patient adherence, and improving overall quality of life. Notably, this therapeutic approach demonstrates favorable safety profiles and is equally effective in patients with DIE.

Abstract
The different etiopathogenetic mechanisms and the diversity of clinical features of endometriosis has not yet allowed to identify a causal pharmacological monotherapy satisfying the unresolved medical needs in this important female disease. Therefore, despite the search for new therapeutic principles for the indication, the strategy of gradual optimization of established therapeutic principles should not be disregarded.In the case of progestins, the fact that each compound has its own, specific profile may allow to study the therapeutic relevance of the various signal cascades influenced by their receptors.Using the example of the progestin dienogest, the different genomic and non-genomic mechanisms of action are discussed. It is pharmacodynamic profile is unique compared to other progestins.In light of the emerging multitude of pathomechanisms in endometriosis, a monotherapy may not be possible, and then the search for broad spectrum compounds or combination therapies with dual or multiple mode of action in a clinically relevant dose range might be considered. The progestogenic action may greatly benefit from, by way of example, additional anti-inflammatory and/or anti-fibrotic and/or pro-apoptotic activities. Such a strategy could lead to new drug classes.

Abstract
Introduction: Ureteral endometriosis is a rare disease affecting women of childbearing age which presents with nonspecific symptoms and it may result in severe morbidity. The aim of this study was to review evidence about incidence, pathogenesis, clinical presentation, diagnosis, and management of ureteral endometriosis. Materials and Methods: PubMed Central database was searched to identify studies reporting cases of ureteral endometriosis. “Ureter” or “Ureteral” and “Endometriosis” were used as key words. Database was searched for articles published since 1996, in English without restrictions regarding the study design. Results: From 420 studies obtained through database search, 104 articles were finally included in this review, including a total of 1384 patients with ureteral endometriosis. Data regarding age, location, pathological findings, and interventions were extracted. Mean patients' age was 38.6 years, whereas the therapeutic arsenal included hormonal, endoscopic, and/or surgical treatment. Conclusions: Ureteral endometriosis represents a diagnostic and therapeutic challenge for the clinicians and high clinical suspicion is needed to identify it.

Abstract
The incidence of endometriosis cases involving the urinary system has recently increased, and the bladder is a specific zone where endometriosis is most commonly seen in the urinary system. In the case presented here, a patient presented to the emergency department with the complaint of side pain and was examined and diagnosed with severe hydronephrosis and bladder endometriosis was determined in the etiology. After the patient was pathologically diagnosed, Levonorgestrel-Releasing Intrauterine System (LNG-IUS) was administered to the uterine cavity. At the 12-month follow-up, endometriosis was not observed in the cystoscopy and symptoms had completely regressed. Hydronephrosis may be observed after exposure of the ureter, and silent renal function loss may develop in patients suffering from endometriosis with bladder involvement. For patients with moderate or severe hydronephrosis associated with bladder endometriosis, LNG-IUS application may be separately and successfully used after conservative surgery.

Abstract
In the past decades, a lot of advances in understanding the biochemistry and physiology of the pineal gland have been made. There is evidence that it interacts with many endocrine as well as non-endocrine tissues to influence their metabolic activity modulating many organs and functions. Melatonin is secreted by the pineal gland in the brain and plays an important role in regulating the neuroendocrine system. This hormone is one of the major role players in the regulation of the circadian sleep-wake cycle. It is normally released from the pineal gland during the night in response to environmental changes in light. Studies have shown that melatonin plays a role in the regulation of many reproductive processes such as puberty, gonadal function, and pregnancy. Beside these, melatonin has been shown to be able to directly neutralize a number of free radicals and reactive oxygen and nitrogen species. The main objective of this review is to provide comprehensive information about the new developments in melatonin research regarding its role in reproduction. A review of international scientific literature was done and a question-and-answer format was used in an attempt to convey comprehensive information in a simple manner. This review discusses evidence currently available relating to the effect of melatonin on reproductive processes. It deliberates the mechanism of action of melatonin, its effect on puberty, testicular and ova function, pregnancy, and oxidative stress. A growing body of scientific evidence is suggesting that melatonin plays an important role in reproductive function. It is therefore imperative to highlight the beneficial effects of this hormone in improving the reproductive processes.

Abstract
To investigate the impact of a 3 months preoperative administration of an oral contraceptive, containing dienogest (DNG) and estradiol valerate (E₂V) on the outcome of office operative hysteroscopy (OOH). One-hundred and forty-two patients diagnosed at office hysteroscopy as having an asynchronous endometrium associated with either a broad-base sessile endometrial polyp (>1.5, <2.5 cm) or a uterine septum (>1/3 uterine cavity) or scheduled for tubal sterilization were enrolled into a prospective case-control study at University "Federico II" of Naples. 86/142 patients accepted the preoperative hormonal treatment (Group A), while 56/142 refused, thus becoming controls (Group B). Group A underwent OOH during the 10th-20th days of the third cycle of treatment. In Group B OOH was performed at enrolment, together with the diagnostic procedure. The study outcomes were: endometrial pattern, success rate, operating time, degree of surgical difficulty and pain score. An overall improvement of the endometrium was reported in 100% of cases in Group A. A statistically significant difference in success rate could not be demonstrated between two groups. Operative procedures were performed significantly quicker and easier in Group A than Group B (p < 0.001 and p < 0.05, respectively). The mean Visual Analog Scale (VAS) score was significantly lower in Group A (p < 0.001). A short pretreatment with combined oral contraceptive (COC) containing E₂V/DNG seems to have a favorable impact on endometrium which in turn may result in an improvement of the overall outcomes of OOH.

Abstract
BACKGROUND The bladder is the most common affected site in urinary tract endometriosis, being diagnosed during gynecologic follow-up. The surgical urological treatment might lead to good results. STUDY OBJECTIVE To define the state of the art in the diagnosis and treatment of bladder endometriosis. METHODS We performed a literature review by searching the MEDLINE database for articles published between 1996 and 2011, limiting the searches to the words: urinary tract endometriosis, bladderendometriosis, symptoms, diagnosis and treatment. RESULTS Deep pelvic endometriosis usually involves the urinary system, with the bladder being affected in 85% of cases. The diagnosis has to be considered as a step-by-step procedure. Currently, the treatment is usually surgical, consisting of either transurethral resection or partial cystectomy, and eventually associated with hormonal therapy. The hormonal therapy alone counteracts only the stimulus of endometriotic tissue proliferation, with no effects on the scarring caused by this tissue. The overall recurrence rate is about 30% for combined therapies and about 35% for the hormonal treatment alone. CONCLUSIONS The bladder is the most common affected site in urinary tract endometriosis. Most of the time, this condition is diagnosed because of the complaint of urinary symptoms during gynecologic follow-up procedures for a deep pelvic endometriosis: a close collaboration between the gynecologist and the urologist is advisable, especially in highly specialized centers. The surgical urological treatment might lead to good results in terms of patients' compliance and prognosis.

Abstract
Approaches to the treatment of endometriosis vary worldwide, but studies comparing endometriosis medications in different ethnic groups are rare. A systematic literature search identified two studies directly comparing dienogest (DNG) versus gonadotropin-releasing hormone (GnRH) analogues in European and Japanese populations. Meta-analysis of visual analogue scale scores revealed no heterogeneity in response between the trials, indicating equivalent efficacy of DNG and GnRH analogues for endometriosis-related pain across populations. DNG was significantly superior to GnRH analogues for bone mineral density change in both trials, but significant heterogeneity between the studies may indicate ethnic differences in physiology.

Abstract
Melatonin (N-acetyl-5-methoxytryptamine) is secreted during the dark hours at night by pineal gland, and it regulates a variety of important central and peripheral actions related to circadian rhythms and reproduction. It has been believed that melatonin regulates ovarian function by the regulation of gonadotropin release in the hypothalamus-pituitary gland axis via its specific receptors. In addition to the receptor mediated action, the discovery of melatonin as a direct free radical scavenger has greatly broadened the understanding of melatonin's mechanisms which benefit reproductive physiology. Higher concentrations of melatonin have been found in human preovulatory follicular fluid compared to serum, and there is growing evidence of the direct effects of melatonin on ovarian function especially oocyte maturation and embryo development. Many scientists have focused on the direct role of melatonin on oocyte maturation and embryo development as an anti-oxidant to reduce oxidative stress induced by reactive oxygen species, which are produced during ovulation process. The beneficial effects of melatonin administration on oocyte maturation and embryo development have been confirmed by in vitro and in vivo experiments in animals. This review also discusses the first application of melatonin to the clinical treatment of infertile women and confirms that melatonin administration reduces intrafollicular oxidative damage and increase fertilization rates. This review summarizes our recent works and new findings related to the reported beneficial effects of melatonin on reproductive physiology in its role as a reducer of oxidative stress, especially on oocyte maturation and embryo development.

Abstract
Endometriosis is a chronic disease primarily affecting women of childbearing age, in which endometriotic lesions form outside the uterus, typically leading to painful symptoms, fatigue, and infertility. The symptoms of endometriosis may cause significant impairment in quality of life and represent a substantial economic burden to patients, families, and society. There is no cure for endometriosis; management consists of alleviating pain and other symptoms, reducing endometriotic lesions, and improving quality of life. Recurrence after surgical intervention is common, while the clinical evidence to support the efficacy and safety of many medications currently used in endometriosis is limited. Dienogest is an oral progestin that has been investigated extensively in the treatment of endometriosis in two clinical programs performed in Europe and Japan, including dose-ranging, placebo-controlled, active comparator-controlled, and long-term (up to 65 weeks) studies. These studies demonstrated that dienogest 2 mg daily effectively alleviates the painful symptoms of endometriosis, reduces endometriotic lesions, and improves indices of quality of life. Dienogest showed a favorable safety and tolerability profile in these studies, with predictable adverse effects, high rates of patient compliance, and low withdrawal rates. This review article describes the clinical trial evidence that characterizes the efficacy and safety of dienogest in endometriosis, including two studies characterizing dienogest in long-term use. The relevance of these findings to the management of endometriosis in clinical practice is discussed.

Eur J Obstet Gynecol Reprod Biol 2011; 157:212-6. [PMID: 21474232 DOI: 10.1016/j.ejogrb.2011.03.012] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2010] [Revised: 02/14/2011] [Accepted: 03/07/2011] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To examine whether long-term administration of dienogest following gonadotropin-releasing hormone agonist (GnRH-a) therapy would prolong the relief of pelvic pain while reducing the amount of irregular uterine bleeding. STUDY DESIGN This was a prospective, non-randomized clinical trial. Among the patients suffering from chronic pelvic pain associated with recurrent endometriosis, Group G (n=38) received GnRH-a for 4-6 months and then dienogest (1 mg/day) for 12 months. The dose of dienogest was increased to 1.5 or 2 mg/day when a patient had uncontrollable uterine bleeding {n=15 (39%)}. Group D (n=33) received only dienogest (2 mg/day) for 12 months. Pelvic pain was assessed using a visual analog scale (VAS). Uterine bleeding was semi-quantified using a pictorial blood loss assessment chart (PBAC). RESULTS In Group G, GnRH-a significantly reduced the VAS score for pelvic pain, and alleviation was maintained during the 12-month therapy with dienogest. There was no significant difference in pain reduction between Group G and Group D. The PBAC score during the first 6 months on dienogest was significantly smaller in Group G than in Group D. CONCLUSION Treatment with a GnRH-a followed by long-term dienogest therapy maintains the relief of endometriosis-associated pelvic pain achieved with GnRH-a therapy for at least 12 months. This regimen reduces the amount of irregular uterine bleeding that often occurs during the early phase of dienogest therapy.

Abstract
Prostaglandin E(2) (PGE(2)) is a major mediator in the pathophysiology, and pathogenesis of gynecological diseases associated with abnormal endometrial disease with proliferation and inflammation, such as endometriosis. In this study, we investigated the effect of dienogest, a selective progesterone receptor agonist, on PGE(2) production and the expression of aromatase, an estrogen synthase, in human immortalized endometrial epithelial cells. Compared with monolayer culture, the cells showed enhanced PGE(2) production and expression of the PGE(2) synthases cyclooxygenase-2 (COX-2), and microsomal prostaglandin E(2) synthase-1 (mPGES-1) in a spheroid culture system. Dienogest inhibited PGE(2) production and this effect was reversed by RU486, a progesterone receptor antagonist. Dienogest inhibited the PGE(2) synthases mRNA and protein expression, and the nuclear factor-κB activation. Moreover, the suppressive effect of dienogest on PGE(2) production was sustained 24h after the drug was withdrawn. Dienogest but not COX inhibitors inhibited aromatase expression. These results suggest that progesterone receptor activation reduces the gene expressions of COX-2, mPGES-1, and aromatase. Our findings suggest that the pharmacological mechanism of dienogest includes the direct inhibition of PGE(2) synthase and aromatase expression and may contribute to the therapeutic effect on the progression of endometriosis.

Abstract
PURPOSE Uterine leiomyomas are the most common benign tumors of reproductive age women, but there is no effective medical therapy to data. Aim of this study was to examine and compare the efficacy of gonadotropin-releasing hormone agonist (GnRHa) versus dienogest in premenopausal women with uterine myoma. METHODS We retrospectively analyzed the medical records of 55 premenopausal patients with endometriosis, who received dienogest (2 mg daily) for 6 months regarding coexistence of uterine myoma between January 2008 and June 2010. To compare these data in a case-control study, we analyzed a matched control group of 12 patients treated with leuprolide acetate (1.88 mg monthly) for 6 months having uterine myoma. RESULTS Of the 55 patients treated with dienogest, six were associated with coexistent myoma node. Total myoma volume significantly decreased to 59.7 ± 7.0% of initial in dienogest group and 51.9 ± 5.5% in GnRHa group. Reduction rate in myoma volume was similar in both groups. CONCLUSION Uterine myoma volume was successfully reduced by use of dienogest. Consideration of GnRHa disadvantages may lead to short- or long-term management of women with myoma who are to be managed transiently, and who wish to avoid surgical intervention, especially perimenopausal women.

Abstract
OBJECTIVE To investigate the efficacy and safety of oral dienogest 2mg compared with placebo in the treatment of endometriosis-associated pelvic pain (EAPP). STUDY DESIGN This was a 12-week, randomized, double-blind, placebo-controlled, multicenter (n=33) study in Germany, Italy, and Ukraine of 198 women aged 18-45 years with laparoscopically confirmed endometriosis and EAPP score > or =30 mm on a visual analog scale (VAS). Dienogest 2mg or placebo was administered orally once daily. The primary efficacy variable was absolute change in EAPP from baseline to Week 12, as determined by the target variables of change in VAS score and change in intake of supportive analgesic medication (ibuprofen) for pelvic pain. RESULTS Mean reductions in VAS score between baseline and Week 12 in the full analysis set were 27.4 mm and 15.1mm in the dienogest and placebo groups, respectively-a significant score difference of 12.3 mm in favor of dienogest (P<0.0001). Changes in intake of supportive analgesic medication were modest in both groups. The primary efficacy measure of absolute change in EAPP demonstrated the superiority of dienogest over placebo. Dienogest was generally well tolerated and few adverse events were associated with therapy. CONCLUSIONS Dienogest at a dose of 2mg daily for 12 weeks was significantly more effective than placebo for reducing EAPP.

Abstract
Dienogest (DNG), a progestin of 19-nortestosterone derivative, has good oral bioavailability and is highly selective for progesterone receptors. Owing to its antiovulatory, antiproliferative activities in endometrial cells, and its inhibitory effects on the secretion of cytokines, DNG is expected to be an effective treatment for endometriosis. Progesterone receptor-binding affinity is higher for DNG than for progesterone. Several pilot studies demonstrated that after 24 weeks of DNG treatment, there was a significant decrease in terms of dysmenorrhea, premenstrual pain, dyspareunia and diffuse pelvic pain. Most of the cases of genital bleeding occurring in the DNG treatment were spotting or breakthrough bleeding, which decreased with continued treatment and resolved either during treatment or after the end of treatment. The therapeutic effects of DNG 2 mg/day and norethisterone acetate 10 mg/day for endometriotic symptoms during a period of 24 weeks were almost similar. The only disadvantage of DNG seems to be the irregular bleeding. Good efficacy and tolerability of DNG in patients with endometriosis have been demonstrated in an open, randomized European clinical trial as compared with norethisterone acetate. In Japan, a Phase III, randomized, double-blind, multicenter, controlled trial was conducted to compare the efficacy and safety of DNG with intranasal buserelin acetate in patients with endometriosis. The study demonstrated that DNG is as effective as intranasal buserelin acetate in alleviating endometriosis symptoms, and causes less bone mineral density loss, resulting in the use on a commercial basis for endometriosis patients in Japan from 2008. This paper provides summarized data on this new promising drug for endometriosis.

Abstract
OBJECTIVES To compare the efficacy and safety of dienogest at doses of 1, 2, and 4mg/day orally in the treatment of endometriosis. METHODS An open-label, randomized, multicenter, 24-week comparative trial in women with histologically confirmed endometriosis. Efficacy was assessed by second-look laparoscopy and patient-reported symptoms. Statistical tests included chi(2) and Wilcoxon signed rank tests. RESULTS Dienogest reduced mean revised American Fertility Society scores from 11.4 to 3.6 (n=29; P<0.001) in the 2-mg group and from 9.7 to 3.9 (n=35; P<0.001) in the 4-mg group. Dienogest at 2 and 4mg/day was associated with symptom improvements in substantial proportions of women. Both dienogest doses were generally well tolerated, with low rates of treatment discontinuation due to adverse events. The 1-mg dose arm was discontinued owing to insufficient bleeding control. CONCLUSION Dienogest at 2mg once a day is recommended as the optimal dose in future studies of endometriosis.

Abstract
Dienogest (DNG) has the essential properties of an effective progestogen for use in a new contraceptive pill using estradiol valerate as estrogenic component -- it inhibits ovulation and protects against endometrial proliferation. DNG is a derivative of norethisterone (NET), but has a cyanomethyl- instead of an ethinyl-group in C17 position which may offer a variety of benefits regarding hepatic effects. The similarity to NET is reflected in the high endometriotropy and in similar pharmacokinetics like short plasma half-live and high bioavailability. However, DNG also elicits properties of progesterone derivatives like neutrality in metabolic and cardiovascular system and considerable antiandrogenic activity, the latter increased by lack of binding to SHBG as specific property of DNG. It has no glucocorticoid and antimineralocorticoid activity and has no antiestrogenic activity with the consequence that possible beneficial estradiol effects should not be antagonized. This may be of special importance for the tolerability and safety of the first pill with estradiol valerate instead of ethinylestradiol, although well-designed postmarketing studies are still ongoing to demonstrate what can be expected on the basis of pharmacology.

Abstract
BACKGROUND Dienogest is a selective progestin that has been investigated in a clinical trial programme for the treatment of endometriosis. The current non-inferiority trial compared the efficacy and safety of dienogest against leuprolide acetate (LA) for treating the pain associated with endometriosis. METHODS Patients with confirmed endometriosis were randomized to treatment with dienogest (2 mg/day, orally) or LA (3.75 mg, depot i.m. injection, every 4 weeks) for 24 weeks. The primary efficacy variable was absolute change in pelvic pain from baseline to end of treatment, assessed by visual analogue scale (VAS). Safety variables included adverse event profile, laboratory parameters, bone mineral density (BMD), bone markers and bleeding patterns. RESULTS A total of 252 women were randomized to treatment with dienogest (n = 124) or LA (n = 128); 87.9 and 93.8% of the respective groups completed the trial. Absolute reductions in VAS score from baseline to Week 24 were 47.5 mm with dienogest and 46.0 mm with LA, demonstrating the equivalence of dienogest relative to LA. Hypoestrogenic effects (e.g. hot flushes) were reported less frequently in the dienogest group. As expected, bleeding episodes were suppressed less with dienogest than with LA. Changes in mean lumbar BMD between screening and final visit were +0.25% with dienogest and -4.04% with LA subgroups (P = 0.0003). Markers of bone resorption increased with LA but not dienogest. CONCLUSIONS Dienogest 2 mg/day orally demonstrated equivalent efficacy to depot LA at standard dose in relieving the pain associated with endometriosis, although offering advantages in safety and tolerability.

Abstract
PURPOSE Hormonal treatment of endometriosis is often continued for long periods and has the potential to affect many essential metabolic processes. The current study aimed to determine the effects and safety of high-dose dienogest as a medical endometriosis therapy. METHODS The effects and safety of high-dose dienogest, 20-30 mg/day for 24 weeks, were examined in 21 women aged 18-52 years with laparoscopically and histologically proven endometriosis stage I-IV (according to revised American Society of Reproductive Medicine criteria). At baseline and week 24, sera were obtained and stored at -20°C prior to analysis. RESULTS The study showed no clinically significant effect of high-dose dienogest on thyroid or adrenal function, electrolyte balance or haematopoiesis. High-dose dienogest therapy also had no appreciable effects on glucose and lipid metabolism, liver enzymes or haemostasis. For instance, although dienogest mediated small increases in the haemostatic variables prothrombin fragment 1 + 2, antithrombin III and protein C, final levels (at week 24) remained within normal reference ranges for these parameters. The exception was the HDL-3 cholesterol concentration at week 24 (0.97 mmol/l), which increased beyond the normal range of 0.28-0.64 mmol/l. CONCLUSIONS This investigation yielded a unique dataset on the safety of high-dose dienogest in endometriosis stage I-IV. High-dose dienogest (20-30 mg/day) had little influence upon all the parameters measured. It is therefore likely that lower doses of dienogest would have similarly neutral safety effects: an important consideration in the use of dienogest for the treatment of endometriosis.

Abstract
OBJECTIVE To develop a universal guideline allowing the comparison of interventions like oral contraceptives and hormone replacement therapy with an impact on menstrual bleeding pattern. METHODS Literature analysis and cluster analysis of 4612 bleeding diaries. RESULTS We summarized key definitions needed for the evaluation of menstrual bleeding patterns from the literature. We developed a methodology to systematically evaluate menstrual bleeding patterns that distinguishes between cyclical and continuous hormonal regimens. CONCLUSION This universal guideline can be applied to all prospective clinical studies that affect menstrual bleeding patterns. It allows regulatory agencies and prescribing physicians to make meaningful comparisons of different products.

Abstract
In a clinical pilot study, 21 women with endometriosis have been primarely treated with dienogest 2 x 10 mg daily p.o. for 24 weeks. Besides the effect on endometriosis the action of such high-dose progestogen treatment on the breast was evaluated by breast ultrasound prior to medication and at 24 weeks of medical treatment. In all women, a significant size reduction of the mammary gland (p < 0.023) and regression of mastopathic changes were observed. There was a non-significant reduction (p = 0.089) of the maximum diameter of the ducts. The portion of the fatty tissue increased slightly, but not significantly (p = 0.348).

Abstract
Dienogest is a specific progesterone receptor agonist with potent oral endometrial activity and is used in the treatment of endometriosis. In this study, we examined the direct effects of dienogest on the proliferation of human endometrial epithelial cells using an immortalized cell line. 5-Bromo-2'-deoxyuridine incorporation into the cells was inhibited by dienogest and by progesterone (P(4)) in dose-dependent fashion at concentrations of 10(-8) mol/l or higher. To identify the target genes of dienogest and P(4), we screened the expression of 84 genes related to cell cycle regulation by real-time polymerase chain reaction after 6 h of treatment at a concentration of 10(-7) mol/l. Results showed that only cyclin D1 expression was significantly down-regulated, although expression of the other genes did not significantly change after dienogest or P(4) treatment compared with the control. In a time-course study during the first 24 h after drug treatment, dienogest and P(4) each produced a lasting decrease in the expression of cyclin D1 mRNA, followed by a decrease in cyclin E1 mRNA but not an increase in the expression of cell cycle inhibitor genes (p21, p27 and p53). These findings suggest that dienogest directly inhibits the proliferation of human endometrial epithelial cells with suppression of cyclin D1 gene expression.

Abstract
Dienogest was introduced as an oral progestin. Yet its strong oral potency on endometrial activity is not clearly explained. To circumvent this situation, steroid hormone receptor profiling using transactivation assay and endometrial activity test in rabbits were carried out with determination of plasma drug concentration. Agonistic/antagonistic activity on human progesterone receptor (PR), androgen receptor (AR), glucocorticoid receptor (GR), mineralocorticoid receptor (MR), estrogen receptor alpha (ERalpha), or estrogen receptor beta (ERbeta) were determined. Dienogest activate PR (EC50=3.4 or 10.5 nmol/l) with antagonistic activity on AR (EC50=420.6 or 775.0 nmol/l) but not agonistic nor antagonistic action on GR, MR (3000 nmol/l). Dienogest activate neither ERalpha nor ERbeta (3000 nmol/l). Progesterone activated PR with antagonistic activity on AR and on MR. Dydrogesterone showed a similar profile to progesterone. Norethisterone activated PR, AR, and ERalpha. Medroxyprogesterone acetate activated PR, AR, and GR. Danazol activated PR and AR. Collectively, dienogest has a good specificity to PR compared with the other drugs. By oral treatment, dienogest showed the strongest endometrial activity (ED50=0.0042 mg/kg) in McPhail test among other progestins (ED50 values for MPA, DYG, NES were 0.074, 1.9, >0.05 mg/kg, respectively). Dienogest showed higher plasma concentrations than those of the other progestins with higher doses. The estimated plasma concentration of dienogest at ED50 (3.66 nmol/l) was close to its EC50 value to activate PR. Thus, the stronger oral activity of dienogest could be explained simply by its in vitro potency on PR and its oral pharmacokinetic profile.

Abstract
PURPOSE OF REVIEW To appraise a new approach to laparoscopic surgery for infertility caused by advanced endometriosis. RECENT FINDINGS Endometriosis is a common systemic and local disease with altered peritoneal function, which requires both systemic and local treatment. Medication alone cannot improve infertility, and laparoscopic treatment, particularly in severe endometriosis, has a high recurrence rate and is often limited by technical difficulties. Novel treatment strategies have therefore to be sought, especially in women who do not want in-vitro fertilization as a first option, either because they suffer from pain in addition to infertility or want to enhance their fertility over many cycles. SUMMARY Two-step operative laparoscopy with interval pituitary suppression by means of gonadotrophin-releasing hormone analogues reduces the extent of endometriosis, as classified by the American Fertility Association, and appears to be a promising method of achieving optimal cytoreduction and facilitating complicated surgery in severe endometriosis, while protecting the ovary from unnecessary trauma. A large-scale well-designed study is needed to confirm that this treatment leads to improved pregnancy rates.

Abstract
OBJECTIVE To investigate the effect of dienogest on the proliferation of endometriotic stromal cells. DESIGN Comparative and laboratory study. SETTING University of Tokyo Hospital. PATIENT(S) Endometriotic stromal cells were isolated and cultured from ovarian endometriomas of patients undergoing surgery. INTERVENTION(S) Dienogest was added to the cultured endometriotic stromal cells. MAIN OUTCOME MEASURE(S) 5-Bromo-2'-deoxyuridine (BrdU) incorporation into DNA of the endometriotic stromal cells was measured by ELISA. Cell cycle analysis of the cultured endometriotic stromal cells was performed by flow cytometry. RESULT(S) Dienogest at concentration of 10(-7) M and 10(-6) M significantly inhibited BrdU incorporation into DNA at 24 and 48 hours. Dienogest significantly increased the cells in G0/G1 phase and reduced the cells in S phase and G2/M phase in 24 and 48 hours. CONCLUSION(S) The present study indicates that dienogest can inhibit the proliferation of the endometriotic stromal cells with G0/G1 arrest, suggesting a possible direct effect of dienogest in the treatment of endometriosis.

Abstract
Endometriosis is a common, estrogen-dependent, gynaecological disease, defined as the presence of endometrial-like tissue outside the uterus. Although several medications are used for treatment of the disease, they are associated with high recurrence rates, considerable side effects and limited duration of application. Due to these limitations and to the impact of endometriosis on the quality of life of affected women, their environment and the society, there is a great need for new drugs able to abolish endometriosis and its symptoms. Studies in recent years investigating the (patho)physiological mechanisms involved in disease aetiology have fostered the development of novel therapeutic concepts for endometriosis, by targeting the hypothalamic-pituitary-gonadal axis, by selective modulation of estrogenic and progestogenic pathways, by inhibiting angiogenesis or by interfering with inflammatory and immunological factors. This article presents a brief summary of the currently available medications and an overview regarding the development of some of the most interesting and/or most promising novel drug candidates for endometriosis.
