Abstract
OBJECTIVE The objective of this work is to evaluate the place of new treatments in the management of endometriosis outside the context of infertility. METHODS A review of the literature was conducted by consulting Medline data until July 2017. RESULTS Dienogest is effective compared to placebo in short term (NP2) and long term (NP4) for the treatment of painful endometriosis. In comparison with GnRH agonists, dienogest is also effective in terms of decreased pain and improved quality of life in non-operated patients (NP2) as well as for recurrence of lesions and symptomatology postoperatively (NP2). Data on GnRH antagonists, selective progesterone receptor modulators as well as selective inhibitors (anti-TNF-α, matrix metalloprotease inhibitors, angiogenesis growth factor inhibitors) are insufficient to provide evidence of interest in clinical practice for the management of painful endometriosis (NP3). CONCLUSION Dienogest is recommended as second-line therapy for the management of painful endometriosis (Grade B). Because of lack of evidence, aromatase inhibitors, elagolix, SERM, SPRM and anti-TNF-α are not recommended for the management of painful endometriosis (Grade C).

Abstract
In the past years, individualization of assisted reproductive technique (ART)-treatment is increasingly common to customize the treatment protocol to the patient's specific conditions. The use of GnRH-agonist for final oocyte maturation in a gonadotropin-releasing hormone (GnRH)-antagonist protocol is the best approach to reduce the risk for ovarian hyperstimulation in high responder patients. However, due to severe luteolysis, the reproductive outcome with this approach in combination with the use of vaginal progesterone as luteal phase support, was poor. Cycle segmentation as alternative to a fresh transfer requires embryo freezing which might not be applicable to all patients due to various reasons. The concept of luteal coasting monitors the progesterone-level closely and human chorionic gonadotropin (hCG) for rescue of the corpora lutea is administered when the progesterone-level drops below a certain threshold. However, the lower range of progesterone levels in the early luteal phase after GnRH-agonist trigger, which is compatible with achieving and maintaining a pregnancy, is unknown. This case-series demonstrates, that ongoing pregnancies can be achieved even with a progesterone-level below 15 ng/ml in the early luteal phase with the timely administration of an hCG-rescue bolus. With the concept of luteal coasting, individualization of the luteal phase support according to the patient's specific luteolysis pattern is possible.

Abstract
Although early breast cancer (BC) is highly curable, advanced or metastatic disease poses numerous challenges in terms of medical management and treatment decisions and is associated with significantly worse prognosis. Among the new targeted agents, anticancer drugs exploiting the cell-cycle machinery have shown great potential in preclinical studies. CDK4/6 inhibitors target the cyclin D/CDK/retinoblastoma signaling pathway, inducing cell-cycle arrest, reduced cell viability and tumor shrinking. As the cyclin D/CDK complex is activated downstream of estrogen signaling, the combination of CDK4/6 inhibitors with standard endocrine therapies represents a rational approach to elicit synergic antitumor activity in hormone receptor-positive BC. The results of clinical trials have indeed confirmed the superiority of the combination of CDK4/6 inhibitors plus endocrine therapies over endocrine therapy alone. Currently approved are three compounds that exhibit similar structural characteristics as well as biological and clinical activities. Abemaciclib is the latest CDK4/6 inhibitor approved by the US Food and Drug Administration (FDA) in view of the results of the MONARCH 1 and 2 trials. Further trials are ongoing as other important questions await response. In this review, we focus on abemaciclib to examine preclinical and clinical results, describing current therapeutic indications, open questions and ongoing clinical trials.

Abstract
AIM We studied externally controlled anticancer effects of binding tumor growth inhibiting synthetic peptides to magnetoelectric nanoparticles (MENs) on treatment of glioblastomas. METHODS Hydrothermally synthesized 30-nm MENs had the core-shell composition of CoFe2O4@BaTiO3. Molecules of growth hormone-releasing hormone antagonist of the MIA class (MIA690) were chemically bound to MENs. In vitro experiments utilized human glioblastoma cells (U-87MG) and human brain microvascular endothelial cells. RESULTS The studies demonstrated externally controlled high-efficacy binding of MIA690 to MENs, targeted specificity to glioblastoma cells and on-demand release of the peptide by application of d.c. and a.c. magnetic fields, respectively. CONCLUSION The results support the use of MENs as an effective drug delivery carrier for growth hormone-releasing hormone antagonists in the treatment of human glioblastomas.

Abstract
Glucocorticoids influence a wide range of metabolic processes in the human body, and excessive glucocorticoid exposure is known to contribute to the development of metabolic disease. We evaluated the utility of the novel glucocorticoid receptor (GR) antagonist CORT125281 for its potential to overcome adiposity, glucose intolerance, and dyslipidemia and compared this head-to-head with the classic GR antagonist RU486 (mifepristone). We show that, although RU486 displays cross-reactivity to the progesterone and androgen receptor, CORT125281 selectively inhibits GR transcriptional activity. In a mouse model for diet-induced obesity, rhythmicity of circulating corticosterone levels was disturbed. CORT125281 restored this disturbed rhythmicity, in contrast to RU486, which further inhibited endogenous corticosterone levels and suppressed adrenal weight. Both CORT125281 and RU486 reduced body weight gain and fat mass. In addition, CORT125281, but not RU486, lowered plasma levels of triglycerides, cholesterol, and free fatty acids and strongly stimulated triglyceride-derived fatty acid uptake by brown adipose tissue depots. In combination with reduced lipid content in brown adipocytes, this indicates that CORT125281 enhances metabolic activity of brown adipose tissue depots. CORT125281 was also found to increase liver lipid accumulation. Taken together, CORT125281 displayed a wide range of beneficial metabolic activities that are in part distinct from RU486, but clinical utility may be limited due to liver lipid accumulation. This warrants further evaluation of GR antagonists or selective modulators that are not accompanied by liver lipid accumulation while preserving their beneficial metabolic activities.

Abstract
OBJECTIVE To compare the results of ovarian stimulation with LH surge blockade by medroxyprogesterone acetate or GnRH antagonist in oocytes donors. To present current options of exogenous and endogenous progestins instead of GnRH analogues to block LH surge during ovarian stimulation. DESIGN Retrospective study of oocyte donor cycles and literature review. SETTING Department of Obstetrics and Gynecology, Faculty of Medicine, Masaryk university and University Hospital Brno. METHODS Thirteen oocyte donors (26.8 ± 2.5 years old) were stimulated with recFSH and MPA to block the LH surge during January - October 2017. The results were compared to the previous cycle stimulated with recFSH and GnRH antagonist performed during January -December 2016. Wilcoxon´s pair test was used to test the statistics. A literature search of SCOPUS was carried out. RESULTS In cycles with MPA blockade the average number of oocytes was 14.5 ± 5.1, in cycles with GnRH anta-gonist blockade 12.0 ± 4.5 oocytes (statistical significance p = 0.025). FSH total dose (1611 ± 327 vs. 1565 ± 322 IU), days of stimulation (9.1 ± 0.8 vs. 8.5 ± 0.9) and maximum estradiol levels (5.9 ± 2.1 vs. 6.0 ± 3.0 nmol/l) were not statistically different. Progestins are effective in blocking the LH surge during ovarian stimulation and do not affect the number and quality of collected oocytes or obtained embryos. Their adverse effect on the endometrial receptivity obstructs the embryo implantation in the same cycle. Such protocol requires total freezing and delayed transfer. Progestins can be used in a variety of stimulation protocols - progestin primed follicular phase stimulation, luteal phase stimulation with endogenous progesteron, double stimulation in follicular and luteal phase of the same cycle "duostim" in low responders. CONCLUSION Eggs donor ovarian stimulation with MPA resulted in more oocytes than stimulation protocol with GnRH antagonist, the total dose of FSH and the length of stimulation were similar. According to current experiences progestins effectively block the LH surge and do not affect the number and quality of collected eggs and obtained embryos. Their use opens new possibilities of ovarian stimulation protocols and their flexibility. Its main constraint is that it requires total freezing and delayed transfer.

Abstract
CONTEXT Testotoxicosis is an autosomal-dominant, male-limited disorder. Activating mutations in the luteinizing hormone receptor gene (LHCGR) cause high autonomous testosterone secretion, resulting in early-onset peripheral precocious puberty. Little is known about long-term consequences of testotoxicosis. CASE DESCRIPTION We present a rare case of a patient followed for 25 years with two remarkable outcomes: preserved fertility and germ cell neoplasia in situ (GCNIS). He presented with precocious puberty at 10 months of age and was diagnosed with testotoxicosis due to a de novo heterozygous Asp578Tyr mutation in LHCGR. Testicular biopsy in childhood showed Leydig cell hyperplasia with altered cell maturation. From infancy throughout adulthood, elevated testosterone and estradiol, low inhibin B and anti-Müllerian hormone, and completely suppressed follicle-stimulating hormone and luteinizing hormone were noted. Height acceleration and advanced bone age resulted in a reduced final height. Semen analysis revealed ongoing spermatogenesis, and the patient fathered a child by natural conception. Ketoconazole treatment decreased circulating testosterone in childhood, supported by experimental suppression of testosterone production in his adult testis tissue cultured ex vivo. At 25 years of age, ultrasound revealed a testicular tumor, identified as a Leydig cell adenoma, but unexpectedly with GCNIS present in adjacent seminiferous tubules. CONCLUSION The case illustrates that absence of gonadotropins but high intratesticular testosterone concentration is sufficient for spermatogenesis and to allow fatherhood. Our study is also the first description, to our knowledge, of GCNIS in a patient with testotoxicosis. We recommend regular clinical examination and ultrasonic evaluation of the testes in these patients due to potential increased risk of malignancy.

Abstract
CYCLIC AND NON-CYCLIC BREAST-PAIN A systematic review on pain reduction, side effects, and quality of life for various treatments. BACKGROUND No clear systematic-review on all the various treatment regimen for (Non-) cyclical-breast-pain currently exists. OBJECTIVES The aim of this study was to assess the various forms of therapy for treatment of breast-pain and the evidence for their effectiveness. SEARCH STRATEGY Search-terms included 'mastalgia' and 'therapy' or 'hormones' or 'nsaid' or 'psychotherapy' or 'analgesia' or 'surgery', and synonyms. SELECTION CRITERIA The review was conducted according to the Preferred Reporting Items for Systematic-reviews and Meta-Analysis guidelines. RCT's and pro-/retrospective studies reporting on treatment of breast-pain were considered eligible. Minimal follow-up and sample-size criteria were 6 months and 10 patients respectively. DATA COLLECTION AND ANALYSIS Data was extracted using standardized tables and encompassed number of subjects, type of breast-pain and treatment, efficacy of treatment and clinical complications/side-effects. No pooling of data could be achieved due to heterogeneity amongst studies. MAIN RESULTS Twenty-three studies were included, that reported on 2100 patients in total. Topical-Diclofenac was found to reduce pain by 58.7 and 63.3 on a Visual-Analogue-Scale (VAS) in cyclical and non-cyclical-breast-pain respectively. Persistent cyclical-breast-pain can be treated with short courses (2-6 months) of either Bromocryptine (VAS↓=25.4) or Danazol (VAS↓=33.6) as long as benefits outweigh the side-effects. Last-resort options for unresponsive and severe debilitating breast-pain include surgery in the form of bilateral mastectomy with reconstruction. CONCLUSIONS Pain reduction in patients with breast-pain can be achieved with analgesics, hormonal-regimen and possibly surgery as a last resort. Additional studies are needed with well-described patient-characteristics, robust study set-up, and longer follow-up times.

Abstract
To compare the therapeutic efficacy of clomiphene citrate (CC) and letrozole (LE) on ovulation, pregnancy, and live birth in women with polycystic ovary syndrome (PCOS); and to ensure if LE can replace CC as the first-line therapy for ovulation induction in these women. This is a prospectively, randomized, controlled trial in the tertiary hospital. Two-hundred and sixty-eight anovulatory PCOS patients were treated by CC or CC plus metformin and LE or LE plus metformin for three continuous cycles or conception; their ovulation rates, pregnancy rates, and live birth rates were calculated and compared. No significant difference was noted among the four groups regarding to the baseline data of clinical manifestations, serum sex hormone levels, and serum insulin levels. A total of 240 patients completed the therapies. The ovulation rate was significantly higher in the group LE than the group CC; however, no significant difference was noted between the groups LE and CC, CC, and CC + MET, or LE and LE + MET in the pregnancy rate, abortion rate, and live birth rate. No birth defect was found in the total of 63 newborns. CC regimen was still recommended to be the first-line therapy of ovulation induction for PCOS.

Abstract
RATIONALE Case reports concerning the value of dopamine agonists in the treatment of patients with thyrotropin-secreting pituitary adenoma (TSHoma) are limited. Herein, we present a rare case of octreotide-insensitive TSHoma responding to bromocriptine therapy. PATIENT CONCERNS A 45-year-old Chinese man was admitted to Peking Union Medical College Hospital with marked clinical manifestations of hyperthyroidism. DIAGNOSES Thyroid function tests demonstrated elevated concentrations of free thyroid hormones in the presence of normal thyrotropin. Magnetic resonance imaging findings showed a pituitary microadenoma on the right side of the sellar region. Based on characteristic endocrine results and neuroimaging findings, the patient was diagnosed with TSHoma. INTERVENTIONS Most patients with TSHomas are significantly responsive to somatostatin analog treatment. However, our patient was orally administered with bromocriptine to normalize thyroid function as assessed by suppression tests conducted prior to surgery. A transsphenoidal surgery was performed by an experienced neurosurgeon for tumor removal. OUTCOMES The pituitary lesion was totally resected. Following the operation, the results of thyroid function tests were immediately within reference limits. During the follow-up, there was no residual or recurrent tumor. LESSONS Attention should be paid to the role of dopamine agonists such as bromocriptine and cabergoline as adjuvant therapy for TSHomas that are insensitive to traditional medical treatment by somatostatin analogs.

Abstract
The use of GnRH agonist to trigger final oocyte maturation in GnRH-antagonist in vitro fertilization (IVF) cycles has been shown to significantly reduce or even eliminate the risk of ovarian hyperstimulation syndrome (OHSS) by inducing rapid luteolysis early in the luteal phase. The exact mechanism of this early luteolysis is still widely unknown. Since luteinizing hormone (LH) has a major role in corpus luteum support, we sought to explore the pattern of LH secretion early in the luteal phase. Ten high risk patients for developing OHSS and triggered with GnRH agonist were included. Frequent blood sampling (every 20 min for 6 h) to measure LH, estradiol and progesterone was done on the day of oocyte collection (n = 5, Group 1) and on the day of embryo transfer, 48 h after oocyte collection (n = 5, Group 2). We found that the mean LH concentration and its secretion rate decreased significantly in Group 2 compared to Group 1. Both groups had similar number of LH pulses characterized by very small amplitude. In Group 2, there was a steady significant decrease in estradiol and progesterone over time. The results of this study show that LH secretion deviates significantly from normal physiologic pattern, which can explain, at least in part, the post-GnRH-agonist trigger early luteolysis mechanism.

Abstract
OBJECTIVE The aim of this study is to assess the role of AMH in prediction of poor ovarian response as well as the relation between ESR 2 (+ 1730G>A) (rs4986938) and FSHR p.Thr307Ala (c.919A>G, rs6165) SNPs and the poor ovarian response in Egyptian women undergoing IVF procedure. Discovering the genetic variants associated with ovarian response is an important step towards individualized pharmacogenetic protocols of ovarian stimulation. METHODS We performed a prospective study on 216 young women with unexplained infertility. Ovarian stimulation was performed according to the GnRH antagonist protocol with a fixed daily morning dose of human menopausal gonadotrophin (HMG). The estrogen receptor (ESR2) (+ 1730G>A) (rs4986938) and FSH receptor p.Thr307Ala (c.919A>G, rs6165) single nucleotide polymorphisms (SNPs) were detected by real-time polymerase chain reaction. Serum FSH, Estradiol (E2) and anti-Müllerian hormone (AMH) levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS This study revealed that the low AMH level was highly significantly related to the poor ovarian response (p < 0.001). Furthermore, the frequency of the ESR2 (AA) genotype and the FSHR (Ala307Ala) genotypes were highly significantly associated with the poor ovarian response (p < 0.001). CONCLUSION The AMH level in combination with the ESR2 and the FSHR gene polymorphisms predict the poor ovarian response to COH in Egyptian women.

Abstract
PURPOSE To explore serum endocrine dynamics, specifically LH levels, following rLH supplementation to rFSH following GnRH-antagonist treatment in the advance reproductive age. METHODS Women were prospectively and similarly treated employing rFSH and the flexible GnRH-antagonist protocol, while rLH was supplemented only to the study group. Serum FSH, LH, E2, and P were evaluated throughout the follicular phase. Three strategies were a priori planned to examine endocrine dynamics among women enrolled. RESULTS While serum LH drop were similar before GnRH-antagonist stimulation, it dropped more times in the control group compared to the study group. Among women receiving rFSH only, serum LH levels dropped ≤2, ≤1 and ≤0.5 mIU/mL in 71.4, 46.4, and 28.6% of cases, while this occurred only in 38.7% (P = 0.01), 6.5% (P = 0.0004) and 3.2% (P = 0.007) of women receiving combined rFSH and rLH treatment, respectively. The same trend was found when serum LH dropped in at least two occasions following the GnRH-antagonist administration. Conversely, serum LH diagrams throughout the follicular phase did not differ between the two groups. Furthermore, individual area under the curve values of LH, E2, and P was similar between the two groups following GnRH-antagonist initiation. CONCLUSIONS Different strategies to explore LH dynamics following the GnRH-antagonist administration have resulted in diverse results, implying the need for a consensus definition of LH threshold for adequate folliculogenesis and steroidogenesis. Such action would pave the way for understanding which groups of patients may benefit from rLH supplementation.

Abstract
BACKGROUND Endometriosis is defined as the presence of endometrial tissue (glands and stroma) outside the uterine cavity. This condition is oestrogen-dependent and thus is seen primarily during the reproductive years. Owing to their antiproliferative effects in the endometrium, progesterone receptor modulators (PRMs) have been advocated for treatment of endometriosis. OBJECTIVES To assess the effectiveness and safety of PRMs primarily in terms of pain relief as compared with other treatments or placebo or no treatment in women of reproductive age with endometriosis. SEARCH METHODS We searched the following electronic databases, trial registers, and websites: the Cochrane Gynaecology and Fertility Group (CGFG) Specialised Register of Controlled Trials, the Central Register of Studies Online (CRSO), MEDLINE, Embase, PsycINFO, clinicaltrials.gov, and the World Health Organization (WHO) platform, from inception to 28 November 2016. We handsearched reference lists of articles retrieved by the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) published in all languages that examined effects of PRMs for treatment of symptomatic endometriosis. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as expected by the Cochrane Collaboration. Primary outcomes included measures of pain and side effects. MAIN RESULTS We included 10 randomised controlled trials (RCTs) with 960 women. Two RCTs compared mifepristone versus placebo or versus a different dose of mifepristone, one RCT compared asoprisnil versus placebo, one compared ulipristal versus leuprolide acetate, and four compared gestrinone versus danazol, gonadotropin-releasing hormone (GnRH) analogues, or a different dose of gestrinone. The quality of evidence ranged from high to very low. The main limitations were serious risk of bias (associated with poor reporting of methods and high or unclear rates of attrition in most studies), very serious imprecision (associated with low event rates and wide confidence intervals), and indirectness (outcome assessed in a select subgroup of participants). Mifepristone versus placebo One study made this comparison and reported rates of painful symptoms among women who reported symptoms at baseline.At three months, the mifepristone group had lower rates of dysmenorrhoea (odds ratio (OR) 0.08, 95% confidence interval (CI) 0.04 to 0.17; one RCT, n =352; moderate-quality evidence), suggesting that if 40% of women taking placebo experience dysmenorrhoea, then between 3% and 10% of women taking mifepristone will do so. The mifepristone group also had lower rates of dyspareunia (OR 0.23, 95% CI 0.11 to 0.51; one RCT, n = 223; low-quality evidence). However, the mifepristone group had higher rates of side effects: Nearly 90% had amenorrhoea and 24% had hot flushes, although the placebo group reported only one event of each (1%) (high-quality evidence). Evidence was insufficient to show differences in rates of nausea, vomiting, or fatigue, if present. Mifepristone dose comparisons Two studies compared doses of mifepristone and found insufficient evidence to show differences between different doses in terms of effectiveness or safety, if present. However, subgroup analysis of comparisons between mifepristone and placebo suggest that the 2.5 mg dose may be less effective than 5 mg or 10 mg for treating dysmenorrhoea or dyspareunia. Gestrinone comparisons Ons study compared gestrinone with danazol, and another study compared gestrinone with leuprolin.Evidence was insufficient to show differences, if present, between gestrinone and danazol in rate of pain relief (those reporting no or mild pelvic pain) (OR 0.71, 95% CI 0.33 to 1.56; two RCTs, n = 230; very low-quality evidence), dysmenorrhoea (OR 0.72, 95% CI 0.39 to 1.33; two RCTs, n = 214; very low-quality evidence), or dyspareunia (OR 0.83, 95% CI 0.37 to 1.86; two RCTs, n = 222; very low-quality evidence). The gestrinone group had a higher rate of hirsutism (OR 2.63, 95% CI 1.60 to 4.32; two RCTs, n = 302; very low-quality evidence) and a lower rate of decreased breast size (OR 0.62, 95% CI 0.38 to 0.98; two RCTs, n = 302; low-quality evidence). Evidence was insufficient to show differences between groups, if present, in rate of hot flushes (OR 0.79, 95% CI 0.50 to 1.26; two RCTs, n = 302; very low-quality evidence) or acne (OR 1.45, 95% CI 0.90 to 2.33; two RCTs, n = 302; low-quality evidence).When researchers compared gestrinone versus leuprolin through measurements on the 1 to 3 verbal rating scale (lower score denotes benefit), the mean dysmenorrhoea score was higher in the gestrinone group (MD 0.35 points, 95% CI 0.12 to 0.58; one RCT, n = 55; low-quality evidence), but the mean dyspareunia score was lower in this group (MD 0.33 points, 95% CI 0.62 to 0.04; low-quality evidence). The gestrinone group had lower rates of amenorrhoea (OR 0.04, 95% CI 0.01 to 0.38; one RCT, n = 49; low-quality evidence) and hot flushes (OR 0.20, 95% CI 0.06 to 0.63; one study, n = 55; low quality evidence) but higher rates of spotting or bleeding (OR 22.92, 95% CI 2.64 to 198.66; one RCT, n = 49; low-quality evidence).Evidence was insufficient to show differences in effectiveness or safety between different doses of gestrinone, if present. Asoprisnil versus placebo One study (n = 130) made this comparison but did not report data suitable for analysis. Ulipristal versus leuprolide acetate One study (n = 38) made this comparison but did not report data suitable for analysis. AUTHORS' CONCLUSIONS Among women with endometriosis, moderate-quality evidence shows that mifepristone relieves dysmenorrhoea, and low-quality evidence suggests that this agent relieves dyspareunia, although amenorrhoea and hot flushes are common side effects. Data on dosage were inconclusive, although they suggest that the 2.5 mg dose of mifepristone may be less effective than higher doses. We found insufficient evidence to permit firm conclusions about the safety and effectiveness of other progesterone receptor modulators.

Abstract
BACKGROUND Endometriosis is the presence of functional endometrial tissue in the pelvic peritoneum and it affects several age groups. That is why the impact of endometriosis in quality of life is considerable. The objective of this study was to evaluate the effectiveness of dienogest in patients with pelvic pain associated to endometriosis (PPAE). METHODS The evaluation of the effectiveness was carried out through a systematic review using the Cochrane methodology. It was used Markov model, which considers two states of health (with and without PPAE), with the possibility of weekly transition. Women between 18 and 45 years with PPAE were included, in a temporary horizon of 26 weeks. A level of statistical significance of 95% was used for a p < 0.05, with a multivariate probabilistic analysis of sensibility, as well as a univariate analysis of sensibility in several scenarios. RESULTS The probability that the female patient did not experience PPAE with the initial treatment was 87.91% with dienogest, 80.07% with danazol, 84.93% with medroxyprogesterone (injectable and oral) and 89.17% with gosereline. The probability that the female patient abandoned her initial treatment was 9% with dienogest, 12.07% with danazol, 9.6 and 6.75% with medroxyprogesterone injectable and oral, respectively, and 10.8 and 3.6% 3-monthly and monthly with gosereline. CONCLUSION Compared to danazol, medroxiprogesterone and gosereline, dienogest is the most efficient alternative to treat PPAE.

Abstract
Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a "freeze-all" strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity. However, also a detrimental effect of elevated progesterone on day-3 embryo quality has recently been found with regards to top quality embryo formation rate. Because blastocyst culture and cryopreservation are largely adopted, we deemed relevant to determine whether this detrimental effect is also seen on blastocyst quality on day 5-6. This issue was investigated through a large two-center retrospective study including 986 GnRH antagonist IVF/ICSI cycles and using top quality blastocyst formation rate as the main outcome. Results showed that on multivariate analysis sperm motility (p<0.01) and progesterone levels at ovulation triggering (p = 0.01) were the only two variables that significantly predicted top quality blastocyst formation rate after adjusting for relevant factors including female age, BMI, basal AMH and total dose of FSH used for COS. More specifically, progesterone levels at induction showed an inverse relation with top quality blastocyst formation (correlation coefficient B = -1.08, 95% CI -1.9 to -0.02) and ROC curve analysis identified P level >1.49 ng/ml as the best cut-off for identification of patients at risk for the absence of top quality blastocysts (AUC 0.55, p<0.01). Our study is the first to investigate the top quality blastocyst formation rate in relation to progesterone levels in IVF/ICSI cycles, showing that increasing progesterone is associated with lower rates of top quality blastocyst. Hence, the advantages of prolonging COS to maximize the number of collected oocytes might eventually be hindered by a decrease in top quality blastocysts available for transfer, if increasing progesterone levels are observed. This observation extends the results of two recent studies focused on day-3 embryos and deserves further research.

Abstract
Final oocyte maturation using GnRH-agonist trigger in a GnRH-antagonist protocol is increasingly common, as ovarian hyperstimulation syndrome is almost completely avoided. However, this approach might lead to reduced pregnancy rates due to severe luteolysis. This proof of concept study evaluated the extend of luteolysis by measuring progesterone levels 48 hours after oocyte retrieval in 51 patients, who received GnRH-agonist trigger for final oocyte maturation in a GnRH-antagonist protocol due to the risk of ovarian hyperstimulation syndrome. It was shown, that luteolysis after GnRHa-trigger differs greatly among patients, with progesterone levels ranging from 13.0 ng/ml to ≥ 60.0 ng/ml, 48 hours after oocyte retrieval. Significant positive correlations could be demonstrated between progesterone levels and the number of ovarian stimulation and suppression days (p = 0.006 and p = 0.002 respectively), the total amount of medication used for ovarian suppression (p = 0.015), the level of progesterone on the day of final oocyte maturation (p = 0.008) and the number of retrieved oocytes (p = 0.019). Therefore it was concluded, that luteolysis after GnRH-agonist trigger is patient-specific and also luteal phase support requires individualization. Longer stimulation duration as well as a higher level of progesterone on the day of final oocyte maturation and more retrieved oocytes will result in higher levels of progesterone 48 hours after oocyte retrieval.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of gonadotropin-releasing hormone antagonist (GnRH-ant) protocol and gonadotropin-releasing hormone agonist (GnRH-a) long protocol in patients with normal ovarian reserve. METHODS We searched the PubMed (1992-2016), Cochrane Library (1999-2016), Web of Science (1950-2016), Chinese Biomedical Database (CBM, 1979-2016), and China National Knowledge Infrastructure (CNKI, 1994-2016). Any randomized controlled trials (RCTs) that compared GnRH-ant protocol and GnRH-a long protocol in patients with normal ovarian reserve were included, and data were extracted independently by two reviewers. The meta-analysis was performed by Revman 5.3 software. RESULTS Twenty-nine RCTs (6399 patients) were included in this meta-analysis. Stimulation days (mean difference (MD) [95% confidence interval (CI)] = -0.8 [-1.36, -0.23], P = 0.006), gonadotrophin (Gn) dosage (MD [95% CI] = -3.52 [-5.56, -1.48], P = 0.0007), estradiol (E2) level on the day of human chorionic gonadotrophin (HCG) administration (MD [95% CI] = -365.49 [-532.93, -198.05], P<0.0001), the number of oocytes retrieved (MD [95% CI] = -1.41 [-1.84, -0.99], P<0.00001), the embryos obtained (MD [95% CI] = -0.99 [-1.38, -0.59], P<0.00001), incidence of ovarian hyperstimulation syndrome (OHSS) (OR [95% CI] = 0.69 [0.57, 0.83], P<0.0001) were statistically significantly lower in GnRH-ant protocol than GnRH-a long protocol. However, the clinical pregnancy rate (OR [95% CI] = 0.90 [0.80, 1.01], P = 0.08), ongoing pregnancy rate (OR [95% CI] = 0.88 [0.77, 1.00], P = 0.05), live birth rate (OR [95% CI] = 0.95 [0.74, 1.09], P = 0.27), miscarriage rate (OR [95% CI] = 0.98 [0.69, 1.40], P = 0.93), and cycle cancellation rate (OR [95% CI] = 0.86 [0.52, 1.44], P = 0.57) showed no significant differences between the two groups. CONCLUSION GnRH-ant protocol substantially decreased the incidence of OHSS without influencing the pregnancy rate and live birth rate compared to GnRH-a long protocol among patients with normal ovarian reserve.

Abstract
Background Atosiban is administered to women undergoing in vitro fertilization-embryo transfer (IVF-ET) to improve pregnancy outcomes. However, the results of this treatment were controversial. We conducted this meta-analysis to investigate whether atosiban improves pregnancy outcomes in the women undergoing in vitro fertilization (IVF). Methods Databases of PubMed, EMBASE, Web of Science, China BioMedicine, and Google Scholar were systematically searched. Meta-analyses were performed to investigate whether atosiban improves pregnancy outcomes in the women undergoing IVF. Results Our results showed that atosiban was associated with higher implantation (OR = 1.63, 95% CI: 1.17–2.27; P = 0.004) and clinical pregnancy (OR = 1.84, 95% CI: 1.31–2.57; P < 0.001) rates. However, atosiban showed no significant association with the miscarriage, live birth, multiple pregnancy or ectopic pregnancy rates. When a further subgroup analysis was performed in the women undergoing repeated implantation failure (RIF), implantation (OR = 1.93, 95% CI: 1.45–2.57; P < 0.001), clinical pregnancy (OR = 2.48, 95% CI: 1.70–3.64; P <0.001) and the live birth (OR = 2.89, 95% CI: 1.78–4.67; P < 0.001) rates were significantly higher in the case group. Nevertheless, no significant difference was detected in the miscarriage and multiple pregnancy rates between the case and control groups. Conclusion Atosiban may be more appropriate for women undergoing RIF and play only a limited role in improving pregnancy outcomes in the general population of women undergoing IVF. These conclusions should be verified in large and well-designed studies.

Abstract
Over the past few years, the use of Gonadotropin-releasing-hormone (GnRH)-agonist for final oocyte maturation in GnRH-antagonist-protocols in stimulated IVF/ICSI cycles has gained worldwide acceptance, as this approach reduces significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Final oocyte maturation with GnRH-agonist leads to sever luteolysis, which cannot be counterbalanced using standard luteal phase support with purely progesterone (P4) application and therefore administration of hCG or high doses of P4 is considered to be essential to prevent/counteract luteolysis. However, lately publications indicate, that luteolysis is not always complete after GnRH-agonist for trigger. This case-series evaluates the degree of luteolysis in high-responder-patients, who received GnRH-agonist for final oocyte maturation. Assessment of estradiol (E2)- and P4-levels 48 h after oocyte-pick-up (OPU) procedure demonstrate clearly, that luteolysis after GnRH-agonist trigger is individual-specific, even in high-responder patients with the same number of oocytes. Hence, individualization of luteal phase support with the focus on avoiding unnecessary administration of hCG, bearing the risk for development of OHSS, a new concept of luteal coasting needs to be developed, based on severity of luteolysis following luteal coasting.

Abstract
The third-generation aromatase inhibitors (AIs), anastrozole, letrozole and exemestane, are highly effective for the treatment of estrogen receptor-positive breast cancer in postmenopausal women. AIs inhibit the aromatase (CYP19A1)-mediated production of estrogens. Most patients taking AIs achieve undetectable blood estrogen concentrations resulting in drug efficacy with tolerable side effects. However, some patients have suboptimal outcomes, which may be due, in part, to inherited germline genetic variants. This review summarizes published germline genetic associations with AI treatment outcomes including systemic AI concentrations, estrogenic response to AIs, AI treatment efficacy and AI treatment toxicities. Significant associations are highlighted with commentary about prioritization for future validation to identify pharmacogenetic predictors of AI treatment outcomes that can be used to inform personalized treatment decisions in patients with estrogen receptor-positive breast cancer.

Abstract
No significant differences in outcomes have been found between protocols of endometrial preparation for frozen embryo transfer (FET), though gonadotropin releasing hormone (GnRH) antagonists may have detrimental effects on the endometrium. We conducted a retrospective cohort noninferiority study at a single academic center of women receiving multiple doses of mid-cycle GnRH antagonist (GAnt) to those receiving GnRH agonist (GAg) to determine if there are detrimental effects of GnRH antagonists. 1047 FET cycles were identified, detailed data was available in 840 cycles: 610 GAg and 230 GAnt cycles. Patients undergoing GAnt cycles were older (40 ± 6.6 versus 37 ± 5.1 years, p < 0.0001), more often used donor oocyte (36% versus 18.6%, p < 0.0001), and more often exhibited diminished ovarian reserve (49.1% versus 36.2%, p = 0.0009). Clinical pregnancy rates (CPRs) per transfer and implantation rates (IRs) were similar for GAnt and GAg cycles. There was a trend for higher pregnancy and IRs with GAg cycles in younger women (CPR 38.8% versus 26.7%, p = 0.16; IR 36% versus 23.3%, p = 0.07). Stratifying by diagnosis, CPR and IR were similar in GAnt and GAg cycles. A GAnt protocol of endometrial preparation for FET is not inferior to a GAg protocol regardless of patient age, use of donor oocyte, or infertility diagnosis.
