There are two reasons supporting a “Freeze-only” strategy. One is that frozen-thawed embryos are transferred to a more physiologically receptive endometrium. While fresh embryos are transferred to a badly affected one because of controlled-ovarian stimulations, which cause the discordant development of the endometrium, when thawed-frozen embryos are transferred in a subsequent cycle the endometrium is not affected by high estrogen levels. The other reason is the big difference in cryopreservation and stimulation techniques. Methods: We investigated the annual ART reports in Japan from 1992 to 2018, and our clinical outcomes of frozen-thawed embryo transfers and fresh embryo transfers from 2015 to 2019. This enabled the assessment of the survival rate of frozen blastocyst by Cryotop safety kit after thawing in four different clinics. We compared the outcomes of frozen embryo transfer (FroET) to fresh embryo transfer. Results: The proportion of birth in Japan in the study interval found that FroET was responsible for 86.7% of births, compared to 13.3% of births resulting from fresh embryo transfers after IVF or intracytoplasmic sperm injection (ICSI). Clinical outcome of FroET in our clinic was significantly higher than that of fresh embryo transfer regardless of maternal age and number of collected oocytes. Average survival rate of frozen blastocyst by Cryotop safety kit after thawing in four clinics was over 95%. Conclusions: We believe that “Freeze-only high-quality blastocysts” is superior to fresh embryo transfer in terms of clinical outcome, at least when compared to historical results.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78173657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although its essential clinical manifestation includes a plethora of symptoms and signs, which largely reflects the underlying hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology, PCOS may also be associated with many metabolic derangements. These metabolic derangements happen to overlap with many of the core constituents of the metabolic syndrome (MBS)—increased insulin resistance, central obesity, and dyslipidemia. The two disorders also display similarly increased risks for certain metabolic and vascular diseases, such as type 2 diabetes mellitus, hypertension, and cardiovascular diseases. Due to the many similarities between metabolic syndrome and PCOS, this review aims to examine the evidence concerning the overlapping features, the risks for comorbidities, possible shared mechanisms, and treatment strategies in patients with coexisting PCOS and MBS.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86309361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, morphological embryo assessment has a number of limitations, including the time required, lack of accuracy, and inconsistency. This study determined whether a machine learning-based model could predict blastocyst formation using day-3 embryo images. Methods:Day-3 embryo images from IVF/intracytoplasmic sperm injection (ICSI) cycles performed at My Duc Phu Nhuan Hospital between August 2018 and June 2019 were retrospectively analyzed to inform model development. Day-3 embryo images derived from two-pronuclear (2PN) zygotes with known blastocyst formation data were extracted from the CCM-iBIS time-lapse incubator (Astec, Japan) at 67 hours post ICSI, and labeled as blastocyst/non-blastocyst based on results at 116 hours post ICSI. Images were used as the input dataset to train (85%) and validate (15%) the convolutional neural network (CNN) model, then model accuracy was determined using the training and validation dataset. The performance of 13 experienced embryologists for predicting blastocyst formation based on 100 day-3 embryo images was also evaluated. Results:A total of 1,135 images were allocated into training ([Formula: see text] = 967) and validation ([Formula: see text] = 168) sets, with an even distribution for blastocyst formation outcome. The accuracy of the final model for blastocyst formation was 97.72% in the training dataset and 76.19% in the validation dataset. The final model predicted blastocyst formation from day-3 embryo images in the validation dataset with an area under the curve of 0.75 (95% confidence interval [CI] 0.69–0.81). Embryologists predicted blastocyst formation with the accuracy of 70.07% (95% CI 68.12%–72.03%), sensitivity of 87.04% (95% CI 82.56%–91.52%), and specificity of 30.93% (95% CI 29.35%–32.51%). Conclusions:The CNN-based machine learning model using day-3 embryo images predicted blastocyst formation more accurately than experienced embryologists. The CNN-based model is a potential tool to predict additional IVF outcomes.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78464989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aging and loss of ovarian or adrenal function, among others, can lower testosterone levels in women. However, international guidelines currently do not routinely recommend androgen replacement therapy due to lack of long-term safety data. Evidence on its benefits and risks still remains uncertain. Objectives: The aim of this literature review is to present current studies and guidelines that examined the effects of testosterone therapy for postmenopausal women, including its role on cognition and mood; breast and endometrial cancer risks; musculoskeletal, cardiovascular, and genitourinary health; and sexual function. Methodology: A review of literature was done using PubMed, EMBASE, Science Direct, OVID, and Google scholar, with the following key words: androgen, testosterone, menopause, and hypoactive sexual desire dysfunction. We identified reviews, clinical trials, and guidelines. The population was limited to postmenopausal women. Results: There is no evidence from current published literature to support the use of testosterone therapy for female well-being, mood and cognition, bone and cardiovascular health. Intravaginal testosterone appears to be a promising alternative for the treatment of genitourinary symptoms of menopause (GSM) but efficacy and safety are yet to be confirmed. Well-designed, randomized, and placebo-controlled trials are needed to establish long-term safety, efficacy, and appropriate dosing and route of testosterone therapy in postmenopausal women. The only evidence-based indication for testosterone therapy in women is for the treatment of postmenopausal hypoactive sexual desire disorder (HSDD). Should a trial of testosterone therapy be given for HSDD, the transdermal route is the preferred method of delivery. Baseline total testosterone concentration should be determined before starting treatment, and repeated after 3–6 months. Serum testosterone levels should be monitored at regular intervals to avoid supraphysiologic dosing. Conclusion: Currently, there is no robust evidence to support the use of exogenous testosterone to improve female well-being, musculoskeletal health, mood and cognition, as well as bone and cardiovascular health among postmenopausal women. The only evidence-based indication for testosterone therapy in women is the treatment of postmenopausal hypoactive sexual desire disorder, but only after all other causes of sexual dysfunction have been ruled out. To date, testosterone therapy has no US Food and Drug Administration (US FDA) approval due to the lack of long-term efficacy and safety data.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75540141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study Design: Multicentre randomized controlled trial recruiting 57 women who were treated with ovarian stimulation using either 150 or 300 IU Menopur per day. Both groups received GnRH antagonist from day 5 of ovarian stimulation and final oocyte maturation was induced using a leuprolide GnRH (gonadotropin releasing hormone) agonist trigger when three or more follicles reached 17 mm diameter. Oocyte collection was scheduled 36–38 hours post trigger. In vitro fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) were performed according to individual unit protocol and embryos were cultured to blastocyst stage. A trophectoderm biopsy was performed on day 5 of embryo culture and used for preimplantation genetic testing for aneuploidy. Euploid embryos were transferred in subsequent frozen embryo transfer cycles with appropriate endometrial preparation. Results: The number of oocytes obtained from women randomized to 150 IU Menopur was between 3 and 17 (mean = 9), whereas the number of oocytes obtained from women randomized to 300 IU Menopur was between 3 and 24 (mean = 11). There was a positive linear relationship between serum AMH concentration and oocyte yield in both the 150 and 300 IU Menopur groups ([Formula: see text] = 0.3359, [Formula: see text] = 0.1129 and [Formula: see text] = 0.3741, [Formula: see text] = 0.1399).

Conclusion: The higher dose ovarian stimulation protocol did not significantly increase the number of oocytes retrieved, nor did the higher dose protocol reduce the proportion of euploid embryos created. This study does not support the hypothesis that use of higher doses of gonadotropin for ovarian stimulation results in a reduction in the proportion of euploid embryos obtained after IVF.","PeriodicalId":34382,"journal":{"name":"Fertility Reproduction","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88514633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
