Impact of updated international diagnostic criteria for the diagnosis of polycystic ovary syndrome.

Objective: To study whether application of the new 2018 guidelines for the diagnosis of polycystic ovary syndrome (PCOS) would decrease the diagnosis of PCOS. Second, to compare the metabolic profiles of women included and excluded in this new definition. Design: Retrospective cross-sectional chart review. Setting: University-affiliated hospital system. Patients: Women, ages 12-50, with the International Classification of Diseases code "Polycystic Ovary Syndrome" in 2017. Interventions: Application of the new 2018 guidelines for the diagnosis of PCOS. Main Outcome Measures: The primary outcome was the retention of PCOS diagnosis after applying the new 2018 guidelines. Secondary outcomes included the comparison of metabolic risk factors. Analysis was performed using chi-square tests for categorical variables and unpaired t tests for continuous variables, with a P value of <.05 determined to be significant. Results: Of 258 women with PCOS based on Rotterdam criteria, only 195 (76%) met the criteria based on the new 2018 guidelines. Those women who only met Rotterdam criteria (n = 63) had significantly lower body mass index (32.7 vs. 35.8), lower total cholesterol levels (151 vs. 176 mg/dL), lower triglyceride levels (96 vs. 124 mg/dL), lower total (33.2 vs. 52.3 ng/dL) and free testosterone levels (4.7 vs. 8.3), lower antimüllerian hormone levels (3.1 vs. 7.7 ng/mL), and were more likely to be multiparous (50% vs. 29%) than women who met 2018 criteria. Conclusions: Increasing the minimum antral follicle count to ≥20 antral follicles significantly decreases the number of women with the diagnosis of PCOS. Furthermore, the women that meet the new criteria have more health risks for metabolic syndrome than those who only meet the Rotterdam criteria.

High-sensitivity C-reactive protein levels and pregnancy outcomes in women with unexplained infertility after ovarian stimulation with intrauterine insemination in a multicenter trial.

Objective: To determine if chronic inflammation, assessed by basal high-sensitivity C-reactive protein (hs-CRP) levels, is associated with pregnancy outcomes in women with unexplained infertility undergoing ovarian stimulation with intrauterine insemination. Design: Prospective cohort analysis of the Reproductive Medicine Network's Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) randomized controlled trial. Setting: Multicenter university-based randomized controlled trial. Patients: A total of 781 couples with unexplained infertility. Interventions: Secondary analysis. Main Outcome Measures: Adjusted risk ratios of live birth, clinical pregnancy, and pregnancy loss rates by hs-CRP levels. Results: Associations between hs-CRP levels and clinical pregnancy rates were not observed after adjustment for baseline body mass index. There were fewer live births among women with higher hs-CRP levels, although confidence intervals crossed 1.0. The risk of pregnancy loss was greater in women with increased hs-CRP levels (1-3 mg/L: risk ratio [RR], 1.67; 95% confidence interval [CI], 1.00-2.79; >3-10 mg/L: RR, 1.84; 95% CI, 1.06-3.20; and >10 mg/L: RR, 2.14; 95% CI, 1.05-4.36 compared to women with hs-CRP <1 mg/L). Conclusions: This investigation suggests that chronic inflammation may increase the risk of pregnancy loss but not impact the clinical pregnancy rate in women with unexplained infertility undergoing ovarian stimulation with intrauterine insemination. Associations between inflammation and pregnancy outcomes in women with infertility merit further investigation. Clinical Trial Registration Number: clinicaltrials.gov NCT01044862.

Common practices among consistently high-performing in vitro fertilization programs in the United States: 10-year update.

OBJECTIVE: To evaluate similarities and differences in clinical and laboratory practices among high-performing fertility clinics. DESIGN: Cross-sectional questionnaire study of selected programs. SETTING: Academic and private fertility practices performing in vitro fertilization (IVF). PATIENT(S): Not applicable. INTERVENTION(S): A comprehensive survey was conducted of 13 IVF programs performing at least 100 cycles a year and having high cumulative singleton delivery rates for 2 years. MAIN OUTCOME MEASURE(S): Clinical and laboratory IVF practices. RESULT(S): Although many areas of clinical practice varied among top programs, some commonalities were observed. All programs used a combination of follicle-stimulating hormone and luteinizing hormone for IVF stimulation, intramuscular progesterone in frozen embryo transfer cycles, ultrasound-guided embryo transfers, and a required semen analysis before starting the IVF cycle. Common laboratory practices included vitrification of embryos at the blastocyst stage, air quality control with positive air pressure and high-efficiency particulate air filtration, use of incubator gas filters, working on heated microscope stages, and incubating embryos in a low-oxygen environment, most often in benchtop incubators. CONCLUSION(S): Some areas of consistency in clinical and laboratory practices were noted among high-performing IVF programs that are likely contributing to their success. High-performing programs focused on singleton deliveries. As the field of IVF is rapidly evolving, it is imperative that we share best practices in an effort to improve outcomes from all clinics for the good of our patients.

The relationship of plasma antioxidant levels to semen parameters: the Males, Antioxidants, and Infertility (MOXI) randomized clinical trial.

PURPOSE: The understanding of the role of plasma antioxidant levels in male fertility in the USA is limited. In a secondary analysis of the Males, Antioxidants, and Infertility (MOXI) randomized clinical trial, we sought to determine whether serum levels of vitamin E (α-tocopherol), zinc, and selenium were correlated with semen parameters and couple fertility outcomes. METHODS: This study is a secondary analysis of the MOXI clinical trial. The primary endpoints in this secondary analysis include semen parameters, and DNA fragmentation and clinical outcomes including pregnancy and live birth. Analyses were completed using Wilcoxon's rank-sum test and linear regression models. RESULTS: At baseline, the analysis included plasma labs for vitamin E (n = 131), selenium (n = 124), and zinc (n = 128). All baseline plasma values were in the normal ranges. There was no association between selenium, zinc, or vitamin E levels and semen parameters or DNA fragmentation. Baseline antioxidant levels in the male partners did not predict pregnancy or live birth among all couples. Among those randomized to placebo, baseline male antioxidant levels did not differ between those couples with live birth and those that did not conceive or have a live birth. CONCLUSIONS: Among men attending fertility centers in the USA, who have sufficient plasma antioxidant levels of zinc, selenium, or vitamin E, no association was observed between vitamins and semen parameters or clinical outcomes in couples with male infertility. Higher levels of antioxidants among men with circulating antioxidants in the normal range do not appear to confer benefit on semen parameters or male fertility.

Interactive Learning Modules With Visual Feedback Improve Resident Learning in Colposcopy.

OBJECTIVE: The Accreditation Council for Graduate Medical Education and the Council on Resident Education in Obstetrics and Gynecology have milestones and/or competencies relating to colposcopy; however, the optimal way to reach these objectives is not proscribed and left to individual programs. Here, we aim to assess resident skill, confidence levels, perceived level of knowledge, and satisfaction with colposcopic training before and after implementation of a new interactive learning module with visual feedback. MATERIALS AND METHODS: A new online educational intervention was developed by the author (E.L.N.) based on adult learning theory and introduced into our obstetrics and gynecology resident colposcopy curriculum in July 2014. We assessed performance on an objective competency examination administered at baseline and repeated after 6 months of our 24 residents.In addition, we assessed resident confidence levels, perceived level of knowledge, and satisfaction with training before and 6 months after intervention. RESULTS: Scores on a national online examination improved after the intervention (p = .014). Significant improvements on the examination were seen in the sections of medical knowledge (p = .031) and management (p = .011). Residents' perceived knowledge increased significantly after the intervention (p = .030). CONCLUSIONS: Learning outcomes improved after introduction of a novel teaching intervention.

Inhibition of Hyaluronic Acid Synthesis Decreases Endometrial Cell Attachment, Migration, and Invasion.

To characterize the effects of 4-methylumbelliferone (4-MU) on expression of the hyaluronic acid (HA) system and on attachment, migration, and invasion of endometrial epithelial (EECs) and stroma cells (ESCs) to peritoneal mesothelial cells (PMCs), this in vitro study was performed in an Academic Center. De-identified endometrial tissue samples used were from reproductive-aged women. EECs and ESCs isolated from menstrual endometrial biopsies were treated with 4-MU or vehicle. Real-time polymerase chain reaction and western blot were used to assess expression of HA synthases (HAS), hyaluronidase, and standard CD44. Established in vitro assays were used to assess attachment, migration, and invasion with and without treatment with 4-MU. Chi square and Student's t-test were used to analyze the results as appropriate. The addition of 4-MU decreased mRNA and protein expression of HAS 2, HAS 3, and CD44 in EECs and ESCs compared to control. Treatment with 4-MU also decreased attachment, migration, and invasion of EECs and ESCs to PMCs compared to control. 4-MU decreases endometrial cell adhesion, migration, and invasion to PMCs. This effect appears to be mediated by a decrease in HAS 2, HAS 3, and CD44. 4-MU is a potential treatment for endometriosis. Future in vivo studies are needed to evaluate 4-MU as a therapeutic agent for endometriosis.

CD44 variant 6 is involved in the attachment and invasion of endometrial cells to peritoneum.

OBJECTIVE: To study the effects of CD44 standard (CD44s), CD44v3, and CD44v6 overexpression (OE) on immortalized human endometrial epithelial (iEECs) and stroma cells (human endometrial stromal cells [hESCs]) using in vitro assays and a nude mouse xenograft model. Menstrual endometrial cells from women with endometriosis have increased adhesion and also express higher levels of CD44 variant 6 (v6), but not v3, compared to menstrual endometrial cells from women without endometriosis. DESIGN: In vitro studies and in vivo xenograft model. SETTING: Academic center. PATIENTS(S): Deidentified immortalized endometrial epithelial tissue samples of a reproductive-age woman. INTERVENTION(S): Overexpression of CD44s, CD44v3, and CD44v6 was carried out using lipofectamine, and their expression was verified with mRNA and protein in iEEC and hESCs. The OE cells were used in in vitro studies and an in vivo xenograft model compared to plasmid control. MAIN OUTCOME MEASURE(S): The effect of CD44s, CD44v3, and CD44v6 OE on attachment and invasion assays and a xenograft model with immortalized human stromal and epithelial cells. RESULT(S): Expression of mRNA and protein confirmed appropriate OE of CD44s, CD44v3, and CD44v6 in the different cell types. CD44v6 OE increased attachment of hESCs compared with controls. CD44v6 OE did not change the attachment of iEECs. There was no difference in attachment in iEECs or hESCs with OE of CD44s or CD44v3. CONCLUSION(S): Overexpression of CD44v6 increases attachment of hESCs to peritoneal mesothelial cells in an in vitro assay and an in vivo xenograft model. Menstrual endometrial cell type and CD44 variants play a complex role in the development of the early endometriotic lesion.

Does assisted hatching affect live birth in fresh, first cycle in vitro fertilization in good and poor prognosis patients?

PURPOSE: To assess the effect of assisted hatching (AH) on live birth rate (LBR) in first cycle, fresh in vitro fertilization (IVF) in good and poor prognosis patients. METHODS: Retrospective cohort using cycles reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System. Live birth rate was compared in women who underwent first cycle, autologous, fresh IVF cycles with (n = 48,858) and without (n = 103,413) AH from 2007 to 2015. RESULTS: The propensity-weighted LBR was 39.2% with AH versus 43.9% without AH in all patients. The rate difference (RD) with AH was - 4.7% ([CI - 0.053, - 0.040], P < 0.001) with the calculated number needed to harm being 22. AH affected live birth in both good prognosis and poor prognosis patients. The propensity-weighted monozygotic twinning (MZT) rate was 2.3% in patients treated with AH as compared to 1.2% patients that did not receive AH. The RD with AH on MZT in fresh, first IVF cycles was 1.1% ([0.008, 0.014], P < 0.001). CONCLUSION: AH may affect LBR across all patients and in poor prognosis patients in fresh IVF cycles. Caution should be exercised when applying this technology. More prospective research is needed.

Prewash total motile count is a poor predictor of live birth in intrauterine insemination cycles.

OBJECTIVE: To determine whether there is a relationship between prewash total motile count and live births in couples undergoing IUI. DESIGN: Retrospective review in a single academic center. SETTING: Not applicable. PATIENT(S): Couples with infertility undergoing ovulation induction with IUI between 2010 and 2014. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Live births. RESULT(S): Our cohort included 310 women who underwent 655 IUI cycles with a cumulative live birth rate (LBR) per couple of 20% and an LBR per cycle of 10%. A analysis yielded no correlation between prewash total motile count (TMC) and live births. No live births occurred with TMC <2 million sperms. Age had a significant negative relationship to LBR. A receiver operating characteristic analysis comparing age and live births indicated a significant decline in live births for women >37 years (90% sensitivity, 70% specificity). The LBR per couple was decreased to 7% in women >37 years compared with 25% in women <37 years. CONCLUSION(S): Prewash TMC is a poor predictor of live birth. There were no live births with prewash TMC <2 million sperms. The LBR for women >37 years with IUI was significantly lower than women <37 years.

The Hyaluronic Acid System is Intact in Menstrual Endometrial Cells in Women With and Without Endometriosis.

OBJECTIVE: To characterize the production and degradation of hyaluronic acid (HA) in menstrual endometrial epithelial cells (EECs) and endometrial stromal cells (ESCs) in women with and without endometriosis. To identify the presence of CD44, the primary receptor of HA, in menstrual EECs and ESCs in women with and without endometriosis. DESIGN: In vitro study. SETTING: Academic center. PATIENT(S): Deidentified patient samples from women with and without endometriosis. INTERVENTIONS: EECs and ESCs were isolated from menstrual endometrial biopsies performed on women with (N = 9) and without (N = 11) endometriosis confirmed by laparoscopy. MAIN OUTCOME MEASURE: Real-time polymerase chain reaction, Western blot, and immunohistochemistry were used to assess hyaluronic acid synthase (HAS) isoforms 1, 2, and 3; hyaluronidase (HYAL) isoforms 1 and 2; and standard CD44. Student t test was used to analyze the results. RESULTS: There was no significant difference in messenger RNA (mRNA) or protein expression of HAS2, HAS3, HYAL1, or HYAL2 in EECs or ESCs from women with or without endometriosis. HAS1 mRNA was variably detected, whereas HAS1 protein was similarly expressed in EECs and ESCs from women with and without endometriosis. Standard CD44 was expressed in both cell types, and expression did not differ in cells from women with or without endometriosis. CONCLUSIONS: The HA system is expressed in eutopic menstrual ESCs and EECs from women with and without endometriosis. There are no differences in expression in HA production or degradation enzymes in EECs or ESCs from women with and without endometriosis. Standard CD44 expression does not differ in eutopic menstrual endometrial cells from women with and without endometriosis.

Mediator Kinase Disruption in MED12-Mutant Uterine Fibroids From Hispanic Women of South Texas.

Context: Mutations in the gene encoding Mediator complex subunit MED12 are dominant drivers of uterine fibroids (UFs) in women of diverse racial and ethnic origins. Previously, we showed that UF-linked mutations in MED12 disrupt its ability to activate cyclin C-CDK8/19 in Mediator. However, validation of Mediator kinase disruption in the clinically relevant setting of MED12-mutant UFs is currently lacking. Objective: The objective of this study was twofold. First, to extend the ethnic distribution profile of MED12 mutations by establishing their frequency in UFs from Hispanic women of South Texas. Second, to examine the impact of MED12 mutations on Mediator kinase activity in patient-derived UFs. Methods: We screened 219 UFs from 76 women, including 170 tumors from 57 Hispanic patients, for MED12 exon 2 mutations, and further examined CDK8/19 activity in Mediator complexes immunoprecipitated from MED12 mutation-negative and MED12 mutation-positive UFs. Results: MED12 exon 2 mutations in UFs from Hispanic women are somatic in nature, predominantly monoallelic, and occur at high frequency (54.1%). We identified a minimal cyclin C-CDK8 activation domain on MED12 spanning amino acids 15 through 80 that includes all recorded UF-linked mutations in MED12, suggesting that disruption of Mediator kinase activity is a principal biochemical defect arising from these pathogenic alterations. Analysis of Mediator complexes recovered from patient UFs confirmed this, revealing that Mediator kinase activity is selectively impaired in MED12-mutant UFs. Conclusions: MED12 mutations are important drivers of UF formation in Hispanic women of South Texas. MED12 mutations disrupt Mediator kinase activity, implicating altered CDK8/19 function in UF pathogenesis.

Oncogenic exon 2 mutations in Mediator subunit MED12 disrupt allosteric activation of cyclin C-CDK8/19.

Somatic mutations in exon 2 of the RNA polymerase II transcriptional Mediator subunit MED12 occur at high frequency in uterine fibroids (UFs) and breast fibroepithelial tumors as well as recurrently, albeit less frequently, in malignant uterine leimyosarcomas, chronic lymphocytic leukemias, and colorectal cancers. Previously, we reported that UF-linked mutations in MED12 disrupt its ability to activate cyclin C (CycC)-dependent kinase 8 (CDK8) in Mediator, implicating impaired Mediator-associated CDK8 activity in the molecular pathogenesis of these clinically significant lesions. Notably, the CDK8 paralog CDK19 is also expressed in myometrium, and both CDK8 and CDK19 assemble into Mediator in a mutually exclusive manner, suggesting that CDK19 activity may also be germane to the pathogenesis of MED12 mutation-induced UFs. However, whether and how UF-linked mutations in MED12 affect CDK19 activation is unknown. Herein, we show that MED12 allosterically activates CDK19 and that UF-linked exon 2 mutations in MED12 disrupt its CDK19 stimulatory activity. Furthermore, we find that within the Mediator kinase module, MED13 directly binds to the MED12 C terminus, thereby suppressing an apparent UF mutation-induced conformational change in MED12 that otherwise disrupts its association with CycC-CDK8/19. Thus, in the presence of MED13, mutant MED12 can bind, but cannot activate, CycC-CDK8/19. These findings indicate that MED12 binding is necessary but not sufficient for CycC-CDK8/19 activation and reveal an additional step in the MED12-dependent activation process, one critically dependent on MED12 residues altered by UF-linked exon 2 mutations. These findings confirm that UF-linked mutations in MED12 disrupt composite Mediator-associated kinase activity and identify CDK8/19 as prospective therapeutic targets in UFs.

Assisted hatching and live births in first-cycle frozen embryo transfers.

OBJECTIVE: To assess the effect of assisted hatching (AH) on live-birth rates in a retrospective cohort of patients undergoing first-cycle, autologous frozen embryo transfer (FET). DESIGN: Longitudinal cohort using cycles reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System between 2004 and 2013. SETTING: Not applicable. PATIENT(S): Women who underwent first-cycle, autologous FET with (n = 70,738) and without (n = 80,795) AH reported from 2004 to 2013. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Live births. RESULT(S): Propensity matching was used to account for confounding covariates, and a logistic regression model was constructed to identify the predictors of live-birth rates in relationship to AH. In all first-cycle FETs, there was a slight but statistically significant decrease in the live-birth rate with AH compared with no AH (34.2% vs. 35.4%). In older patients and in the years 2012-2013 AH was associated with decreased live births. Live-birth rates and the number of AH cycles performed before FET vary by the geographic location of clinics. CONCLUSION(S): Assisted hatching slightly decreases the live-birth rate in first-cycle, autologous FET. Its use should be carefully considered, especially in patients 38 years old and older. Prospective, clinical studies are needed to improve our knowledge of the impact of AH.

Successful pregnancy following myomectomy for uterine smooth muscle tumor of uncertain malignant potential: A case report and review of the literature.

•STUMPs are rare smooth muscle tumors with an overall favorable prognosis.•Pregnancy is possible after diagnosis of STUMP treated with myomectomy•Management of patients desiring fertility with STUMPs requires a multidisciplinary approach.

Fertility Preservation Counseling for Pediatric and Adolescent Cancer Patients.

PURPOSE: Fertility preservation for children and young adults with cancer is an important part of comprehensive patient care. In 2013, the American Society of Clinical Oncology (ASCO) released updated clinical practice guidelines addressing fertility preservation. This study aimed to evaluate if pediatric oncologists were performing fertility preservation counseling, if the new guidelines were being adopted, and how reproductive endocrinologists can educate this patient population and their providers. METHODS: A cross-sectional study was performed from May 26, 2014, to August 26, 2014. An online survey addressing fertility preservation practice patterns was created and provided to the members of the Children's Oncology Group (COG). RESULTS: Thirty-five percent of the 234 respondents reported reading the new 2013 ASCO guidelines. Ninety-five percent of providers reported mentioning fertility preservation options prior to treatment, most commonly including referral to a reproductive endocrinologist (28%), and sperm banking (57%). The most commonly reported barrier to fertility preservation counseling was the cost of treatment. CONCLUSION: Fertility preservation counseling is being performed by pediatric oncology providers. Familiarity of the ASCO guidelines is limited, revealing that the established methods for fertility preservation in women--embryo and oocyte cryopreservation--may be offered less than experimental methods in this younger patient population. Such differences in apparent practice patterns highlight the need for more education for providers.

Impaired Development of Early Endometriotic Lesions in CD44 Knockout Mice.

Previous studies have shown endometrial cell (EC) CD44 and peritoneal mesothelial cell (PMC)-associated hyaluronan (hyaluronic acid [HA]) are involved in the attachment of endometrial stroma and epithelial cells to peritoneal mesothelium. Here we assess the CD44-HA interaction in the formation of the early endometriotic lesion using CD44(-/-) (knockout) mice. Using an established murine model and crossover technique, endometrial tissue from donor mice (wild type [WT] and CD44(-/-)) was used to induce endometriosis in recipient mice (WT and CD44(-/-)). Endometriotic lesions were visualized by fluorescent microscopy and confirmed by hematoxylin and eosin staining. Early endometriotic lesions were decreased when CD44(-/-) endometrium was placed in WT recipients and when WT endometrium was placed in CD44(-/-) recipients (P = .002). Early endometriotic lesions were also significantly decreased when both peritoneal and endometrial tissues lacked CD44 expression (P < .01). These studies demonstrate that both EC and PMC CD44 play a role in the development of early endometriotic lesion.

Fertility preservation in patients receiving chemotherapy or radiotherapy.

The preservation and restoration of fertility are key aspects for enhancing quality of life in cancer survivors. Cytotoxic agents and radiation can produce gonadal dysfunction in both men and women. Survival rates for cancers that occur before or during reproductive age have improved dramatically. Current fertility preservation options are available but limited in males and females. Referral to a reproductive endocrinologist around the time of diagnosis is important to optimize treatment options.
