RESUMO

Study question: Are the molecular signatures of cumulus cells (CCs) and follicular fluid (FF) of adolescents undergoing fertility preservation differ from that of reproductively adult oocyte donors? Summary answer: The microenvironment immediately surrounding the oocyte, including the CCs and FF, is altered in adolescents undergoing fertility preservation compared to oocyte donors. What is known already: Adolescents experience a period of subfecundity following menarche. Recent evidence suggests that this may be at least partially due to increased oocyte aneuploidy. Reproductive juvenescence in mammals is associated with suboptimal oocyte quality. Study design size duration: This was a prospective cohort study. Adolescents (10-19 years old, N=23) and oocyte donors (22-30 years old, N=31) undergoing ovarian stimulation and oocyte retrieval at the Northwestern Fertility and Reproductive Medicine Center between November 1, 2020 and May 1, 2023 were enrolled in this study. Participants/materials setting methods: Patient demographics, ovarian stimulation, and oocyte retrieval outcomes were collected for all participants. The transcriptome of CCs associated with mature oocytes was compared between adolescents (10-19 years old, n=19), and oocyte donors (22-30 years old, n=19) using bulk RNA-sequencing. FF cytokine profiles (10-19 years old, n=18 vs. 25-30 years old, n=16) were compared using cytokine arrays. Main results and the role of chance: RNA-seq analysis revealed 581 differentially expressed genes (DEGs) in cumulus cells of adolescents relative to oocyte donors, with 361 genes downregulated and 220 upregulated. Genes enriched in pathways involved in cell cycle and cell division (e.g., GO:1903047, p= 3.5 × 10-43; GO:0051983, p= 4.1 × 10-30; GO:0000281, p= 7.7 × 10-15; GO:0044839, p= 5.3 × 10-13) were significantly downregulated, while genes enriched in several pathways involved in cellular and vesicle organization (e.g., GO:0010256, p= 1.2 × 10-8; GO:0051129, p= 6.8 × 10-7; GO:0016050, p= 7.4 × 10-7; GO:0051640, p= 8.1 × 10-7) were upregulated in CCs of adolescents compared to oocyte donors. The levels of 9 cytokines were significantly increased in FF of adolescents compared to oocyte donors: IL-1 alpha (2-fold), IL-1 beta (1.7-fold), I-309 (2-fold), IL-15 (1.6-fold), TARC (1.9-fold), TPO (2.1-fold), IGFBP-4 (2-fold), IL-12-p40 (1.7-fold) and ENA-78 (1.4-fold). Interestingly, 7 of these cytokines have known pro-inflammatory roles. Importantly, neither the CC transcriptomes or FF cytokine profiles were different in adolescents with or without cancer. Large scale data: Original high-throughput sequencing data will be deposited in Gene Expression Omnibus (GEO) before publication, and the GEO accession number will be provided here. Limitations reasons for caution: This study aims to gain insights into the associated gamete quality by studying the immediate oocyte microenvironment. The direct study of oocytes is more challenging due to sample scarcity, as they are cryopreserved for future use, but will provide a more accurate assessment of oocyte reproductive potential. Wider implications of the findings: Understanding the underpinnings of altered immediate oocyte microenvironment of adolescent patients may provide insights into the reproductive potential of the associated gametes in the younger end of the age spectrum. This has implications for the fertility preservation cycles for very young patients. Study funding/competing interests: This project was supported by Friends of Prentice organization SP0061324 (M.M.L and E.B.), Gesualdo Family Foundation (Research Scholar: M.M.L.), and NIH/NICHD K12 HD050121 (E.B.). The authors have declared that no conflict of interest exists.

RESUMO

Importance: Fertility preservation (FP), including oocyte and embryo cryopreservation prior to gonadotoxic therapy, is an urgent and essential component of comprehensive cancer care. Geographic proximity to a center offering FP is a critical component of ensuring equitable access for people with cancer desiring future fertility. Objective: To characterize the distribution of centers offering FP services in the US, quantify the number of self-identified reproductive-age female individuals living outside of geographically accessible areas, and investigate the association between geographic access and state FP mandates. Design, Setting, and Participants: This cross-sectional analysis calculated 2-hour travel time isochrone maps for each center based on latitude and longitude coordinates. Population-based geospatial analysis in the US was used in this study. Fertility clinics identified through the 2018 Centers for Disease Control and Prevention Fertility Clinic Success Rates Report were defined as oncofertility centers by meeting 4 criteria: (1) offered oocyte and embryo cryopreservation, (2) performed at least 1 FP cycle in 2018, (3) served people without partners, and (4) had an accredited laboratory. County-level data were obtained from the 2020 US Census, with the primary at-risk population identified as reproductive-age female individuals aged 15 years to 44 years. The analysis was performed from 2021 to 2022. Exposures: Location outside of 2-hour travel time isochrone of an oncofertility center. Main Outcomes and Measures: Oncofertility centers were compared with centers not meeting criteria and were classified by US region, state FP mandate status, number of assisted reproductive technology cycles performed, and number of FP cycles performed. The number and percentage of at-risk patients, defined as those living outside of accessible service areas by state, were identified. Results: Among 456 Centers for Disease Control and Prevention-reporting fertility clinics, 86 (18.9%) did not meet the criteria as an oncofertility center. A total of 3.63 million (5.70%) reproductive-age female individuals lack geographic access to an oncofertility center. States with FP mandates have the highest rates of eligible female patients with geographic access (98.54%), while states without active or pending legislation have the lowest rates (79.57%). The greatest disparities in geographic access to care are most concentrated in the Mountain West and West North Central regions. Conclusions and Relevance: Patients face numerous barriers to comprehensive cancer care, including a lack of geographic access to centers capable of offering FP services. This cross-sectional study identified disparities in geographic access and potential opportunities for strategic expansion.

RESUMO

Purpose: Throughout COVID-19, our clinic remained operational for patients requiring urgent fertility preservation (FP). This study aimed to characterize changes to clinical protocols during the first wave of COVID-19 and compare outcomes to historical controls. Methods: We performed a retrospective cohort study at a university fertility center examining all patients who underwent medically indicated FP cycles during the American Society for Reproductive Medicine (ASRM) COVID-19 Task Force-recommended suspension of fertility treatment (March 17-May 11, 2020) and patients from the same time period in 2019. FP care was modified for safety during the first wave of COVID-19 with fewer monitoring visits and infection control measures. FP cycle characteristics and outcomes were compared across years. Results: The volume of cycles was nearly 30% higher in 2020 versus 2019 (27 vs. 19). Diagnoses, age, and anti-Mullerian hormone were similar between cohorts. More patients elected to pursue embryo cryopreservation over oocyte cryopreservation in 2020 versus 2019 (45.8% vs. 5.2%, p < 0.005). Patients managed during COVID-19 had fewer monitoring visits (5 ± 1 vs. 6 ± 1, p = 0.02), and 37.5% of cycles utilized a blind trigger injection. There was no difference in total days of ovarian stimulation (11 ± 1 vs. 11 ± 2, p > 0.05), but 2020 cycles utilized more gonadotropin (4770 ± 1480 vs. 3846 ± 1438, p = 0.04). There was no difference in total oocytes retrieved (19 ± 14 vs. 22 ± 12, p > 0.05) or mature oocytes vitrified (15 ± 12 vs. 17 ± 9, p > 0.05) per cycle. Conclusions: FP continued during COVID-19, and more cycles were completed in 2020 versus 2019. Despite minimized monitoring, outcomes were optimal and equivalent to historical controls, suggesting FP care can be adapted without compromising outcomes.

RESUMO

PURPOSE: Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium. METHODS: The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process. RESULTS: This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity. CONCLUSION: The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future.

RESUMO

PURPOSE: Improving access to care is an issue at the forefront of reproductive medicine. We sought to describe how one academic center, set in the background of a large and diverse metropolitan city, cares for patients with extremely limited access to reproductive specialists. METHODS: The NYU Reproductive Endocrinology and Infertility (REI) Fellowship program provides a "fellow-run clinic" within Manhattan's Bellevue Hospital Center, which is led by the REI fellows and supervised by the REI attendings of the NYU Langone Health system. A description of the history of the hospital as well as the logistics of the fertility clinic is provided as a logistical template for implementation. RESULTS: The fellow-run fertility clinic at Bellevue hospital is held on two half days per month seeing approximately 150 new patients per year. The fertility workup, counseling, surgery, as well as ovulation induction, and early pregnancy management are offered within the construct of the fellowship and residency at NYU. Barriers to care and ways to circumvent those barriers are discussed in detail. CONCLUSION: By utilizing the ambition and construct of the OB/GYN programs, we greatly improve care for an otherwise underserved patient population by offering an efficient and optimal infertility workup and treatment in a population that would otherwise be without care. We utilize the framework of graduate medical education to provide autonomy, experience, and mentorship to both residents and fellows in our programs in an effort to provide a solution to combating inequity in infertility care.

RESUMO

OBJECTIVE: To investigate the use of preimplantation genetic testing for aneuploidy (PGT-A) among patients pursuing embryo banking (EB) for medically indicated fertility preservation (FP). DESIGN: Retrospective cohort. SETTING: University-affiliated fertility center. PATIENTS: All patients who underwent in vitro fertilization with or without PGT-A for medically indicated FP between January 2014 and April 2018. INTERVENTIONS: None MAIN OUTCOME MEASURES: EB cycle characteristics, subsequent cycle pursuit/outcomes, and frozen embryo transfer (FET) outcomes. RESULTS: A total of 58 medical EB cycles were compared; 34 cycles used PGT-A. Of the EB patients with breast cancer, 67% used PGT-A; other indications were evenly divided between PGT-A (FP/PGT-A) and no PGT-A (FP). PGT-A use increased over the study period. Groups were similar in age, days of stimulation, and days from initial FP consultation to treatment initiation. Number of oocytes (14.5 [2-63] FP vs. 17.5 [1-64] FP/PGT-A), 2PN zygotes (7 [1-38] FP vs. 9 [0-36] FP/PGT-A), and blastocysts (5.5 [0-22] FP vs. 5 [0-18] FP/PGT-A) cryopreserved were similar between groups. Equal numbers cryopreserved both oocytes and embryos (5 vs. 3). Five FP/PGT-A patients underwent a second EB cycle. Among FP/PGT-A patients, an average of 6.7 ± 5 blastocysts underwent PGT-A, with 3.5 ± 3 (48.2%) euploid embryos cryopreserved for future FET compared to an average of 7.2 ± 7 untested embryos in the FP group. CONCLUSION: PGT-A in medical EB cycles increased over time and did not limit the use of other FP methods such as oocyte cryopreservation. In some cases, poor PGT-A results informed patients to pursue a second EB cycle. When counseling patients, the prognostic benefits of PGT-A must be weighed against the financial costs and potential for "terminal" fertility diagnosis.

RESUMO

STUDY QUESTION: What factors are associated with decision regret and anxiety following preimplantation genetic testing for aneuploidy (PGT-A)? SUMMARY ANSWER: The majority of patients viewed PGT-A favourably regardless of their outcome; although patients with negative outcomes expressed greater decision regret and anxiety. WHAT IS KNOWN ALREADY: PGT-A is increasingly utilized in in vitro fertilization (IVF) cycles to aid in embryo selection. Despite the increasing use of PGT-A technology, little is known about patients' experiences and the possible unintended consequences of decision regret and anxiety related to PGT-A outcome. STUDY DESIGN, SIZE, DURATION: Anonymous surveys were distributed to 395 patients who underwent their first cycle of autologous PGT-A between January 2014 and March 2015. PARTICIPANTS/MATERIALS, SETTING, METHODS: There were 69 respondents who underwent PGT-A at a university-affiliated fertility centre, completed the survey and met inclusion criteria. Respondents completed three validated questionnaires including the Brehaut Decision Regret (DR) Scale, short-form State-Trait Anxiety Inventory (STAI-6) and a health literacy scale. The surveys also assessed demographics, fertility history, IVF and frozen embryo transfer cycle data. MAIN RESULTS AND THE ROLE OF CHANCE: The majority of respondents were Caucasian, >35 years of age and educated beyond an undergraduate degree. The majority utilized PGT-A on their first IVF cycle, most commonly to 'maximize the efficiency of IVF' or reduce per-transfer miscarriage risk. The overall median DR score was low, but 39% of respondents expressed some degree of regret. Multiple regression confirmed a relationship between embryo ploidy and decision regret, with a lower number of euploid embryos associated with a greater degree of regret. Patients who conceived following euploid transfer reported less regret than those who miscarried or failed to conceive (P < 0.005). Decision regret was inversely associated with number of living children but not associated with age, education, race, insurance coverage, religion, marital status or indication for IVF/PGT-A. Anxiety was greater following a negative pregnancy test or miscarriage compared to successful conception (P < 0.0001). Anxiety was negatively associated with age, time since oocyte retrieval and number of living children, and a relationship was observed between anxiety and religious affiliation. Overall, decision regret was low, and 94% of all respondents reported satisfaction with their decision to pursue PGT-A; however, patients with a negative outcome were more likely to express decision regret and anxiety. LIMITATIONS, REASON FOR CAUTION: This survey was performed at a single centre with a relatively homogenous population, and the findings may not be generalizable. Reasons for caution include the possibility of response bias and unmeasured differences among those who did and did not respond to the survey, as well as the possibility of recall bias given the retrospective nature of the survey. Few studies have examined patient perceptions of PGT-A, and our findings should be interpreted with caution. WIDER IMPLICATIONS OF THE FINDINGS: Overall decision regret was low following PGT-A, and the vast majority deemed the information gained valuable for reproductive planning regardless of outcome. However, more than one-third of the respondents expressed some degree of regret. Respondents with no euploid embryos were more likely to express regret, and those with a negative outcome following euploid embryo transfer expressed both higher regret and anxiety. These data identify unanticipated consequences of PGT-A and suggest opportunities for additional counselling and support surrounding IVF with PGT-A.

RESUMO

The ovary contains oocytes within immature (primordial) follicles that are fixed in number at birth. Activation of follicles within this fixed pool causes an irreversible decline in reproductive capacity, known as the ovarian reserve, until menopause. Premenopausal women undergoing commonly used genotoxic (DNA-damaging) chemotherapy experience an accelerated loss of the ovarian reserve, leading to subfertility and infertility. Therefore, there is considerable interest but little effective progress in preserving ovarian function during chemotherapy. Here we show that blocking the kinase mammalian/mechanistic target of rapamycin (mTOR) with clinically available small-molecule inhibitors preserves ovarian function and fertility during chemotherapy. Using a clinically relevant mouse model of chemotherapy-induced gonadotoxicity by cyclophosphamide, and inhibition of mTOR complex 1 (mTORC1) with the clinically approved drug everolimus (RAD001) or inhibition of mTORC1/2 with the experimental drug INK128, we show that mTOR inhibition preserves the ovarian reserve, primordial follicle counts, serum anti-Mullerian hormone levels (a rigorous measure of the ovarian reserve), and fertility. Chemotherapy-treated animals had significantly fewer offspring compared with all other treatment groups, whereas cotreatment with mTOR inhibitors preserved normal fertility. Inhibition of mTORC1 or mTORC1/2 within ovaries was achieved during chemotherapy cotreatment, concomitant with preservation of primordial follicle counts. Importantly, our findings indicate that as little as a two- to fourfold reduction in mTOR activity preserves ovarian function and normal birth numbers. As everolimus is approved for tamoxifen-resistant or relapsing estrogen receptor-positive breast cancer, these findings represent a potentially effective and readily accessible pharmacologic approach to fertility preservation during conventional chemotherapy.

RESUMO

OBJECTIVE: To demonstrate that oocyte cryopreservation is a feasible reproductive option for patients with cancer of childbearing age who require gonadotoxic therapies. METHODS: This study is a university-based retrospective review of reproductive-aged cancer patient treatment cycles that included ovarian stimulation, transvaginal oocyte retrieval, oocyte cryopreservation, and, in some cases, subsequent oocyte thaw, in vitro fertilization, and embryo transfer. Outcome measures included ovarian stimulation response, number of oocytes retrieved, cryopreserved, and thawed, and pregnancy data. RESULTS: From 2005 to 2014, 176 reproductive-aged patients with cancer (median age 31 years, interquartile range 24-36) completed 182 oocyte cryopreservation cycles. Median time between consult request and oocyte retrieval was 12 days (interquartile range 10-14). Median peak stimulation estradiol was 1,446 pg/mL (interquartile range 730-2,687); 15 (interquartile range 9-23) oocytes were retrieved and 10 (interquartile range 5-18) metaphase II oocytes were cryopreserved per cycle. Ten patients (11 cycles) have returned to attempt pregnancy with their cryopreserved oocytes. Among thawed oocytes, the cryopreservation survival rate was 86% (confidence interval [CI] 78-94%). Nine of 11 thaw cycles resulted in embryos suitable for transfer. The embryo implantation rate was 27% (CI 8-46%) and the live birth rate was 44% (CI 12-77%) per embryo transfer. Chance for live birth with embryos created from cryopreserved oocytes was similar between the patients with cancer in this study and noncancer patients who underwent the same treatment at our center (44% [CI 12-77%] compared with 33% [CI 22-44%] per embryo transfer). CONCLUSION: Oocyte cryopreservation is now a feasible fertility preservation option for reproductive-aged patients with cancer who require gonadotoxic therapies.

RESUMO

OBJECTIVE: To determine whether an association exists between body mass index (BMI) and embryo ploidy in patients undergoing in vitro fertilization (IVF) with trophectoderm biopsy and 24-chromosome preimplantation genetic screening (PGS). DESIGN: Retrospective cohort study. SETTING: University-based fertility center. PATIENT(S): 279 women aged 20-45 years with documented height and weight from the day of oocyte retrieval who underwent 24-chromosome PGS between 2010 and 2013. INTERVENTION(S): None. PRIMARY OUTCOMES: number and percentage of euploid embryos. RESULT(S): Patients were grouped by World Health Organization (WHO) BMI class: underweight (<18.5, n = 11), normal weight (18.5-24.9, n = 196), overweight (25-29.9, n = 50), and obese (≥30, n = 22). Groups were similar by age (mean ± standard error of the mean: 37.5 ± 1.2 to 39.2 ± 0.9), ovarian reserve, and IVF cycle parameters. There was no difference in the number or percentage of euploid embryos by BMI category (<18.5: 27.6% ± 8.5; 18.5-24.9: 34.5% ± 2.2; 25-29.9: 32.1% ± 4.3; ≥30: 30.9% ± 7.3). Age was inversely related to euploidy, but adjusted multivariate regression models failed to demonstrate a statistically significant relationship between BMI and euploidy in underweight (adjusted odds ratio [AOR] 0.44; 95% confidence interval [CI], 0.09-2.10), overweight (AOR 0.90; 95% CI, 0.43-2.00), or obese (AOR 0.74; 95% CI, 0.25-2.20) patients compared with the normal-weight reference group. CONCLUSION(S): No statistically significant relationship was identified between BMI and euploidy in an otherwise homogenous cohort of patients undergoing IVF with PGS, suggesting that the negative impact of overweight and obesity on IVF and reproductive outcomes may not be related to aneuploidy.

RESUMO

OBJECTIVE: To determine if long-term cryopreservation of human oocytes affects oocyte developmental competence, blastocyst euploidy, or live-birth rates. DESIGN: Retrospective cohort study. SETTING: University-based fertility center. PATIENT(S): A total of 33 patients with cryopreserved oocytes underwent oocyte thaw, blastocyst culture, trophectoderm biopsy, and 24-chromosome preimplantation genetic screening (PGS) with array comparative genomic hybridization between December 2011 and July 2014; subjects were compared with 2:1 age-matched controls with fresh oocytes whose embryos underwent trophectoderm biopsy and PGS during the same period. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Rates of fertilization, blastulation, euploidy, implantation, and live birth. RESULT(S): Thirty-three patients (mean age 36.2 ± 3.8 y) thawed 475 oocytes that had been cryopreserved for a median of 3.5 years. Compared with 66 age-matched controls who underwent in vitro fertilization and PGS with fresh oocytes, embryos derived from cryopreserved oocytes demonstrated compromised blastocyst formation (54.5% vs. 66.2%) despite no impairment in fertilization (72.8% vs. 73.2%). Results showed no difference in the number of euploid blastocysts (1.7 ± 1.9 vs. 2 ± 2.5), percentage of euploid blastocysts (44.5% vs. 47.6%), rate of implantation (65% vs. 65%), or rate of live birth and ongoing pregnancy (62.5% vs. 55%) after 24-chromosome PGS with cryopreserved or fresh oocytes. CONCLUSION(S): Embryos derived from cryopreserved oocytes demonstrate impaired blastulation but equivalent rates of euploidy, implantation, and live birth compared with blastocysts derived from fresh oocytes, supporting the safety and efficacy of oocyte cryopreservation.

RESUMO

OBJECTIVE: To determine whether performing uterine artery embolization (UAE) immediately before laparoscopic myomectomy can facilitate a minimally invasive surgical approach for larger uterine fibroids. METHODS: In a retrospective case-control study, laparoscopic myomectomy with and without preoperative UAE was examined. Data were analyzed from 26 laparoscopic myomectomies performed by a single surgeon at Northwestern University Feinberg School of Medicine between 2004 and 2010. Controls were matched for age, calendar year, surgeon, and number of fibroids removed. Surgical outcomes included preoperative clinical uterine size, operative time, operative blood loss, and postoperative myoma specimen weight. Data were analyzed via 2-tailed Student t test. RESULTS: Twelve women underwent laparoscopic myomectomy within 169 ± 16minutes (mean ± SEM) of preoperative UAE. Fourteen control patients underwent laparoscopic myomectomy alone. The UAE group had a greater mean preoperative clinical uterine size (19.7 versus 12.4 weeks, P<0.001) and a greater mean myoma specimen weight measured postoperatively (595.3 versus 153.6 grams, P<0.05). There were no significant differences in operative time or blood loss, and there were no intra-operative complications. CONCLUSION: UAE performed immediately before laparoscopic myomectomy facilitated minimally invasive surgery for larger uteri and larger uterine myomas, with no differences in operative time or blood loss.

RESUMO

OBJECTIVE: To test the hypothesis that the high-risk patients at an inner city hospital with atypical glandular cells of undetermined significance (AGC) on their Pap smears have a higher rate of underlying significant pathology than that reported in published data. STUDY DESIGN: This was an Institutional Review Board-approved retrospective review of all AGC Pap smears performed at University Hospital, Newark, New Jersey, between January 1, 2001, and July 30, 2008. We defined significant pathology as cervical intraepithelial neoplasia 2 (CIN 2) or greater, endocervical adenocarcinoma in situ or greater, or simple hyperplasia or greater of the endometrium. RESULTS: Medical records of 126 patients were reviewed. Forty did not meet inclusion criteria; 86 patients were included in the analysis. Thirty of the 86 (34.9%) patients were found to have significant pathology. CONCLUSION: Patients with AGC Pap results at our inner city hospital have a high risk for underlying significant pathology.

RESUMO

BACKGROUND: Given the need for a 90-day post-Essure hysterosalpingogram (HSG) to confirm proper tubal placement and occlusion, we examined the impact of dedicating a staff nurse to schedule HSG appointments, call with appointment reminders and track HSG compliance for patients who had Essure. STUDY DESIGN: We performed a retrospective chart review for patients who underwent Essure sterilization between October 2003 and January 2009. We compared rates of HSG compliance and confirmed tubal occlusion for patients before February 2008 with rates after the protocol change occurred. RESULTS: Seventy-eight percent of preintervention patients were compliant with at least one HSG following Essure placement compared to 90.9% in the post-intervention group (p value=.033). Tubal occlusion was confirmed by postprocedure HSGs for 123/173 patients (71.1%) in the preintervention group and 48/55 patients (87.3%) in the postintervention group. Patients followed by our staff after our protocol change were more likely to undergo post-Essure compliance (Odds ratio= 2.7, confidence interval = 1.2-7.1, p=.01). CONCLUSION: Dedicating a staff nurse to track patients' HSG follow-up as a multicheck system resulted in an improvement in HSG compliance and rates of confirmed tubal placement and occlusion.
