An Analysis of Fertility Preservation Offerings for Transgender Youth on United States Pediatric Hospital Websites.

PURPOSE: To survey United States (U.S.) pediatric hospital websites for information about fertility preservation (FP) for transgender patients. Secondarily, to identify hospital characteristics associated with higher likelihood of publishing transgender-specific FP content on websites. METHODS: This cross-sectional study included all U.S. pediatric hospitals from Children's Hospital Association excluding specialty hospitals. From September-December 2023, 2 independent researchers surveyed websites for: geographic location, academic affiliation, religious affiliation, presence of general and transgender-specific FP information, and specialties of FP providers. Fisher's exact and Pearson's Chi-square tests were used. RESULTS: Of 177 websites surveyed, 41% (n = 73) published FP information, largely targeted to oncology patients (90%, n = 66). Only 8% (n = 15) of all websites mentioned FP for transgender youth. Based on website information, most fertility programs included a medical oncologist (80%, n = 53); fewer included a urologist (32%, n = 21), pediatric gynecologist (27%, n = 18) or reproductive endocrinologist (RE, 21%, n = 14). About half (n = 31) referred to affiliate REs. Presence of transgender-specific FP website content ranged from 0% to 5% in Southern divisions to 20% in New England (median = 10%). Secular (p < .001) and academic (p = .04) hospital websites were significantly more likely to include FP content. DISCUSSION: Our findings highlight a gap in access to FP information for transgender youth on U.S. pediatric hospital websites. Few websites identify FP teams that include an RE or pediatric gynecologist, who specialize in FP for patients with ovaries. Access to FP information is critical to transgender youth who may desire genetically related children later in life. Strategies to assure this information is widely available are needed.

A multi-center evaluation of a novel IVF cryostorage device in an active clinical setting.

The objective of this study was to evaluate the function, and usability of a novel automated software-guided cryostorage system in an active IVF laboratory setting. The investigational device (ID) was installed at 3 IVF laboratories (sites: α, ß, and γ). A total of 15 embryologists were trained to use the ID. Mock patient specimens containing mirrored live patient data were handled using the ID. Temperature readings were recorded every minute. Successful identification, storage, and retrieval of mock patient specimens by the ID were evaluated. To assess an LN2 pressure builder, the frequency of use and events of workflow interruption were logged. Student's t-test was used to determine statistical significance. The ID was in active use for 164 days total. During this time, 329 mock patient egg and embryo cohorts were handled by the ID. The mean ± SD temperatures during active use were: α, - 176.57 ± 1.83 °C; ß, - 178.21 ± 2.75 °C; γ, - 178.98 ± 1.74 and did not differ significantly. The highest recorded temperatures were: α, - 165.14 °C; ß, - 157.41 °C; γ, - 164.45 °C. A total of 1064 automation transactions on 409 specimen vessels were performed. Data was managed on 1501 eggs and embryos. The ID did not lose or misplace any specimen data or vessels, and no mock specimen was exposed to a detrimental (> - 150 °C) temperature excursion. Over the 25 LN2 pressure builder usages during 99 total days, there was 1 occurrence where usage interrupted workflow due to a lack of LN2 pressure. The ID has advantages over the current manual-based cryostorage systems, including radio frequency identification (RFID) tracking, automation of manual tasks, and software guidance to ensure accurate specimen storage and retrieval. The results of this study indicate that the ID can be integrated into active IVF laboratories.

Optimizing oocyte yield utilizing a machine learning model for dose and trigger decisions, a multi-center, prospective study.

The objective of this study was to evaluate clinical outcomes for patients undergoing IVF treatment where an artificial intelligence (AI) platform was utilized by clinicians to help determine the optimal starting dose of FSH and timing of trigger injection. This was a prospective clinical trial with historical control arm. Four physicians from two assisted reproductive technology treatment centers in the United States participated in the study. The treatment arm included patients undergoing autologous IVF cycles between December 2022-April 2023 where the physician use AI to help select starting dose of follicle stimulating hormone (FSH) and trigger injection timing (N = 291). The control arm included historical patients treated where the same doctor did not use AI between September 2021 and September 2022. The main outcome measures were total FSH used and average number of mature metaphase II (MII) oocytes. There was a non-significant trend towards improved patient outcomes and a reduction in FSH with physician use of AI. Overall, the average number of MIIs in the treatment vs. control arm was 12.20 vs 11.24 (improvement = 0.96, p = 0.16). The average number of oocytes retrieved in the treatment vs. control arm was 16.01 vs 14.54 (improvement = 1.47, p = 0.08). The average total FSH in the treatment arm was 3671.95 IUs and the average in the control arm was 3846.29 IUs (difference = -174.35 IUs, p = 0.13). These results suggests that AI can safely assist in refining the starting dose of FSH while narrowing down the timing of the trigger injection during ovarian stimulation, benefiting the patient in optimizing the count of MII oocytes retrieved.

Spironolactone use and oocyte maturation in patients undergoing controlled ovarian hyperstimulation.

PURPOSE: To evaluate the association between spironolactone use and controlled ovarian hyperstimulation (COH) outcomes. METHODS: Retrospective study, including patients who underwent COH. Oocyte yield and maturation rates were compared by categories of spironolactone use at the start of their cycle. RESULTS: 402 patients were included. 83 patients continued spironolactone, 44 patients discontinued spironolactone, and 275 matched control patients were spironolactone-naïve. No difference was observed in the number of oocytes retrieved (17 ± 14 vs. 15 ± 13, p = 0.4) or mature oocytes vitrified (15 ± 9.5 vs. 12 ± 11, p = 0.4) in patients who continued spironolactone use and spironolactone naïve patients, respectively. When comparing patients who continued spironolactone use and patients who discontinued spironolactone use, no difference was seen in the number of oocytes retrieved (17 ± 14 vs. 17.5 ± 7.8, p = 0.9) or mature oocytes vitrified (15 ± 9.5 vs. 13.5 ± 6.5, p = 0.5), respectively. There was no observed relationship between total daily spironolactone dose (< 100mg/day, 100mg/day, 150mg/day and > 200 mg/day) and the total number of mature oocytes vitrified (respectively, 14.0 ± 13.0, 16.0 ± 7.8, 14.0 ± 4.5, 11.0 ± 7.0 oocytes, p = 0.4). CONCLUSIONS: This is the first study to evaluate the association between spironolactone and oocyte yield and maturation rates during COH cycles. These findings can assist in counseling patients on the implications of continuing spironolactone during COH cycle.

Obstetric outcomes of nulliparous women with pelvic pain undergoing fertility treatment.

RESEARCH QUESTION: Is there any association between pelvic pain and primary caesarean delivery for patients undergoing assisted reproductive technology (ART) treatment? DESIGN: Retrospective cohort study of nulliparous patients with singleton pregnancies who underwent ART treatment and achieved a live birth between 2012 and 2020. Cases included patients diagnosed with pelvic pain. A 3:1 ratio propensity-score-matched population of patients without a history of pelvic pain was included as the control group. Comparative statistics were performed using chi-squared test and Student's t-test. A multivariate regression analysis was conducted to evaluate the association between pelvic pain and mode of delivery. RESULTS: One hundred and seventy-four patients with pelvic pain were compared with 575 controls. Patients with pelvic pain reported a significantly longer duration of infertility compared with controls (18.98 ± 20.2 months versus 14.06 ± 14.06 months; P = 0.003). Patients with pelvic pain had a significantly higher rate of anxiety disorders (115 ± 21.9 versus 55 ± 31.6; P = 0.009) and use of anxiolytics at embryo transfer (17 ± 3.2 versus 12 ± 6.9; P = 0.03) compared with controls. In addition, patients with pelvic pain had a higher rate of primary caesarean delivery compared with controls (59.8% versus 49.0%; P = 0.01). After adjusting for multiple variables, a significant association was found between pelvic pain and increased odds of primary caesarean delivery (adjusted OR 1.48, 95% CI 1.02-2.1). CONCLUSION: Patients with pelvic pain have significantly higher odds of primary caesarean delivery compared with patients without a history of pelvic pain. The infertility outpatient setting may be uniquely positioned to identify patients at risk for undergoing primary caesarean delivery, and could facilitate earlier intervention for pelvic floor physical therapy during the preconception and antepartum periods.

Rescue in vitro maturation using ovarian support cells of human oocytes from conventional stimulation cycles yields oocytes with improved nuclear maturation and transcriptomic resemblance to in vivo matured oocytes.

PURPOSE: Determine if the gene expression profiles of ovarian support cells (OSCs) and cumulus-free oocytes are bidirectionally influenced by co-culture during in vitro maturation (IVM). METHODS: Fertility patients aged 25 to 45 years old undergoing conventional ovarian stimulation donated denuded immature oocytes for research. Oocytes were randomly allocated to either OSC-IVM culture (intervention) or Media-IVM culture (control) for 24-28 h. The OSC-IVM culture condition was composed of 100,000 OSCs in suspension culture with human chorionic gonadotropin (hCG), recombinant follicle stimulating hormone (rFSH), androstenedione, and doxycycline supplementation. The Media-IVM control lacked OSCs and contained the same supplementation. A limited set of in vivo matured MII oocytes were donated for comparative evaluation. Endpoints consisted of MII formation rate, morphological and spindle quality assessment, and gene expression analysis compared to in vitro and in vivo controls. RESULTS: OSC-IVM resulted in a statistically significant improvement in MII formation rate compared to the Media-IVM control, with no apparent effect on morphology or spindle assembly. OSC-IVM MII oocytes displayed a closer transcriptomic maturity signature to IVF-MII controls than Media-IVM control MII oocytes. The gene expression profile of OSCs was modulated in the presence of oocytes, displaying culture- and time-dependent differential gene expression during IVM. CONCLUSION: The OSC-IVM platform is a novel tool for rescue maturation of human oocytes, yielding oocytes with improved nuclear maturation and a closer transcriptomic resemblance to in vivo matured oocytes, indicating a potential enhancement in oocyte cytoplasmic maturation. These improvements on oocyte quality after OSC-IVM are possibly occurring through bidirectional crosstalk of cumulus-free oocytes and ovarian support cells.

Walking the tightrope: Fertility preservation among hereditary breast and ovarian Cancer syndrome Previvors.

INTRODUCTION: Fertility-related concerns cause significant anxiety among patients with Hereditary Breast and Ovarian Cancer Syndrome (HBOC). The Society of Gynecologic Oncology and the American Society for Reproductive Medicine recommend patients diagnosed with HBOC receive early referral to a reproductive endocrinologist. However, evidence about fertility trends in this patient population are limited and guidelines are scarce. The aim of this study is to compare fertility preservation among patients with HBOC to control patients undergoing fertility treatment without a diagnosis of infertility. METHODS: This retrospective study included patients who presented to a single academic institution for fertility preservation in the setting of diagnosis of HBOC. In this study, HBOC patients are referred to as those who had tested positive for pathogenic mutations in BRCA1, BRCA2 or were at high-risk for HBOC based on a strong family history (defined as >3 family members diagnosed with HBOC) without a genetic mutation. HBOC patients were matched in a 1:1 fashion to a control group undergoing fertility preservation without a diagnosis of infertility or HBOC. All analysis was done using SPSS version 9.4 (SAS Institute, Cary, NC). RESULTS: Between August 1st, 2016 and August 1st, 2022, 81 patients presented to the study center for consultation in the setting of HBOC. Of those who presented, 48 (59.2%) ultimately underwent oocyte cryopreservation and 33 (40.7%) underwent embryo cryopreservation. Patients who underwent oocyte cryopreservation due to BRCA1 status were more likely to present for fertility consultation at a younger age compared to control patients (32.6 vs. 34.7 years, p = 0.03) and were more likely to undergo oocyte cryopreservation at a younger age (32.1 vs. 34.6 years, p = 0.007). There was no difference in age at initial consultation or age at procedure for patients with BRCA2 or patients with a strong family history compared to control patients (p > 0.05). There was no difference in the mean age of patients with HBOC at presentation for consultation for embryo cryopreservation or the mean age the patient with HBOC underwent embryo cryopreservation compared to control patients (p > 0.05). Patients with BRCA1 or BRCA2 did not have expedited time from consultation to first cycle start (p > 0.05). After adjusting for factors including anti-Müllerian hormone (AMH) level and age, patients considered in the HBOC group due to family history had less time between consultation and oocyte cryopreservation cycle compared to control patients. (179 vs. 317 days, p = 0.045). There was no difference in time from consultation to starting cycle for embryo cryopreservation for patients with HBOC compared to controls (p > 0.05). CONCLUSION: Patients with HBOC did not undergo expedited fertility treatment compared to control patients undergoing oocyte and embryo cryopreservation for non-infertility reasons. Patients diagnosed with BRCA1 had more oocytes retrieved compared to the control population which is possibly due to earlier age of presentation in the setting of recommended age of risk reducing surgery being age 35-40. When age matched, cycle outcomes did not differ between HBOC and control patients. Given the known cancer prevention benefit and recommendations for risk-reducing surgery, future studies should focus on guidelines for fertility preservation for patients with HBOC.

Medicare meets the cloud: the development of a secure platform for the storage and analysis of claims data.

Introduction: Cloud-based solutions are a modern-day necessity for data intense computing. This case report describes in detail the development and implementation of Amazon Web Services (AWS) at Emory-a secure, reliable, and scalable platform to store and analyze identifiable research data from the Centers for Medicare and Medicaid Services (CMS). Materials and Methods: Interdisciplinary teams from CMS, MBL Technologies, and Emory University collaborated to ensure compliance with CMS policy that consolidates laws, regulations, and other drivers of information security and privacy. Results: A dedicated team of individuals ensured successful transition from a physical storage server to a cloud-based environment. This included implementing access controls, vulnerability scanning, and audit logs that are reviewed regularly with a remediation plan. User adaptation required specific training to overcome the challenges of cloud computing. Conclusion: Challenges created opportunities for lessons learned through the creation of an end-product accepted by CMS and shared across disciplines university-wide.

Family Building in Transgender Patients: Modern Strategies with Assisted Reproductive Technology Treatment.

Purpose: Transgender and gender diverse (TGD) individuals continue to face adversity, stigma, and inequality, especially in health care. This study aimed to characterize the experience of TGD people and partners of TGD people with regard to fertility treatment. Methods: All TGD patients presenting to a single academic center between 2013 and 2021 were included. Baseline demographics collected included patient age, body mass index, anti-Mullerian hormone, basal antral follicle count, history of gender-affirming surgery, and/or gender-affirming hormone therapy. Outcomes included total patients who progressed to treatment, cycle type(s), and clinical outcomes. Results: In total, 82 patients who identified as TGD or had a partner who identified as TGD presented to care seeking fertility treatment. Of the 141 planned cycles, 106 (75.2%) progressed to treatment. Of the 15 in vitro fertilization (IVF) and co-IVF cycles, 12 achieved live birth. Of the 76 intrauterine inseminations 7 patients were discharged with ongoing pregnancies and one achieved live birth. Conclusion: These findings reaffirm that TGD individuals utilize the entire array of fertility services. With recent advances in access to care and modern medicine, assisted reproductive technology treatment has the power to support TGD patients in building contemporary family structures.

Single Euploid Embryo Transfer Outcomes After Uterine Septum Resection.

STUDY OBJECTIVE: To study pregnancy outcomes after single euploid embryo transfer (SEET) in patients who underwent prior uterine septum resection to those with uteri of normal contour, without Müllerian anomalies or uterine abnormalities including polyps or fibroids, and without a history of prior uterine surgeries. DESIGN: Retrospective cohort study. SETTING: Single academic affiliated center. PATIENTS: 60 cycles of patients with prior hysteroscopic uterine septum resection who underwent an autologous SEET between 2012 and 2020 were used as the investigational cohort. A 3:1 ratio propensity score matched control cohort of 180 single euploid embryo transfer cycles from patients without a history of uterine septa were used as the control group. INTERVENTIONS: No interventions administered. MEASUREMENTS AND MAIN RESULTS: Pregnancy, clinical pregnancy loss, ongoing clinical pregnancy, and live birth rates in patients with a history of uterine septum resection compared with matched patients without Müllerian anomalies or uterine surgeries. Patients with a prior uterine septum had significantly lower rates of chemical pregnancy (58.33% vs 77.2%, p = .004), implantation (41.67% vs 65.6%, p = .001), and live birth (33.33% vs 57.8%, p = .001) per transfer. No statistical difference in clinical pregnancy loss rates was found when comparing septum patients with controls (8.33% vs 7.8%, p = .89). CONCLUSION: Patients with a history of hysteroscopic resection who undergo in vitro fertilization are more susceptible to suboptimal clinical outcomes compared with patients with normal uteri. Early pregnancy loss rates in patients with a uterine septum are higher than in those without; however, after resection, the rates are comparable. Patients born with septate uteri require assessment of surgical intervention prior to SEET, and to optimize their reproductive outcomes.

Assessing the clinical viability of micro 3 pronuclei zygotes.

PURPOSE: What is the rate of euploidy and clinical viability of embryos resulting from micro 3 pronuclei zygotes? METHODS: Retrospective cohort analysis in a single, academic in vitro fertilization (IVF) center from March 2018 to June 2021. Cohorts were separated by fertilization as either a 2 pronuclear zygote (2PN) or micro 3 pronuclear zygote (micro 3PN). PGT-A was performed to identify embryonic ploidy rates in embryos created from micro 3PN zygotes. The clinical outcomes of all transferred euploid micro 3PN zygotes were evaluated from frozen embryo transfer (FET) cycles. RESULTS: During the designated study period, 75,903 mature oocytes were retrieved and underwent ICSI. Of these, 60,161 were fertilized as 2PN zygotes (79.3%) and 183 fertilized as micro 3PN zygotes (0.24%). Of the micro 3PN-derived embryos that underwent biopsy, 27.5% (n=11/42) were deemed euploid by PGT-A, compared to 51.4% (n=12,301/23,923) of 2PN-derived embryos, p=0.06. Four micro 3PN-derived embryos were transferred in subsequent single euploid FET cycles, which includes one live birth and one ongoing pregnancy. CONCLUSION: Micro 3PN zygotes that develop to the blastocyst stage and meet the criteria for embryo biopsy have the potential to be euploid by preimplantation genetic testing for aneuploidy (PGT-A) and if selected for transfer can achieve a live birth. Although there are a significantly lower number of micro 3PN embryos that make it to blastocyst biopsy, the potential to continue to culture abnormally fertilized oocytes may give these patients a chance at pregnancy that they previously did not have.

Assisted Reproductive Technology Treatment Outcomes in Women With Liver Disease.

INTRODUCTION: There is a need for evidence-based counseling for women with chronic liver disease (LD) who may experience impaired fertility. Currently, the literature on assisted reproductive technology (ART) treatment in women with LD has been limited to a single European case series. We evaluated ART treatment outcomes in patients with LD and compared with controls. METHODS: The retrospective study evaluated women with and without LD who had normal ovarian reserve and underwent ART treatment in a high-volume fertility practice from 2002 to 2021. RESULTS: We identified 295 women with LD (mean age 37.8 ± 5.2 years) who underwent 1,033 ART treatment cycles; of these women, 115 underwent 186 in vitro fertilization (IVF) cycles. Six women (2.0%) had cirrhosis, 8 (2.7%) were postliver transplantation, and 281 (95.3%) had chronic LD, with viral hepatitis (B and C) being the most prevalent. In the subgroup who underwent IVF and embryo biopsy, the median fibrosis-4 score was 0.81 (0.58-1.03), and there were no statistically significant differences in response to controlled ovarian stimulation, embryo fertilization rate, or ploidy outcome in patients with LD compared with controls. In those who subsequently underwent a single thawed euploid embryo transfer to achieve pregnancy, there were no statistically significant differences in rates of clinical pregnancy, clinical pregnancy loss, or live birth in patients with LD compared with controls. DISCUSSION: To the best of our knowledge, this study is the largest to date to evaluate IVF efficacy in women with LD. Our study demonstrates that patients with LD have similar ART treatment outcomes compared with those without LD.

Fertility treatment outcomes in transgender men with a history of testosterone therapy.

Objective: To evaluate fertility treatment outcomes among transgender (TG) men with a history of gender-affirming hormone therapy with exogenous testosterone. Design: Descriptive, retrospective cohort study. Patients: Transgender men with a history of gender-affirming hormone therapy with exogenous testosterone underwent fertility treatments, including embryo cryopreservation, in vitro fertilization (IVF), co-IVF, oocyte cryopreservation, and intrauterine insemination (IUI), between 2013 and 2021. Intervention: Gender-affirming hormone therapy with testosterone. Main Outcome Measures: Live births (LBs), number of frozen embryos, and number of frozen oocytes. Other outcome measures included total gonadotropin used, peak estradiol levels, oocytes retrieved, oocyte maturity rate, fertilization rate, and embryo grade. Results: A total of 77 TG men self-presented or were referred to care at a single academic fertility center, of which 46 (59.7%) TG men underwent fertility preservation and/or family-building counseling, with 16 (20.8%) patients proceeding to fertility treatment. Of those patients who underwent treatment, 11 (68.8%) had a history of gender-affirming hormone therapy with exogenous testosterone use. Cohort 1 included IVF (n = 1), co-IVF (n = 1), embryo cryopreservation (n = 2), cohort 2 included oocyte cryopreservation (n = 4), and cohort 3 included IUI (n = 3). In cohort 1, both the patients who underwent IVF and the patients who underwent co-IVF achieved LBs. All embryo cryopreservation cycles froze three or more embryos. In cohort 2, the average number of frozen mature oocytes was 19.3 ± 16.2 (range 6-43). All patients who underwent IUI cycles achieved LB. Conclusion: In this study, no correlation existed between patient age, time on or off gender-affirming hormone therapy with exogenous testosterone, total gonadotropin used, and number of oocytes retrieved. All patients who completed IVF or embryo cryopreservation produced high-quality blastocytes, and this is the first study to show successful IUI cycles in patients with a history of gender-affirming hormone therapy with exogenous testosterone. This study demonstrates that TG men who have used gender-affirming hormone therapy previously can successfully undergo fertility treatments to attain oocyte and embryo cryopreservation, pregnancy, and LBs.

Pathways to fatherhood: clinical experiences with assisted reproductive technology in single and coupled intended fathers.

Objective: To explore the cycle characteristics and outcomes of single and coupled intended fathers (SCIFs) using assisted reproductive technology. Design: Cross-sectional study. Setting: Multicenter, fertility practices from 2016 to 2020. Patients: In this study, cycles among SCIFs with access to fertility coverage from 2016 to 2020 were included. Interventions: None. Main Outcome Measures: Our primary outcome was live birth rate. The secondary outcomes included the number of embryos transferred, miscarriage rate, and incidence of multifetal birth. Results: Five single and 39 coupled intended fathers completed an in vitro fertilization cycle with a majority using egg donation and an agency-based gestational carrier (69.7%, 83/119). In most couples, both partners wanted to serve as the sperm source (64.4%, 29/45). The vast majority (97.7%, 43/44) also used preimplantation genetic testing for aneuploidy. Among the embryo transfer (ET) cycles (n = 27), most consisted of a single euploid ET (74.07%, 20/27), whereas the remaining consisted of a double euploid ET (25.92%, 7/27). The SCIFs had high rates of success, with a live birth rate of 85.19% (23/27). A mean of 1.26 ± 0.44 embryos were transferred, with a majority resulting in singleton birth (70.37%, 19/27). Conclusions: Our study of SCIFs using assisted reproductive technology in the United States demonstrates that this population shares similar preferences for sperm source and the use of preimplantation genetic testing. Clinical outcomes suggest that this population is successful at achieving a live birth when using egg donation and a gestational carrier.

Association of Myomectomy With Anti-Müllerian Hormone Levels and Ovarian Reserve.

OBJECTIVE: To assess whether open and minimally invasive myomectomy are associated with changes in postoperative ovarian reserve as measured by serum anti-müllerian hormone (AMH) level. METHODS: This prospective cohort study included patients who were undergoing open abdominal myomectomy that used a tourniquet or minimally invasive (robot-assisted or laparoscopic) myomectomy that used vasopressin. Serum AMH levels were collected before the procedure and at 2 weeks, 3 months, and 6 months after surgery. The mean change in AMH level at each postsurgery timepoint was compared with baseline. The effect of surgical route on the change in AMH level at each timepoint was assessed by using multivariable linear regression. A subanalysis evaluated postoperative changes in AMH levels among the open myomectomy and minimally invasive myomectomy groups individually. RESULTS: The study included 111 patients (mean age 37.9±4.7 years), of whom 65 underwent open myomectomy and 46 underwent minimally invasive myomectomy. Eighty-seven patients contributed follow-up data. Serum AMH levels declined significantly at 2 weeks postsurgery (mean change -0.30 ng/mL, 95% CI -0.48 to -0.120 ng/mL, P=.002). No difference was observed at 3 months or 6 months postsurgery. On multiple linear regression, open myomectomy was significantly associated with a decline in AMH level at 2 weeks postsurgery (open myomectomy vs minimally invasive myomectomy: ß=-0.63±0.22 ng/mL, P=.007) but not at 3 months or 6 months. Subanalysis revealed a significant decline in mean serum AMH levels in the open myomectomy group at 2 weeks (mean change -0.46 ng/mL, 95% CI -0.69 to -0.25 ng/mL, P<.001) postsurgery but not at three or 6 months. In the minimally invasive myomectomy group, no significant differences in mean AMH levels were detected between baseline and any postoperative timepoint. CONCLUSION: Myomectomy is associated with a transient decline in AMH levels in the immediate postoperative period, particularly after open surgery in which a tourniquet is used. Anti-müllerian hormone levels returned to baseline by 3 months after surgery, indicating that myomectomy is not associated with a long-term effect on ovarian reserve, even with the use of a tourniquet to decrease blood loss. FUNDING SOURCE: This study was funded in part by a Roche Diagnostics Investigator-Initiated Study Grant.

Elevated Body Mass Index in Donor Oocyte Recipients Does Not Affect Implantation of Euploid Embryos.

Background: Obesity is a worldwide epidemic that has been shown to have serious implications on health outcomes. Regarding reproductive health, increased body mass index (BMI) reduces fertility and increases the time to conceive. It is unclear how excess weight in females affects the development of oocytes and embryos or the impact of implantation. Materials and Methods: This retrospective single-center study aimed to determine if overweight and obese oocyte recipients had similar pregnancy outcomes compared with healthy weight controls after the transfer of a single euploid frozen-thawed embryo transfer (FET). Five hundred twenty-eight patients who underwent a transfer from 2016 to 2021 were included. The primary outcome studied was the clinical pregnancy (CP) rate. Secondary outcomes included live birth (LB) rate, biochemical pregnancy loss (BPL) rate, and clinical pregnancy loss (CPL) rate. Results: The overall CP rate was 54.9% and did not differ significantly among normal weight (n = 318), overweight (n = 129), and obese (n = 81) BMI categories (0.56 vs. 0.56 vs. 0.49, p = 0.56). There were no significant differences in LB rate (0.47 vs. 0.43 vs. 0.38, p = 0.33), BPL rate (0.14 vs. 0.09 vs. 0.11, p = 0.59), and CPL rate (0.15 vs. 0.21 vs. 0.18, p = 0.38) among BMI groups. Conclusions: Our findings provide support that BMI alone does not adversely alter endometrial receptivity and is not the cause of poor in vitro fertilization (IVF) outcomes in patients with increased BMI. These deleterious IVF outcomes might be to the result of diminished oocyte and/or embryo quality or other factors that have not yet been elucidated.

In Vitro Fertilization and Early Pregnancy Outcomes After Coronavirus Disease 2019 (COVID-19) Vaccination.

OBJECTIVE: To assess whether coronavirus disease 2019 (COVID-19) mRNA vaccination is associated with controlled ovarian hyperstimulation or early pregnancy outcomes. METHODS: This retrospective cohort study included patients who underwent controlled ovarian hyperstimulation or single euploid frozen-thawed embryo transfer at a single academic center. Patients fully vaccinated with a COVID-19 mRNA vaccine were compared with unvaccinated patients who cycled during the same time period. The primary outcome was the fertilization rate for controlled ovarian hyperstimulation and the clinical pregnancy rate for frozen-thawed embryo transfer. Secondary outcomes for controlled ovarian hyperstimulation included eggs retrieved, mature oocytes retrieved, mature oocytes ratio, blastulation rate, and euploid rate. Secondary outcomes for frozen-thawed embryo transfer included pregnancy rate, ongoing pregnancy rate, biochemical pregnancy loss rate, and clinical pregnancy loss rate. RESULTS: Among 222 vaccinated patients and 983 unvaccinated patients who underwent controlled ovarian hyperstimulation cycles between February and September 2021, there was no association on adjusted analysis between COVID-19 vaccination and fertilization rate (ß=0.02±0.02, P=.20) or any of the secondary outcomes assessed: eggs retrieved (ß=0.01±0.57, P=.99), mature oocytes retrieved (ß=0.26±0.47, P=.58), mature oocytes ratio (ß=0.02±0.01, P=.12), blastulation rate (ß=0.02±0.02, P=.27), or euploid rate (ß=0.05±0.03, P=.08). Among 214 vaccinated patients and 733 unvaccinated patients undergoing single euploid frozen-thawed embryo transfer, adjusted analysis demonstrated no significant association between vaccination and clinical pregnancy (adjusted odds ratio [aOR] 0.79, 95% CI 0.54-1.16) or any of the secondary outcomes: pregnancy (aOR 0.88, 95% CI 0.58-1.33), ongoing pregnancy (aOR 0.90, 95% CI 0.61-1.31), biochemical pregnancy loss (aOR 1.21, 95% CI 0.69-2.14), or clinical pregnancy loss (aOR 1.02, 95% CI 0.51-2.06). CONCLUSION: Administration of COVID-19 mRNA vaccines was not associated with an adverse effect on stimulation or early pregnancy outcomes after IVF. Our findings contribute to the growing body of evidence regarding the safety of COVID-19 vaccination in women who are trying to conceive.

The Impact of the Coronavirus Disease 19 Pandemic on Early Pregnancy Outcomes Among Patients Undergoing In Vitro Fertilization Treatment.

Objective: To determine if pregnancy rates (PRs) or pregnancy loss rates (PLRs) were altered in patients undergoing single, euploid frozen-thawed embryo transfer (FET) during the initial peak of the Coronavirus Disease 19 (COVID-19) pandemic. Materials and Methods: This was a retrospective cohort study performed in a single academic center. Patients undergoing single, euploid FET cycles from January to May 2017-2020 were included. Cycles with FET performed in January-May of 2020 ("COVID-surge cohort") were compared to cycles with FET performed in January-May of 2017-2019 ("pre-COVID cohort"). Pregnancy rate (PR), clinical pregnancy rate (CPR), pregnancy loss rate (PLR), and clinical pregnancy loss rate (CLR) were compared between the cohorts. Results: A total of 2629 single, euploid FET cycles were included: 2070 from January to May, 2017-2019 and 559 from January to May 2020. PR was similar when comparing FET performed from January to May 2020 (COVID-surge) to those performed from January to May, 2017-2019 (pre-COVID) (77.6% vs. 73.7%, p = 0.06), while CPR was higher among the COVID-surge compared to the pre-COVID cohort (65.5% vs. 60.0%, p = 0.02). No differences were seen in PLR and CLR among the COVID-surge and pre-COVID cohorts (28.3% vs. 32.0%, p = 0.08; 15.0% vs. 16.5%, p = 0.50). PR, CPR, PLR, and CLR were similar when comparing individual months between the cohorts. Adjusted analysis showed no differences in PR, CPR, PLR, or CLR when comparing the cohorts overall or when comparing corresponding individual months in the two time periods. Conclusion: PRs and PLRs were not decreased when SARS-CoV-2 transmission was widespread in our geographic area, suggesting that high COVID-19 transmission does not compromise early pregnancy outcomes.

Factors associated with vitrification-warming survival in 6167 euploid blastocysts.

PURPOSE: To understand the clinical factors associated with embryo survival after vitrification in a cohort of human blastocysts screened by preimplantation genetic testing for aneuploidy (PGT-A). METHODS: Patient demographic, embryo, and cycle characteristics associated with failed euploid blastocyst survival were compared in a cohort of women (n = 6167) who underwent IVF-PGT-A. RESULTS: Compared to those that survived warming, vitrified euploid embryos that failed to survive after warming came from IVF cycles with significantly higher estradiol levels at time of surge (2754.8 ± 1390.2 vs. 2523.1 ± 1190.6 pg/mL, p = 0.03), number of oocytes retrieved (19.6 ± 10.7 vs. 17.5 ± 9.8, p = 0.005), and basal antral follicle count (BAFC) (15.3 ± 8.5 vs. 13.9 ± 7.2, p = 0.05). Euploid embryos were less likely to survive warming if they came from cycles before 2015 (24.6% vs. 13.2%, p < 0.001), were cryopreserved on day 7 versus day 5 or 6 (9.1% vs. 3.0%, p < 0.001), underwent two trophectoderm biopsies (6.9% vs. 2.3%, p < 0.001), had a grade C inner cell mass (15.4% vs. 7.7%, p < 0.001), or were fully hatched (41.1% vs. 12.2%, p < 0.001). In the multivariate model, which controlled for relevant confounders, the association between decreased survival and increased BAFC, year of IVF cycle, double trophectoderm biopsy, and fully hatched blastocysts remained statistically significant. CONCLUSION: Euploid embryos that are fully hatched at time of vitrification, come from patients with high ovarian reserve, or require repeat trophectoderm biopsy are less likely to survive vitrification-warming. Our results provide a framework for reproductive counseling and offer realistic expectations to patients about the number of embryos needed to achieve family building goals.

Clinical implementation of algorithm-based embryo selection is associated with improved pregnancy outcomes in single vitrified warmed euploid embryo transfers.

PURPOSE: To assess whether utilization of a mathematical ranking algorithm for assistance with embryo selection improves clinical outcomes compared with traditional embryo selection via morphologic grading in single vitrified warmed euploid embryo transfers (euploid SETs). METHODS: A retrospective cohort study in a single, academic center from September 2016 to February 2020 was performed. A total of 4320 euploid SETs met inclusion criteria and were included in the study. Controls included all euploid SETs in which embryo selection was performed by a senior embryologist based on modified Gardner grading (traditional approach). Cases included euploid SETs in which embryo selection was performed using an automated algorithm-based approach (algorithm-based approach). Our primary outcome was implantation rate. Secondary outcomes included ongoing pregnancy/live birth rate and clinical loss rate. RESULTS: The implantation rate and ongoing pregnancy/live birth rate were significantly higher when using the algorithm-based approach compared with the traditional approach (65.3% vs 57.8%, p<0.0001 and 54.7% vs 48.1%, p=0.0001, respectively). After adjusting for potential confounding variables, utilization of the algorithm remained significantly associated with improved odds of implantation (aOR 1.51, 95% CI 1.04, 2.18, p=0.03) ongoing pregnancy/live birth (aOR 1.99, 95% CI 1.38, 2.86, p=0.0002), and decreased odds of clinical loss (aOR 0.42, 95% CI 0.21, 0.84, p=0.01). CONCLUSIONS: Clinical implementation of an automated mathematical algorithm for embryo ranking and selection is significantly associated with improved implantation and ongoing pregnancy/live birth as compared with traditional embryo selection in euploid SETs.
