RESUMO
PURPOSE: To develop an innovative machine learning (ML) model that predicts personalized risk of primary ovarian insufficiency (POI) after chemotherapy for reproductive-aged women. Currently, individualized prediction of a patient's risk of POI is challenging. METHODS: Authors of published studies examining POI after gonadotoxic therapy were contacted, and six authors shared their de-identified data (N = 435). A composite outcome for POI was determined for each patient and validated by 3 authors. The primary dataset was partitioned into training and test sets; random forest binary classifiers were trained, and mean prediction scores were computed. Institutional data collected from a cross-sectional survey of cancer survivors (N = 117) was used as another independent validation set. RESULTS: Our model predicted individualized risk of POI with an accuracy of 88% (area under the ROC 0.87, 95% CI: 0.77-0.96; p < 0.001). Mean prediction scores for patients who developed POI and who did not were 0.60 and 0.38 (t-test p < 0.001), respectively. Highly weighted variables included age, chemotherapy dose, prior treatment, smoking, and baseline diminished ovarian reserve. CONCLUSION: We developed an ML-based model to estimate personalized risk of POI after chemotherapy. Our web-based calculator will be a user-friendly decision aid for individualizing risk prediction in oncofertility consultations.

PURPOSE: In December 2019, the American Society for Reproductive Medicine designated ovarian tissue cryopreservation (OTC) as no longer experimental and an alternative to oocyte cryopreservation (OC) for women receiving gonadotoxic therapy. Anticipating increased use of OTC, we compare the cost-effectiveness of OC versus OTC for fertility preservation in oncofertility patients. METHODS: A cost-effectiveness model to compare OC versus OTC was built from a payer perspective. Costs and probabilities were derived from the literature. The primary outcome for effectiveness was the percentage of patients who achieved live birth. Strategies were compared using incremental cost-effectiveness ratios (ICER). All inputs were varied widely in sensitivity analyses. RESULTS: In the base case, the estimated cost for OC was $16,588 and for OTC $10,032, with 1.56% achieving live birth after OC, and 1.0% after OTC. OC was more costly but more effective than OTC, with an ICER of $1,163,954 per live birth. In sensitivity analyses, OC was less expensive than OTC if utilization was greater than 63%, cost of OC prior to chemotherapy was less than $8100, cost of laparoscopy was greater than $13,700, or standardized discounted costs were used. CONCLUSIONS: With current published prices and utilization, OC is more costly but more effective than OTC. OC becomes cost-saving with increased utilization, when cost of OC prior to chemotherapy is markedly low, cost of laparoscopy is high, or standardized discounted oncofertility pricing is assumed. We identify the critical thresholds of OC and OTC that should be met to deliver more cost-effective care for oncofertility patients.

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.

Objective: To assess recall bias by evaluating how well female cancer survivors remember details regarding their cancer diagnosis, treatment, and fertility preservation (FP) counseling.Oncofertility literature cites recall bias as a pitfall of retrospective surveys, but limited data exist to quantify this bias. Design: Retrospective secondary analysis of cross-sectional survey data. Setting: Single academic medical center. Patients: Female oncology patients of reproductive age, 18-44 years old, at least 6 months past their last chemotherapy treatment. Interventions: Not applicable. Main Outcome Measures: Recall of details surrounding cancer diagnosis and chemotherapy regimens, recall of FP counseling and ovarian reserve testing, and rates of chart-documented FP counseling. Results: In total, 117 patients completed the survey, with 112 verified via chart review. When asked to report the chemotherapy regimen, 57% (64 of the 112) marked "I don't know/prefer not to say." Regarding FP, 80% (90 of the 112) denied being offered counseling. Of the 37 (33%) who had documented FP conversations, 13 (35%) did not recall mention of fertility. Only 2 of 8 patients with ovarian reserve testing recalled this being performed at their initial visit. Multivariable logistic regression revealed older age was significantly associated with not being offered FP (odds ratio [OR] 0.87). Conclusions: Our results confirm that the accuracy of oncology patients' reporting is limited by a poor recall, particularly regarding their specific chemotherapy regimen. More than 1 in 3 patients documented to have been offered FP counseling do not recall this discussion. Importantly, only one-third of cancer survivors had chart-documented FP counseling. Increased efforts are needed to ensure adequate follow-up beyond the initial visit.
RESUMO
Objective: To evaluate the association between body mass index (BMI) and good perinatal outcomes after in vitro fertilization (IVF) among women with polycystic ovary syndrome (PCOS). Design: Retrospective cohort study using 2012-2015 Society for Assisted Reproductive Technology Clinic Outcomes Reporting System data. Setting: Fertility clinics. Patients: To identify patients most likely to have PCOS, we included women with a diagnosis of ovulation disorder and serum antimüllerian hormone >4.45 ng/mL. Exclusion criteria included age ≥ 41 years, secondary diagnosis of diminished ovarian reserve, preimplantation genetic testing, and missing BMI or primary outcome data. Interventions: None. Main Outcome Measures: Good perinatal outcome, defined as a singleton live birth at ≥ 37 weeks with birth weight ≥ 2,500 g and ≤ 4,000 g. Results: The analysis included 9,521 fresh, autologous IVF cycles from 8,351 women. Among women with PCOS, the proportion of cycles with a good perinatal outcome was inversely associated with BMI: underweight 25.1%, normal weight 22.7%, overweight 18.9%, class I 18.4%, class II 14.9%, and class III or super obesity 12.2%. After adjusting for confounders, women in the highest BMI category had 51% reduced odds of a good perinatal outcome compared with normal weight women (adjusted odds ratio 0.49, 95% confidence interval 0.36-0.67). Conclusions: Among women with PCOS undergoing fresh, autologous IVF, the odds of a good perinatal outcome decline with increasing BMI. Women with PCOS should be counseled that the odds of achieving a good perinatal outcome decrease as their weight increases.
RESUMO
Objective: The objective of our study was to assess the association between AMH and live birth among women with elevated AMH undergoing first fresh IVF. Serum antimüllerian hormone (AMH) correlates with oocyte yield during in vitro fertilization (IVF). However, there are limited data regarding IVF outcomes in women with elevated AMH levels. Design: Retrospective cohort study using the Society for Assisted Reproductive Technology Clinical Outcomes Reporting System database from 2012-2014. Setting: Fertility clinics reporting to Society for Assisted Reproductive Technology. Patients: First, fresh, autologous IVF cycles with elevated AMH levels (≥5.0 ng/mL). Subanalyses were performed to examine patients with or without polycystic ovary syndrome (PCOS). Interventions: None. Main Outcome Measures: Odds of live birth. Results: Our cohort included 10,615 patients with elevated an AMH level, including 2,707 patients with PCOS only. The adjusted odds of live birth per initiated cycle were significantly lower per each unit increase in the AMH level (odds ratio, 0.97; 95% confidence interval, 0.96-0.98). Increasing AMH level was associated with increased cancellation of fresh transfer (odds ratio, 1.12; 95% confidence interval, 1.10-1.15) up to an AMH level of 12 ng/mL. The decrease in the live birth rate appears to be caused by the increasing incidence of cancellation of fresh transfer because the live birth rate per completed transfer was maintained. Similar trends were observed in the PCOS and non-PCOS subanalyses. Conclusions: Among patients with AMH levels of ≥5 ng/mL undergoing fresh, autologous IVF, each unit increase in AMH level is associated with a 3% decrease in odds of live birth because of the increased incidence of fresh embryo transfer cancellation.
RESUMO
OBJECTIVE: To examine the association between serum antimüllerian hormone (AMH) and live birth among women aged ≥41 years undergoing in vitro fertilization (IVF). DESIGN: Retrospective cohort study using the 2012-2014 Society for Assisted Reproductive Technology Clinic Outcome Reporting System database. SETTING: Fertility clinics reporting to the Society for Assisted Reproductive Technology. PATIENTS: The analysis included 7,819 patients aged ≥41 years who underwent a first fresh, autologous IVF cycle during the study period. Cycles with preimplantation genetic testing were excluded. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Live birth rate. RESULTS: The empirical distribution of AMH was examined, and extreme values were observed. Therefore, the natural logarithm transformation of AMH (log-AMH) was used in all analyses. Before adjustment for covariates, a one-unit increase in log-AMH was associated with doubling of the odds of live birth up to a log-AMH of -0.34 (equivalently, AMH, 0.71 ng/mL; odds ratio [OR], 2.02; 95% confidence interval [CI], 1.66-2.46). Above an AMH level of 0.71 ng/mL, the odds of live birth increased by only 40% with each unit increase in log-AMH (OR, 1.40; 95% CI, 1.22-1.61). After adjusting for covariates, the odds of live birth increased by 91% with each unit increase in log-AMH up to -0.34 (AMH, 0.71 ng/mL; OR, 1.91; 95% CI, 1.56-2.34). Above an AMH level of 0.71 ng/mL, the odds of live birth increased by only 32% with each unit increase in log-AMH (OR, 1.32; 95% CI, 1.15-1.53). CONCLUSIONS: Among women aged ≥41 years undergoing fresh, autologous IVF, the odds of live birth significantly increase with increasing serum AMH level. As the AMH level increases above 0.71 ng/mL, the association maintains statistical significance, but the effect size is diminished.
RESUMO
BACKGROUND: Infertility is a common late effect for cancer survivors. Whereas assisted reproductive technology has made it possible for survivors to take steps to preserve fertility before starting treatment, only a minority of patients proceed with preservation. Patient-, provider-, health system-, and societal-level barriers to fertility preservation (FP) exist. Oncofertility patient navigation is a valuable resource for addressing FP barriers. OBJECTIVES: To highlight the critical role of oncofertility patient navigation in addressing barriers to FP within an academic oncofertility program. METHODS: The role of the oncofertility patient navigator in reducing FP barriers, promoting informed decision-making, and ensuring program sustainability is described. Program metrics illustrating the impact of oncofertility patient navigation on referrals for FP counseling and access to FP in the last year also are provided. DISCUSSION: The oncofertility program at our academic adult and pediatric medical centers aims to facilitate rapid referral to fertility counseling and preservation services for postpubertal cancer patients. The patient navigator is integral to the success of the program. The navigator ensures that patients are: (1) well-informed about the potential impact of cancer on fertility and FP options, (2) aware of available resources (eg, financial) for pursuing FP, (3) able to access FP services if desired, and (4) well supported in making an informed FP decision. The inclusion of the patient navigator has led to an almost 2-fold increase in referrals for FP counseling in the past year over the historic annual average. CONCLUSIONS: Our institution's oncofertility program, with patient navigation at the core, provides a potential model for increasing patient access to oncofertility care and promoting program sustainability. Oncofertility patient navigation is a valuable resource for providing patients and families with education and support regarding FP decision-making, as well as addressing the multilevel barriers to FP.
RESUMO
IMPORTANCE: Infertility poses a substantial public health problem for women of reproductive age, in the United States and globally. Infertility can be overcome with a variety of emerging assisted reproductive technologies (ARTs). In vitro fertilization (IVF) currently represents the most commonly utilized method of ART and is typically associated with the highest clinical pregnancy rate and live birth rate compared with other infertility treatment options. However, proper preconception evaluation and counseling is paramount for optimizing IVF and pregnancy outcomes. OBJECTIVE: This article aims to outline current guidelines and recommendations for comprehensive preconception evaluation before initiation of IVF. EVIDENCE ACQUISITION: Articles were obtained from PubMed, ACOG committee opinions 781 and 762, and relevant textbook chapters. RESULTS: A variety of recommendations and best practices exist for optimally managing patients seeking IVF. Special attention must be paid to the workup of certain patient populations, such as those with age older than 35 years, uterine abnormalities, comorbidities (especially hypertension, diabetes, and thrombophilias), and obesity. In addition, many lifestyle factors must be addressed before IVF initiation, such as smoking, illicit drug use, and inadequate nutrition. Preconception counseling and expectation management is key to optimizing pregnancy outcome. CONCLUSION AND RELEVANCE: A myriad of patient and environmental factors impact the potential success rates of IVF in treating infertility. Providers must be equipped to provide data-driven, patient-centered counseling before initiation of IVF.

OBJECTIVE: Oocyte donation has optimized our understanding of ovarian stimulation. Increasing the follicle-stimulating hormone (FSH) dose has been shown to adversely affect live birth rates in autologous cycles. Our objective is to assess whether this relationship holds true within the donor/recipient population. DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENTS: Data from 2014-2016 included 8,627 fresh donor cycles. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Live birth, clinical pregnancy, and miscarriage rates. RESULTS: The mean donor age ± standard deviation (SD) was 25.8 ± 2.8 years. Donors underwent a median of 16 days (interquartile range [IQR] 12, 19) of stimulation with a median (IQR) total FSH dose and daily dose of 2,350.0 (1,800.0, 3,025.0) and 153.8 (113.2, 205.0) IU, respectively. The live birth rate was 56.7% per transfer. For every 500-unit increase in FSH dose, there was a 3% reduction in the odds of a live birth (odds ratio [OR] 0.97; 95% confidence interval 0.95, 0.99), and a 3% reduction in the odds of a clinical pregnancy (OR 0.97; 95% confidence interval 0.95, 0.99). Days of stimulation and average daily dose were not significantly associated with live birth or clinical pregnancy. No significant association was found between miscarriage rates and total FSH dose, days of stimulation, or average daily dose. CONCLUSION: This is a novel report of a negative association of total FSH dosage on fresh IVF live births, performed in the donor population to control for oocyte source and endometrial receptivity.

As marijuana legalization is increasing, research regarding possible long-term risks for users and their offspring is needed. Little data exists on effects of paternal tetrahydrocannabinol (THC) exposure prior to reproduction. This study determined if chronic THC exposure alters sperm DNA methylation (DNAm) and if such effects are intergenerationally transmitted. Adult male rats underwent oral gavage with THC or vehicle control. Differentially methylated (DM) loci in motile sperm were identified using reduced representation bisulfite sequencing (RRBS). Another cohort was injected with vehicle or THC, and sperm DNAm was analyzed. Finally, THC-exposed and control adult male rats were mated with THC-naïve females. DNAm levels of target genes in brain tissues of the offspring were determined by pyrosequencing. RRBS identified 2,940 DM CpGs mapping to 627 genes. Significant hypermethylation was confirmed (p < 0.05) following oral THC administration for cytochrome P450 oxidoreductase (Por), involved in toxin processing and disorders of sexual development. Por hypermethylation was not observed after THC injection or in the subsequent generation. These results support that THC alters DNAm in sperm and that route of exposure can have differential effects. Although we did not observe evidence of intergenerational transmission of the DNAm change, larger studies are required to definitively exclude this possibility.

OBJECTIVE: To assess in vitro fertilization (IVF) and pregnancy outcomes in patients having their first frozen embryo transfer (FET) after a freeze-all cycle versus similar patients having their first fresh embryo transfer (ET). DESIGN: Retrospective cohort study. SETTING: None. PATIENT(S): Registry data on 82,935 patient cycles from the Society for Assisted Reproductive Technology (SART). INTERVENTION(S): All first fresh autologous IVF cycles were analyzed and compared to first FET cycles after a freeze-all first IVF stimulation. The cycles were subdivided into cohorts based upon the number of oocytes retrieved (OR): 1-5 (low), 6-14 (intermediate), and 15+ (high responders). Univariate analyses were performed on cycle characteristics, and multivariable regression analyses were performed on outcome data. MAIN OUTCOME MEASURE(S): Clinical pregnancy rate (CPR) and live-birth rate (LBR). RESULTS: Of the 82,935 cycles analyzed, 69,102 patients had their first fresh transfer, and 13,833 had a first FET. High responders were found to have a higher CPR and LBR in the FET cycles compared with the fresh ET cycles (61.5 vs. 57.4%; 52.0 vs. 48.9%). In intermediate responders, both CPR and LBR were higher after fresh ET compared with FET (49.6% vs. 44.2%; 41.2 vs. 35.3%). Similarly, in low responders, CPR and LBR were higher after fresh compared with FET (33.2% vs. 15.9%; 25.9% vs. 11.5%). CONCLUSION(S): A freeze-all strategy is beneficial in high responders but not in intermediate or low responders, thus refuting the idea that freeze-all cycles are preferable for all patients.

OBJECTIVE: To analyze donor oocyte cycles in the Society for Assisted Reproductive Technology (SART) registry to determine: 1) how many cycles complied with the 2009 American Society for Reproductive Medicine/SART embryo transfer guidelines; and 2) cycle outcomes according to the number of embryos transferred. For donor oocyte IVF with donor age <35 years, the consideration of single-embryo transfer was strongly recommended. DESIGN: Retrospective cohort study of United States national registry information. SETTING: Not applicable. PATIENT(S): A total of 13,393 donor-recipient cycles from 2011 to 2012. INTERVENTION(S): Embryos transferred in donor IVF cycles. MAIN OUTCOME MEASURE(S): Percentage of compliant cycles, multiple pregnancy rate. RESULT(S): There were 3,157 donor cleavage-stage transfers and 10,236 donor blastocyst transfers. In the cleavage-stage cycles, 88% met compliance criteria. The multiple pregnancy rate (MPR) was significantly higher in the noncompliant cycles. In a subanalysis of compliant cleavage-stage cycles, 91% transferred two embryos and only 9% single embryos. In those patients transferring two embryos, the MPR was significantly higher (33% vs. 1%). In blastocyst transfers, only 28% of the cycles met compliance criteria. The MPR was significantly higher in the noncompliant blastocyst cohort at 53% (compared with 2% in compliant cycles). CONCLUSION(S): The majority of donor cleavage-stage transfers are compliant with current guidelines, but the transfer of two embryos results in a significantly higher MPR compared with single-embryo transfer. The majority of donor blastocyst cycles are noncompliant, which appears to be driving an unacceptably high MPR in these cycles.

OBJECTIVE: To examine the effect of recipient body mass index (BMI) on IVF outcomes in fresh donor oocyte cycles. DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENT(S): A total of 22,317 donor oocyte cycles from the 2008-2010 Society for Assisted Reproductive Technology Clinic Outcome Reporting System registry were stratified into cohorts based on World Health Organization BMI guidelines. Cycles reporting normal recipient BMI (18.5-24.9) were used as the reference group. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Implantation rate, clinical pregnancy rate (PR), pregnancy loss rate, live birth rate. RESULT(S): Success rates and adjusted odds ratios with 95% confidence intervals for all pregnancy outcomes were most favorable in cohorts of recipients with low and normal BMI, but progressively worsened as BMI increased. CONCLUSION(S): Success rates in recipient cycles are highest in those with low and normal BMI. Furthermore, there is a progressive and statistically significant worsening of outcomes in groups with higher BMI with respect to clinical pregnancy and live birth rate.

OBJECTIVE: To examine the effect of body mass index (BMI) on IVF outcomes in fresh autologous cycles. DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENT(S): A total of 239,127 fresh IVF cycles from the 2008-2010 Society for Assisted Reproductive Technology registry were stratified into cohorts based on World Health Organization BMI guidelines. Cycles reporting normal BMI (18.5-24.9 kg/m(2)) were used as the reference group (REF). Subanalyses were performed on cycles reporting purely polycystic ovary syndrome (PCOS)-related infertility and those with purely male-factor infertility (34,137 and 89,354 cycles, respectively). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Implantation rate, clinical pregnancy rate, pregnancy loss rate, and live birth rate. RESULT(S): Success rates and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for all pregnancy outcomes were most favorable in cohorts with low and normal BMIs and progressively worsened as BMI increased. Obesity also had a negative impact on IVF outcomes in cycles performed for PCOS and male-factor infertility, although it did not always reach statistical significance. CONCLUSION(S): Success rates in fresh autologous cycles, including those done for specifically PCOS or male-factor infertility, are highest in those with low and normal BMIs. Furthermore, there is a progressive and statistically significant worsening of outcomes in groups with higher BMIs. More research is needed to determine the causes and extent of the influence of BMI on IVF success rates in other patient populations.

OBJECTIVE: To determine whether IVF clinics are compliant with American Society for Reproductive Medicine (ASRM) and Society for Assisted Reproductive Technology (SART) (ASRM/SART) guidelines and assess the multiple pregnancy outcomes according to the number of embryos transferred. DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENT(S): Data from 59,689 fresh first autologous IVF cycles from the 2011-2012 SART registry. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Percentage of compliant cycles, multiple pregnancy rate (PR). RESULT(S): Between 2011 and 2012, a total of 59,689 fresh first autologous cycles were analyzed. Among cleavage-stage ET cycles, the noncompliance rate ranged from 10%-27.4% depending on the age group. The multiple PR was significantly increased in noncompliant cycles involving patients <35 years (38.1% vs. 28.7%) and 35-37 years (35.4% vs. 24.5%) compared with compliant cycles. Among blastocyst-stage ET cycles, the highest rate of noncompliance was seen in patients <35 years old (71%), which resulted in a statistically higher multiple PR (48.3% vs. 2.8%) compared with compliant cycles. Far fewer cycles were noncompliant in patients 35-40 years of age. In a subanalysis of compliant cycles, transferring two blastocyst embryos in patients 35-37 years and 38-40 years resulted in a higher live birth rate compared with the transfer of one embryo (50.4% vs. 40.9% and 42.1% vs. 30.0%, respectively) but the multiple PR was also significantly higher (40.5% vs. 1.7% and 34.0% vs. 2.0%, respectively). CONCLUSION(S): Most first fresh autologous IVF cycles performed from 2011-2012 were compliant with ASRM/SART guidelines, except those that involved a blastocyst ET in patients <35 years. Despite compliance, cycles that involved the transfer of >1 embryo resulted in a high multiple PR, whereas noncompliant cycles resulted in an even more remarkable multiple PR for both cleavage and blastocyst-stage embryos. Clinics need to be more compliant with ET limits and ASRM/SART need to consider revising their guidelines to limit the number of blastocyst transfer to one in patients ≤40 years of age undergoing their first IVF cycle. Furthermore, decreasing the number of cleavage-stage embryos transferred in patients ≤40 years of age should also be considered.

OBJECTIVE: To study the impact of controlled ovarian stimulation on ectopic pregnancy (EP) rate as a function of the number of oocytes retrieved, using donor IVF cycles as a control. DESIGN: Retrospective cohort study using a large national database. SETTING: Not applicable. PATIENT(S): Data from 109,140 cycles from the 2008-2010 SART registry, including 91,504 autologous cycles and 17,636 donor cycles in patients with non-tubal infertility. INTERVENTION(S): Varying amounts of oocytes retrieved in autologous and donor IVF. MAIN OUTCOME MEASURE(S): Ectopic pregnancy rates. RESULT(S): In autologous cycles, the EP rate significantly increased as oocyte yield increased. This association was not found in oocyte recipients. CONCLUSION(S): In autologous IVF cycles, increasing oocyte yield is correlated with a significantly increased EP rate. This association is not found in oocyte recipients, indicating that the increased EP rate may be due to the supraphysiologic hormone levels achieved with controlled ovarian hyperstimulation.
