RESUMO

BACKGROUND: Treatment exposures for childhood cancer reduce ovarian reserve. However, the success of assisted reproductive technology (ART) among female survivors is not well established. METHODS: Five-year survivors of childhood cancer in the Childhood Cancer Survivor Study were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, which captures national ART outcomes. The authors assessed the live birth rate, the relative risk (RR) with 95% confidence intervals (95% CIs), and associations with treatment exposure using generalized estimating equations to account for multiple ovarian stimulations per individual. Siblings from a random sample of survivors were recruited to serve as a comparison group. RESULTS: Among 9885 female survivors, 137 (1.4%; median age at diagnosis, 10 years [range, 0-20 years]; median years of follow-up after age 18 years, 11 years [range, 2-11 years]) underwent 224 ovarian stimulations using autologous or donor eggs and/or gestational carriers (157 autologous ovarian stimulation cycles, 67 donor ovarian stimulation cycles). In siblings, 33 (1.4%) underwent 51 autologous or donor ovarian stimulations. Of those who used embryos from autologous eggs without using gestational carriers, 97 survivors underwent 155 stimulations, resulting in 49 live births, for a 31.6% chance of live birth per ovarian stimulation (vs. 38.3% for siblings; p = .39) and a 43.9% chance of live birth per transfer (vs. 50.0%; p = .33). Prior treatment with cranial radiation therapy (RR, 0.44; 95% CI, 0.20-0.97) and pelvic radiation therapy (RR, 0.33; 95% CI, 0.15-0.73) resulted in a reduced chance of live birth compared with siblings. The likelihood of live birth after ART treatment in survivors was not affected by alkylator exposure (cyclophosphamide-equivalent dose, ≥8000 mg/m2 vs. none; RR, 1.04; 95% CI, 0.52-2.05). CONCLUSIONS: Childhood cancer survivors are as likely to undergo treatment using ART as sibling controls. The success of ART treatment was not reduced after alkylator exposure. The results from the current study provide needed guidance on the use of ART in this population.

RESUMO

BACKGROUND: Citing the risks of administering anesthesia to patients with obesity, few fertility centers offer in vitro fertilization as a treatment modality for patients with body mass indexes ≥40 kg/m2. Although previous studies have assessed clinical pregnancy and cumulative live birth rates in patients who spontaneously conceive with body mass indexes ≥50 kg/m2, there is a paucity of in vitro fertilization, obstetrical, and neonatal outcome data in patients with severe obesity who conceive after in vitro fertilization. OBJECTIVE: This study aimed to evaluate the impact of increasing body mass index on in vitro fertilization, obstetrical, and neonatal outcomes in patients with obesity undergoing in vitro fertilization. STUDY DESIGN: This was a retrospective cohort study within an academic fertility center including 2069 fresh in vitro fertilization/intracytoplasmic sperm injection and frozen embryo transfer cycles from January 1, 2012 to April 30, 2020; this cohort was used to determine in vitro fertilization treatment outcomes. A second embedded cohort of 867 fresh in vitro fertilization/intracytoplasmic sperm injection and frozen embryo transfer cycles that resulted in ongoing clinical pregnancies and deliveries within a single tertiary hospital system was used to determine pregnancy, maternal, and neonatal outcomes. All patients with a body mass index ≥40 kg/m2 underwent consultation with a maternal-fetal medicine specialist before starting treatment and a preoperative evaluation with an anesthesiologist before oocyte retrieval. Cycles were grouped by body mass index at cycle start (30-34.9, 35-39.9, 40-44.9, 45-49.9, and ≥50 kg/m2). Log-binomial regression and Poisson regression with an offset were fitted with body mass index of 30 to 34.9 kg/m2 as the reference group, adjusting for potential confounders including oocyte age, patient age, embryo quality, transfer type, and coexisting comorbidities. The primary outcome was live birth rate. Secondary outcomes included fertilization rate, blastulation rate, miscarriage rate, incidence of preeclampsia with severe features, gestational diabetes, labor induction, cesarean delivery, preterm delivery, and birthweight. RESULTS: There were 2069 fresh in vitro fertilization/intracytoplasmic sperm injection and frozen embryo transfer cycle starts from January 1, 2012 to April 30, 2020. Of these, 1008 cycles were in the 30 to 34.9 kg/m2 group, 547 in the 35 to 39.9 kg/m2 group, 277 in the 40 to 44.9 kg/m2 group, 161 in the 45 to 49.9 kg/m2 group, and 76 in the ≥50 kg/m2 body mass index group. Live birth rate was not significantly different between groups. The body mass index ≥50 kg/m2 group was significantly more likely to experience preeclampsia with severe features when compared with the 30 to 34.9 kg/m2 body mass index group (absolute risk reduction, 2.75; 95% confidence interval, 1.13-6.67). Fertilization rate, blastulation rate, miscarriage rate, incidence of gestational diabetes, labor induction, cesarean delivery, preterm delivery, and neonatal birthweights were not significantly different between groups. CONCLUSION: Among patients with body mass indexes from 30 to 60 kg/m2 who conceived via in vitro fertilization and received comprehensive prenatal care at a tertiary care hospital, in vitro fertilization, obstetrical, and neonatal outcomes were largely comparable. These data support a collaborative care approach with maternal-fetal medicine specialists and skilled anesthesiologists, reinforcing the notion that in vitro fertilization should not be withheld as a treatment modality from patients with obesity.

RESUMO

The use of preimplantation genetic testing for aneuploidy (PGT-A) in poor responders undergoing assisted reproductive technology has been a topic of debate with controversial results. It is critical to note the denominators used in data presented. Herein, we comment on the results found in the study by Kahraman et al. on the utility of PGT-A in poor responders with a single, good-quality blastocyst.

RESUMO

PURPOSE: The objective of this study was to assess if very-low-dose Lupron (VLDL) and ultra-low-dose Lupron (ULDL) protocols can have comparable cycle outcomes when compared to other "poor responder" stimulation protocols based on POSEIDON classification groups 3 (PG3) and 4 (PG4). METHODS: A retrospective cohort study at a single, large academic center was performed. Women in PG3 (age < 35, AMH < 1.2 ng/mL) or PG4 (age ≥ 35, AMH < 1.2 ng/mL) undergoing in vitro fertilization using an ULDL (Lupron 0.1 to 0.05 mg daily), VLDL (Lupron 0.2 to 0.1 mg daily), microflare (Lupron 0.05 mg twice a day), estradiol priming/antagonist, antagonist, or minimal stimulation protocols from 2012 to 2021 were included. The primary outcome was the number of mature oocytes (MII) obtained. The secondary outcome was live birth rate (LBR). RESULTS: The cohort included 3601 cycles. The mean age was 38.1 ± 3.8 years. In the PG3 group, ULDL and VLDL protocols produced a comparable number of MIIs (5.8 ± 4.3 and 5.9 ± 5.4, respectively) and live births (33.3% and 33.3%, respectively) when compared to other protocols. In the PG4 group, ULDL and VLDL protocols resulted in a higher percentage of MIIs when compared to microflare or minimal stimulation (Microflare/ULDL: adjusted relative risk (aRR) 0.78 (95% CI 0.65, 0.95); min stim/ULDL: aRR 0.47 (95% CI 0.38, 0.58); microflare/VLDL: aRR 0.77 (95% CI 0.63, 0.95); min stim/VLDL: aRR 0.47 (95% CI 0.38, 0.95)). There were no significant differences in LBR. CONCLUSION: Dilute Lupron downregulation protocols have comparable outcomes to other poor responder protocols and are reasonable to use.

RESUMO

BACKGROUND: A total of 19 states passed legislation mandating insurance coverage of assisted reproductive technology, and out-of-pocket costs associated with in vitro fertilization vary significantly depending on the region. Consequently, it has been observed that assisted reproductive technology utilization differs regionally and is associated with the presence of an insurance mandate. However, it is unknown whether regional differences exist among patients using donor oocytes. OBJECTIVE: This study aimed to determine the patient and cycle-specific parameters associated with the use of donor oocytes according to the insurance mandate status of the Society for Assisted Reproductive Technology clinic in which the assisted reproductive technology cycle was performed. STUDY DESIGN: This study was a retrospective cohort study using national data collected from the Society for Assisted Reproductive Technology registry for 39,338 donor oocyte cycles and 242,555 autologous oocyte cycles performed in the United States from January 1, 2014, to December 31, 2016. Cycles were stratified by insurance mandate of the state in which the assisted reproductive technology cycle was performed: comprehensive (coverage for at least 4 cycles of assisted reproductive technology), limited (coverage limited to 1-3 assisted reproductive technology cycles), offer (insurance mandates exist but exclude assisted reproductive technology treatment), and no mandate. The primary outcome was the number of previous autologous assisted reproductive technology cycles of the recipient. The secondary outcomes included age, serum follicle stimulating hormone level, frozen donor oocyte utilization, day of embryo transfer, number of embryos transferred, clinical pregnancy rate, and live birth rate. Analyses were adjusted for day of transfer, number of embryos transferred, and age of the recipient. RESULTS: Patients in no mandate states underwent fewer autologous assisted reproductive technology cycles (mean, 1.1; standard deviation, 1.6) before using donor oocytes than patients in offer (mean, 1.7; standard deviation, 2.5; P<.01), limited (mean, 1.5; standard deviation, 2.5; P<.01), and comprehensive (mean, 1.7; standard deviation, 2.0; P<.01) states. Patients in no mandate states were more likely to use frozen oocytes than patients in offer (relative risk, 0.54; 95% confidence interval, 0.52-0.57), limited (relative risk, 0.50; 95% confidence interval, 0.46-0.54), and comprehensive (relative risk, 0.94; 95% confidence interval, 0.89-0.99) states. Clinical pregnancy and live birth rates were similar among recipients of donor oocytes, regardless of insurance mandate. CONCLUSION: Despite similar ages and ovarian reserve parameters, patients without state-mandated insurance coverage of assisted reproductive technology were more likely to use frozen donor oocytes and undergo fewer autologous in vitro fertilization cycles than their counterparts in partial or comprehensive insurance coverage states. These differences in donor oocyte utilization highlight the financial barriers associated with pursuing assisted reproductive technology in uninsured states.

RESUMO

OBJECTIVE: The goal of preimplantation genetic testing for monogenic or single gene defects (PGT-M) is to identify inherited pathogenic variants in the embryo prior to embryo transfer, increasing the likelihood of an unaffected child. Prenatal diagnostic testing is recommended to confirm the results of PGT-M. The purpose of this study was to characterize the population undergoing PGT-M over time. METHODS: This retrospective study examined patients who had a positive pregnancy test after PGT-M from 2012 to 2019. A query of the internal assisted reproductive technology database and chart review were used. RESULTS: One hundred and 42 patients completed IVF cycles for PGT-M during this time period and progressed past 10 weeks gestation. There were more PGT-M cycles over time with 46 cycles between 2012 and 2015 and 96 cycles between 2016 and 2019. Patients varied on the decision to pursue prenatal diagnostic testing after PGT-M. For those with known follow-up (130/142), 16 patients underwent diagnostic testing (12%) and 114 did not. CONCLUSION: As PGT-M is increasingly utilized prior to pregnancy, it is important for genetic counselors and OB/GYNs to understand the characteristics and outcomes of the population of patients undergoing PGT-M, including how to counsel about the residual risk of an affected pregnancy after PGT-M.

RESUMO

BACKGROUND: Many young women with breast cancer undergo fertility preservation (FP) before cancer treatment. This study examined the impact of FP on breast cancer outcomes. METHODS: The authors performed a retrospective cohort study of 272 women aged 20 to 45 years with newly diagnosed stage 0 to III breast cancer who underwent an FP consultation between 2005 and 2017. Among these women, 123 (45.2%) underwent FP (fertility preservation-positive [FP+]). The remaining 149 women did not undergo FP (fertility preservation-negative [FP-]). RESULTS: The characteristics at enrollment were similar with the exception of ethnicity (FP+, 87.8% White; FP-, 67.8% White; P = .002) and BRCA status (FP+, 27.7% BRCA+; FP-, 15.5% BRCA+; P = .021). The median follow-up was approximately 4 years. Women who underwent FP had longer times to first treatment (FP+, 37 days; FP-, 31 days; adjusted hazard ratio [aHR], 0.74; confidence interval [CI], 0.56-0.99) and neoadjuvant chemotherapy (FP+, 36 days; FP-, 26 days; aHR, 0.41; CI, 0.24-0.68) and from surgery to adjuvant chemotherapy (FP+, 41 days; FP-, 33 days; aHR, 0.58; CI, 0.38-0.90). Adjusted 3- and 5-year invasive disease-free survival (IDFS) rates were comparable between the 2 groups (3-year IDFS: FP+, 85.4%; FP-, 79.4%; P = .411; 5-year IDFS: FP+, 73.7%; FP-, 67.1%; P = .288). Similarly, no difference in overall survival (OS) was observed between the 2 groups (3-year OS: FP+, 95.5%; FP-, 93.5%; P = .854; 5-year OS: FP+, 84.2%; FP-, 81.4%; P = .700). CONCLUSIONS: FP after a breast cancer diagnosis delays the time to treatment by a small amount, but this delay does not lead to inferior IDFS or OS.

RESUMO

STUDY QUESTION: Are embryos that fail to meet biopsy or freezing criteria on day 6 (D6) more likely to meet these criteria on day 7 (D7) if cultured in fresh medium from D6 to D7? SUMMARY ANSWER: Refreshment of medium on D6 did not increase the proportion of usable embryos on D7, with an adverse effect for women ≥40 years old. WHAT IS KNOWN ALREADY: Embryo development in continuous single-step medium, from fertilization to the blastocyst stage, is equivalent to that using a sequential media protocol. However, there remains a theoretical benefit of refreshing the culture environment by transitioning slowly developing D6 embryos to a fresh medium droplet of the same composition, with a renewed source of nutrients and a milieu free of metabolic toxins. STUDY DESIGN, SIZE, DURATION: This was a prospective trial of culture media exposure in which embryos were randomized on D6 to remain in the same culture medium from D3 to D7 (continuous, n = 620) or be moved to fresh medium (fresh, n = 603) on D6, with re-evaluation on D7. Data were collected from IVF cycles, with or without ICSI, between 29 March 2019 and 17 February 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS: Embryos from 298 women, aged 18-44 years, from cycles with or without preimplantation genetic testing (PGT) that did not meet criteria for biopsy and/or freeze on D6 were included in the study. Embryos were only included if there was a minimum of two embryos meeting the inclusion criteria in any cohort. Only the first cycle undertaken by each woman in the study period from which embryos were randomized was included. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1254 embryos were randomized from 312 cycles (209 non-PGT and 103 PGT) including 200 women undergoing IVF without PGT and 98 women who underwent PGT. The proportion of usable blastocysts on D7 did not differ between groups: 10.1% (61/603) in fresh versus 9.7% (60/620) in continuous medium (relative risk (RR) 1.05, 95% CI 0.74-1.47)). Embryos from women ≥40 years old had a significantly decreased likelihood of achieving a usable blastocyst on D7 after culture in fresh versus continuous medium: 3.5% versus 12.2%; RR 0.29, 95% CI 0.08-0.98. In total, 9.9% of embryos otherwise discarded on D6 met the criteria for biopsy and/or freeze on D7. LIMITATIONS, REASONS FOR CAUTION: Future work investigating implantation, clinical pregnancy and miscarriage rates with D7 embryos is still needed. WIDER IMPLICATIONS OF THE FINDINGS: Refreshment of medium on D6 did not increase the proportion of usable embryos on D7 overall. Younger women were more likely to develop D7 embryos after refreshment of medium on D6, while an adverse effect was seen in women ≥40 years old. However, by extending the culture of embryos to D7, additional blastocysts become available for clinical use.

RESUMO

BACKGROUND: A controversial and unresolved question in reproductive medicine is the utility of preimplantation genetic testing for aneuploidy as an adjunct to in vitro fertilization. Infertility is prevalent, but its treatment is notoriously expensive and typically not covered by insurance. Therefore, cost-effectiveness is critical to consider in this context. OBJECTIVE: This study aimed to analyze the cost-effectiveness of preimplantation genetic testing for aneuploidy for the treatment of infertility in the United States. STUDY DESIGN: As reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System, a national data registry, in vitro fertilization cycles occurring between 2014 and 2016 in the United States were analyzed. A probabilistic decision tree was developed using empirical outputs to simulate the events and outcomes associated with in vitro fertilization with and without preimplantation genetic testing for aneuploidy. The treatment strategies were (1) in vitro fertilization with intended preimplantation genetic testing for aneuploidy and (2) in vitro fertilization with transfers of untested embryos. Patients progressed through the treatment model until they achieved a live birth or 12 months after ovarian stimulation. Clinical costs related to both treatment strategies were extracted from the literature and considered from both the patient and payer perspectives. Outcome metrics included incremental cost (measured in 2018 US dollars), live birth outcomes, incremental cost-effectiveness ratio, and incremental cost per live birth between treatment strategies. RESULTS: The study population included 114,157 first fresh in vitro fertilization stimulations and 44,508 linked frozen embryo transfer cycles. Of the fresh stimulations, 16.2% intended preimplantation genetic testing for aneuploidy and 83.8% did not. In patients younger than 35 years old, preimplantation genetic testing for aneuploidy was associated with worse clinical outcomes and higher costs. At age 35 years and older, preimplantation genetic testing for aneuploidy led to more cumulative births but was associated with higher costs from both perspectives. From a patient perspective, the incremental cost per live birth favored the no preimplantation genetic testing for aneuploidy strategy from the <35 years age group to the 38 years age group and beginning at age 39 years favored preimplantation genetic testing for aneuploidy. From a payer perspective, the incremental cost per live birth favored preimplantation genetic testing for aneuploidy regardless of patient age. CONCLUSION: The cost-effectiveness of preimplantation genetic testing for aneuploidy is dependent on patient age and perspective. From an economic perspective, routine preimplantation genetic testing for aneuploidy should not be universally adopted; however, it may be cost-effective in certain scenarios.

RESUMO

IMPORTANCE: In in vitro fertilization cycles using autologous oocytes, data have demonstrated higher live birth rates following cryopreserved-thawed embryo transfers compared with fresh embryo transfers. It remains unknown if this association exists in cycles using freshly retrieved donor oocytes. OBJECTIVE: To test the hypothesis that in freshly retrieved donor oocyte cycles, a fresh embryo transfer is more likely to result in a live birth compared with a cryopreserved-thawed embryo transfer. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study using national data collected from the Society for Assisted Reproductive Technology for 33 863 recipients undergoing fresh donor oocyte cycles in the US between January 1, 2014 and December 31, 2017. EXPOSURES: Fresh embryo transfer and cryopreserved-thawed embryo transfer. MAIN OUTCOMES AND MEASURES: The primary outcome was live birth rate; secondary outcomes were clinical pregnancy rate and miscarriage rate. Analyses were adjusted for donor age, day of embryo transfer, use of a gestational carrier, and assisted hatching. RESULTS: Recipients of fresh and cryopreserved-thawed embryos had comparable median age (42.0 [interquartile range {IQR}, 37.0-44.0] years vs 42.0 [IQR, 36.0-45.0] years), gravidity (1 [IQR, 0-2] vs 1 [IQR, 0-3]), parity (0 [IQR, 0-1] vs 1 [IQR, 0-1]), and body mass index (24.5 [IQR, 21.9-28.7] vs 24.4 [IQR, 21.6-28.7]). Of a total of 33 863 recipients who underwent 51 942 fresh donor oocyte cycles, there were 15 308 (29.5%) fresh embryo transfer cycles and 36 634 (70.5%) cryopreserved-thawed embryo transfer cycles. Blastocysts were transferred in 92.4% of fresh embryo transfer cycles and 96.5% of cryopreserved-thawed embryo transfer cycles, with no significant difference in the mean number of embryos transferred. Live birth rate following fresh embryo transfer vs cryopreserved-thawed embryo transfer was 56.6% vs 44.0% (absolute difference, 12.6% [95% CI, 11.7%-13.5%]; adjusted relative risk [aRR], 1.42 [95% CI, 1.39-1.46]). Clinical pregnancy rates were 66.7% vs 54.2%, respectively (absolute difference, 12.5% [95% CI, 11.6%-13.4%]; aRR, 1.34; [95% CI, 1.31-1.37]). Miscarriage rates were 9.3% vs 9.4%, respectively (absolute difference, 0.2% [95% CI, -0.4% to 0.7%]); aRR, 0.98 [95% CI, 0.91-1.07]). CONCLUSIONS AND RELEVANCE: In this retrospective cohort study of women undergoing assisted reproduction using freshly retrieved donor oocytes, the use of fresh embryo transfers compared with cryopreserved-thawed embryo transfers was associated with a higher live birth rate. However, interpretation of the findings is limited by the potential for selection and confounding bias.

RESUMO

BACKGROUND: Hyperglycosylated human chorionic gonadotropin, the predominant human chorionic gonadotropin variant secreted following implantation, is associated with trophoblast invasion. OBJECTIVE: To determine whether the initial serum hyperglycosylated human chorionic gonadotropin differs between ongoing and failed pregnancies, and to compare it to total serum human chorionic gonadotropin as a predictor of ongoing pregnancy. MATERIALS AND METHODS: Women undergoing fresh/frozen in vitro fertilization cycles at a university-based infertility clinic with an autologous day 5 single embryo transfer resulting in serum human chorionic gonadotropin >3 mIU/mL (n = 115) were included. Human chorionic gonadotropin was measured 11 days after embryo transfer in a single laboratory (coefficient of variation <6%). Surplus frozen serum (-80oC) was shipped to Quest Laboratories for measurement of hyperglycosylated human chorionic gonadotropin (coefficient of variation <9.1%). Linear regression analyses adjusted for oocyte age a priori were used to compare human chorionic gonadotropin and hyperglycosylated human chorionic gonadotropin in ongoing pregnancies (>8 weeks of gestation) and failed pregnancies (clinical pregnancy loss, biochemical and ectopic pregnancies). RESULTS: A total of 85 pregnancies (73.9%) were ongoing. Hyperglycosylated human chorionic gonadotropin and human chorionic gonadotropin values were highly correlated (Pearson correlation coefficient 92.14, P < .0001), and mean values of both were positively correlated with blastocyst expansion score (P value test for trend < .0004). Mean human chorionic gonadotropin and hyperglycosylated human chorionic gonadotropin were significantly higher in ongoing vs failed pregnancies. Among ongoing pregnancies vs clinical losses, mean hyperglycosylated human chorionic gonadotropin, but not human chorionic gonadotropin, was significantly higher (19.0 vs 12.2 ng/mL, ß -8.1, 95% confidence interval -13.0 to -3.2), and hyperglycosylated human chorionic gonadotropin comprised a higher proportion of total human chorionic gonadotropin (4.6% vs 4.1%; risk ratio, 0.79; 95% confidence interval, 0.66-0.94). CONCLUSION: Measured 11 days after single blastocyst transfer, hyperglycosylated human chorionic gonadotropin and human chorionic gonadotropin values were highly correlated, but only mean hyperglycosylated human chorionic gonadotropin and its ratio to total human chorionic gonadotropin were significantly higher in ongoing pregnancies vs clinical pregnancy losses. Further evaluation of hyperglycosylated human chorionic gonadotropin, including in multiple embryo transfers and multiple pregnancy, and using serial measurements, is required.

RESUMO

PURPOSE: With advances in cancer therapy, reproductive-aged women can look forward to a life post-malignancy. Fortunately, fertility preservation (FP) may provide relief from potential infertility caused by cancer or associated caustic treatments. Outcomes of FP in pre-treatment reproductive-aged women with gliomas have not been previously characterized. METHODS: Between 2007 and 2018, 10 patients undergoing FP prior to chemotherapy and/or radiation treatment for gliomas were identified at Brigham and Women's Hospital. They were matched 3:1 to male-factor infertility patients by age ± 1 year. RESULTS: Patients with gliomas had significantly lower baseline anti-Müllerian hormone levels than male-factor infertility controls (2.37 vs 5.16 ng/mL, p = 0.002, log transformed). Despite higher starting (350 vs. 240 IU, p = 0.004) and total gonadotropin doses (4270 vs. 2270 IU, p < 0.001) over a similar stimulation duration (12.1 vs. 11.1 days, p = 0.219), cancer patients had lower peak estradiol levels (1420 vs. 2245 pg/mL, p = 0.003). The total number of follicles on the day of trigger (14.1 vs. 15.6, p = 0.284), the number of oocytes retrieved (18.4 vs. 20.5, p = 0.618), and the percentage of mature oocytes (69.9 vs. 73.8%, p = 0.076) were similar between cases and controls. One patient returned for a cryopreserved embryo transfer and delivered a healthy child. CONCLUSIONS: Patients undergoing FP prior to chemotherapy and/or radiation for a glioma achieve satisfactory FP outcomes and should be appropriately counseled regarding the opportunity to family-build after treatment.

RESUMO

PURPOSE: The purpose of this proof-of-concept study was to determine whether delta-9-tetrahydrocannabinol (THC) and THC metabolites (11-OH THC and THC-COOH) can be detected in semen. METHODS: Twelve healthy men aged 18-45 years who identified as chronic and heavy users of inhaled cannabis were recruited. THC and THC metabolite levels were measured in serum, urine, and semen of the participants. Semen analyses were performed. Serum reproductive hormones were measured. RESULTS: The median age and BMI of participants were 27.0 years and 24.7 kg/m2, respectively. Over half the participants were daily users of cannabis for over 5 years. Serum reproductive hormones were generally within normal ranges, except prolactin, which was elevated in 6 of 12 participants (mean 13.9 ng/mL). The median sperm concentration, motility, and morphology were 75.5 million/mL, 69.5%, and 5.5%, respectively. Urinary THC-COOH was detected in all 12 participants, and at least one serum THC metabolite was present in 10 of 12 participants. Two semen samples had insufficient volume to be analyzed. THC was above the reporting level of 0.50 ng/mL in the semen of two of the remaining participants. Seminal THC was moderately correlated with serum levels of THC (r = 0.66), serum 11-OH THC (r = 0.57), and serum THC-COOH (r = 0.67). Seminal delta-9 THC was not correlated with urinary cannabinoid levels or semen analysis parameters. CONCLUSION: This is the first study to identify and quantify THC in human semen, demonstrating that THC can cross the blood-testis barrier in certain individuals. Seminal THC was found to be moderately correlated with serum THC and THC metabolites.

RESUMO

BACKGROUND: It is critical to evaluate the combined impact of age and body mass index on the cumulative likelihood of live birth following in vitro fertilization, as achieving a lower body mass index before infertility treatment often is recommended for women with overweight and obesity. It is important to consider whether achieving a particular body mass index, thus resulting in an older age at in vitro fertilization cycle start, is beneficial or harmful to the likelihood of live birth. OBJECTIVES: To evaluate the combined impact of age and body mass index on the cumulative live birth rate following in vitro fertilization to inform when delaying in vitro fertilization treatment to achieve a lower body mass index may be beneficial or detrimental to the likelihood of live birth. STUDY DESIGN: This is a retrospective study using linked fresh and cryopreserved/frozen cycles from January 2014 to December 2015 from the Society for Reproductive Technology Clinic Outcome Reporting System, representing >90% of in vitro fertilization cycles performed in the United States. The primary outcome was live birth as measured by cumulative live birth rate. Secondary outcomes included implantation rate, clinical pregnancy rate, and miscarriage rate. Poisson and logistic regression were used to calculate risk and odds ratios with 95% confidence intervals to determine differences in implantation, clinical pregnancy, and miscarriage, as appropriate, among first fresh in vitro fertilization cycles compared across age (years) and body mass index (kg/m2) categories. Cox regression was used to calculate hazard ratios with 95% confidence intervals to determine differences in the cumulative live birth rate using fresh plus linked frozen embryo transfer cycles. RESULTS: There were 51,959 first fresh cycles using autologous eggs and 16,067 subsequent frozen embryo transfer cycles. There were 21,395 live births, for an overall cumulative live birth rate of 41.2% per cycle start. The implantation rate, clinical pregnancy rate, and cumulative live birth rate decreased with increasing body mass index and age, and the miscarriage rate increased with increasing body mass index and age (linear trend P<.001 for all). Body mass index had a greater influence on live birth at younger ages as compared with older ages. CONCLUSIONS: Age-related decline in fertility has a greater impact than body mass index on the cumulative live birth rate at older ages, suggesting that taking time to achieve lower body mass index before in vitro fertilization may be detrimental for older women with overweight or obesity. Delaying conception to lose weight before in vitro fertilization should be informed by the combination of age and body mass index.

RESUMO

STUDY OBJECTIVE: To evaluate the opinions and attitudes of the general public regarding uterine transplantation (UTx) in the United States. DESIGN: A cross-sectional study (Canadian Task Force classification II-2). SETTING: A Web-based survey. PATIENTS: A nationally representative sample of adult US residents by age and sex. INTERVENTIONS: A Web-based questionnaire administered in November 2016. MEASUREMENTS AND MAIN RESULTS: Respondents who supported UTx were compared with those who were opposed using log binomial regression to calculate relative risk ratios and 95% confidence intervals. Of the 1444 respondents recruited, 1337 (93%) completed the survey. Ninety respondents (6%) disagreed with the use of in vitro fertilization for any indication and were excluded. Of the remaining 1247 respondents, 977 (78%) supported and 48 (4%) opposed allowing women to undergo UTx. Respondents with higher yearly incomes and education level were more likely to agree that "taking the uterus from one person and putting it into another person is ethical." Respondents who answered that UTx is safe for the donor, recipient, and baby were more likely to believe that UTx is an acceptable, ethical alternative to a gestational carrier. Forty-five percent of respondents believed that UTx should be covered by insurance, whereas 24% did not. CONCLUSION: The majority of respondents in a sample of US residents support UTx, find it ethical, and believe that it is an acceptable alternative to a gestational carrier although support varies. These findings suggest that the US public is in favor of uterine transplantation as a treatment for uterine factor infertility.

RESUMO

OBJECTIVES: To evaluate and compare grading systems of subchorionic hematoma (SCH) on first-trimester ultrasound examinations with live embryos to assess which best correlates with early pregnancy outcome and to assess the effect of gestational age at the time of diagnosis on outcome. METHODS: First-trimester live singleton pregnancies between 6 and 11 weeks' gestational age with SCH were identified by an institutional database search. First-trimester outcome was categorized as "live" or "demise" based on ultrasound or medical record documentation. Hematomas were categorized in 4 ways: (1) subjective (small, moderate, or large); (2) subjective size based on fraction comparison with gestational sac size; (3) subjective grading based on the estimated percentage of the gestational sac surrounded by hematoma; and (4) 3 orthogonal measurements of the hematoma. RESULTS: A total of 434 sonograms met study inclusion criteria. The overall rate of first-trimester pregnancy failure was 12.0%. The rate of demise was significantly higher for hematomas diagnosed at or before 7 weeks (19.6%) than for those after 8 weeks (3.6%; P < .001). The size of the hematoma estimated as a fraction of gestational sac size significantly correlated with first-trimester pregnancy loss (P < .001). There was no statistical significance between first-trimester outcome and the other 2 subjective grading methods. Volume-based measurements provided spurious results because of the irregular shape of most hematomas. CONCLUSIONS: Subjective hematoma size based on the fraction of gestational sac size correlates best with first-trimester pregnancy outcome. The earlier in pregnancy an SCH is detected, the higher the rate of subsequent pregnancy failure.

RESUMO

PURPOSE: To determine the expected out-of-pocket costs of IVF with preimplantation genetic testing for aneuploidy (PGT-A) to attain a 50%, 75%, or 90% likelihood of a euploid blastocyst based on individual age and AMH, and develop a personalized counseling tool. METHODS: A cost analysis was performed and a counseling tool was developed using retrospective data from IVF cycles intended for PGT or blastocyst freeze-all between January 1, 2014 and August 31, 2017 (n = 330) and aggregate statistics on euploidy rates of > 149,000 embryos from CooperGenomics. Poisson regression was used to determine the number of biopsiable blastocysts obtained per cycle, based on age and AMH. The expected costs of attaining a 50%, 75%, and 90% likelihood of a euploid blastocyst were determined via 10,000 Monte Carlo simulations for each age and AMH combination, incorporating age-based euploidy rates and IVF/PGT-A cost assumptions. RESULTS: The cost to attain a 50% likelihood of a euploid blastocyst ranges from approximately $15,000 U.S. dollars (USD) for younger women with higher AMH values (≥ 2 ng/mL) to > $150,000 for the oldest women (44 years) with the lowest AMH values (< 0.1 ng/mL) in this cohort. The cost to attain a 75% versus 90% likelihood of a euploid blastocyst is similar (~ $16,000) for younger women with higher AMH values, but varies for the oldest women with low AMH values (~ $280,000 and > $450,000, respectively). A typical patient (36-37 years, AMH 2.5 ng/mL) should expect to spend ~ $30,000 for a 90% likelihood of attaining a euploid embryo. CONCLUSIONS: This tool can serve as a counseling adjunct by providing individualized cost information for patients regarding PGT-A.

RESUMO

The purpose of this article is to help the practitioner ensure early diagnosis and response to emergencies in the first trimester by reviewing anatomy of the developing embryo, highlighting the sonographic appearance of common first-trimester emergencies, and discussing key management pathways for treating emergent cases. First-trimester fetal development is a stepwise process that can be challenging to evaluate in the emergency department (ED) setting. This is due, in part, to the complex anatomy of early pregnancy, subtlety of the sonographic findings, and the fact that fewer than half of patients with ectopic pregnancy present with the classic clinical findings of a positive pregnancy test, vaginal bleeding, pelvic pain, and tender adnexa. Ultrasound (US) has been the primary approach to diagnostic imaging of first-trimester emergencies, with magnetic resonance imaging (MRI) and computed tomography (CT) playing a supportive role in a small minority of cases. Familiarity with the sonographic findings diagnostic of and suspicious for early pregnancy failure, ectopic pregnancy, retained products of conception, gestational trophoblastic disease, failed intrauterine devices, and complications associated with assisted reproductive technology (ART) is critical for any emergency radiologist. Evaluation of first-trimester emergencies is challenging, and knowledge of key imaging findings and familiarity with management pathways are needed to ensure early diagnosis and response.

RESUMO

Oncofertility is a unique, multidisciplinary field that serves to bridge the gap between available fertility resources and the special reproductive needs of cancer patients. Oncofertility is a growing field due to the increasing number of survivors, development of new oncologic therapies, extension of duration of therapies, and development and refinement of reproductive therapies. While the technologies and demand for services expand, clinicians need to be appropriately prepared for dealing with various clinical scenarios that may require ethical deliberation. Three real cases are presented in which the patient wishes to pursue reproductive assistance, but her decision is met with hesitance or uncertainty by her care team. Discussion of these clinical scenarios highlights ethical implications of oncofertility practice and serves to highlight the need for the establishment of multidisciplinary care teams and guidelines to support both clinicians and patients. IMPLICATIONS FOR PRACTICE: The growing field of oncofertility is ripe for conflict between patient autonomy and medical values due to the nature of cancer and associated threat on an individual's health and survival, as well as the personal significance of childbearing. Cases are presented and ethical implications are discussed to further explore the inherent difficulties in oncofertility practice and guide clinicians in similar situations. Developing guidelines and establishing multidisciplinary teams to facilitate oncofertility discussions and care, as well as training of clinical team members, may improve patient safety, well-being, and satisfaction within the context of fertility decision making, care, and outcomes.

RESUMO

STUDY QUESTION: Compared to D5 selection with conventional morphology (CM), does adjunctive use of the Eeva™ test on D3 or D5 improve the clinical pregnancy rate (CPR) per transfer? SUMMARY ANSWER: The evidence is insufficient to conclude that adjunctive use of the Eeva™ test on D3 or D5 improves CPR per transfer as compared to D5 selection with CM. WHAT IS KNOWN ALREADY: Time-lapse imaging is increasingly used for embryo selection, despite there being no class I data to support its clinical application. STUDY DESIGN, SIZE, DURATION: Pilot randomized controlled trial included 163 patients from August 2014 to February 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients up to age 41 years with a planned fresh autologous single embryo transfer (SET), less than four prior oocyte retrievals, and four or more zygotes were blocked according to age (<35, 35-37, 38-40 years) and randomized to one of three study arms: (1) D3 SET + EevaTM, (2) D5 SET + Eeva™ or (3) D5 SET with CM alone. All embryos were cultured in the same time-lapse system under identical conditions. Intention-to-treat (ITT) and as-treated analyses of the primary endpoint (CPR at 7 weeks) and secondary endpoint (ongoing pregnancy rate at 12 weeks) were performed. Multivariate regression analyses adjusted for patient age and ICSI. MAIN RESULTS AND THE ROLE OF CHANCE: Of 478 eligible patients, 217 consented and 163 were randomized. Demographic characteristics were similar among the three study arms. There were no statistically significant differences in the clinical pregnancy rate or the ongoing pregnancy rate between the study arms for either the ITT or as-treated analyses (CPR ITT: D3 + Eeva™: 41.1% vs. D5 + Eeva™: 38.9% vs. D5 CM: 49.1%). LIMITATIONS, REASONS FOR CAUTION: This study was designed as a pilot randomized controlled trial and was not powered to detect a statistically significant difference at α < 0.05. Importantly, the study was terminated prematurely by the sponsor due to a change in funding priorities, so the sample size is limited and the results should be interpreted with caution due to the role of chance. Furthermore, these findings may not be generalizable to other time-lapse systems. WIDER IMPLICATIONS OF THE FINDINGS: Our findings do not support the clinical application of these time-lapse markers. STUDY FUNDING/COMPETING INTEREST(S): This study was funded by Progyny, Inc. There are no competing interests. TRIAL REGISTRATION NUMBER: clinicaltrials.gov: NCT02218255. TRIAL REGISTRATION DATE: 14 August 2014. DATE OF FIRST PATIENT'S ENROLLMENT: 3 September 2014.
