ABSTRACT

OBJECTIVE: To assess the effects of demographic shifts, changes in contemporaneous clinical practices, and technologic innovation on assisted reproductive technology (ART) success rates by conducting an analysis of cumulative live-birth rates across different time periods, age groups, and infertility diagnoses. METHODS: We conducted a retrospective cohort study of autologous linked cycles comparing cumulative live-birth rates over successive cycles from patients undergoing their first retrieval between 2014 and 2019 in the SART CORS (Society for Assisted Reproductive Technology Clinic Outcome Reporting System) database. All cycles reported for these individuals up to 2020 were included for analysis. We compared cumulative live-birth rates stratified by age and infertility cause with published data from the 2004-2009 SART CORS database. RESULTS: From 2014 to 2019, 447,042 patients underwent their first autologous index retrieval, resulting in 1,007,374 cycles and 252,215 live births over the period of 2014 to 2020. In contrast, between 2004 and 2008, 246,740 patients underwent 471,208 cycles, resulting in 140,859 births by 2009. Noteworthy shifts in demographics were observed, with an increase in people of color seeking reproductive technology (57.9% vs 51.7%, P <.001). There was also an increase in patients with diminished ovarian reserve and ovulatory disorders and a decrease in endometriosis, tubal, and male factor infertility ( P <.001). Previously associated with decreased odds of live birth, frozen embryo transfer and preimplantation genetic testing showed increased odds in 2014-2020. Preimplantation genetic testing rose from 3.4% to 36.0% and was associated with a lower cumulative live-birth rate for those younger than age 35 years ( P <.001) but a higher cumulative live-birth rate for those aged 35 years or older ( P <.001). Comparing 2014-2020 with 2004-2009 shows that the overall cumulative live-birth rate improved for patients aged 35 years or older and for all infertility diagnoses except ovulatory disorders ( P <.001). CONCLUSION: This analysis provides insights into the changing landscape of ART treatments in the United States over the past two decades. The observed shifts in demographics, clinical practices, and technology highlight the dynamic nature of an evolving field of reproductive medicine. These findings may offer insight for clinicians to consider in counseling patients and to inform future research endeavors in the field of ART.

ABSTRACT

Importance: Cancer is a leading cause of death among children worldwide. Treatments used for medically assisted reproduction (MAR) are suspected risk factors because of their potential for epigenetic disturbance and associated congenital malformations. Objective: To assess the risk of cancer, overall and by cancer type, among children born after MAR compared with children conceived naturally. Design, Setting, and Participants: For this cohort study, the French National Mother-Child Register (EPI-MERES) was searched for all live births that occurred in France between January 1, 2010, and December 31, 2021 (and followed up until June 30, 2022). The EPI-MERES was built from comprehensive data of the French National Health Data System. Data analysis was performed from December 1, 2021, to June 30, 2023. Exposure: Use of assisted reproduction technologies (ART), such as fresh embryo transfer (ET) or frozen ET (FET), and artificial insemination (AI). Main Outcomes and Measures: The risk of cancer was compared, overall and by cancer type, among children born after fresh ET, FET, or AI and children conceived naturally, using Cox proportional hazards regression models adjusted for maternal and child characteristics at birth. Results: This study included 8 526 306 children with a mean (SD) age of 6.4 (3.4) years; 51.2% were boys, 96.4% were singletons, 12.1% were small for gestational age at birth, and 3.1% had a congenital malformation. There were 260 236 children (3.1%) born after MAR, including 133 965 (1.6%) after fresh ET, 66 165 (0.8%) after FET, and 60 106 (0.7%) after AI. A total of 9256 case patients with cancer were identified over a median follow-up of 6.7 (IQR, 3.7-9.6) years; 165, 57, and 70 were born after fresh ET, FET, and AI, respectively. The overall risk of cancer did not differ between children conceived naturally and those born after fresh ET (hazard ratio [HR], 1.12 [95% CI, 0.96 to 1.31]), FET (HR, 1.02 [95% CI, 0.78 to 1.32]), or AI (HR, 1.09 [95% CI, 0.86 to 1.38]). However, the risk of acute lymphoblastic leukemia was higher among children born after FET (20 case patients; HR 1.61 [95% CI, 1.04 to 2.50]; risk difference [RD], 23.2 [95% CI, 1.5 to 57.0] per million person-years) compared with children conceived naturally. Moreover, among children born between 2010 and 2015, the risk of leukemia was higher among children born after fresh ET (45 case patients; HR, 1.42 [95% CI, 1.06 to 1.92]; adjusted RD, 19.7 [95% CI, 2.8 to 43.2] per million person-years). Conclusions and Relevance: The findings of this cohort study suggest that children born after FET or fresh ET had an increased risk of leukemia compared with children conceived naturally. This risk, although resulting in a limited number of cases, needs to be monitored in view of the continuous increase in the use of ART.

ABSTRACT

OBJECTIVE: To evaluate monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin pregnancies conceived by assisted reproductive technology (ART) and conceived naturally. METHODS: We retrospectively analyzed the data on twin pregnancies conceived by ART from January 2015 to January 2022,and compared pregnancy outcomes of MCDA and DCDA twins conceived by ART with those of MCDA and DCDA twins conceived naturally, pregnancy outcomes between MCDA and DCDA twins conceived by ART, and pregnancy outcomes of DCT and TCT pregnancies reduced to DCDA pregnancies with those of DCDA pregnancies conceived naturally. RESULT: MCDA pregnancies conceived by ART accounted for 4.21% of the total pregnancies conceived by ART and 43.81% of the total MCDA pregnancies. DCDA pregnancies conceived by ART accounted for 95.79% of the total pregnancies conceived by ART and 93.26% of the total DCDA pregnancies. Women with MCDA pregnancies conceived by ART had a higher premature delivery rate, lower neonatal weights, a higher placenta previa rate, and a lower twin survival rate than those with MCDA pregnancies conceived naturally (all p < 0.05). Women with DCDA pregnancies conceived naturally had lower rates of preterm birth, higher neonatal weights, and higher twin survival rates than women with DCDA pregnancies conceived by ART and those with DCT and TCT pregnancies reduced to DCDA pregnancies (all p < 0.05). CONCLUSION: Our study confirms that the pregnancy outcomes of MCDA pregnancies conceived by ART are worse than those of MCDA pregnancies conceived naturally. Similarly, the pregnancy outcomes of naturally-conceived DCDA pregnancies are better than those of DCDA pregnancies conceived by ART and DCT and TCT pregnancies reduced to DCDA pregnancies.

ABSTRACT

OBJECTIVE: To assess the effect of geographic factors on fertility-sparing treatment or assisted reproductive technology (ART) utilization among women with gynecologic or breast cancers. METHODS: We conducted a cohort study of reproductive-aged patients (18-45 years) with early-stage cervical, endometrial, or ovarian cancer or stage I-III breast cancer diagnosed between January 2000 and December 2015 using linked data from the California Cancer Registry, the California Office of Statewide Health Planning and Development, and the Society for Assisted Reproductive Technology. Generalized linear mixed models were used to evaluate associations between distance from fertility and gynecologic oncology clinics, as well as California Healthy Places Index score (a Census-level composite community health score), and ART or fertility-sparing treatment receipt. RESULTS: We identified 7,612 women with gynecologic cancer and 35,992 women with breast cancer. Among all patients, 257 (0.6%) underwent ART. Among patients with gynecologic cancer, 1,676 (22.0%) underwent fertility-sparing treatment. Stratified by quartiles, residents who lived at increasing distances from gynecologic oncology or fertility clinics had decreased odds of undergoing fertility-sparing treatment (gynecologic oncology clinics: Q2, odds ratio [OR] 0.76, 95% CI, 0.63-0.93, P =.007; Q4, OR 0.72, 95% CI, 0.56-0.94, P =.016) (fertility clinics: Q3, OR 0.79, 95% CI, 0.65-0.97, P =.025; Q4, OR 0.67, 95% CI, 0.52-0.88, P =.004), whereas this relationship was not observed among women who resided within other quartiles (gynecologic oncology clinics: Q3, OR 0.81 95% CI, 0.65-1.01, P =.07; fertility clinics: Q2, OR 0.87 95% CI, 0.73-1.05, P =.15). Individuals who lived in communities with the highest (51 st -100 th percentile) California Healthy Places Index scores had greater odds of undergoing fertility-sparing treatment (OR 1.29, 95% CI, 1.06-1.57, P =.01; OR 1.66, 95% CI, 1.35-2.04, P =.001, respectively). The relationship between California Healthy Places Index scores and ART was even more pronounced (Q2 OR 1.9, 95% CI, 0.99-3.64, P =.05; Q3 OR 2.86, 95% CI, 1.54-5.33, P <.001; Q4 OR 3.41, 95% CI, 1.83-6.35, P <.001). CONCLUSION: Geographic disparities affect fertility-sparing treatment and ART rates among women with gynecologic or breast cancer. By acknowledging geographic factors, health care systems can ensure equitable access to fertility-preservation services.

ABSTRACT

BACKGROUND: Orthopedic surgery continues to have one of the lowest rates of female trainees among all medical specialties in the United States. Barriers to pursuing a surgical residency include the challenges of family planning and work-life balance during training. METHODS: A systematic literature search of articles published between June 2012 and December 2022 in the MEDLINE, EMBASE, and Cochrane databases was performed in January 2023 according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Studies were included if they evaluated pregnancy and peripartum experience and/or outcomes amongst orthopedic surgeons or trainees. RESULTS: Eighteen studies were included. Up to 67.3% of female orthopedic surgeons and trainees and 38.7% of their male counterparts delayed childbearing during residency. The most reported reasons for this delay included career choice as an orthopedic surgeon, residency training, and reputational concerns among faculty or co-residents. Infertility ranged from 17.0% to 30.4% in female orthopedic surgeons and up to 31.2% suffered obstetric complications. Assisted Reproductive Technology (ART) resulted in 12.4%-56.3% of successful pregnancies. Maternity and paternity leaves ranged from 1 to 11 weeks for trainees with more negative attitudes associated with maternal leave. CONCLUSIONS: Female orthopedic trainees and attending delay childbearing, experience higher rates of obstetric complications, and more stigma associated with pregnancy compared to their male colleagues. Program and institutional policies regarding maternity and paternity leave are variable across programs, and therefore, attention should be directed toward standardizing policies.

ABSTRACT

Importance: A publicly funded fertility program was introduced in Ontario, Canada, in 2015 to increase access to fertility treatment. For in vitro fertilization (IVF), the program mandated an elective single-embryo transfer (eSET) policy. However, ovulation induction and intrauterine insemination (OI/IUI)-2 other common forms of fertility treatment-were more difficult to regulate in this manner. Furthermore, prior epidemiologic studies only assessed fetuses at birth and did not account for potential fetal reductions that may have been performed earlier in pregnancy. Objective: To examine the association between fertility treatment and the risk of multifetal pregnancy in a publicly funded fertility program, accounting for both fetal reductions and all live births and stillbirths. Design, Setting, and Participants: This population-based, retrospective cohort study used linked administrative health databases at ICES to examine all births and fetal reductions in Ontario, Canada, from April 1, 2006, to March 31, 2021. Exposure: Mode of conception: (1) unassisted conception, (2) OI/IUI, or (3) IVF. Main Outcomes and Measures: The main outcome was multifetal pregnancy (ie, a twin or higher-order pregnancy). Modified Poisson regression generated adjusted relative risks (ARRs) and derived population attributable fractions (PAFs) for multifetal pregnancies attributable to fertility treatment. Absolute rate differences (ARDs) were used to compare the era before eSET was promoted (2006-2011) with the era after the introduction of the eSET mandate (2016-2021). Results: Of all 1 724 899 pregnancies, 1 670 825 (96.9%) were by unassisted conception (mean [SD] maternal age, 30.6 [5.2] years), 24 395 (1.4%) by OI/IUI (mean [SD] maternal age, 33.1 [4.4] years), and 29 679 (1.7%) by IVF (mean [SD] maternal age, 35.8 [4.7] years). In contrast to unassisted conception, individuals who received OI/IUI or IVF tended to be older, reside in a high-income quintile neighborhood, or have preexisting health conditions. Multifetal pregnancy rates were 1.4% (95% CI, 1.4%-1.4%) for unassisted conception, 10.5% (95% CI, 10.2%-10.9%) after OI/IUI, and 15.5% (95% CI, 15.1%-15.9%) after IVF. Compared with unassisted conception, the ARR of any multifetal pregnancy was 7.0 (95% CI, 6.7-7.3) after OI/IUI and 9.9 (95% CI, 9.6-10.3) after IVF, with corresponding PAFs of 7.1% (95% CI, 7.1%-7.2%) and 13.4% (95% CI, 13.3%-13.4%). Between the eras of 2006 to 2011 and 2016 to 2021, multifetal pregnancy rates decreased from 12.9% to 9.1% with OI/IUI (ARD, -3.8%; 95% CI, -4.2% to -3.4%) and from 29.4% to 7.1% with IVF (ARD, -22.3%; 95% CI, -23.2% to -21.6%). Conclusions and Relevance: In this cohort study of more than 1.7 million pregnancies in Ontario, Canada, a publicly funded IVF program mandating an eSET policy was associated with a reduction in multifetal pregnancy rates. Nevertheless, ongoing strategies are needed to decrease multifetal pregnancy, especially in those undergoing OI/IUI.

ABSTRACT

BACKGROUND: Assisted reproductive technologies (ARTs) have become the main treatment for infertility. ART treatment can be a stressful life event for infertile females. Whether there is an association between ARTs and postpartum depressive symptoms (PDS) has not been established. METHODS: PubMed, MEDLINE, EMBASE, PsycINFO, and CNKI were searched. The pooled outcome was the difference in incidence of PDS within 1 year postpartum between ARTs and the spontaneous pregnancy group. RESULTS: A total of 12 cohort studies, which were conducted in eight developed countries and two developing countries, were involved. In total, 106,338 pregnant women, including 4990 infertile females with ARTs treatment and 101,348 women with spontaneous pregnancy, were enrolled in our final analysis. ARTs women had a lower incidence of PDS compared to the spontaneous pregnancy group according to a random effect model (OR = 0.83, 95 % CI: 0.71-0.97, p = 0.022, I2 = 62.0 %). Subgroup analyses indicated that studies on late PDS (follow-up: 3-12 months postpartum) were more heterogeneous than those on early PDS (follow-up: <3 months postpartum) (I2 = 24.3 % vs. I2 = 0 %, interaction p-value < 0.001). There was a strong relationship between ARTs and late PDS (OR = 0.65, 95 % CI: 0.55-0.77, p < 0.001). Therefore, the possible source of heterogeneity was the postpartum evaluation time, which was confirmed by post-hoc meta-regression. LIMITATIONS: Some underlying confounders, such as previous psychiatric illness, the limited availability of ARTs, and ethnic disparities, cannot be ignored and may have biased interpretation of the results. CONCLUSION: The available data suggested that ARTs were associated with lower incidence of PDS, especially when follow-up lasted over 3 months. However, these findings should be interpreted with caution. Better-designed trials are needed to confirm this association.

ABSTRACT

Researchers interested in causal questions must deal with two sources of error: random error (random deviation from the true mean value of a distribution), and bias (systematic deviance from the true mean value due to extraneous factors). For some causal questions, randomization is not feasible, and observational studies are necessary. Bias poses a substantial threat to the validity of observational research and can have important consequences for health policy developed from the findings. The current piece describes bias and its sources, outlines proposed methods to estimate its impacts in an observational study, and demonstrates how these methods may be used to inform debate on the causal relationship between medically assisted reproduction (MAR) and health outcomes, using cancer as an example. In doing so, we aim to enlighten researchers who work with observational data, especially regarding the health effects of MAR and infertility, on the pitfalls of bias, and how to address them. We hope that, in combination with the provided example, we can convince readers that estimating the impact of bias in causal epidemiologic research is not only important but necessary to inform the development of robust health policy and clinical practice recommendations.

ABSTRACT

OBJECTIVE: This research was conducted to assess access to assisted reproductive technologies (ART) and the current status of the in vitro fertilization (IVF) program that have been implemented in Indonesia over the last 10 years. METHODS: We established a retrospective cohort study and descriptive analysis of the current state of access to infertility care in Indonesia. The data were collected from all IVF centers, clinics, and hospitals in Indonesia from 2011 to 2020, including the number of IVF clinics, total ART cycles, retrieved fresh and frozen embryos, average age of IVF patients, IVF pregnancy rate, and causes of infertility. RESULTS: The number of reported fertility clinics in Indonesia has increased from 14 clinics in 2011 to 41 clinics by 2020. As many as 69 569 ART cycles were conducted over the past 10 years, of which 51 892 cycles used fresh embryos and 17 677 cycles used frozen embryos. The leading cause of consecutive infertility diagnosis was male infertility. Nearly half of the women who underwent IVF procedures (48.9%) were under 35 years old. The pregnancy rate outcome of women who underwent IVF ranged from 24.6% to 37.3%. CONCLUSION: Developments in ART in Indonesia have led to improvements in the ART cycles performed throughout the 10 year period. The identification of key areas that require improvement can provide an opportunity to enhance access to infertility care.

ABSTRACT

Infertility disproportionately affects the minority, non-White populace, with Black women having twofold higher odds than White women. Despite higher infertility rates, minority racial and ethnic groups access and utilize fertility care less frequently. Even once care is accessed, racial and ethnic disparities exist in infertility treatment and ART outcomes. Preliminary studies indicate that Asian and American Indian women have lower intrauterine insemination pregnancy rates. Many robust studies indicate significant racial and ethnic disparities in rates of clinical pregnancy, live birth, pregnancy loss, and obstetrical complications following in vitro fertilization, with lower favorable outcomes in Black, Asian, and Hispanic women.

ABSTRACT

OBJECTIVE: The COVID-19 pandemic has been the most serious public health emergency encountered in modern assisted reproductive technology (ART) development. In order to identify lessons learned, this study reviews the effect of the pandemic on ART institutions and human sperm banks in China, and summarizes the experiences and reflections of Chinese scholars post-pandemic era. METHODS: This review is based on multiple consensus statements on the COVID-19 pandemic issued by Chinese experts as well as current national regulations and principles in ART institutions and human sperm banks to document the current situation of ART services in China, describe the impact of the pandemic on these services, and offer Chinese reflections on worrying issues in the post-pandemic era. RESULTS: China reached one million ART cycles in 2016, and there are currently 540 ART medical institutions and 27 human sperm banks, with 540 licensed for AIH, 91 for AID, 415 for conventional IVF and ICSI and 85 for PGT. Of these, only 4 institutions carry out 10,000 cycles or more annually, and the proportion of institutions with less than 1,000 cycles has reached 66%, which means that a considerable number of ART institutions are still not saturated. As a consequence of the COVID-19 pandemic, 63.6% of ART providers and 95.5% of human sperm banks suspended operations. By the end of May 2020, China, as an early country affected by the pandemic achieved a national resumption rate of ART medical services of 99.2% and that of human sperm banks of 100.0%. Reports from the first and largest human sperm bank in China showed that qualification, semen concentration and sperm viability rates measured at primary screening have significantly decreased post-pandemic. Much like in other countries, Chinese experts developed a consensus on prevention and control measures during the pandemic. In principle, all ART activities should be suspended during acute phases of infection spread. Chinese scholars highlight that attention should be paid to young patients with fertility requirements during and after COVID-19, and emphasize the importance of fertility evaluation and clinical intervention. In addition, couples should be reminded that during ART treatment, disinfectants should not be used excessively to minimize risks of damaging the reproductive system, gametes and zygotes. At the same time, timely and reasonable guidance for tackling negative emotions from stress response is needed to provide reassurance and to avoid irrational fear and excessive stress. Seminal parameters should be re-examined 2 months after SARS-CoV-2 vaccination, and ART treatments recommenced if no abnormalities are detected. CONCLUSIONS: Given the growing frequency of outbreaks of global infectious diseases in recent years, ART institutions and human sperm banks should pay attention to improving their prevention and control capabilities. To a certain extent, decisions and measures adopted in China during COVID-19 pandemic are worthy of recognition and acceptance. Chinese scholars have discussed, proactively responded to and understand the key issues surrounding ART development during the pandemic with the aim of contributing to the substantial progress and healthy development of ART services in the world.

ABSTRACT

AIM: From April 2022, the Japanese government funding system for assisted reproductive technology (ART) has shifted from government subsidies to universal health insurance. To date, studies estimating the health care expenditure for ART are scarce. We estimated health care expenditures for ART cycles and compared the proportion of patients' out-of-pocket payment by ovarian stimulation protocols under the Japanese government subsidy system. METHODS: We linked payment information for government subsidies in Saitama Prefecture during 2016 and 2017 with the Japanese ART registry. Health care expenditures for all treatment cycles in Japan during 2017 among women aged <43 years (n = 369 757) were estimated using a generalized linear model. RESULTS: We linked 6269 subsidy applications to the Japanese ART registry. The average treatment fee for a fresh cycle was 376 434 JPY (standard deviation = 159 581). However, significant variation was observed across ovarian stimulation protocols. The estimated health care expenditure for ART during 2017 was 101 278 629 888 JPY (920 714 817 USD), leading to a 0.24% increase in the national health care expenditure for fiscal year 2017. Fresh cycles accounted for 70% of the expenditure. The proportion of the average patient out-of-pocket payment for one treatment cycle was smaller for natural (0%) and mild ovarian stimulation using clomiphene citrate (4.5%-20.7%) than those of conventional stimulation (30.3%-32.4%). CONCLUSIONS: Health insurance coverage for ART would increase national health care expenditure by 0.24%. Under the subsidy system, the proportion of the average patient out-of-pocket payment was smaller for natural and mild ovarian stimulation than conventional stimulations.

ABSTRACT

BACKGROUND: Within-sibship analyses show lower perinatal mortality after assisted reproductive technology (ART) compared with natural conception (NC), a finding that appears biologically unlikely. We investigated whether this may be attributed to bias from selective fertility and carryover effects. METHODS: Using data from national registries in Denmark (1994-2014), Finland (1990-2014) and Norway and Sweden (1988-2015), we studied 5 722 826 singleton pregnancies, including 119 900 ART-conceived and 37 590 exposure-discordant sibships. Perinatal mortality at the population level and within sibships was compared using multilevel logistic regression with random and fixed intercepts, respectively. We estimated selective fertility as the proportion of primiparous women with and without perinatal loss who had a second delivery, and carryover effects through bidirectional and crosswise associations. RESULTS: Population analysis showed higher perinatal mortality among ART conception compared with NC (odds ratio 1.21, 95% CI 1.13 to 1.30), whereas within-sibship analysis showed the opposite (OR 0.36, 95% CI 0.31 to 0.43). Primiparous women with perinatal loss were more likely to give birth again (selective fertility) and to use ART in this subsequent pregnancy (carryover effects), resulting in strong selection of double-discordant sibships with death of the naturally conceived and survival of the ART-conceived sibling. After controlling for conception method and outcome in the first pregnancy, ART was not consistently associated with perinatal mortality in the second pregnancy. CONCLUSIONS: Whereas population estimates may be biased by residual confounding, within-sibship estimates were biased by selective fertility and carryover effects. It remains unclear whether ART conception contributes to perinatal mortality.

ABSTRACT

Background Infertility and its treatment are frequently associated with psychological distress. We assessed the prevalence of anxiety and depression in couples undergoing treatment for infertility with assisted reproductive techniques (ARTs). Methods We included 160 married couples undergoing treatment for infertility at an ART centre. The prevalence of anxiety and depression was assessed using the hospital anxiety and depression scale. Results The prevalence of anxiety and depression was 46.2% and 40.9%, respectively. Women had higher mean (SD) anxiety (10.76 [2.69]) and depression (9.86 [2.06]) scores; however, this gender difference was statistically significant only with respect to anxiety (p=0.02). The mean anxiety scores were highest among both genders when the cause of infertility was attributed to both partners and during the first year and 10 years after treatment. Men in the age groups of 20-24 years and 40-44 years and those with no prior treatment had a statistically significant association with the highest anxiety scores. The mean depression scores showed a statistically significant decline in both genders with increasing age. Among men, the mean depression scoreswere significantly higher in those with no prior treatment, male cause of infertility and during the first year and after 10 years of treatment. Conclusion The prevalence of anxiety and depression among infertile couples undergoing treatment with ART was almost twice as high as that in the general population. The mean anxiety scores were significantly associated with duration of treatment and gender-based attribution in both genders; however, age and prior treatment were associated with only men. The mean scores of depression were significantly associated with age in both genders, while duration of treatment, gender-based attribution and prior treatment were significantly associated only with men.

ABSTRACT

PURPOSE: Assisted reproduction technologies (ART) are associated with increased risks of pregnancy complications and obstetric interventions. Here, we aimed to determine if ART affects placental inflammation and oxidative stress as a mechanism for unfavorable pregnancy outcomes. METHODS: The levels of six cytokines (IFN-γ, IL-1ß, IL-6, IL-8, IL-10, TNFα) were measured using multiplex ELISA. The activity of four antioxidant enzymes (glutathione S-transferase (GST), glutathione peroxidase (GPx), glutathione reductase, superoxide dismutase) and levels of two antioxidants (GSH, vitamin E) were measured using commercial/in-house assays. Markers were compared between ART and unassisted pregnancies, and then groups were stratified using ICD9/10 codes to determine differences in specific clinical contexts. RESULTS: In unassisted twin pregnancies, there was a trend of decreased cytokine levels (IL-1ß, IL-6, IL-8, TNFα, p < 0.05), but cytokines in ART twins were the same or higher. Additionally, GST and GPx activities were lower in unassisted twins, and vitamin E levels were higher in ART twins (p < 0.05). In pregnancies complicated by chorioamnionitis, there was a trend of increased cytokine levels in unassisted pregnancies (IL-1ß, IL-6, and IL-8, p < 0.05). No increase was observed in ART, and IFN-γ and TNFα were decreased (p < 0.05). Placental GST and GPx activities were higher in unassisted pregnancies with chorioamnionitis compared to ART (p < 0.05). CONCLUSION: Attenuation of protective placental inflammatory and oxidative stress responses may play a role in the underlying pathogenesis of negative birth outcomes in ART, expanding our understanding of adverse pregnancy outcomes when ART is used to conceive.

ABSTRACT

Hispanic women have lower rates of use of infertility services than non-Hispanic White women. There are many barriers that impede access to infertility care including economic, geographic, cultural, and societal factors and there are disparities in treatment outcomes. Hispanic women are less likely to seek infertility care than non-Hispanic White women and even after infertility evaluation, Hispanic women are less likely to receive treatment for their infertility. Lower use of infertility treatments among Hispanic women is unlikely to be driven solely by economic factors. There is disappointingly little data on in-vitro fertilization treatment outcomes including the population of Hispanic women, and existing data has yielded conflicting results. Incomplete and variable reporting of race data across clinics raises the potential for misclassification bias and invalid study conclusions. Addressing disparities in access to reproductive medicine in the Hispanic population will required a multifaceted approach including expanded insurance coverage, improved education for both patients and providers, and additional research on barriers to care.

ABSTRACT

OBJECTIVE: Although there has been increased utilization of assisted reproductive technologies (ART) in the world, there is no conclusive definition about the relationship between the success rate of ART and national wealth. METHODS: In this study, using the data from the International Committee for Monitoring Assisted Reproductive Technologies (ICMART), we sought to determine whether there is a correlation between the success rate of ART (represented by pregnancy and delivery rates) and national wealth represented by the gross domestic product (GDP) per capita. Moreover, to further understand the effect of GDP per capita on ART effectiveness, we analyzed the association between ART success rate and GDP per capita in 50 US states. RESULTS: Our data showed that the number of ART treatment cycles increased as the GDP per capita increased. However, we found a negative correlation between ART success rates and GDP per capita in ICMART countries, although no correlation was seen in the US states. Using rough estimation, we derived that the success rate of ART was not related to GDP per capita in the ICMART countries with a GDP per capita greater than USD 13,000. CONCLUSIONS: In conclusion, for the first time, we showed that when the GDP per capita of an economic territory reaches (or exceeds) USD 13,000, ART pregnancy and delivery rates were not associated with GDP per capita, and ART success rates remained stable.
