RESUMO
RESEARCH QUESTION: Is there any association between pelvic pain and primary caesarean delivery for patients undergoing assisted reproductive technology (ART) treatment? DESIGN: Retrospective cohort study of nulliparous patients with singleton pregnancies who underwent ART treatment and achieved a live birth between 2012 and 2020. Cases included patients diagnosed with pelvic pain. A 3:1 ratio propensity-score-matched population of patients without a history of pelvic pain was included as the control group. Comparative statistics were performed using chi-squared test and Student's t-test. A multivariate regression analysis was conducted to evaluate the association between pelvic pain and mode of delivery. RESULTS: One hundred and seventy-four patients with pelvic pain were compared with 575 controls. Patients with pelvic pain reported a significantly longer duration of infertility compared with controls (18.98 ± 20.2 months versus 14.06 ± 14.06 months; Pâ¯=â¯0.003). Patients with pelvic pain had a significantly higher rate of anxiety disorders (115 ± 21.9 versus 55 ± 31.6; Pâ¯=â¯0.009) and use of anxiolytics at embryo transfer (17 ± 3.2 versus 12 ± 6.9; Pâ¯=â¯0.03) compared with controls. In addition, patients with pelvic pain had a higher rate of primary caesarean delivery compared with controls (59.8% versus 49.0%; Pâ¯=â¯0.01). After adjusting for multiple variables, a significant association was found between pelvic pain and increased odds of primary caesarean delivery (adjusted OR 1.48, 95% CI 1.02-2.1). CONCLUSION: Patients with pelvic pain have significantly higher odds of primary caesarean delivery compared with patients without a history of pelvic pain. The infertility outpatient setting may be uniquely positioned to identify patients at risk for undergoing primary caesarean delivery, and could facilitate earlier intervention for pelvic floor physical therapy during the preconception and antepartum periods.
RESUMO
RESEARCH QUESTION: Do the various forms of hormonal and non-hormonal contraceptives have any association with ovarian stimulation outcomes, such as oocyte yield and maturation, in patients undergoing planned oocyte cryopreservation (POC)? DESIGN: This retrospective cohort study included all patients who underwent POC cycles between 2011 and 2023. The use of types of contraception before a POC cycle was recorded. The study evaluated the median number of cumulus-oocyte complexes obtained after vaginal oocyte retrieval and the proportion of metaphase II oocytes that underwent vitrification among all the cohorts. RESULTS: A total of 4059 oocyte freezing cycles were included in the analysis. Eight types of contraceptive method were recognized in patients undergoing ovarian stimulation: intrauterine device (IUD), copper (nâ¯=â¯84); IUD, levonorgestrel low dose (<52 mg) (nâ¯=â¯37); IUD, levonorgestrel (nâ¯=â¯192); subdermal etonogestrel implant (nâ¯=â¯14); injectable medroxyprogesterone acetate (nâ¯=â¯11); etonogestrel vaginal ring (nâ¯=â¯142); combined oral contraceptive pills (nâ¯=â¯2349); and norelgestromin transdermal patch (nâ¯=â¯10). The control group included patients not using contraceptives or using barrier or calendar methods (nâ¯=â¯1220). Among all the cohorts the median number of cumulus-oocyte complexes retrieved during oocyte retrieval was comparable (Pâ¯=â¯0.054), and a significant difference in oocyte maturity rate with median number of vitrified oocytes was found (Pâ¯=â¯0.03, P < 0.001, respectively). After adjusting for confounders a multivariate analysis found no association between the type of contraceptive and proportion of metaphase II oocytes available for cryopreservation. CONCLUSIONS: Among the various forms of contraception, none was shown to have an adverse association with oocyte yield or maturation rate in patients undergoing POC.
RESUMO
STUDY OBJECTIVE: To study pregnancy outcomes after single euploid embryo transfer (SEET) in patients who underwent prior uterine septum resection to those with uteri of normal contour, without Müllerian anomalies or uterine abnormalities including polyps or fibroids, and without a history of prior uterine surgeries. DESIGN: Retrospective cohort study. SETTING: Single academic affiliated center. PATIENTS: 60 cycles of patients with prior hysteroscopic uterine septum resection who underwent an autologous SEET between 2012 and 2020 were used as the investigational cohort. A 3:1 ratio propensity score matched control cohort of 180 single euploid embryo transfer cycles from patients without a history of uterine septa were used as the control group. INTERVENTIONS: No interventions administered. MEASUREMENTS AND MAIN RESULTS: Pregnancy, clinical pregnancy loss, ongoing clinical pregnancy, and live birth rates in patients with a history of uterine septum resection compared with matched patients without Müllerian anomalies or uterine surgeries. Patients with a prior uterine septum had significantly lower rates of chemical pregnancy (58.33% vs 77.2%, p = .004), implantation (41.67% vs 65.6%, p = .001), and live birth (33.33% vs 57.8%, p = .001) per transfer. No statistical difference in clinical pregnancy loss rates was found when comparing septum patients with controls (8.33% vs 7.8%, p = .89). CONCLUSION: Patients with a history of hysteroscopic resection who undergo in vitro fertilization are more susceptible to suboptimal clinical outcomes compared with patients with normal uteri. Early pregnancy loss rates in patients with a uterine septum are higher than in those without; however, after resection, the rates are comparable. Patients born with septate uteri require assessment of surgical intervention prior to SEET, and to optimize their reproductive outcomes.

PURPOSE: To determine whether the embryonic euploidy rate and live birth outcomes following single, euploid embryo transfer (SEET) differ among women of self-reported racial and ethnic backgrounds. METHODS: This retrospective cohort study included all infertile patients of different self-reported racial backgrounds who underwent In vitro fertilization (IVF) with preimplantation genetic testing for aneuploidy (PGT-A) and an autologous single euploid embryo transfer (SEET) from December 2015 to December 2019 at a single private and academic assisted reproduction technology center. Primary outcome measures included ploidy rates among different racial groups. Secondary outcomes included clinical pregnancy, clinical pregnancy loss, and live birth rates. RESULTS: Five thousand five hundred sixty-two patients who underwent an IVF cycle with ICSI-PGT-A were included. A total of 24,491 blastocysts were analyzed. White participants had on average more euploid embryos and higher euploidy rates when compared to their counterparts (p ≤ 0.0001). However, after controlling for confounding factors, there was no association between race and the odds of having a higher euploidy rate (aOR 1.31; 95% CI 0.63-2.17, p = 0.42). A total of 4949 patients underwent SEET. Pregnancy outcomes did not differ among patients of varying self-reported races. CONCLUSIONS: Euploidy rates and pregnancy outcomes were comparable among patients of different racial backgrounds who underwent a SEET.

STUDY QUESTION: Do infertile couples who recently utilized clomiphene citrate (CC) for ovulation induction or ovarian stimulation (<90 days previously) followed by a single euploid embryo transfer (SEET) have lower implantation potential compared with patients who were not exposed to CC within 90 days before embryo transfer (ET)? SUMMARY ANSWER: There does not appear to be an association between recent CC exposure and lower implantation potential in patients who undergo a frozen embryo transfer (FET) of euploid embryos. WHAT IS KNOWN ALREADY: Clomiphene has been found to be associated with lower pregnancy rates when compared against other ovarian stimulation medications. The majority of published research about the effects of CC on implantation potential suggest an anti-estrogenic effect on the endometrium. Quality evidence and information about utilization of CC and its effect on implantation potential after euploid ETs is lacking in the literature. STUDY DESIGN, SIZE, DURATION: A retrospective cohort study with propensity score matching was carried out. We included all patients that underwent an autologous SEET from September 2016 to September 2022 at a single academic-private ART center. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study group included patients that had utilized CC during either ovulation induction cycles and/or controlled ovarian stimulation at least 90 days before FET. A propensity score-matched control group of patients that were unexposed to CC within 90 days prior to SEET was used for comparisons. The primary outcome was positive pregnancy test (defined as a positive serum ß-hCG measured 9 days after ET), with other outcomes including clinical pregnancy, ongoing pregnancy, biochemical pregnancy loss, and clinical pregnancy loss rates per SEET. Multivariate regression analyses fitted with generalized estimating equations were utilized to analyze if there was an association between CC utilization and IVF outcomes. Furthermore, the study evaluated the cumulative effect of CC and endometrial receptivity in vivo and subsequent IVF outcomes. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 593 patients with utilization of CC in <90 days before ET were compared with 1779 matched controls. Positive pregnancy test rates were comparable among the control group and the CC exposed groups, respectively (74.3% versus 75.7%, P = 0.79), as were clinical pregnancy (64.0% versus 65.0%, P = 0.60), ongoing pregnancy (51.8% versus 53.2%, P = 0.74), biochemical pregnancy loss (15.7% versus 14.03%, P = 0.45), and clinical pregnancy loss rates were also comparable among cohorts (17.1% versus 18.1%, P = 0.71). No association was found between utilization of clomiphene and lower implantation rates (adjusted odds ratio 0.95, 95% CI 0.76-1.18). Also, no differences were observed in sub-analyses based on multiple CC utilization periods. Finally, no association was found between the number of consecutive cumulative clomiphene cycles and sub-optimal IVF outcomes. LIMITATIONS, REASONS FOR CAUTION: The study has inherent bias that originated from its retrospective design. Serum levels of CC were not measured and sample size for the sub-analyses was small. WIDER IMPLICATIONS OF THE FINDINGS: There does not appear to be an association between recent CC exposure and lower implantation potential in patients who undergo a FET of euploid embryos. This finding remains consistent, even in patients who undergo multiple, consecutive clomiphene cycles prior to ET. There were no long-term effects of CC on endometrial development and clinical characteristics examined in this study. Patients that utilized CC medication prior to a SEET cycle for either ovarian stimulation or ovulation induction, can be assured that there is no evidence of a residual effect of recent CC administration that could jeopardize their pregnancy probability.

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

OBJECTIVE: To analyze the correlation between TE grading and initial ß-hCG serum level after single euploid embryo transfer. Secondarily, to explore the association between TE grading with subsequent IVF outcomes. DESIGN: Retrospective cohort analysis. SETTING: Single, academic, private infertility and assisted reproductive care institute. PATIENTS OR OTHER PARTICIPANTS: Infertility patients who underwent a single euploid embryo transfer that resulted in a positive pregnancy test. INTERVENTION(S): ß-hCG measurements. MAIN OUTCOME MEASURE(S): Correlation between TE grade with first ß-hCG measurement. Second outcome measurements included ongoing pregnancy, biochemical pregnancy loss, and clinical pregnancy loss rates. RESULTS: 2,798 cases were analyzed. A significant difference in initial ß-hCG measurement among groups (TE A: median 143.4 mIU/mL IQR 79.2-211.2; TE B: 119 mIU/mL IQR 57.1-177.8; TE C: 82.4 mIU/mL IQR 36.3-136.4, p ≤ 0.0001) was observed. There was a significant correlation found between the TE grade and ß-hCG measurements (p ≤ 0.0001, r2 = 0.10). TE grade was not associated with higher odds of biochemical pregnancy loss (TE A vs. TE B: aOR 1.01 CI95% 0.97-1.05; TE A vs. TE C: aOR 1.03 CI95% 0.98-1.08), or higher odds of clinical pregnancy loss (TE A vs. TE B: aOR 1.02 CI95% 0.98-1.05; TE A vs. TE C: aOR 1.03 CI95% 0.98-1.07). CONCLUSIONS: In patients with euploid embryos, TE grade correlates with the first pregnancy test measurement of ß-hCG. We propose this finding helps to appoint a relevant link between morphology assessment and early embryo development in vivo.

BACKGROUND: The rates of cesarean deliveries continue to increase worldwide. Previous work suggests an association between a previous cesarean delivery and reduced fertility in natural conception and in vitro fertilization treatment cycles. To our knowledge, there is no published research that explored the relationship between a previous cesarean delivery and the clinical outcomes after in vitro fertilization and the subsequent transfer of a single frozen-thawed euploid embryo. OBJECTIVE: This study aimed to investigate the relationship between the previous mode of delivery and subsequent pregnancy outcomes in patients undergoing a single frozen-thawed euploid embryo transfer after in vitro fertilization. STUDY DESIGN: A retrospective cohort study was performed at a single academic fertility center from January 2012 to April 2020. All women with a history of a live birth undergoing autologous, frozen-thawed single euploid embryo transfers were identified. Cases included patients with a single previous cesarean delivery; controls included patients with a single previous vaginal delivery. Only the first embryo transfer cycle was included. The primary outcome was the implantation rate. Secondary outcomes included ongoing pregnancy and live birth rates, biochemical pregnancy rate, and clinical miscarriage rate. RESULTS: A total of 525 patients met the inclusion criteria and were included in the analysis. Patients with a previous cesarean delivery had a higher body mass index (24.5±4.5 vs 23.4±4.1; P=.004) than those in the vaginal delivery cohort; the rest of the demographic data were otherwise similar. In a univariate analysis, the implantation rate was significantly lower in patients with a previous cesarean delivery (111/200 [55.5%] vs 221/325 [68.0%]; P=.004). After adjusting for the relevant covariates, a previous cesarean delivery was associated with a 48% reduction in the odds of implantation (adjusted odds ratio, 0.52; 95% confidence interval, 0.34-0.78; P=.002). In addition, after adjusting for the same covariates, a previous cesarean delivery was significantly associated with a 39% reduction in the odds of an ongoing pregnancy and live birth (adjusted odds ratio, 0.61; 95% confidence interval, 0.41-0.90; P=.01). There were no differences in the biochemical pregnancy rates or clinical miscarriage rates. CONCLUSION: This study demonstrated a marked reduction in implantation and ongoing pregnancy and live birth associated with a previous cesarean delivery in patients undergoing a single euploid embryo transfer. Our work stresses the importance of reducing the primary cesarean delivery rates at a national level and elucidating the mechanisms behind the substantially lower implantation rates after a cesarean delivery.

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

STUDY QUESTION: What is the impact of a late follicular phase progesterone elevation (LFPE) during controlled ovarian hyperstimulation (COH) on embryonic competence and reproductive potential in thaw cycles of preimplantation genetic testing for aneuploidy (PGT-A) screened embryos? SUMMARY ANSWER: Our study findings suggest that LFPE, utilizing a progesterone cutoff value of 2.0 ng/ml, is neither associated with impaired embryonic development, increased rate of embryonic aneuploidy, nor compromised implantation and pregnancy outcomes following a euploid frozen embryo transfer (FET) cycle. WHAT IS KNOWN ALREADY: Premature progesterone elevation during COH has been associated with lower pregnancy rates due to altered endometrial receptivity in fresh IVF cycles. Also, increased levels of progesterone (P) have been suggested to be a marker for ovarian dysfunction, with some evidence to show an association between LFPE and suboptimal embryonic development. However, the effect of LFPE on embryonic competence is still controversial. STUDY DESIGN, SIZE, DURATION: Retrospective cohort analysis in a single, academic ART center from September 2016 to March 2020. In total, 5244 COH cycles for IVF/PGT-A were analyzed, of those 5141 were included in the analysis. A total of 23 991 blastocysts underwent trophectoderm biopsy and PGT analysis. Additionally, the clinical IVF outcomes of 5806 single euploid FET cycles were evaluated. PARTICIPANTS/MATERIALS, SETTING, METHODS: Cohorts were separated in two groups: Group 1: oocytes retrieved from cycles with normal P levels during ovulation trigger (P ≤ 2.0 ng/ml); Group 2: oocytes retrieved after cycles in which LFPE was noted (P > 2.0 ng/ml). Extended culture and PGT-A was performed. Secondly, IVF outcomes after a single euploid FET were evaluated for each cohort. MAIN RESULTS AND THE ROLE OF CHANCE: Four thousand nine hundred and twenty-five cycles in Group 1 were compared with 216 cycles on Group 2. Oocyte maturity rates, fertilization rates and blastulation rates were comparable among groups. A 65.3% (n = 22 654) rate of utilizable blastocysts was found in patients with normal P levels and were comparable to the 62.4% (n = 1337) observed in those with LFPE (P = 0.19). The euploidy rates were 52.8% (n = 11 964) and 53.4% (n = 714), respectively, albeit this difference was not statistically significant (P = 0.81). Our multivariate analysis was fitted with a generalized estimating equation (GEE) and no association was found with LFPE and an increased odds of embryo aneuploidy (adjusted odds ratio 1.04 95% CI 0.86-1.27, P = 0.62). A sub-analysis of subsequent 5806 euploid FET cycles (normal P: n = 5617 cycles and elevated P: n = 189 cycles) showed no differences among groups in patient's BMI, Anti-Müllerian hormone (AMH), endometrial thickness at FET and number of prior IVF cycles. However, a significant difference was found in patient's age and oocyte age. The number of good quality embryos transferred, implantation rate, clinical pregnancy rate, ongoing pregnancy rate, multiple pregnancy rate and clinical pregnancy loss rates were comparable among groups. Of the registered live births (normal P group: n = 2198; elevated P group: n = 52), there were no significant differences in gestational age weeks (39.0 ± 1.89 versus 39.24 ± 1.53, P = 0.25) and birth weight (3317 ± 571.9 versus 3 266 ± 455.8 g, P = 0.26) at delivery, respectively. LIMITATIONS, REASONS FOR CAUTION: The retrospective nature of the study and probable variability in the study center's laboratory protocol(s), selected progesterone cutoff value and progesterone assay techniques compared to other ART centers may limit the external validity of our findings. WIDER IMPLICATIONS OF THE FINDINGS: Based on robust sequencing data from a large cohort of embryos, we conclude that premature P elevation during IVF stimulation does not predict embryonic competence. Our study results show that LFPE is neither associated with impaired embryonic development nor increased rates of aneuploidy. Embryos obtained from cycles with LFPE can be selected for transfer, and patients can be reassured that the odds of achieving a healthy pregnancy are similar to the embryos exposed during COH cycles to physiologically normal P levels.

OBJECTIVE: Genetic carrier screening has the potential to identify couples at risk of having a child affected with an autosomal recessive or X-linked disorder. However, the current prevalence of carrier status for these conditions in developing countries is not well defined. This study assesses the prevalence of carrier status of selected genetic conditions utilizing an expanded, pan-ethnic genetic carrier screening panel (ECS) in a large population of Mexican patients. METHODS: Retrospective chart review of all patients tested with a single ECS panel at an international infertility center from 2012 to 2018 were included, and the prevalence of positive carrier status in a Mexican population was evaluated. RESULTS: Eight hundred five individuals were analyzed with ECS testing for 283 genetic conditions. Three hundred fifty-two carriers (43.7%) were identified with 503 pathogenic variants in 145 different genes. Seventeen of the 391 participating couples (4.34%) were identified as being at-risk couples. The most prevalent alleles found were associated with alpha thalassemia, cystic fibrosis, GJB2 nonsyndromic hearing loss, biotinidase deficiency, and familial Mediterranean fever. CONCLUSION: Based on the prevalence and severity of Mendelian disorders, we recommend that couples who wish to conceive regardless of their ethnicity background explore carrier screening and genetic counseling prior to reproductive medical treatment.

To assess clinical outcomes of females diagnosed with Inflammatory Bowel Disease (IBD) and infertility, which underwent in vitro fertilization (IVF) with preimplantation genetic testing for aneuploidy. (PGT-A). Retrospective cohort study comparing clinical outcomes of patients with Inflammatory bowel disease who underwent IVF with PGT-A with a subsequent euploid single embryo transfer (SET) against a matched control group. Thirty-eight patients with an IBD diagnosis were compared to 114 controls. There was no significant difference in cycle outcomes among IBD and Control cohorts [implantation rate (71.0% vs. 78.0% (p = .68)], clinical pregnancy rate [50.0% vs. 60.5% (p = .68)], live birth [62.9% vs. 73.0% (p = .06)] multiple pregnancy rate [0% vs. 1.1% (p = .25)] and clinical pregnancy loss rate [10.5% vs. 5.7% (p = .54)]. An IBD diagnosis was not found to significantly modify the odds of implantation [adjusted OR = 0.6 (95% CI -1.2 to 0.8)]. Additionally, the odds of implantation in patients with IBD were not altered by having ulcerative colitis or Crohn's disease diagnosis. (OR = 0.4 95% CI 0.1-1.9). Patients diagnosed with IBD who undergo a SET have clinical outcomes comparable to the general infertile population. Patients and physicians can be reassured that an IBD diagnosis does not impair IVF treatment outcomes.SYNOPSISInfertile patients with inflammatory bowel disease who utilized a single, euploid blastocyst transfer had IVF success rates comparable to the general infertile population.

STUDY QUESTION: What is the rate of euploidy and the reproductive potential of embryos biopsied after 6 days of development? SUMMARY ANSWER: Embryos biopsied after 6 days of development have higher rates of aneuploidy; however, day 7 euploid embryos selected at transfer can achieve acceptable pregnancy rates and live birth (LB) outcomes. WHAT IS KNOWN ALREADY: Recent publications have shown promising treatment results after euploid day 7 embryo transfers (ETs), albeit these studies were limited by small sample sizes. Whereas the current clinical standard has been to discard embryos that do not reach expansion by day 6 of development, the lack of robust data surrounding the clinical utility of day 7 embryos warrants further evaluation. STUDY DESIGN, SIZE, DURATION: Retrospective cohort analysis in a single, academic in vitro fertilization (IVF) center from January 2012 to March 2018. A total of 25 775 embryos underwent trophectoderm (TE) biopsy and preimplantation genetic testing for aneuploidy (PGT-A). Additionally, the clinical IVF outcomes of 3824 single, euploid frozen embryo transfer (FET) cycles were evaluated. PARTICIPANTS/MATERIALS, SETTING, METHODS: Cohorts were segregated by day of TE biopsy following oocyte retrieval (day 5, day 6 or day 7). PGT-A was performed to identify embryonic ploidy rates. Secondly, IVF and LB outcomes after single, euploid FET were evaluated for each cohort. MAIN RESULTS AND THE ROLE OF CHANCE: A total of day 5 (n = 12 535), day 6 (n = 11 939) and day 7 (n = 1298) embryos were included in the study analysis. The rate of embryo euploidy was significantly lower in day 7 blastocysts compared to day 5 or day 6 cohorts (day 7 = 40.5%; day 5 = 54.7%; day 6 = 52.9%; (P < 0.0001)). After adjusting for age, anti-Müllerian hormone, BMI, embryo quality and number of embryos biopsied, there was a significant association between aneuploidy and embryos biopsied on day 7 when compared to day 5 biopsied embryos (OR = 1.34, CI 95% 1.09-1.45, P = 0.001) and day 6 biopsied embryos (OR = 1.26, CI95% 1.07-1.16, P < 0.001).A sub-analysis of subsequent 3824 single, euploid FET cycles (day 5: n = 2321 cycles; day 6: n = 1381 cycles; and day 7: n = 116 cycles) showed significant differences among cohorts in implantation, clinical pregnancy, LB and clinical loss rates. There was a significant decrease in the odds of implantation, clinical pregnancy and LB, but no association with clinical loss or multiple pregnancy rates in patients who utilized day 7-biopsied embryos during treatment. LIMITATIONS, REASONS FOR CAUTION: The retrospective nature of the study and potential variability in the study center's laboratory protocol(s) compared to other reproductive treatment centers may limit the external validity of our findings. Additionally, patients who transferred euploid embryos, biopsied on day 7 of development due to an absence of day 5 or day 6 counterparts, may have introduced selection bias in this study. WIDER IMPLICATIONS OF THE FINDINGS: Embryonic developmental stage, morphological grade and ploidy status are paramount factors affecting ET selection and implantation potential. This study reveals that embryos ineligible for TE biopsy on day 5 or day 6 of development may benefit from extended culture to day 7. Our study demonstrates patient benefit when extended culture to day 7 of development is routinely performed for embryos failing to meet biopsy criteria by day 5 or 6.

Embryo implantation represents the most critical step of the reproductive process in many species, to be successful requires a receptive endometrium, functional embryo at a stage of embryonic development and proper dialogue between embryonic and maternal tissues. Hatching is the process in which the blastocyst gets rid of the zona pellucida to be implemented. The failure in this factor can lead to reproductive problems, even under assisted reproduction techniques. Assisted hatching is a technique used in assisted reproduction laboratories to improve performance in the process of fecundation or in vitro fertilization. This technique is based on impairment or section of the zona pellucida using different techniques. In this review, the most common indications and techniques used to perform this procedure and improve success rates in assisted reproduction techniques are synthesized.

OBJECTIVE: Compare maternal and perinatal outcomes between emergency and electively scheduled cesarean-hysterectomy for placenta accreta spectrum (PAS) disorders. METHOD: Single-center retrospective cohort study including 125 cases of antenatally suspected and pathologically confirmed PAS disorders. Maternal and perinatal outcomes were analyzed. Multivariate logistic regression was used to test associations. Survival curves exploring risk factors for emergency birth were sought. RESULTS: 25 (20%) and 100 (80%) patients had emergency and electively scheduled birth, respectively. Emergency birth had a higher estimated blood loss (2772 [2256.75] vs. 1561.19 [1152.95], P < 0.001), with a higher rate of coagulopathy (40% vs. 6%; P < 0.001) and bladder injury (44% vs. 13%; P < 0.001); and was associated with increased rates of blood transfusion (aOR 4.9, CI95% 1.3-17.5, P = 0.01), coagulopathy (aOR 16.4, CI95% 2.6-101.4, P = 0.002) and urinary tract injury (aOR 6.96, CI95% 1.5-30.7, P = 0.01). Gestational age at birth was lower in the emergency group (31.55 [4.75] vs. 35.19 [2.77], P = 0.001), no difference in perinatal mortality was found. A sonographically short cervix and/or history of APH had an increased cumulative risk of emergency birth with advancing gestational age. CONCLUSION: Patients with PAS disorders managed in a tertiary center by a multidisciplinary team requiring emergency birth have increased maternal morbidity and poorer perinatal outcomes than those with electively scheduled birth.

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

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

OBJECTIVE: Although chromosomal heteromorphisms are commonly found in the general population, some researchers have suggested a correlation with higher rates of embryo aneuploidy. This study aimed to assess the rates of embryo aneuploidy in couples who carry a chromosome heteromorphism. METHODS: The study included couples who had G-banding karyotype testing and underwent an IVF/PGT-A cycle between January 2012 and March 2018. The participants were classified by couple karyotype: Group A: ≥1 patient reported to be a heterochromatic variant carrier; Group B: both partners reported to be "normal". We assessed the rates of aneuploidy among the groups. We ran a multivariate regression analysis to assess the relationship between heterochromatic variants and the rates of embryo aneuploidy. RESULTS: Of the 946 couples analyzed, 48 (5.0%) reported being a carrier of ≥1 heterochromatic variant. We had 869 IVF/PGT-A cycles included in the analysis (Group A: n=48; Group B: n=82). There were no significant differences in embryo ploidy rates among the groups. The heterochromatic chromosome variant was not associated with increased likelihoods of aneuploidy (OR=1.04, CI:95% 0.85- 1.07; p=0.46). Finally, the gender of the heterochromatic variant carrier had no association with increased likelihood of aneuploidy (OR 1.02, CI 95% 0.81-1.28, p=0.82). CONCLUSIONS: Our study showed no association between parental heterochromatic chromosome variants and subsequent embryo aneuploidy rates. Ploidy rates do not appear to be negatively associated with couples when at least one patient is reported to be a carrier of a heterochromatic variant on the karyotype.

OBJECTIVE: To analyze outcomes of IVF treatment among women diagnosed with an ovarian dermoid cyst (DC). METHODS: Retrospective analysis of women with an ovarian DC who underwent IVF with fresh blastocyst transfer at a single center in New York from January 2010 to March 2018. Outcomes were compared between women with conservative treatment and those with surgical excision of the DC. Multivariate logistic regression was used to assess associations between variables and the presence of a DC during treatment. RESULTS: Overall, 119 women with a DC were included. No differences were found in demographic characteristics, controlled ovarian hyperstimulation parameters, and IVF outcomes between women with an intact DC (n=65, 54.6%) and those who underwent cystectomy (n=54, 45.4%) (all P<0.05). Similarly, there was no difference in anti-MÏllerian hormone and basal antral follicle count among women with a DC (respectively, ß=-0.1, P=0.8, and ß=-1.0, P=0.28) or resected DC (respectively, ß=0.9, P=0.07, and ß=1.5, P=0.08) as compared with control women with no DC (n=352). CONCLUSION: Ovarian reserve, embryo implantation and IVF success rates were not lower in the presence of an ovarian DC. Surgical therapy, if indicated, can be safely postponed until family planning goals have been achieved.

OBJECTIVE: To study whether maternal exposure to selective serotonin reuptake inhibitors (SSRIs) has any influence on rates of blastocyst aneuploidy and/or in vitro fertilization (IVF) cycle outcomes. DESIGN: Retrospective cohort analysis. SETTING: Private and academic IVF center. PATIENT(S): Patients who underwent IVF with preimplantation genetic treatment with trophectoderm biopsy (n = 4,355 cycles) and patients who underwent a single-embryo transfer (SET) between January-2012 and June-2017 (n = 2,132 cycles). INTERVENTION(S): Comprehensive chromosome screening and euploid SET. MAIN OUTCOME MEASURE(S): Odds of embryo aneuploidy. RESULT(S): Of 19,464 embryos analyzed, 3.9% (n = 743) were exposed to a SSRI, and the remaining 96.1% (n = 18,721) were not. The embryo euploid rate was 52.1%, and the aneuploid rate was 42.5%; 5.4% of the reports were inconclusive. No differences were found in clinical and IVF characteristics among the cohorts. After controlling for cofounders, there was no statistically significant associations between exposure to SSRIs and the odds of aneuploidy (adjusted odds ratio [OR] 0.04; 95% confidence interval [CI], -0.04-0.09). In a subanalysis including 2,132 thawed SET cycles, no differences were observed in implantation rate (71.3% vs. 70.1%; OR 0.60; 95% CI, 0.60-1.47), clinical pregnancy rate (58.2% vs. 59.7%; OR 0.70; 95% CI, 0.70-1.61), loss rate (18.5% vs. 11.49%; OR 1.54; 95% CI, 0.94-2.54), or multiple pregnancy rate (0.6% vs. 0; OR 0.7; 95% CI, 0.02-7.32) between cohorts. CONCLUSION(S): Patients exposed to SSRIs in vivo are not susceptible to an increased rate of embryo aneuploidy in IVF. The IVF outcomes of patients exposed to SSRIs do not differ from those of unexposed patients.
