    Abstract The recent commercialization of the Embryo Health Score (EHS), determined through preimplantation genetic testing for polygenic conditions, offers the potential to select embryos with lower disease risk, thus potentially enhancing offspring longevity and health. Lately, Orchid Health company increased testing from less than 20 diseases to more than 900+ conditions for birth defects. However, the "geneticization" of phenotype estimates to a health state erases the environmental part, including the in vitro fertilization potential risks, questioning its scientific usefulness. EHS is utilized in countries with minimal regulatory oversight and will likely expand, while it remains illegal in other countries due to ethical and legal dilemmas it raises about reproductive autonomy, discrimination, impacts on family dynamics, and genetic diversity. The shift toward commercialized polygenic embryo screening (PES) redefines healthcare relationships, turning prospective parents into consumers and altering the physician's role. Moreover, PES could increase social inequalities, stigmatize those not born following PES, and encourage "desirable" phenotypic or behavioral traits selection, leading to ethical drift. Addressing these issues is essential before further implementation and requires a collaborative approach involving political, governmental, and public health, alongside geneticists, ethicists, and fertility specialists, focusing on the societal implications and acceptability of testing for polygenic traits for embryo selection.

    Abstract The rapidly evolving nature of the coronavirus disease 2019 (COVID-19) pandemic has resulted in the publication of a breadth of information in the field of Obstetrics and Gynecology. This article is an examination of the impacts of COVID-19 on women's health, specifically on pregnancy, fertility, and delays to care. We review, in brief, the clinical presentation, transmission, and definitions of post-COVID conditions. Additionally, this article explores the reassuring evidence published regarding the use of mRNA vaccines in preconception and fertility treatments.

    Abstract Polygenic embryo screening (PES) and its derivate the Embryo Health Score (EHS) have generated interest in both infertile and fertile populations due to their potential ability to select embryos with a reduced risk of disease and improved long-term health outcomes. Concerns have been raised regarding the potential harms of IVF itself, including possible epigenetic changes that may affect the health of the offspring in late adulthood, which are not fully captured in the EHS calculation. Knowledge of the potential impacts of the trophectoderm biopsy, which is a key component of the PES procedure, on the offsprings' health is limited by the heterogeneity of the population characteristics used in the published studies. Nonetheless, the literature suggests a possible increased risk of preterm delivery, birth defects and pre-eclampsia after trophectoderm biopsy. Overall, the risks of PES for prenatal and postnatal health remain uncertain, and further research is needed. Counselling patients regarding these risks before considering PES is important, to provide an understanding of the risks and benefits. This review aims to highlight some of these issues, the need for continued investigation in this area, and the importance of informed decision-making in the context of PES.

    Abstract Purpose: In Gonadotropin releasing hormone(GnRH) agonist IVF, after administration of human chorionic gonadotropin(HCG) triggering, there is a risk of ovarian hyperstimulation syndrome(OHSS). Few methods exist to prevent OHSS in these cases. Therefore, we investigated the use of a GnRH antagonist to decrease the risk of OHSS, due to its ability to decrease VEGF production and function.
    Method: A retrospective cohort study of 171-IVF patients at risk for developing OHSS after a GnRH agonist cycle with HCG trigger was performed from 2011 to 2019. The patient population consisted of women with an unexpected exuberant response to stimulation based on ovarian reserve testing and were triggered with hCG. Women were converted to a freeze-all cycle and received either cabergoline 0.5 mg orally alone for 7 days from the collection(Group 1, n = 123) or received cabergoline 0.5 mg orally and ganirelix, 250 mcg SC for 7-10 days(Group 2, n = 48).
    Results: Group 1 had more cases of moderate and severe OHSS than group 2-(25% vs. 10% p = 0.03, and 52% vs. 25% p = 0.001 respectively). Group 1 reported more abdominal discomfort and bloating than group 2(91% vs. 65% p < 0.001) and the presence of free fluid was more frequent in group 1 than group 2(74% vs. 35% p < 0.001). Hemoconcentration and electrolyte disturbances were less severe in group 2 than in group 1 (p < 0.001 all cases).
    Conclusion: In patients at high risk for developing OHSS after hCG trigger in a GnRH agonist cycle, the addition of GnRH antagonists in the luteal phase may reduce the risk of developing moderate and severe OHSS. The GnRH antagonist likely leads to more rapid luteolysis and down regulation of VEGF production and receptor response, thereby decreasing the hallmark increased vascular permeability.

    Abstract Objective: Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a common pathology in reproductive-aged women, although data regarding pregnancy outcomes are scarce. In the present study, we aimed to compare pregnancy and perinatal outcomes between women who suffered from IIH to those who did not.
    Methods: A retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample. All pregnant women who delivered or had a maternal death in the US (2004-2014) were included. Women with an ICD-9 diagnosis of IIH before or during pregnancy were matched to controls without IIH according to age, race, insurance type, and income quartile, in a 1:20 ratio. Pregnancy, delivery, and neonatal outcomes were compared between the two groups.
    Results: Overall, 9 096 788 deliveries were identified. Of these, 1454 women (0.016%) had a diagnosis of IIH (study group) and were compared to 29 080 women without IIH (control group). Women with IIH, compared to those without, were more likely to be obese (body mass index >30 kg/m
    Conclusion: Women with IIH had a higher incidence of obstetrical complications, including preterm deliveries, hypertensive disorders of pregnancy, and congenital anomalies.

    Abstract Objective: Transient ischemic attack (TIA) is rare in women of reproductive age. We aimed to compare perinatal outcomes between women who suffered from a TIA to those who did not.
    Methods: A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). All women who delivered or had a maternal death in the US (2004-2014) were included in the study. Pregnancy, delivery, and neonatal outcomes were compared between women with an ICD-9 diagnosis of a TIA to those without.
    Results: Overall, 9 096 788 women met the inclusion criteria. Of these, 203 women (2.2/100000) had a TIA (either before or during pregnancy). Women with TIA, compared to those without, were more likely to be older than 35 years of age, white, in the highest income quartile, be insured by private insurance and suffer from obesity and chronic hypertension. Patients in the TIA group, compared to those without, had a higher rate of pregnancy-induced hypertension (aOR 2.5, 95% CI: 1.55-4.05, P < 0.001), pre-eclampsia (aOR 3.77, 95% CI: 2.15-6.62, P < 0.001), eclampsia (aOR 28.05, 95% CI: 6.91-113.95, P < 0.001), preterm delivery (aOR 1.78, 95% CI: 1.03-3.07, P = 0.039), and maternal complications such as deep vein thrombosis (aOR 33.3, 95% CI: 8.07-137.42, P < 0.001). Regarding neonatal outcomes, patients with a TIA, compared to those without, had a higher rate of congenital anomalies (aOR 7.04, 95% CI: 2.86-17.32, P < 0.001).
    Conclusion: Women with a TIA diagnosis before or during pregnancy had a higher rate of maternal complications, including hypertensive disorders of pregnancy and venous thromboembolism, as well as an increased risk of congenital anomalies.

    Abstract Purpose: To determine the risk of not being a poor responder in ovarian stimulation (OS) for in vitro fertilization (IVF) when ovarian reserve markers are discordant-one falling within Poseidon's criteria normal range (e.g., anti-Müllerian hormone (AMH) ≥ 1.2 ng/mL or antral follicle count (AFC) ≥ 5), and the other in the poor ovarian reserve range.
    Methods: A tri-center retrospective cohort study (2015-2017) involving women with discordant AMH and AFC values undergoing their first IVF/ICSI cycle using conventional OS (cOS, ≥ 150 IU/day of follicle-stimulating hormone). Discordant serum AMH and AFC values were defined according to Poseidon's criteria (AMH < 1.2 ng/mL and AFC ≥ 5 or AMH ≥ 1.2 ng/mL and AFC < 5). Poor ovarian response (POR) was < 4 retrieved oocytes. Receiver operating characteristic (ROC) curves were used to determine AMH and AFC cut-offs for non-POR. Logistic regression analysis evaluated factors associated with non-POR.
    Results: Out of 8797 patients who underwent assessment with both AMH and AFC, 1172 (13.3%) exhibited discordant values. Of these, 854 (72.9%) had ≥ 4 oocytes retrieved. Within this group, 726 (85.0%) had "low" AMH values, whereas 128 (15.0%) had "low" AFCs. An AFC of 6 had 77% sensitivity and 52% specificity (AUC = 0.700), while AMH of 1.19 ng/mL had 31% sensitivity and 85% specificity (AUC = 0.492) for non-POR. AFC and the use of recombinant gonadotropins were positive predictors of non-POR.
    Conclusions: When serum AMH is < 1.19 ng/mL, but AFC is ≥ 6, there is a moderate likelihood of a non-POR during stimulation. Conversely, if AFC is < 5 but serum AMH is ≥ 1.19 ng/mL, the chances of non-POR are low. Among patients with discordant markers, AFC emerges as the primary predictor of oocyte yield.
