The Association between Embryo Development and Chromosomal Results from PGT-A in Women of Advanced Age: A Prospective Cohort Study. J Clin Med 2024; 13:626. [PMID: 38276130 PMCID: PMC10816670 DOI: 10.3390/jcm13020626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 12/19/2023] [Accepted: 01/10/2024] [Indexed: 01/27/2024] Open
Abstract
Embryo morphology and morphokinetics have been studied for their association with euploid embryos. However, the results are controversial, especially in the advanced-aged women group, when the risk of aneuploidy increases significantly. This prospective cohort study evaluated the association between embryo development between day-3 cleavage and day-5 blastocyst stages and euploidy rates, determined using preimplantation genetic testing for aneuploidy (PGT-A). Embryos from women aged 35 years and above who underwent intracytoplasmic sperm injections and PGT-A were studied. Day-3 cleavage-stage embryos were evaluated for their cell number, and day-5 blastocyst-stage embryos were evaluated for their morphological grade. Embryo development from day 3 to day 5 was categorized as either good or poor development and evaluated for its association with the PGT-A results. We evaluated 325 embryos from 101 infertile couples. It was found that 55.17% of blastocysts with good development and 29.83% with poor development were euploid. A significant association was found between embryo development and euploidy rates in advanced-aged women (p < 0.001). Also, there were significantly higher rates of euploid embryos with good blastocyst morphological grades, especially blastocyst expansion grades and trophectoderm grades. In conclusion, embryo morphokinetics shows promising results in predicting euploidy in advanced female age.

The fatty acid composition in follicles is related to the developmental potential of oocytes up to the blastocyst stage: a single-centre cohort study. Reprod Biol Endocrinol 2022; 20:107. [PMID: 35879714 PMCID: PMC9310456 DOI: 10.1186/s12958-022-00974-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 06/21/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Advanced maternal age and obesity are associated with impaired female fertility. Moreover, fatty acids (FA) in follicular fluid (FF) play important roles in oocyte maturation and embryo development. However, the effects of body mass index (BMI), age, and FF FA composition on embryo development between days 3 and 5 and blastocyst stage on day 5 are still unclear. METHODS This study included 138 patients undergoing assisted reproductive technology (ART), which were divided into three BMI groups (18.5-24.9 kg/m2 vs. 25.0-29.9 kg/m2 vs. ≥ 30.0 kg/m2) and three age-related groups (20-30 years vs. 31-34 years vs. ≥ 35 years) which were compared for ART outcomes. Further, observations were divided into quartiles based on either of three parameters related to embryo outcome, i.e. (i) embryos developing between days 3 and 5 (ED3-5) and (ii) expanded blastocysts on day 5 (EB5), both expressed proportionally to the number of oocytes with two pronuclei (2PN), as well as (iii) the embryo utilization rate (EUR). Proportions of FF FA were then compared between Q1 and Q4, representing the quartile with the worst vs. the best embryo outcome, respectively. Finally, regression models were created to assess the relationships between BMI, age, FF total FA (TFA) concentration, relative proportions of specific FA and embryo outcome. RESULTS Patients of Q1 had higher proportions of FF C20:5n-3, C22:6n-3 and total n-3 PUFA than Q4 patients. Furthermore, Q4 patients tended to be younger than Q1 patients. Within the whole cohort, the proportion of C20:5n-3 negatively correlated with ED3-5/2PN and EUR, while EB5/2PN tended to be negatively correlated with age. Regression models within the overweight and obese group confirmed the negative relation between C20:5n-3 and ED3-5/2PN, but also indicated additional associations: C18:1n-9 and C20:4n-6 were positively associated with ED3-5/2PN and EUR, respectively while the proportion of C18:0 was negatively associated with EUR. CONCLUSION The proportions of n-3 PUFA, particularly C20:5n-3 and C22:6n-3 were reduced in the patients' quartile with the best embryo outcome. This group of patients was also younger. However, the embryo quality parameters of overweight/obese patients were not associated with age but were positively associated with FF C18:1n-9 and negatively with the proportions of C18:0 or C20:5n-3. TRIAL REGISTRATION This study' registration number was B670201627735.

Abstract
We aimed to investigating the effects of metformin (MET) in combination with alpha lipoic acid (ALA) on hormonal and biochemical parameters, in polycystic ovary syndrome (PCOS) women undergoing intracytoplasmic sperm injection (ICSI). This experimental pilot study with a randomized design was carried out on 40 PCOS women in two groups: (1) MET group, administered 1,500 mg/day MET, and (2) MET (1,500 mg/day)+ALA (1,800 mg/day) group. Drugs were administered from the third day of the previous cycle until the day of oocyte aspiration (six weeks of treatment in total). MET+ALA significantly increased the number of maturated oocytes and the rate of fertilization when compared to the MET group. Combination MET+ALA could increase significantly the number of oocytes retrieval and the number of good-quality embryos. Also, the malondialdehyde (MDA) level decreased significantly in the MET+ALA group and the total antioxidant capacity (TAC) level increased significantly in the MET+ALA group compared to the MET group. Also, fasting blood sugar (FBS), insulin, luteinizing hormone (LH), and LH/follicle stimulating hormone (FSH) levels were significantly lower in the MET+ALA group. The pregnancy outcomes showed no significant difference in the rates of biochemical pregnancy, clinical pregnancy, miscarriage, and live births between the control and study groups. The combination of MET+ALA treatment could moderate the complications of PCOS and subsequently improve oocyte and embryo quality.

Abstract
Background and objective: Day-5 blastocyst embryos are usually chosen for assisted reproductive therapy. We compared the reproductive outcomes of the euploid blastocysts developed on Day 5 versus Day 6. Methods: This single-center, retrospective observational study analyzed patients aged 25–45 years, who underwent intracytoplasmic sperm injection from December 2014 to November 2018. Depending on the day of trophectoderm biopsy, patients were categorized into Day-5 and Day-6 groups. Percentages of euploid embryos were calculated for both groups, and elective single euploid blastocysts were transferred in a frozen embryo transfer (FET) cycles. The study endpoints were the comparisons of the reproductive outcomes including clinical pregnancy rate (CPR), implantation rate (IR), miscarriage rate (MR), and live birth rate (LBR) between Day-5 and Day-6 euploid FET groups. Results: A total of 801 embryos from 184 patients were evaluated [Day 5 ([Formula: see text]=769); Day 6 ([Formula: see text]=32); 42.45% were euploid] with the rate of euploidy in Day-5 and Day-6 groups at 42.52% and 40.62%, respectively. A total of 126 patients underwent FET with 126 elective single euploid embryos (Day 5: 117; Day 6: 9). For Day-5 versus Day-6 groups, a significantly higher IR (61.54% vs. 44.44%; [Formula: see text] = 0.0531), CPR (61.54% vs. 44.44%; [Formula: see text] = 0.0531), and LBR (61.54% vs. 33.33%; [Formula: see text] = 0.0014) were reported. Multivariate analysis on ANOVA suggested, comparable pregnancy rates at Day 5 and Day 6 ([Formula: see text] = 0.728). Conclusions: Day-5 euploid blastocysts seem to offer better reproductive outcomes than Day-6 euploid blastocysts. Further research is recommended to evaluate the reproductive outcomes of Day-6 blastocysts.

Front Endocrinol (Lausanne) 2021; 12:637384.

Abstract
Brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family, plays critical roles in the physiological process of oocyte mature and IVF outcomes of patients with infertility. However, the regulation of BDNF expression in the microenvironment surrounding the oocyte is still unknown. We initially predicted some microRNA (miRNA) candidates targeting bdnf with a series of bioinformatics analysis tools to determine the underlying regulatory mechanisms of BDNF, particularly the effect of miRNAs on BDNF expression. Then, we assessed whether the expression of these 14 selected miRNAs was negatively associated with BDNF expression in follicular fluid (FF) samples obtained from mature (>18 mm) or immature (<15 mm) follicles. Finally, we used the candidate miRNAs, miR-103a-3p and miR-10a-5p, to further investigate the relationship between their expression in FF and the outcomes of infertile patients undergoing IVF-ET treatment. The results of the bioinformatics analysis revealed 14 miRNAs that might directly regulate BDNF expression and might have a close relationship with oocyte development. BDNF was expressed at significantly lower levels in FF from immature follicles than in FF from mature follicles, and only the expression of miR-103a-3p and miR-10a-5p was negatively correlated with BDNF expression in FF. Moreover, in another cohort of 106 infertile women undergoing IVF-ET treatment, miR-103a-3p or miR-10a-5p expression predicted the developmental status of the corresponding oocytes in which high expression of miR-103a-3p or miR-10a-5p resulted in a poor quality of embryo on days 3 and 5 during the IVF-ET treatment. In conclusion, our study is the first to show that miR-103a-3p or miR-10a-5p negatively affects the maturation of oocytes by regulating the expression of BDNF in human FF. Additionally, the expression levels of miR-103a-3p or miR-10a-5p in FF may predict the outcomes of IVF, which are helpful for improving embryo selection and consequently the IVF success rate in the clinic.
