Pérez-Padilla NA, Garcia-Sanchez R, Avalos O, Gálvez J, Bian M, Yu L, Shu Y, Feng M, Yelian FD. Optimizing trigger timing in minimal ovarian stimulation for In Vitro fertilization using machine learning models with random search hyperparameter tuning. Comput Biol Med 2024; 179:108856. [PMID: 39053332 DOI: 10.1016/j.compbiomed.2024.108856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Revised: 06/15/2024] [Accepted: 07/06/2024] [Indexed: 07/27/2024]
Abstract
Various studies have emphasized the importance of identifying the optimal Trigger Timing (TT) for the trigger shot in In Vitro Fertilization (IVF), which is crucial for the successful maturation and release of oocytes, especially in minimal ovarian stimulation treatments. Despite its significance for the ultimate success of IVF, determining the precise TT remains a complex challenge for physicians due to the involvement of multiple variables. This study aims to enhance TT by developing a machine learning multi-output model that predicts the expected number of retrieved oocytes, mature oocytes (MII), fertilized oocytes (2 PN), and useable blastocysts within a 48-h window after the trigger shot in minimal stimulation cycles. By utilizing this model, physicians can identify patients with possible early, late, or on-time trigger shots. The study found that approximately 27 % of treatments administered the trigger shot on a suboptimal day, but optimizing the TT using the developed Artificial Intelligence (AI) model can potentially increase useable blastocyst production by 46 %. These findings highlight the potential of predictive models as a supplementary tool for optimizing trigger shot timing and improving IVF outcomes, particularly in minimal ovarian stimulation. The experimental results underwent statistical validation, demonstrating the accuracy and performance of the model. Overall, this study emphasizes the value of AI prediction models in enhancing TT and making the IVF process safer and more efficient.

Xie Q, Jiang W, Wei Y, Ni D, Yan N, Yang Y, Zhao C, Shen R, Ling X. Increasing dominant follicular proportion was associated with adverse IVF/ICSI outcomes in low-prognosis women undergoing GnRH antagonist protocol: a retrospective cohort study. J Ovarian Res 2024; 17:179. [PMID: 39217358 PMCID: PMC11365273 DOI: 10.1186/s13048-024-01502-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Accepted: 08/19/2024] [Indexed: 09/04/2024] Open
Abstract
PURPOSE This study aimed to examine the correlation between different dominant follicle proportions (DFPs) and outcomes of in-vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) among patients classified under POSEIDON Groups 3 and 4, who underwent gonadotropin-releasing hormone antagonist (GnRH-ant) protocols. Additionally, it sought to determine the optimal DFP threshold for trigger timing. METHODS A retrospective analysis was performed on patients classified under POSEIDON Groups 3 (n = 593) and 4 (n = 563) who underwent GnRH-ant protocols for controlled ovarian hyperstimulation (COH) between 2016 and 2022. These patients were categorized into two groups based on their DFPs, defined as the ratio of ≥ 18-mm dominant follicles to ≥ 12-mm follicles on the trigger day (DFP ≤ 40% and DFP ≥ 40%). Statistical analyses, including restricted cubic spline (RCS) and multivariate logistic regression, were employed to assess the relationship between DFP and IVF/ICSI outcomes. RESULTS Demographic characteristics of patients were similar across groups. In POSEIDON Groups 3 and 4, DFP > 40 was associated with a significant decrease in the number (No.) of oocytes retrieved, cleaved embryos, and available embryos. Moreover, following the GnRH-ant cycle, the clinical pregnancy and live birth rates in fresh embryo transfer (ET) were notably reduced in the DFP > 40 group compared with the DFP ≤ 40 group, whereas no significant differences were observed in the pregnancy outcomes of the first frozen-thawed embryo transfer (FET) between the groups. In POSEIDON Group 3, the cumulative clinical pregnancy rate (CCPR) and cumulative live birth rate (CLRB) were significantly higher in the DFP ≤ 40 subgroup than in the DFP > 40 subgroup, with a notable decrease in CLRB observed with increasing DFP levels. However, in POSEIDON Group 4, no significant differences in CCPR and CLRB were found between the groups. Logistic regression analysis identified age and the No. of oocytes retrieved as pivotal factors influencing CLRB in Group 4. CONCLUSION For patients in POSEIDON Group 3, maintaining a DFP ≤ 40 mm is crucial to achieve optimal laboratory and pregnancy outcomes by avoiding delayed triggering. However, for patients in POSEIDON Group 4, age remains a critical factor influencing CLRB regardless of DFP, although a higher No. of oocytes retrieved and available embryos with DFP ≤ 40 is beneficial.

CX43 and oxidative stress are the targets of BCB staining to predict the developmental potential of buffalo oocytes. Reprod Domest Anim 2024; 59:e14673. [PMID: 39086079 DOI: 10.1111/rda.14673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 06/28/2024] [Accepted: 07/03/2024] [Indexed: 08/02/2024]
Abstract
This study used the brilliant cresyl blue (BCB) staining method to group buffalo oocytes (BCB+ and BCB-) and perform in vitro maturation, in vitro fertilization and embryo culture. At the same time, molecular biology techniques were used to detect gap junction protein expression and oxidative stress-related indicators to explore the molecular mechanism of BCB staining to predict oocyte developmental potential. The techniques of buffalo oocytes to analyse their developmental potential and used immunofluorescence staining to detect the expression level of CX43 protein, DCFH-DA probe staining to detect ROS levels and qPCR to detect the expression levels of the antioxidant-related genes SOD2 and GPX1. Our results showed that the in vitro maturation rate, embryo cleavage rate and blastocyst rate of buffalo oocytes in the BCB+ group were significantly higher than those in the BCB- group and the control group (p < .05). The expression level of CX43 protein in the BCB+ group was higher than that in the BCB- group both before and after maturation (p < .05). The intensity of ROS in the BCB+ group was significantly lower than that in the BCB- group (p < .05), and the expression levels of the antioxidant-related genes SOD2 and GPX1 in the BCB+ group were significantly higher than those in the BCB- group (p < .05). Brilliant cresyl blue staining could effectively predict the developmental potential of buffalo oocytes. The results of BCB staining were positively correlated with the expression of gap junction protein and antioxidant-related genes and negatively correlated with the reactive oxygen species level, suggesting that the mechanism of BCB staining in predicting the developmental potential of buffalo oocytes might be closely related to antioxidant activity.

A prospective proof-of-concept trial on the effect of personalized dosages of follitropin delta in intrauterine insemination. Reprod Biomed Online 2024; 48:103603. [PMID: 38359732 DOI: 10.1016/j.rbmo.2023.103603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 09/15/2023] [Accepted: 10/04/2023] [Indexed: 02/17/2024]
Abstract
RESEARCH QUESTION What is the efficacy and safety of individualized follitropin delta dosing for ovarian stimulation in intrauterine insemination (IUI)? DESIGN This single-centre, prospective, open-label, single-cohort study involving 106 patients established an original dosing regimen based on body weight and anti-Müllerian hormone (AMH) concentrations, with adjustments based on the ovarian response from the previous IUI cycle. Each participant was enrolled in a maximum of three IUI cycles. RESULTS Mean age was 34.5 ± 4.5 years, mean weight 69.2 ± 11.2 kg, mean AMH 15.7 ± 8.6 pmol/l, mean FSH 6.3 ± 2.6 IU/l and mean antral follicle count 16.4 ± 8.2. The percentage of patients who produced more than three mature follicles was 1.9%, 0% and 1.5%, respectively, for the three IUI cycles. The percentage of patients with two or three mature follicles was 34.0%, 36.9% and 47.1% for the three IUI cycles. The clinical pregnancy rate per IUI cycle was 17.9%, 14.3% and 17.6% for the three cycles, with a cumulative clinical pregnancy rate of 40.6%. Out of 258 cycles, 43 (16.7%) resulted in clinical pregnancy, with six of those resulting in multiple pregnancies (14.0%). Two resulted in spontaneous reduction within the first trimester and four resulted in live twin births, representing only 1.6% of the total cycles. CONCLUSIONS This study is the first to utilize follitropin delta for stimulation in IUI. It demonstrates that individualized dosing is both effective and safe, resulting in satisfactory cumulative pregnancy rates and an acceptable multiple pregnancy rate, thus achieving the primary objectives of the research.

Front Endocrinol (Lausanne) 2023; 14:1167395. [PMID: 37124736 PMCID: PMC10140496 DOI: 10.3389/fendo.2023.1167395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 03/30/2023] [Indexed: 05/02/2023] Open
Abstract
Aim To study the effect of follicle sizes of different proportions on oocyte and embryo quality in young and advanced-age patients, and provide evidence for personalized protocol adjustment. Methods This was a retrospective real-world data study including a total of 11,462 patients who had started their first in vitro fertilization cycle with a gonadotropin-releasing hormone antagonist (GnRH-ant) protocol during 2018-2021. We classified patients into groups according to the size of the dominant proportion of follicles on the human chorionic gonadotropin (hCG) trigger day: Large, Medium, Small, and Equal (containing equivalent proportions of all three size categories). The Cochran-Mantel-Haenszel test by different Anti-Mullerian Hormone (AMH) and antral follicle count (AFC) was used to compare factors such as the metaphase II (MII) oocyte rate, normal fertilization rate, and two pronuclei (2PN) cleavage rate between groups. General linear model (GLM) analysis was performed for inter-group comparison of the oocyte and embryo quality. Results In patients aged < 35 years and with AMH ≥ 1.2μg/L, the MII oocyte percentages in the Large and Medium groups were significantly higher than in the Small group (P < 0.001). The germinal vesicle (GV) oocyte and unavailable oocyte percentages in the Large and Medium groups were lower than in the Small group (P < 0.001). Among patients aged ≥ 35 years with AFC < 5 and AMH ≥ 1.2μg/L, the GV oocyte percentage in the Large group was significantly lower than in the Medium group (2.54% vs. 4.46%, P < 0.001). In patients < 35 years, the GLM demonstrated that the Large and Medium groups had positively impacted on the development of MII oocyte and live birth rate(LBR) of first embryo transfer(ET)(β>0, all P value < 0.05);and had less likely to develop into unavailable oocyte, degenerated oocyte, GV oocyte and MI oocyte rates relative to the Small group(β<0, all P value < 0.05). And among patients ≥ 35 years, the Medium group had positively impacted on the development of MII oocyte and 2PN rates relative to the Small group(β>0, all P value < 0.05); and had less likely to develop into MI oocytes relative to the Small group(β<0, all P value < 0.05). The GLM indicated that AMH, along with Gn total dose, start dose, and Gn days, had significant impact on oocyte and embryo quality. For young patients, age was not a significant influencing factor, but for advanced-age patients, age influenced the outcomes. Conclusion Our analysis suggests that for young patients (< 35 years), triggering when there is a high proportion of large or medium follicles results in better quality oocytes, while for older patients (≥ 35 years), it is better to trigger when the proportion of medium follicles is no less than that of small follicles. Further research is required to confirm these findings.

Abstract
Oocytes eligible for intracytoplasmic sperm injection (ICSI) are those that have progressed through meiosis to metaphase 2 (MII). The remaining delayed mature oocytes can be injected, aiming to achieve more embryos and a better chance to conceive. We aimed to assess the outcome of delayed matured oocytes, derived from either germinal vesicles or metaphase 1 (MI), that reached maturity (MII) 24 h following retrieval. The study population consisted of 362 women who underwent 476 IVF cycles. While fertilization rates were comparable between the sibling delayed mature oocyte group compared with injection on day 0 group (58.4% vs 62%, respectively, P = 0.07), the top-quality embryo rate per injected MII day 0 oocyte was significantly higher compared with day 1 injected oocyte (57.5% vs 43.9% respectively, P < 0.001). Moreover, following fresh transfer of embryos derived from delayed mature oocytes, implantation rate and the clinical pregnancy (CPR) and live-birth rates (LBR) per transfer were 3.9%, 3.3% and 1.6% respectively. When considering the following thawed embryo transfer cycles, implantation, pregnancy and LBR were non-significantly higher (10%, 8.3% and 8.3%, respectively). Although clinical outcomes are significantly lower when using embryos derived from delayed mature oocyte to mature day 0 oocytes, the additional embryos derived from delayed mature oocytes might contribute to the embryo cohort and increase the cumulative live-birth rate per retrieval. Moreover, the embryos derived from delayed mature oocyte favour a transfer in a frozen-thawed cycle rather than in a fresh cycle.

Abstract
The aim of this study is the development of a prediction model indicating successful application of Oocyte Retrieval performed during the Luteal Phase (LuPOR) in poor responders, as defined by the retrieval of at least one MII oocyte. Recruitment included 1688 poor responders diagnosed as per Bologna Criteria, undergoing natural cycle ICSI between 2012 and 2020. Oocyte collections were performed during the follicular phase and during the luteal phase similarly. Antral Follicle Count (AFC), Estradiol (E2) levels evaluated on both trigger days prior to Follicular Phase Oocyte Retrieval (FoPOR) and LuPOR, and the number of small follicles 8–12 mm that were not aspirated during FoPOR were identified as predictive factors indicative of an efficient LuPOR practice with an Area Under the Curve (AUC) of 0.86, 0.86, 0.89 as well as 0.82 respectively. The combination of the above-mentioned characteristics into a prediction model provided an AUC of 0.88, specificity and a sensitivity of 0.73 and 0.94 respectively and an accuracy of 0.89. The model provided a positive predictive value (PPV) of 93.5% and a negative predictive value (NPV) of 46.8%. The clinical conclusion of the present study aims to be of added value to the clinician, by providing a prediction model defining the POR population benefiting from LuPOR. The high PPV of this model may renders this tool helpful for the practitioner that considers LuPOR.

Abstract
OBJECTIVE To analyze the duration of gonadotropin hyperstimulation's impacts on oocyte quality and clinical outcomes in aged in vitro fertilization (IVF) patients. MATERIALS AND METHODS This retrospective study was carried out using IVF records of the Chang Gung Memorial Hospital IVF center from January 2017 to December 2019. A total of 308 IVF cycles with patients aged 40-44 years were included. Clinical characteristics of patients who received a short controlled ovarian hyperstimulation (COH) (i.e., 6-7 days; s-COH group) or a long COH treatment (i.e., 9-10 days; l-COH group) were compared. In addition, analysis was conducted using data within two age subgroups: 40-42 years and 42-44 years subgroups. RESULTS The s-COH group received significantly lower total doses of gonadotropin and had smaller leading follicles at the time of ovulation trigger when compared to the l-COH group. The s-COH group also produced a significantly lower number of oocytes, mature metaphase II (MII) oocytes, and 2 PN zygotes compared to the l-COH group. However, there was no significant difference in the number of transferable and good-quality embryos between the two treatment groups. Likewise, the pregnancy rate and live birth rate were comparable in the s-COH and l-COH groups. Similar results were obtained when the analysis was limited to select age subgroups (i.e., 40-42 and 42-44 years subgroups). CONCLUSION While a long COH generates more oocytes per cycle, a 6-7 days COH treatment, which is at the lower end of the recommended window of stimulation, could achieve a pregnancy outcome comparable to that applied 9-10 days of COH in aged patients.

Aizer A, Lazarovich A, Dratviman-Storobinsky O, Noach-Hirsh M, Haas J, Jacob A, Raviv G, Orvieto R. Cumulative IVF outcomes after retrieval of testicular spermatozoa: should we use immotile spermatozoa for ICSI? Reprod Biomed Online 2021; 43:269-277. [PMID: 34092520 DOI: 10.1016/j.rbmo.2021.03.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 03/05/2021] [Accepted: 03/08/2021] [Indexed: 11/16/2022]
Abstract
RESEARCH QUESTION What are the cumulative clinical pregnancy rates (CPR) and live births rates (LBR) in intracytoplasmic sperm injection (ICSI) cycles using testicular motile compared with immotile spermatozoa, obtained from testicular sperm aspiration (TESA) or extraction (TESE)? DESIGN A retrospective analysis of ICSI cycles using TESA or TESE over a period of 7 years. Cycles were divided into two groups according to the motility of the retrieved spermatozoa: Group A consisted of couples with motile spermatozoa; Group B of couples with immotile spermatozoa. Group B was subdivided into two groups: B1 consisted of couples with motile spermatozoa and B2 with immotile spermatozoa after the addition of pentoxifylline. RESULTS No differences in CPR and LBR per transfer was found between the study groups after fresh embryo transfer. No pregnancies were achieved by vitrified-warmed embryo transfer in group B2. Fertilization rates decreased when using immotile spermatozoa (64.4%, 56%, 37.9%, for groups A, B1 and B2, respectively, P < 0.001). Top-quality embryo rates were higher in groups A and B1 compared with B2 (40.7% and 40.1% versus 19.1%, respectively, P = 0.015). Cumulative CPR (53%, 41.7%, 13.6% for groups A, B1 and B2, respectively, P = 0.005) and LBR (42.4%, 30%, 13.6% for groups A, B1 and B2, respectively P = 0.03) per oocyte retrieval was significantly higher when using motile spermatozoa compared with motile or immotile spermatozoa after adding pentoxifylline. CONCLUSIONS Although fertilization, top-quality embryo rates, cumulative CPR and LBR decreased when using immotile spermatozoa, ICSI is still valid; therefore, it should be considered and offered to couples before embarking on a donor sperm insemination cycle, or cryopreserving oocytes for future additional testicular sperm retrieval.

The association between level of physical activity and pregnancy rate after embryo transfer: a prospective study. Reprod Biomed Online 2021; 42:930-937. [PMID: 33832865 DOI: 10.1016/j.rbmo.2021.01.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 01/05/2021] [Accepted: 01/22/2021] [Indexed: 11/25/2022]
Abstract
RESEARCH QUESTION Is physical activity after embryo transfer, as assessed by a smart band activity tracker, associated with decreased pregnancy rates? DESIGN Prospective observational cohort study comprising infertile women aged < 38 years, who had undergone fewer than three previous embryo transfers, achieved a good ovarian response and were undergoing frozen-thawed embryo transfer in a tertiary-referral centre. A validated smart band activity tracker was used to assess physical activity level immediately after the embryo transfer and until the pregnancy test. No specific recommendations were given to participants on level or intensity of physical activity. Physicians and patients were blinded to the data stored in the pedometer. Primary outcome was ongoing pregnancy rate. RESULTS Fifty women met the inclusion criteria. Ongoing pregnancy rate was 30%. In a pooled analysis, participants walked significantly fewer steps per day on the day of embryo transfer compared with the first 2 days after embryo transfer (4075, interquatile range [IQR] 2932-5592 versus 5204, IQR4203-8584, P = 0.01). No significant difference was observed between pregnant women and non-pregnant women in the median steps per day after embryo transfer until serum beta-HCG was measured (7569, IQR 6008-10884 versus 6572.5, IQR 5299-8786, P = 0.43). No significant difference was observed in the median number of steps on the day of embryo transfer or the first 2 days after embryo transfer between pregnant and non-pregnant women. CONCLUSIONS A quantitative objective assessment of the association between physical activity and pregnancy rates after frozen-thawed embryo transfer was conducted. Ambulation after embryo transfer has no adverse effect on pregnancy rates and, therefore, women should resume regular activity immediately after embryo transfer.
